Anti-Mage
* 
Waning Rift silences Anti-Mage, preventing him from blinking away.
* However, Waning Rift can be dispelled by Manta Style.
* 
Dream Coil stops Anti-Mage from blinking, with 
Aghanim's Scepter also locks down Anti-Mage for long duration.
Phantom Assassin
* Puck relies mainly on magical burst damage, which Phantom Assassin is most vulnerable against.
* 
Phase Shift and 
Illusory Orb disjoint Stifling Dagger, also allowing to kite Phantom Assassin.
* Dream Coil will stun Phantom Assassin if she uses 
Phantom Strike to blink away.
Anti-Mage
* 
Berserker's Call prevents Anti-Mage from escaping with Blink, and works well with 
Blade Mail against Anti-Mage's relatively low health.
* 
Counter Helix often triggers even if Axe's depleted of mana, which will make Anti-Mage take more damage than he's dealing and deals pure damage, ignoring the protection from Counterspell.
* Axe's low mana pool makes him a bad target for using Mana Void.
* Axe's high base health regeneration allows him to dominate the lane against Anti-Mage, especially with a support.
Additional:
* Berserker's Call is one of the most reliable ways to lock down Anti-Mage, preventing him from 
Blinking away.
* Anti-Mage's high attack speed, along with illusions from 
Manta Style, triggers Counter Helix continuously.
* Axe's low mana pool and high health pool make 
Mana Void deal very little damage to Axe.
Phantom Assassin
* Phantom Strike's extra attack speed will cause Phantom Assassin to trigger Counter Helix more often, which can be fatal for Phantom Assassin. Jumping on Axe with Phantom Strike is not a good idea for Phantom Assassin at all as it makes her a seriously easy target for a counter-initiation with Berserker's Call and Blade Mail.
* Most of Axe's abilities pierce 
Black King Bar, allowing him to lock down Phantom Assassin at any time.
* Berserker's Call greatly reduces Phantom Assassin's ability to crit hard against Axe and may cause her to kill herself when used with Blade Mail. Berserker's Call can also affect Phantom Assassin even if she has Black King Bar active as Berserker's Call can fully pierce spell immunity, making Berserker's Call one of the best abilities in the game against heroes like Phantom Assassin who wants to kill opponents quickly without being interrupted.
* 
Culling Blade can often kill Phantom Assassin before she can do anything due to her low health and strength gain. And every time Culling Blade successfully kills Phantom Assassin or any of her teammates, Axe gains permanent armor from it, which in combination with armor items that Axe often purchases like Blade Mail, 
Crimson Guard, 
Assault Cuirass and 
Shiva's Guard can make Phantom Assassin's attacks only tickle Axe.
* 
Aghanim's Shard upgraded Counter Helix can weaken Phantom Assassin's damage output, and if her attack damage is weak, 
Coup De Grace will also suffer from attack damage reduction as well.
Additional:
* Phantom Strike's extra attack speed will cause Phantom Assassin to trigger Counter Helix more often, which can be fatal for Phantom Assassin in the early game. Jumping on Axe with Phantom Strike is not a good idea for Phantom Assassin at all as it makes her a seriously easy target for a counter-initiation with Berserker's Call and Blade Mail.
* Most of Axe's abilities pierce Black King Bar, allowing him to lock down Phantom Assassin at any time.

Anti-Mage
* Anti-Mage relies on blinking and attacking. Overgrowth prevents both.
* Be wary that he will eventually farm up a Manta Style that fully dispels Overgrowth. Good players will wait for your ultimate to use their manta. Perhaps an ally has a silence or similar that would force him to use his manta before your ultimate.
Phantom Assassin
* Overgrowth prevents Phantom Assassin from using 
Blink Strike even through her spell immunity.
* Living Armor reduces Phantom Assassin's physical damage whenever she attempts to gank an allied hero.
Anti-Mage
* Troll Warlord's passive root, high attack speed, and blind from 
Whirling Axes makes him an exceedingly difficult opponent for Anti-Mage to take down in a one-on-one fight.
* Troll Warlord's low mana causes him to take little damage from Mana Void.
Additional:
* Whirling Axes (Melee) provides a 60% miss chance, preventing Anti-Mage from burning Troll Warlord's small mana pool.
* Troll Warlord's passive root allows him to very effectively fight an Anti-Mage by preventing Anti-Mage from Blinking away. This is even more effective when combined with a 
Skull Basher or 
Abyssal Blade.
* 
Counterspell will do nothing to prevent Troll Warlord's high physical damage.
* Due to Troll Warlord's abysmal base intelligence and intelligence gain, he is one of the worst targets to use Mana Void on.
Phantom Assassin
* 
Whirling Axes (Melee) makes it hard for Phantom Assassin to land a Coup De Grace.
* Troll Warlord often buys 
Silver Edge and 
Monkey King Bar, the items that greatly help against Phantom Assassin's Blur ability.
* 
Battle Trance completely negates Phantom Assassin's large damage output, preventing Troll Warlord from dying easily. The lifesteal also allows Troll Warlord to restore much of his health.
Additional:
* Troll Warlord can build a Silver Edge or a Monkey King Bar to completely ignore 
Blur.
* Whirling Axes (Melee) provides a 60% miss chance, making a Coup de Grace critical strike very hard to land.
* Battle Trance negates Coup de Grace, preventing Troll Warlord from dying to her critical hits.
Anti-Mage
* Multiple 
Earthbinds allows Meepo to lock down Anti-Mage almost indefinitely.
* Meepo's clones can only use their mana for 
Poof, keeping their mana pool nearly full and thus making them a bad target for a Mana Void.
Additional:
* Earthbind can prevent Anti-Mage from using Blink, allowing Meepo to kill him with attacks and Ransack.
Phantom Assassin
* Heroes with high mobility can be prevented from using it to their advantage with Earthbind, even if they pack a dangerous arsenal: 
Earth Spirit, 
Ember Spirit, 
Storm Spirit, 
Nature's Prophet, 
Phantom Assassin, 
Riki, 
Anti-Mage, 
Weaver.
* See items and abilities disabled by roots
Anti-Mage
* 
Arcane Orb's pure damage, making Counterspell ineffective.
* 
Sanity's Eclipse will hit Anti-Mage while he is disabled from 
Astral Imprisonment, and forces him to take heavy damage due to his low intelligence.
* 
Essence Flux keeps Outworld Destroyer at high mana, thus greatly reducing the damage from Mana Void.
Additional:
* Counterspell doesn't work versus Arcane Orb because it does pure damage.
* Anti-Mage cannot burn all of Outworld Destroyer's mana without disables due to Essence Flux.
* Anti-Mage's Manta Style illusions are quickly destroyed by Arcane Orb.
* However, if the enemy has multiple means of removing mana, Mana Void becomes a threat to Outworld Destroyer, Anti-Mage has better mobility than Outworld Destroyer with Blink, and Counterspell blocks a large portion of the damage from Sanity's Eclipse.
Phantom Assassin
* Any heroes with low mana pools will die quickly or even instantly to Sanity's Eclipse: 
Doom, Phantom Assassin, 
Troll Warlord.
Anti-Mage
* 
Refraction protects against Anti-Mage's low burst damage, and allows her to win most fights against Anti-Mage during the early game.
* 
Meld's burst damage and armor reduction is often enough to finish off Anti-Mage before he Blinks away.
Phantom Assassin
* Heroes who can delivers a big chunk of damage in few hits will find themselves struggle against Templar Assassin's Refraction: 
Sven, Phantom Assassin, 
Ursa, 
Wraith King, 
Lifestealer
Anti-Mage
* With Aghanim's Scepter, Broodmother will gain access to 
Spinner's Snare, which will allow her to create invisible lines on her webs from 
Spin Web that will root, deal damage over time, and reveal enemy heroes if they unwittingly step on them. This allows Broodmother to keep her allies alerted on heroes who rely on invisibility-themed and movement-themed abilities and items to surprise enemy heroes and disrupt ganking attempts of enemy heroes: Phantom Assassin, 
Nyx Assassin, 
Mirana, 
Bounty Hunter, 
Templar Assassin, Riki, 
Spirit Breaker, Anti-Mage, 
Tusk, Ursa, Nature's Prophet, 
Enigma, 
Void Spirit, 
Magnus etc.
Phantom Assassin
* Phantom Assassin's single target abilities make her very helpless against swarms of Spiderlings without 
Battle Fury.
* Because Phantom Assassin is always reliant on critical strikes, Broodmother will usually have enough time to use Spin Web to save herself.
* 
Silken Bola can cripple Phantom Assassin greatly due to her being 100% reliant on physical attacks.
* Aghanim's Scepter gives Broodmother access to Spinner's Snare, which allows her to create invisible lines on her webs from Spin Web that will root Phantom Assassin, deal damage over time to Phantom Assassin and reveal Phantom Assassin if she unwittingly steps on them, disrupting her attempts to initiate or escape with with Phantom Strike while also alerting Broodmother on her attempts to ambush her and her allies.

Anti-Mage
* 
Glimpse brings Anti-Mage back after he Blinks away.
* 
Static Storm stops Anti-Mage from Blinking.
Additional:
* Similar to Queen of Pain, Glimpse can disable Blink, negating his mobility.
* However, Counterspell can negate a majority of Disruptor's damage, which may require him to have a partner to successfully kill Anti-Mage.
Phantom Assassin
* Hex abilities prevent attacking, ability and item usage, which is a severe problem for Phantom Assassin as it prevents her from using Black King Bar, the one item that helps protect her against the aforementioned dangers. Doom and 
Shadow Demon with Aghanim's Scepter also disables Phantom Assassin's Evasion and Critical Strike, removing much of her damage and survivabaility: Doom, 
Disruptor with Aghanim's Scepter, 
Dazzle with Aghanim's Shard
Anti-Mage
* Blood Rite prevents Anti-Mage from escaping with Blink.
* Blink will trigger the damage from Rupture.
* Both Blood Rite & Rupture are pure damage which can bypass Counterspell.
Phantom Assassin
* Heroes with gap-closing abilities who attempt to use them for escaping Bloodseeker will suffer serious damage from Rupture: Phantom Assassin, Anti-Mage, 
Faceless Void, Riki, 
Slark, Spirit Breaker.
Anti-Mage
* Anti-Mage usually relies on Blink to escape, but with vision from Charge of Darkness it is easier to catch him.
* Spirit Breaker could single-handedly lock Anti-Mage down for 4 seconds (or even more with lucky bashes), allowing his teammates to follow up.
* As Anti-Mage is an elusive hero who likes to farm alone, Spirit Breaker could choose to charge whenever Anti-Mage is in sight.
Phantom Assassin
* Heroes that rely on escapes to stay alive can be caught and locked down for a long time: 
Queen of Pain, Phantom Assassin
Anti-Mage
* Anti-Mage's Mana Void won't do a lot of damage because Centaur has a low mana pool. 
Mana Break is also relatively ineffective against him.
Phantom Assassin
* 
Hoof Stomp and 
Double Edge can often burst down Phantom Assassin from early to mid game.
* 
Retaliate makes it very unlikely for Phantom Assassin to win the lane against Warrunner. Double Edge can also be used to wear her down, as she has a much smaller health pool than that of Centaur Warrunner until purchasing a 
Ring of Health. 
Stifling Dagger will also trigger Retaliate and Blur cannot evade Retaliate.
* Centaur Warrunner's tankiness in combination with armour items that Axe often purchases like Blade Mail, Crimson Guard, Assault Cuirass and Shiva's Guard can make Phantom Assassin's attacks only tickle Centaur Warrunner.
* Centaur Warrunner just has to be careful about 
Fan of Knives from Aghanim's Shard and Coup De Grace, as Fan of Knives can disable Retaliate even if Centaur Warrunner is spell immune.

Anti-Mage
* 
Disruption sets up Anti-Mage for a chain disable. The illusions will deal extra damage due to Mana Break.
* 
Shadow Poison hits Anti-Mage even after he's Blinked away.
* If Shadow Demon has Aghanim's Scepter, 
Demonic Purge can break Mana Break and Counterspell, weakening both his offense and defense.
Additional:
* While it is unwise to encounter Anti-Mage alone, Disruption's considerable cast range can become a perfect setup for any hard-disable to follow up. If he is pinned down, Anti-Mage will quickly face his demise when the illusions deplete his already low mana pool. Manta Style will easily allow him to escape, however.
* The illusions can be controlled to quickly sap mana from any other target, making Anti-Mage one of the most valuable targets to disrupt.
Phantom Assassin
* Hex abilities prevent attacking, ability and item usage, which is a severe problem for Phantom Assassin as it prevents her from using Black King Bar, the one item that helps protect her against the aforementioned dangers. Doom and Shadow Demon with Aghanim's Scepter also disables Phantom Assassin's Evasion and Critical Strike, removing much of her damage and survivabaility: Doom, Disruptor with Aghanim's Scepter, Dazzle with Aghanim's Shard
Anti-Mage
* Heroes who cannot fight back during Arena of Blood in the early and mid game: 
Abaddon, Anti-Mage, 
Broodmother, 
Luna, 
Sniper, Troll Warlord, Weaver, 
Clinkz.
Phantom Assassin
* Phantom Assassin's high physical damage is greatly reduced by Bulwark.
* God's Rebuke has true strike, ignoring the evasion from Blur.
Anti-Mage
* 
Doom shuts down Anti-Mage's escape capabilities with Blink. The ability also deals pure damage, which ignores the protection from Counterspell.
* However, a well-timed Counterspell can reflect it back.
* If Doom has Aghanim's Scepter, Doom can break Mana Break and Counterspell, weakening both his offense and defense.
* Doom's low mana pool causes him to take little damage from Mana Void.
Additional:
* Doom prevents Anti-Mage from maneuvering around a fight or escaping from an initiation using Blink. Additionally, Doom deals pure damage, which is not affected by Counterspell. This can quickly whittle away Anti-Mage's naturally poor health pool.
* However, Doom must be careful when using Doom as a well-timed Counterspell can block and reflect it back against Doom himself.
* The Level 25 talent {ValueColor:1|Doom applies Break|25tal} {Symbol:Talent} will also disable Mana Break and Counterspell's passive component, which makes Anti-Mage significantly less effective in fights and more susceptible to the high magical damage of Doom's abilities and his allies.
Phantom Assassin
* Doom with the {ValueColor:1|Doom applies Break|25tal} {Symbol:Talent} talent can be useful against heroes with troublesome passive skills while also disabling them for a long time: Phantom Assassin, 
Enchantress, 
Huskar, 
Underlord.
Anti-Mage
* 
Pounce prevents Anti-Mage from using Blink, and lets him disengage from Anti-Mage if needed.
* 
Essence Shift allows Slark to permanently steal agility from Anti-Mage.
* 
Shadow Dance stops Anti-Mage from being able to fight back in a slippery situation.
Phantom Assassin
* Slark's Pounce allows him to close the gap on Phantom Assassin and prevent her from escaping with Phantom Strike.
* As a hero who typically builds Silver Edge, Slark can use it to disable Phantom Assassin's Blur and Coup de Grace, thus taking down her attack evasion and drastically reducing her damage output.
* Because Phantom Assassin is always reliant on critical strikes, Slark will have plenty of time to escape with Pounce, Shadow Dance and Silver Edge (provided that he purchased it already).
* 
Depth Shroud from Aghanim's Shard will allow Slark to save both, himself and his allies from Phantom Assassin with Shadow Dance, and to freely fightback against her without removing invisibility upon attacking.
* Essence Shift is much more harmful for Phantom Assassin than for other heroes, as losing the agility means that her physical damage will be also reduced, which can also weaken Coup de Grace if Slark manages to steal lots of agility from her.
* Overall, any attempt for Phantom Assassin to take down Slark will hurt her more than Slark.
Additional:
* Slark's Pounce allows him to close the gap on Phantom Assassin and prevent her from escaping with Phantom Strike.

* Overall, any attempt for Phantom Assassin to take down Slark will hurt her more than Slark.
Anti-Mage
* Heroes who build mana boosting items but have low mana regeneration are especially vulnerable against Mana Break and Mana Void: 
Timbersaw, Slark, 
Shadow Fiend, Clinkz, 
Bristleback Nyx Assassin, Magnus
Anti-Mage
* Although Anti-Mage can survive Luna's magical damage output with Counterspell, Luna's physical damage from 
Moon Glaives and 
Lunar Blessing can be fair enough to deal with him.
* Reckless use of Blink will allow Luna 
Eclipse can finish off Anti-Mage from early-to-mid stages of the game until Anti-Mage gets Manta Style, Aghanim's Scepter that will give him access to 
Blink Fragment and Aghanim's Shard which will allow Counterspell to weaken enemy spell damage.
* However, Luna needs to finish the match as quickly as possible, because Anti-Mage is a hero who has a big advantage in longer matches once he farms items he needs for teamfights.
Phantom Assassin
* Even though Phantom Assassin can easily kill Luna in few strikes, Luna can also do the same to Phantom Assassin if she is not careful.
* An ill-timed and ill-positioned Phantom Strike will make Phantom Assassin an easy target for counter-attack with Eclipse if she does not have Black King Bar available to use and if Phantom Assassin cannot kill Luna fast enough. This can be even better if Luna buys Aghanim's Scepter.
* Moon Glaives can ignore Blur's evasion if Luna attacks an enemy near Phantom Assassin.
* Luna can counter Blur's evasion by buying either Silver Edge, or Monkey King Bar, which are common items on Luna.
* Luna just has to be careful about Fan of Knives from Aghanim's Shard and Coup De Grace, as Fan of Knives can disable Moon Glaives and Lunar Blessing while Coup De Grace can deal serious damage to her even if she is spell immune, though this issue can be solved by buying 
Ethereal Blade, which is a situational item on Luna.
Additional:
* Even though Phantom Assassin can easily kill Luna in few strikes, Luna can also do the same to Phantom Assassin if she is not careful.
* An ill-timed and ill-positioned Phantom Strike will make Phantom Assassin an easy target for counter-attack with Eclipse if she does not have Black King Bar available to use and if Phantom Assassin cannot kill Luna fast enough. This can be even worse if Luna buys Aghanim's Scepter.
* Moon Glaives can ignore Blur's evasion if Luna attacks an enemy near Phantom Assassin. Aghanim's Shard upgraded Moon Glaives can also reduce damage from Coup De Grace and Moon Glaives Phantom Assassin inflicts on Luna and damage Spirit Phantom Assassin she is close to her. And the Aghanim's Shard upgraded Moon Glaives have true strike for their duration, which renders Blur's evasion insignificant.
* Luna can counter Blur's evasion by buying either Silver Edge, or Monkey King Bar, which are common items on Luna.
* Luna just has to be careful about Fan of Knives from Aghanim's Shard and Coup De Grace, as Fan of Knives can deal health-based damage to Luna and disable Moon Glaives and Lunar Blessing while Coup De Grace can deal serious damage to her even if she is spell immune, though this issue can be partially solved by buying Ethereal Blade, which is a situational item on Luna.
Phantom Assassin
* All assassin-type carries in a one against one situation: 
Meepo, Phantom Assassin, Riki, Ursa. Luna's only chances are that she buys Ethereal Blade or Black King Bar to gain a slight edge against them, or both items if necessary.
Anti-Mage
* Sven's 
Great Cleave can clear Anti-Mage's illusions from Manta Style and his high health pool and low mana, making Mana Void very ineffective, although keep in mind that 
Storm Hammer is extremely easy to reflect with a well-timed Counterspell.
Additional:
* Anti-Mage is fairly fragile, and cannot stand against Sven in a prolonged fight.
* Sven's Black King Bar and low base mana can protect Sven from the effects of Mana Break and Mana Void.
* Great Cleave destroys the illusions from Anti-Mage's Manta Style.
* Although Sven should be careful as a well-timed Counterspell can block and reflect Storm Hammer back at Sven.
Phantom Assassin
* Heroes who cannot prevent Sven from killing towers will often struggle from a small map very early, such as Phantom Assassin, Storm Spirit and 
Phantom Lancer.
Anti-Mage
* 
Duel renders Anti-Mage's escape capabilities with Blink and Counterspell useless. Blade Mail and 
Moment of Courage work well against Anti-Mage's relatively low health.
* A good initiation from Legion Commander and her team is enough to effortlessly kill Anti-Mage.
Additional:
* Counterspell offer no protection against Duel at all.
* Duel locks down Anti-Mage for a long duration, preventing him from escaping with Blink. One successful Duel initiation is usually enough for Legion Commander's team to kill Anti-Mage.
Anti-Mage
* Slardar deals entirely physical damage. He does not have to worry about Counterspell.
* 
Slithereen Crush and 
Bash of the Deep prevent Anti-Mage from using Blink, the latter even if Anti-Mage activates Black King Bar.
* 
Corrosive Haze allows allies to take down Anti-Mage before he has a chance to Blink, and maintains vision over him even if he does Blink away.
Additional:
* Slithereen Crush and Bash of the Deep deals physical damage, bypassing the magic resistance bonus from Counterspell
* Corrosize Haze significantly increases the damage dealt against Anti-Mage, and makes it harder for him to flee with Blink, although Anti-mage can block its casting with with Counterspell
Anti-Mage
* 
Crippling Fear makes Night Stalker one of the best early game gankers to shut down Anti-Mage.
* Night Stalker's low mana pool causes him to take little damage from Mana Void.
Phantom Assassin
* 
Firestorm can deal serious damage to Phantom Assassin during laning.
* 
Pit of Malice prevents Phantom Assassin from either escaping or engaging with Phantom Strike.
* Phantom Assassin's damage output is entirely physical, therefore 
Atrophy Aura is very hazardous for her in most of the stages, particularly since it also affects Coup De Grace, hindering Phantom Assassin's main source of damage.
* Without proper items and any area-of-effect ability/item, Phantom Assassin cannot stop Underlord and his team to escape with 
Fiend's Gate, and she has nothing to intercept Underlord and his team when they use Fiend's Gate to teleport on any area of the map outside of Fan of Knives from Aghanim's Shard.
Additional:
* Firestorm can be used to deal serious damage to Phantom Assassin during laning that ignores evasion from Blur.
* Pit of Malice prevents Phantom Assassin from either escaping or engaging with Phantom Strike.
* Phantom Assassin's damage output is entirely physical, therefore Atrophy Aura is very hazardous for her in most of the stages, particularly since it also affects Coup De Grace, hindering Phantom Assassin's main source of damage.
* Without proper items and any area-of-effect ability/item, Phantom Assassin cannot stop Underlord and his team to escape with Fiend's Gate, nor she can intercept them if Underlord chooses to teleport on any area of the map.
Phantom Assassin
* Phantom Assassin relies on her Blur to stay alive, but is very vulnerable to Sand King's heavy magic damage.
* With Burrowstrike, Sand King can often catch Phantom Assassin before she can use her Black King Bar.
* Sand King can dodge Stifling Dagger with Sandstorm.
* Phantom Assassin has a hard time killing Sand King because of his high mobility.
Anti-Mage
* Viper's skill set makes him an effective early game ganker against Anti-Mage before he is sufficiently farmed.
* Viper's 
Corrosive Skin and low mana pool causes him to take little damage from Mana Void.
* 
Nethertoxin disables Mana Break and Counterspell, weakening both his offense and defense.
Phantom Assassin
* Heroes that can apply early pressure before Phantom Assassin has farm are massive threats: 
Axe, 
Viper, Meepo, 
Jakiro, 
Pugna, Slark, 
Venomancer etc.
Anti-Mage
* Heroes that can drain mana negatively affect Viper's ability to use Poison Attack, Nethertoxin and Viper Strike: 
Lion, Anti-Mage
Phantom Assassin
* 
Sharpshooter disables both Blur and Coup De Grace, especially with the level 25 talent.
* Because Phantom Assassin is often reliant on critical strikes, Hoodwink can have enough time to simply move near a tree and escape with 
Scurry.
Additional:
* Sharpshooter disables both Blur and Coup De Grace, weakening her damage and survivability.
* Because Phantom Assassin is often reliant on critical strikes, Hoodwink can have enough time to simply move near a tree and escape with Scurry.
Phantom Assassin
* Phantom Assassin does not deal with early aggression very easily (especially when magical damage). A competent Batrider can make life very difficult with 
Sticky Napalm followed by any other spell.
Phantom Assassin
* Heroes with illusions and summons can be hard for Phantom Assassin to deal with, as she lacks any AoE abilities to deal with them without items: Broodmother, Phantom Lancer, 
Chaos Knight, 
Lycan, 
Naga Siren, 
Shadow Shaman, 
Visage, Nature's Prophet, 
Terrorblade, 
Warlock, Wraith King.
Phantom Assassin
* Many physical-only single-target heroes like Lifestealer, Sven, Wraith King, Phantom Assassin, Templar Assassin can have their damage mitigated by Cold Embrace.
Anti-Mage
* Heroes with abilities or items that can silence or disable Anti-Mage for long periods of time will prevent him from Blinking away: Lion, 
Silencer, Shadow Shaman, 
Grimstroke, 
Witch Doctor, Riki, Faceless Void, 
Skywrath Mage, 
Puck.
Phantom Assassin
* Heroes with illusions and summons can be hard for Phantom Assassin to deal with, as she lacks any AoE abilities to deal with them without items: Broodmother, Phantom Lancer, Chaos Knight, Lycan, Naga Siren, Shadow Shaman, Visage, Nature's Prophet, Terrorblade, Warlock, Wraith King.
Anti-Mage
* As a caster, Anti-Mage's Mana Break and Mana Void are highly effective against him.
Phantom Assassin
* Heroes capable of perofrming interceptions who can anticipate and counter-initiate after Phantom Assassin blinks on them with Phantom Strike will often kill her than the other way around: Axe, 
Bane, 
Dawnbreaker, 
Centaur Warrunner, Luna, 
Medusa, 
Omniknight, 
Pudge, 
Razor, Terrorblade, Underlord.
Phantom Assassin
* Heroes who just want to farm and avoid Lone Druid early will find it very hard to do so when he starts knocking on towers: Templar Assassin, Phantom Assassin, Ember Spirit, 
Morphling.
Anti-Mage
* 
Kunkka can bring Anti-Mage back with 
X Marks the Spot, effectively negating Blink or forcing him to wait out the debuff before Blinking.
Anti-Mage
* Heroes with abilities or items that can silence or disable Anti-Mage for long periods of time will prevent him from Blinking away: Lion, Silencer, Shadow Shaman, Grimstroke, Witch Doctor, Riki, Faceless Void, Skywrath Mage, Puck.
Phantom Assassin
* Despite her high mobility, 
Hex or 
Earth Spike can lock Phantom Assassin down, make her vulnerable and mitigate her damage output.
* Lion relies entirely on his abilities to be effective, rendering Phatnom Assassin's high evasion through ineffective against him. And Phantom Assassin's low health pool makes her vulnerable to Lion's magical burst without Black King Bar.
Anti-Mage
* A well-timed Counterspell reflects all targeted abilities back at Lion, potentially stunning or hexing him or even making himself burst down.
Anti-Mage
* Heroes who take a long time to become strong are in for a rough mid game, such as 
Outworld Destroyer, Magnus, Medusa, and Anti-Mage.
Anti-Mage
* A well-timed use of The Swarm provides vision over heroes with high mobility: Anti-Mage, 
Arc Warden, 
Dark Seer.
Anti-Mage
* Heroes with abilities or items that can silence or disable Anti-Mage for long periods of time will prevent him from Blinking away: Lion, Silencer, Shadow Shaman, Grimstroke, Witch Doctor, Riki, Faceless Void, Skywrath Mage, Puck.
Additional:
* Chronosphere provides excellent lockdown against Anti-Mage, allowing for reliable kills in all stages of the game.
* Time Dilation while Blink and Counterspell are on cooldown will make these abilities unusable for a long time, shutting down his mobility and defensiveness.
* Faceless Void's low mana pool makes him a poor target for Mana Void, although he is very vulnerable should Anti-Mage burn all of his mana.
Anti-Mage
* Terrorblade's 
Reflection turns Mana Break against Anti-Mage draining his mana making it useful during team fights.
Additional:
* Reflection's illusion carries Mana Break as well, making it useful to use against him.
* Anti-Mage cannot manfight Terrorblade at any stage of the game.
Phantom Assassin
* Heroes with illusions and summons can be hard for Phantom Assassin to deal with, as she lacks any AoE abilities to deal with them without items: Broodmother, Phantom Lancer, Chaos Knight, Lycan, Naga Siren, Shadow Shaman, Visage, Nature's Prophet, Terrorblade, Warlock, Wraith King.
Phantom Assassin
* Assuming they have not bought anti-evasion items, attack-dependent heroes such as Ursa, Terrorblade or Lifestealer can be a minor threat for Phantom Assassin early in the game, and may even be completely dominated by her thanks to her evasion.
Phantom Assassin
* Heroes with disables that ignore spell immunity will render Phantom Assassin completely useless in teamfights throughout the game: Axe, Enigma, 
Vengeful Spirit, Doom, Bane, 
Beastmaster, Pudge, Medusa, Warlock.
Phantom Assassin
* Heroes with illusions and summons can be hard for Phantom Assassin to deal with, as she lacks any AoE abilities to deal with them without items: Broodmother, Phantom Lancer, Chaos Knight, Lycan, Naga Siren, Shadow Shaman, Visage, Nature's Prophet, Terrorblade, Warlock, Wraith King.
Phantom Assassin
* 
Ensnare prevents using any kind of movement abiilties, Making Naga Siren good against heroes who rely on gap-closing abilities to escape: Phantom Assassin, Magnus, Slark, Riki, Faceless Void, Storm Spirit.

* Tinker can use Laser to save an ally or himself from Phantom Assassin's initiate Phantom Strike due to the blind, forcing her to use a Black King Bar to effectively initiate, Tinker can also use Warp Flare one he buys Aghanim's Shard to reverse Phantom Strike's blinking with Phantom Strike.
* Tinker almost never uses his physical attack, relying on his spell-spamming to deal damage which ignores Blur's Evasion
* Defense Matrix prevents Coup de Grace from triggering.
Anti-Mage
* Anti-Mage's high mobility from Blink and tendency to build Battle Fury makes him strong against split-pushing heroes: Nature's Prophet, 
Tinker, and Arc Warden.
Additional:
* Tinker is fragile and vulnerable against carries like Anti-Mage.
* Mana Break burns away his mana pool and deals bonus physical damage.
* Tinker's massive mana pool makes Mana Void deal large amount of damage, and can be used to cancel a 
Keen Conveyance teleport.
* Blink gives Anti-Mage many options, like disjointing Heat Seeking Missiles. He can use Blink to wait out of sight for a split pushing Tinker or chase a blinking Tinker into trees.
* Tinker doesn't want any of his spells reflected back at him through Counterspell.
Anti-Mage
* Counterspell does not protect Anti-Mage from 
Sacred Arrow.
* 
Moonlight Shadow can help her allies avoid Mana Break and Mana Void.
* Blink's cooldown isn't short enough to escape from 
Leap, especially when she has the extra charge from Aghanim's Shard.
Additional:
* Combo items for Mirana 
Rod of Atos can upgrade to 
Gleipnir and Sacred Arrow before and during Anti-Mage build item Manta Style cooldown can easy penetrates Counterspell broken.
* Charge for Leap can Mirana easily faster escaping.
* Moonlight Shadow it can disappear anytime and Anti-Mage can not fight.
Anti-Mage
* Heroes that have superior mobility that can easily catch up with Mirana even after she used Leap to escape: Anti-Mage, Queen of Pain, Storm Spirit, Riki.
Phantom Assassin
* 
Purification and 
Hammer of Purity can easily catch Phantom Assassin once she jumps with Phantom Strike in to attack.
* 
Heavenly Grace can be used to dispel slow from Stifling Dagger, and disables from the items Phantom Assassin relies on.
* Phantom Assassin depends entirely on physical attacks and her damage output is 100% physical. Therefore, since she has no any sources of magical damage output and hates going for items that deal magical damage like 
Dagon, Ethereal Blade and 
Revenant's Brooch, 
Guardian Angel will render her completely useless.
* Purification, Heavenly Grace and Guardian Angel can be used to save an allied hero before Phantom Assassin can finish them off with Coup De Grace.

* Purification, Heavenly Grace and Guardian Angel can be used to save an allied hero before Phantom Assassin can finish them off with Coup De Grace.
Anti-Mage
* Heroes who can drain mana can make Omniknight useless after he uses one or two abilities: Lion, Anti-Mage, Nyx Assassin.
Anti-Mage
* None of Anti-Mage's skills are that effective against Drow Ranger. Gust prevents him from Blinking in or out, Counterspell is totally useless against Drow's physical damage, and as she usually doesn't have a high mana pool, Mana Break and Mana Void don't do much either.
* Be careful however that Anti-Mage may eventually farm enough to Blink on top of you and kill you straight away, considering you have no natural tools to escape from him.
Phantom Assassin
* Generally, heroes that can close the gap on Drow Ranger to cancel her Marksmanship such as Phantom Assassin, Spirit Breaker, and Tusk are effective at limiting her power and bursting her down.
Anti-Mage
* Anti-Mage's Counterspell provides no protection against Clinkz's physical damage output.
* Clinkz can easily rush an 
Orchid Malevolence to prevent Blinking, although Anti-Mage can easily dispel it via Manta Style.
* Clinkz does heavy damage to towers, and can take map control away from Anti-Mage to limit the space he has to farm early game. If Clinkz is ahead he is capable of ending the game before Anti-Mage becomes a threat. He can also match Anti-Mage's ability to split push.
Phantom Assassin
* With 
Bloodthorn, Clinkz becomes a strong counter to heroes who rely on evasion and blind such as 
Windranger, Phantom Assassin, Troll Warlord and 
Keeper of the Light.
Anti-Mage
* Heroes who build mana boosting items but have low mana regeneration are especially vulnerable against Mana Break and Mana Void: Timbersaw, Slark, Shadow Fiend, Clinkz, Bristleback Nyx Assassin, Magnus
Phantom Assassin
* Heroes with high armor like 
Dragon Knight, or with abilities to cause attacks to miss like Phantom Assassin, Riki and Tinker will be hard to deal with, as Clinkz relies almost entirely on physical attacks.
Anti-Mage
* A combination of 
Soulbind and 
Phantom's Embrace can prevent Anti-Mage from casting spells.
* If Grimstroke has Aghanim's Scepter, 
Dark Portrait can reflect Anti-Mage's Mana Break, making it useful in team fights.
Anti-Mage
* Heroes with mobility spells can quickly escape from Stroke of Fate or break out of Soulbind: Anti-Mage, Queen of Pain, Morphling, Storm Spirit
Phantom Assassin
* 
Reactive Armor helps Timbersaw sustain harassment from Stifling Dagger.
* Phantom Assassin has a moderate health pool and usually appears in the front line of battle, making her vulnerable to Timbersaw's pure burst damage output.
* Timbersaw can easily escape from Phantom Assassin thanks to his 
Timber Chain.
Additional:
* Reactive Armor helps Timbersaw sustain harassment from Stifling Dagger, as well as ganking attempts.
* Phantom Assassin is a hero with moderate HP pool, and usually appears in the front line of battle. Because Blur does nothing against spells, she is vulnerable to Timbersaw's skills.
* Timbersaw can easily escape from Phantom Assassin thanks to his Timber Chain.
Anti-Mage
* Heroes who build mana boosting items but have low mana regeneration are especially vulnerable against Mana Break and Mana Void: Timbersaw, Slark, Shadow Fiend, Clinkz, Bristleback Nyx Assassin, Magnus
Anti-Mage
* In early to mid stage, Silence is also a great way to counter escape oriented heroes such as Anti-Mage, Queen of Pain, and Phantom Assassin to prevent them from escaping, provided that they don't have any basic dispels.
Phantom Assassin
* In early to mid stage, Silence is also a great way to counter escape oriented heroes such as Anti-Mage, Queen of Pain, and Phantom Assassin to prevent them from escaping, provided that they don't have any basic dispels.
Anti-Mage
* Death Prophet has a high mana pool and due to her heavy reliance on her spells, she will be a prime target for Mana Void.
* Death Prophet has less mobility than Anti-Mage due to Blink.
Anti-Mage
* Heroes who rely on physical damage output to be effective will fare badly against Muerta's 
Pierce the Veil: Phantom Assassin, Terrorblade, 
Drow Ranger, Lifestealer, Anti-Mage, 
Alchemist, Lycan, Clinkz, Sniper.
Phantom Assassin
* Heroes who rely on physical damage output to be effective will fare badly against Muerta's Pierce the Veil: Phantom Assassin, Terrorblade, Drow Ranger, Lifestealer, Anti-Mage, Alchemist, Lycan, Clinkz, Sniper.
Anti-Mage
* Anti-Mage's high magical resistance from Counterspell makes him difficult for Muerta to take down.
* Anti-Mage can escape Muerta easily with Blink, as Muerta lacks any inbuilt long disable.
* Due to Muerta's large intelligence pool and no escape abilities, Mana Break with Mana Void can kill her easily.
Anti-Mage
* Mana Break quickly eats away at Rubick's low mana pool, preventing 
Spell Steal abilities from triggering.
* Rubick's complete lack of mobility makes him very easy for Anti-Mage to chase down with Blink.
* Anti-Mage can dispel 
Fade Bolt damage reduction debuff with Manta Style or reduce it by Counterspell.
* Anti-Mage also has no useful abilities for Rubick to steal with Spell Steal.
Additional:
* Fade Bolt does little damage to Anti-Mage due to Counterspell's magic resistance.
* Most of Rubick's spells are single targets and can be reflected by Counterspell.
* The only spell that provides some utility for Rubick is Blink.
* Blink does little on its own to counter Anti-Mage when coming from behind except allowing Rubick to escape.
* Rubick can easily run out of mana to cast the spell due to Mana Break, if not dying to Anti-Mage's physical damage already.
Phantom Assassin
* Fade Bolt is not enough to burst Phantom Assassin down without the help of other stolen spells.
* 
Rubick has little armor and can be Phantom Assassin's primary target.
* 
Telekinesis is the only way for Rubick to retaliate if being jumped on, but the lockdown duration is generally not enough for Rubick to escape.
* Few of Phantom Assassin's spells grants utility for Rubick.
* Phantom Assassin's spells strengthes her assault power combined with her physical damage output, yet Rubick is not considered a physical damage dealer.
* With that said, Blur could be of use for Rubick to hide on back in teamfights waiting for the key spell without fearing of being initiated.
Anti-Mage
* Anti-Mage can close the gap with Blink. Sniper will struggle to escape once he is jumped on due to the lack of mobility.
* Counterspell reduces sniper's magic damage from 
Shrapnel and 
Assassinate. The active component can also reflect the projectile back to sniper if he dares to target Anti-Mage. This is seriously detrimental for Sniper as he is prone to buying 
Khanda to boost effects of the Assassinate.
* Sniper often relies on mana to use items for escaping, and his abilities cost a lot of mana. Mana Break drains Sniper's mana and takes away Sniper's means to disengage.
* Anti-Mage has faster farming speed. He can outfarm and get ahead of Sniper easily.
Phantom Assassin
* Sniper's lack of mobility and reliance on attack range makes him an easy target for Phantom Assassin to jump on.
Additional:
* Stifling Dagger and Phantom Strike allow Phantom Assassin to close the gap with Sniper and prevent his escape.
* Blur allows Phantom Assassin to approach Sniper while invisible and dodge much of Sniper's damage. It can also disjoint Assassinate.
* Coup De Grace quickly cuts through Sniper's low health; one or two procs will usually kill him.
* Fan of Knives from Aghanim's Shard can deal damage to Sniper's maximum health and disable 
Headshot and 
Take Aim.
Anti-Mage
* Counterspell negates Dark Willow's high magic burst damage. Its active blocks 
Cursed Crown.
* Blink allows Anti-Mage to dodge Terrorize during its long cast animation, as well as avoiding the obstacles from Bramble Maze. On the other hand, if Anti-Mage gets caught inside Bramble Maze, he's unable to Blink away.
* Dark Willow's chained magic burst requires a lot of mana, setting her up for damaging Mana Voids.
Phantom Assassin
* Heroes with high burst damage and Black King Bar can take down Dark Willow quickly: Phantom Assassin, Sven, Wraith King
Anti-Mage
* Anti-Mage can withstand magical burst damage much better than other carries, making him effective against nukers: 
Lich, 
Necrophos, 
Oracle, and 
Leshrac.
Additional:
* Although he can be effective against Anti-Mage in an aggro offlane, Lich has a hard time nuking down Anti-Mage in the midgame due to his Counterspell.
* All of Lich's abilities are also targeted, which makes it much harder to disable Anti-Mage.
* In the lategame, Anti-Mage can easily pick off Lich with Blink, and the high mana cost of Chain Frost along with Lich's large mana pool makes him vulnerable to Mana Void.
* Blink allows Anti-Mage to escape Chain Frost.
Phantom Assassin
* Phantom Assassin can easily escape Lich's slows with Phantom Strike.
* Phantom Assassin's Coup De Grace can be used to burst down the squishy Lich.
Anti-Mage
* Anti-Mage can Blink away from Cold Feet or build a Manta Style to dispel it.
* Counterspell minimizes the damage Anti-Mage takes from all of Ancient Apparition's abilities.
* Mana Break and Mana Void deal a lot of damage to Ancient Apparition due to his high mana pool.
Additional:
* Anti-Mage easily Blinks out of 
Cold Feet's freeze radius.
* Ancient Apparition lacks mobility, thus making him fall easily to Mana Void.
* Counterspell reduces all Ancient Apparition's spell damage.
Phantom Assassin
* Ancient Apparition has no escape or reliable control and is very fragile, which makes him an easy target for anyone who can get on top of him, like Phantom Assassin or Clinkz.
Anti-Mage
* Thanks to Counterspell's magic resistance, Anti-Mage has a good chance of surviving a Blast Off combo.
* Anti-Mage is a natural Manta Style carrier, meaning he can dispel the silence from Blast Off and blink away when Techies initiates on him.
Anti-Mage
* Counterspell will reflects from Dispose. Counterspell timing well can not throw from Dispose endured position and Dispose will blocked.
Phantom Assassin
* Blur makes it hard for Monkey King to stack Jingu Mastery.
* Phantom Strike allows Phantom Assassin to blink directly to Monkey King during Wukong's Command, bypassing all his clones.
* Coup de Grace's high damage can kill Monkey King quickly, thus ending Wukong's Command prematurely.
Anti-Mage
* Because of the high mana cost of 
Ball Lightning, Storm Spirit is often vulnerable to Mana Void.
* Mana Break diminishes Storm Spirit's mobility with Ball Lightning, and Anti-Mage can catch him with Blink over short distances.
* Almost all of Storm Spirit's damage is magical, which is severely reduced by Counterspell.
* Storm Spirit has a very large mana pool which means Anti-Mage can do large amounts of damage to him with Mana Break and Mana Void.
Additional:
* Mana Break can quickly burn Storm Spirit's mana, preventing him from escaping.
* Blink allows Anti-Mage to catch up to Storm Spirit when he tries to use his Ball Lightning to escape.
* Mana Void deals massive damage to Storm Spirit as well as his teammates, as Storm Spirit depletes his mana pool by using Ball Lightning.
* Counterspell's passive magic resistance reduces much of Storm Spirit's magical damage dealt to Anti-Mage, and the active aspect may even make Storm Spirit disable himself.
Phantom Assassin
* Heroes with illusions and summons can be hard for Phantom Assassin to deal with, as she lacks any AoE abilities to deal with them without items: Broodmother, Phantom Lancer, Chaos Knight, Lycan, Naga Siren, Shadow Shaman, Visage, Nature's Prophet, Terrorblade, Warlock, Wraith King.
Anti-Mage
* Anti-Mage's high mobility from Blink and tendency to build Battle Fury makes him strong against split-pushing heroes: Nature's Prophet, Tinker, and Arc Warden.
Phantom Assassin
* Nature's Prophet's low mobility and health pool allow Phantom Assassin to destroy him in the early game.
* Phantom Strike allows Phantom Assassin to jump in and out of 
Sprout, provided she has vision.
Anti-Mage
* Mana Break reduces Snapfire's already low mana pool.
* Blink allows Anti-Mage to avoid being hit by 
Lil' Shredder and 
Mortimer Kisses.
Anti-Mage
* Mana Break is very effective against Tusk, as he has a very low mana pool.
* Blink allows Anti-Mage to escape from an incoming Snowball.
* Counterspell can reflect the Snowball back onto Tusk.
Anti-Mage
* Because Queen of Pain's spells cost a decent amount of mana, Anti-Mage can easily use Mana Void if she spams her spells recklessly.
* Anti-Mage has similar mobility through Blink, which can allow him to catch up to or flee from her.
* Counterspell will reduce the damage done by Shadow Strike and Scream of Pain. Additionally, its active component also reflects Shadow Strike back at her if Anti-Mage times it right.
Anti-Mage
* Anti-Mage Blinks directly into 
Magnetic Field, bypassing its protection.
* Anti-Mage's high mobility allows him to deal with 
Tempest Double while it is split-pushing.
Additional:
* Arc Warden's high reliance on casting abilities leads him to be dependent on mana, which Anti-Mage can quickly burn with Mana Break.
* Blink mitigates the threat of Flux slow and allows Anti-Mage to close the distance between himself and Arc Warden.
* Anti-Mage's ability to farm quickly allows him keep up with Arc Warden's farm while also de-pushing the lanes Arc Warden shoves in with his Tempest Double.
* Anti-Mage also frequently buys Manta Style, and can use it so dispel Arc Warden's items that can threaten an Anti-Mage like Bloodthorn.
* Counterspell significantly reduces the effectiveness of Arc Warden's magical damage.
* However, do keep in mind that when Arc Warden has a Black King Bar, jumping on him alone may not be the best idea for Anti mage as it could put him in a bad position, while Arc Warden summons his doubles and rain damage into him.
Anti-Mage
* Mana Break quickly eats away at Bristleback's small mana pool, preventing him from spamming 
Viscous Nasal Goo and 
Quill Sprays.
* Bristleback has no innate mobility. Bristleback is easily kited by Blink, ignoring the protection from 
Bristleback.
Additional:
* Mana Break removes both a percentage and flat amount of your mana, preventing Bristleback from using abilities in the lane.
* Blink Anti-Mage has very high mobility with this skill, and can easily escape from Bristleback since he has no way to prevent his blink. He can also use this offensively to get in front of Bristleback during fights.
Phantom Assassin
* Heroes with disables that ignore spell immunity will render Phantom Assassin completely useless in teamfights throughout the game: Axe, Enigma, Vengeful Spirit, Doom, Bane, Beastmaster, Pudge, Medusa, Warlock.
Additional:
* If Phantom Assassin jumps on Pudge first with Phantom Strike, she will be a very easy target for Pudge's 
Meat Hook and 
Dismember combo.
* Even though it can deal damage based on Pudge's max health, Fan of Knives from Aghanim's Shard cannot disable Pudge's 
Flesh Heap as Flesh Heap is one of the few passive abilities that cannot be disabled by break.
* Both Meat Hook and Dismember ignore spell immunity which allows Pudge to disable Phantom Assassin even while she has Black King Bar active.
* Pudge occassionally buys armor items like Blade Mail, which in combination with many stacks from Flesh Heap can make Phantom Assassin have little effect against Pudge.
Anti-Mage
* If Meat Hook is used before Blink, Anti-Mage may be able to escape Pudge's grasp by blinking to safety.
* Counterspell grants Anti-Mage a large degree of magic resistance, a damage type Pudge is highly reliant on to secure kills. This makes Anti-Mage a bad target for Pudge. The active can also block Dismember if timed correctly.
* Mana Break can quickly drain Pudge's low supply of mana, which may render Meat Hook and Dismember unusable.
Phantom Assassin
* Generally heroes who don't rely on magical damage, such as Sven, Phantom Assassin, and Outworld Destroyer, as they can practically ignore Flesh Heap's damage block.
Phantom Assassin
* Jakiro's reliance on his abilities can cause struggles for heroes who rely on evasion or blinds to get upper hand: Phantom Assassin, Windranger, Riki, Troll Warlord, Keeper of the Light.
Anti-Mage
* Blink allows Anti-Mage to both, escape from Jakiro and to hunt down Jakiro, who has no way to escape without items.
* Counterspell protects Anti-Mage against Jakiro's mostly-magical damage.
* Both Mana Void and 
Mana Burn is very hazardous for Jakiro because of his high mana.
Phantom Assassin
* Heroes with good mobility to avoid Jakiro's abilities and with good chase to punish Jakiro from pushing a tower: 
Bloodseeker, Ember Spirit, 
Juggernaut, Phantom Assassin, Weaver.
Anti-Mage
* Ogre Magi only deals magical damage, which Anti-Mage is exceptionally resistant due to Counterspell.
* Anti-Mage dispels 
Ignite with Manta Style.
* Ogre Magi has a very large mana pool which means Anti-Mage can do large amounts of damage to him with Mana Break and Mana Void.
Additional:
* Anti-Mage can kite Ogre Magi who has low mobility by Blink and his intelligence gain and build making Mana Void deal more damage.
* Counterspell well timed makes harass Fireblast and Ignite.
Anti-Mage
* Zeus almost exclusively relies on magical damage, which is heavily reduced by Counterspell.
* Zeus' complete lack of mobility makes him very easy for Anti-Mage to chase down with Blink.
* Zeus likes to stand in the back during team fights, but Anti-Mage can easily Blink to close the distance.
Additional:
* Anti-Mage can burn mana, which is a big problem for a spellcaster like Zeus that heavily relies on it.
* Counterspell decreases magical damage taken from Zeus.
* Zeus' high intelligence and mana pool makes him a perfect target for Mana Void.
Anti-Mage
* A well-timed Counterspell can turn Bounty Hunter's mobility against him, and prevents him from escaping with Shadow Walk due to the True Sight it provides.
* Counterspell also reflects Shuriken Toss, reflecting the stun back to Bounty Hunter.
* Mana Break can drain mana from Bounty Hunter, making him unable to use Shadow Walk to save himself.
* Anti-Mage often buys Manta Style, which can dispel Track.
Anti-Mage
* Anti-Mage's mobility and magic resistance make him nearly impossible to kill alone.
* Invoker's spells cost a lot of mana, and Invoker himself has a lot of mana. This means Invoker and his team are vulnerable to Mana Void's heavy damage.
* Blink allows Anti-Mage to escape from Invoker's combo if he doesn't have disables.
Anti-Mage
* 
Tombstone's zombies rarely inhibit Anti-Mage, as he can either Blink away or onto the Tombstone and destroy it.
Anti-Mage
* Mana Break drains Abaddon's mana, preventing him from using 
Aphotic Shield to zone out enemies in lane.
* Counterspell decreases the amount of damage received from Aphotic Shield and 
Mist Coil.
Anti-Mage
* Anti-Mage can Blink into or out of 
Power Cogs, negating Clockwerk's initiation and bypassing his defenses.
Additional:
* Anti-Mage can easily Blink out of Power Cogs, escaping any ganking or initiation attempts.
* Mana Break depletes Clockwerk's much-needed mana.
* Counterspell makes Clockwerk's very low damage output only tickle Anti-Mage.
Phantom Assassin
* Phantom Strike allows Phantom Assassin jump directly to Io.
* Coup de Grace can make a short work of Io's low health and armor.
Anti-Mage
* 
Echo Stomp and 
Earth Splitter's long cast times give Anti-Mage plenty of time to Blink away.
Anti-Mage
* Heroes who rely on magical damage resistance may have a hard time laning against Dazzle as all of Dazzle's abilities deal physical damage instead of magical: Anti-Mage, Huskar, Viper.
Phantom Assassin
* Hex abilities prevent attacking, ability and item usage, which is a severe problem for Phantom Assassin as it prevents her from using Black King Bar, the one item that helps protect her against the aforementioned dangers. Doom and Shadow Demon with Aghanim's Scepter also disables Phantom Assassin's Evasion and Critical Strike, removing much of her damage and survivabaility: Doom, Disruptor with Aghanim's Scepter, Dazzle with Aghanim's Shard
Anti-Mage
* Although Counterspell's passive component doesn't protect Anti-Mage from the physical damage nukes from Poison Touch and Shadow Wave, a well-timed use of it will reflect Poison Touch back to Dazzle, slowing him in the process.
* This can be even more dangerous if Dazzle has an Aghanim's Shard, as Counterspell will reflect the hex back to Dazzle.
* Mana Break drains mana, which can be a problem for Dazzle, as all of his abilities have a high mana cost. This makes him especially vulnerable to Mana Void.
Phantom Assassin
* Dazzle's lack of a true disable makes him a relatively vulnerable target for Phantom Assassin.
* Coup de Grace will often kill Dazzle's teammates before he has a chance to use 
Shallow Grave.
Phantom Assassin
* 
Laguna Blade is one of the best tools to kill Phantom Assassin before she can do anything in early-to-mid game due to its high magical (pure with Laguna Blade damage is Pure and pierces Spell Immunity talent) burst damage.
* Blur offers no protection against Lina's abilities. Likewise, Lina can counter Blur's evasion by buying either Silver Edge or Monkey King Bar.
* Lina just has to be careful about Fan of Knives from Aghanim's Shard and Coup De Grace, as Fan of Knives can deal pure damage to Lina and disable 
Fiery Soul awhile Coup De Grace can deal serious damage to her even if she is spell immune, which may force Lina to buy Ethereal Blade to deal with Phantom Assassin.
Additional:
* Laguna Blade is one of the best tools to kill Phantom Assassin before she can do anything in early-to-mid game due to its high magical (pure with Laguna Blade damage is Pure and pierces Spell Immunity talent) burst damage.
* Blur offers no protection against Lina's abilities. Likewise, Lina can counter Blur's evasion by buying either Silver Edge or Monkey King Bar.
* Lina just has to be careful about Fan of Knives from Aghanim's Shard and Coup De Grace, as Fan of Knives can deal pure damage to Lina and disable Fiery Soul awhile Coup De Grace can deal serious damage to her even if she is spell immune, which may force Lina to buy Ethereal Blade to deal with Phantom Assassin.
Anti-Mage
* Blink allows Anti-Mage to get on top of Lina and deal damage with his Mana Break.
* Counterspell makes Anti-Mage tanky against Lina's heavy magic damage. It can also be used block and reflect Laguna Blade.
* Mana Void is very hazardous for Lina, who has a high mana pool and quickly depletes it during fights.
Phantom Assassin
* Fragile support heroes are all ideal targets for the Phantom Assassin. Heroes such as 
Lina and Witch Doctor are all prime targets that may not be able to react quickly and fight back due to Phantom Assassin's sudden appearance.
Phantom Assassin
* Heroes that can easily bypass Chen's creeps to get to Chen: Riki, Tusk, Clinkz, Sniper, Slark, Phantom Assassin, Void Spirit, Storm Spirit, Ember Spirit, Earth Spirit, Spirit Breaker.
Anti-Mage
* Heroes that can jump on her: Slark, Queen of Pain, Anti-Mage
Anti-Mage
* Heroes with considerable mobility can easily escape from a rolling Pangolier: Anti-Mage, Queen of Pain, Void Spirit, Storm Spirit, Ember Spirit, Earth Spirit, moreover, if a player is familiar with how Rolling Thunder works, they can adjust their movement to avoid it entirely and of course outplay the Pangolier player.
Phantom Assassin
* Heroes with Evasion or abilities that cause Tiny to miss like Phantom Assassin and Tinker are very effective because of Tiny's low attack speed. Additionally, Monkey King Bar is not a good item for Tiny because of its reliance on high attack speed to proc for magical damage.
Anti-Mage
* Heroes who build mana boosting items but have low mana regeneration are especially vulnerable against Mana Break and Mana Void: Timbersaw, Slark, Shadow Fiend, Clinkz, Bristleback Nyx Assassin, Magnus
Anti-Mage
* Heroes who build mana boosting items but have low mana regeneration are especially vulnerable against Mana Break and Mana Void: Timbersaw, Slark, Shadow Fiend, Clinkz, Bristleback Nyx Assassin, Magnus
Additional:
* Anti-Mage can survive against Magnus's 
Reverse Polarity thanks to the high magic resistance from Counterspell.
* Should Anti-Mage survive Magnus's Reverse Polarity and 
Skewer, Magnus will have exhausted most of his skills and items, preventing him from defending himself against any counter initiation or a follow-up from a blink escape.
* Mana Break can deplete Magnus's much needed mana.
* Anti-Mage's Blink will make him a very hard target or Magnus to use Reverse Polarity on, having to solo ult him later on in the game or leave him out of the Reverse Polarity.
* Overall, any attempt for Magnus to gank Anti-Mage will hurt him more than it will hurt Anti-Mage.
Anti-Mage
* Anti-mage is potentially good against Ember Spirit since he can burn Ember Spirit's mana, prevent him from escaping or using his skill. Anti-Mage has high magic resistance, which will reduce most of the damage from Ember Spirit's skill set. However, Anti-Mage lacks any form of stuns or lockdowns, and may struggle to kill Ember Spirit if he still has some mana left.
Anti-Mage
* Anti-Mage can withstand magical burst damage much better than other carries, making him effective against nukers: Lich, Necrophos, Oracle, and Leshrac.
Additional:
* Counterspell severely reduces Leshrac's magical damage.Counterspell also impacted reflect Lightning Storm and send back to Leshrac's also affected from movement speed.
* Leshrac already burns through his own mana with Pulse Nova, Mana Break will burn through even more.
* Leshrac's high mana pool will increase the amount of damage Mana Void does to him when his mana is low.
Phantom Assassin
* Assuming they have not bought anti-evasion items, attack-dependent heroes such as Ursa, Terrorblade or Lifestealer can be a minor threat for Phantom Assassin early in the game, and may even be completely dominated by her thanks to her evasion.
Anti-Mage
* Huskar does not need any mana to fight Anti-Mage as most of his skills cost HP instead. He is a good counter to take away Anti-mage's farm in early to mid-game. He, however, struggles to kill Anti-Mage in the late game.
Additional:
* Huskar is not very reliant on mana to cast his spells, therefore, Mana Break is not very effective against him.
* Huskar also has low mana pool, he will take less damage once his mana pool is completely depleted. Mana Void is also ineffective against him.
* Huskar comes online earlier than Anti-Mage, and can take over the game before Anti-Mage can farm up.
Anti-Mage
* Heroes with illusions can overwhelm Huskar: Phantom Lancer, Anti-Mage, Arc Warden, Chaos Knight.
Phantom Assassin
* Carries that can out damage Huskar will do well against him: 
Legion Commander, Faceless Void, Troll Warlord, Phantom Assassin.
Anti-Mage
* Heroes with escaping and disjointing abilities can be good against Juggernaut:Anti-Mage Riki, Queen of Pain, Puck, Storm Spirit, Ember Spirit, Slark etc.
Phantom Assassin
* With Aghanim's Scepter upgraded 
Infest, Lifestealer can use it on enemy heroes to attack them and disarm them from inside, even if they are spell immune, which can give him the edge over the heroes he's weak against like Ursa, Phantom Assassin, Terrorblade or Troll Warlord.
Anti-Mage
* Heroes with escape abilities: Anti-Mage Dark Seer Slark Storm Spirit Windranger Weaver can kite Lifestealer due to him having no lockdown.
Phantom Assassin
* Lifestealer, at even farm levels, will often fall against other man-fighting non-Strength cores like Ursa, Phantom Assassin or Troll Warlord as he cannot truly rely on sustain from 
Feast.
Additional:
* 
Rage does absolutely nothing against Phantom Strike with items.
* Feast and 
Ghoul Frenzy are very difficult to utilise thanks to Blur.
* Lifestealer generally wants to buy items that make him hard to kill, not an Monkey King Bar which only offers damage.
Phantom Assassin
* Heroes with illusions and summons can be hard for Phantom Assassin to deal with, as she lacks any AoE abilities to deal with them without items: Broodmother, Phantom Lancer, Chaos Knight, Lycan, Naga Siren, Shadow Shaman, Visage, Nature's Prophet, Terrorblade, Warlock, Wraith King.
Anti-Mage
* Anti-Mage commonly builds Battle Fury, which can deal with Phantasm illusions easily.
* Counterspell, if timed right, will turn Chaos Bolt against Chaos Knight, and can set up for a kill if he is not careful.
* Even if Counterspell is on cooldown, Blink can almost always dodge a Chaos Bolt because of its slow projectile.
* Mana Break will quickly drain Chaos Knight's low amount mana.
* However, beware Anti-Mage is fairly fragile and cannot withstand heavy incoming physical damage at any points in the game, which Chaos Knight excels at. A good player will bait out Counterspell, and retaliate once it's over.
Anti-Mage
* Keeper of the Light can stall pushes with 
Illuminate. This makes him strong against pushing heroes: Terrorblade Naga siren Nature's Prophet and Anti-Mage
Phantom Assassin
* Heroes which rely exclusively on right clicks will struggle somewhat against Blinding Light: Phantom Assassin, Wraith King, Medusa
Anti-Mage
* Being an intelligence caster hero, Ezalor usually has a high mana pool and low health and armor, making him a prime target for Mana Void
* Ezalor's Illuminate damage and Solar Bind's magic resistance reduction are greatly reduced thanks to Counterspell. Counterspell can also block and reflect Solar Bind if timed properly.
* Anti-Mage usually is not hampered by Solar Bind or Will-O-Wisp thanks to Blink.
* However, despite all of this, if Keeper of the Light is played carefully and tops off his team's mana at all times, Anti Mage will not be able to get off a good Mana Void.
* By the same token once Keeper of the Light gets a 
Octarine Core, he can spam Charka Magic to keep his own mana ful
Phantom Assassin
* Heroes with teleports to escape Solar Blind and Will-O-Wisp: Phantom Assassin, Puck, Queen of Pain, Storm Spirit
Anti-Mage
* Heroes with abilities or items that can silence or disable Anti-Mage for long periods of time will prevent him from Blinking away: Lion, Silencer, Shadow Shaman, Grimstroke, Witch Doctor, Riki, Faceless Void, Skywrath Mage, Puck.
Additional:
* Anti-Mage can use neither Blink nor Manta Style to escape from Smoke Cloud.
* Even if he activates a Black King Bar, his Manta Style illusions will still be blinded by Smoke Cloud.
* Riki has a very small mana pool and generally doesn't buy many items that increase it, making Mana Void ineffective.
Phantom Assassin
* 
Blink Strike does not grant Riki a mobility advantage over Phantom Assassin, as her Phantom Strike serves the same purpose, but with a higher range.
* A Carry Riki usually has a hard time dealing with Blur, as a Monkey King Bar or Bloodthorn are unfavourable item picks for him (or, even more unlikely, a Silver Edge).
* A Black King Bar is a very common pick for Phantom Assassin, fully countering 
Smoke Screen and 
Diffusal Blade while activated.
Phantom Assassin
* Heroes that can apply early pressure before Phantom Assassin has farm are massive threats: Axe, Viper, Meepo, Jakiro, Pugna, Slark, Venomancer etc.
Anti-Mage
* Venomancer's damage-over-time abilities do little damage against Counterspell.
* Blink helps Anti-Mage get away from Venomancer's slows.
Additional:
* Counterspell provides magic resistance, diminishing the effectiveness of Venomancer's spells.
* Venomancer's lack of hard disable allows Anti-Mage to use Blink, circumventing the slows Venomancer depends on.
Phantom Assassin
* Heroes with heavy early and mid-game magical damage are also problematic for Phantom Assassin due to being able to easily kill her before she can gain an item advantage over them: Lina, Necrophos, Nyx Assassin, 
Gyrocopter, Jakiro, 
Death Prophet.
Anti-Mage
* Mana Break makes Gyrocopter, who has low mana pool, unable to use his abilities that most of his damage output depends on.
* Counterspell negates magical damages from Gyrocopter and it can also reflect Homing Missile back to himself.
* Anti-Mage can easily escape from Gyrocopter's attack range and Call Down with Blink.
Phantom Assassin
* Heroes that rely on physical damage are ineffective against Dragon Knight due to his high armor: Phantom Assassin,Bloodseeker, Lifestealer, Troll Warlord, Sven
Anti-Mage
* Counterspell can helpful blocked off to 
Dragon Tail.
Additional:
* Counterspell makes Anti-Mage exceptionally resistant to Breathe Fire, Dragon Tail, Fireball (requires Aghanim's Shard) and Elder Dragon Form's attacks. Its active component also blocks and reflects Dragon Tail back at Dragon Knight.
* Mana Break drains Dragon Knight's small mana pool, although it won't affect Dragon Knight much if he is in his Elder Dragon Form.
Phantom Assassin
* Heroes that can apply early pressure before Phantom Assassin has farm are massive threats: Axe, Viper, Meepo, Jakiro, Pugna, Slark, Venomancer etc.
Anti-Mage
* Pugna only deals magical damage, which Anti-Mage is exceptionally resistant due to Counterspell.
* Anti-Mage can dispel 
Decrepify with Manta Style.
* Pugna has a very large mana pool. This allows Anti-Mage to constantly deal bonus damage to Pugna with Mana Break and devastate Pugna's entire team with Mana Void.
Additional:
* Since Pugna relies on his teammates for protection, it is fairly common for Anti-Mage to get multiple kills with a single use of his Mana Void on Pugna if he's missing a considerable portion of his mana.
* Pugna's massive mana pool will result in Anti-Mage's Mana Break almost always dealing the bonus damage from the mana burn.
* Counterspell negates a large amount of Pugna's damage, as most of Pugna's damage comes from his spells.
* Blink can be used to get out of a bad situation, and Pugna has no way to prevent him from casting it.
Phantom Assassin
* Heroes with illusions and summons can be hard for Phantom Assassin to deal with, as she lacks any AoE abilities to deal with them without items: Broodmother, Phantom Lancer, Chaos Knight, Lycan, Naga Siren, Shadow Shaman, Visage, Nature's Prophet, Terrorblade, Warlock, Wraith King.
Anti-Mage
* Mana Break prevents Warlock from casting his spells, particularly in the laning phase.
* Blink allows Anti-Mage to escape from Upheaval.
* Counterspell reduces damage from Shadow Word and Warlock's Golem's 
Permanent Immolation passive. Additionally, it can reflect Shadow Word and Fatal Bonds.
* Mana Void deals heavy damage after Anti-Mage has drained Warlock's large mana pool.
Phantom Assassin
* Heroes with single-target abilities will be overwhelmed by Lycan and his summons: Wraith King, Bane, Phantom Assassin.
Phantom Assassin
* Phantom Assassin's Blur is a real problem for Lycan, as he relies entirely on direct attacks to deal damage.
Phantom Assassin
* With 
Normal Punch from Aghanim's Scepter, Dark Seer can gain an advantage against heroes who rely on evasion as Normal Punch has true strike: Phantom Assassin, Windranger, 
Hoodwink.
Anti-Mage
* Dark Seer's strength lies in his high-mana cost skills. So Mana Break can be a great nuisance for him, since it can reduce his mana and prevent him from casting his spells.
* Mana Void can deal a lot of damage if Dark Seer spent a lot of mana on his abilities.
Phantom Assassin
* Heroes with disables that ignore spell immunity will render Phantom Assassin completely useless in teamfights throughout the game: Axe, Enigma, Vengeful Spirit, Doom, Bane, Beastmaster, Pudge, Medusa, Warlock.
Anti-Mage
* Enigma's Midnight Pulse damage can be substantially mitigated by Anti-Mage's high magic resistance thanks to Counterspell.
* In the early game, Anti-Mage's Mana Void can cancel a 
Black Hole until Enigma gets Black King Bar.
* Should Anti-Mage survive a Black Hole combo, Enigma will have exhausted most of his skills and items, preventing him from defending himself against any counter initiation or a follow-up from a blink escape.
* Anti-Mage's Blink will make him a very hard target to use Black Hole on, having to solo ult him later on in the game or leave him out of the Black Hole.
Phantom Assassin
* Heroes such as 
Lone Druid, 
Tidehunter and Viper can be very problematic for Phantom Assassin because they give her very little time to farm and become scary.
Anti-Mage
* Both 
Gush and 
Ravage do little damage against Counterspell.
* Blink helps Anti-Mage escape through 
Anchor Smash.
* Tidehunter's small mana pool can be eated by Mana Break, preventing to spam his abilities and ignores the protection from 
Kraken Shell.
Additional:
* Mana Break quickly burns Tidehunter's mana pool, preventing him from spamming his abilities, and Kraken Shell does not mitigate the bonus damage component.
* Blink allows Anti-Mage to enter combat quickly and safely after Ravage.
* A well-timed Counterspell can reflect Gush back at Tidehunter.
Phantom Assassin
* Heroes with disables that ignore spell immunity will render Phantom Assassin completely useless in teamfights throughout the game: Axe, Enigma, Vengeful Spirit, Doom, Bane, Beastmaster, Pudge, Medusa, Warlock.
Anti-Mage
* Anti-Mage easily destroys 
Mana Shield with Mana Break, especially once he has Manta Style.
* Anti-Mage effectively avoids 
Stone Gaze with Blink, and can reinitiate after its duration is over.
Additional:
* Mana Break burns Medusa's mana easily, especially when coupled with a Manta Style.
* Can easily initiate on Medusa with Blink, burning her mana or forcing her to use Stone Gaze.
* Mana Void is effective against Medusa's big mana pool and mana usage, presenting a huge hazard to Medusa's allies around her since her Mana Shield still gives her some protection if she has mana.
Anti-Mage
* Heroes with abilities or items that can silence or disable Anti-Mage for long periods of time will prevent him from Blinking away: Lion, Silencer, Shadow Shaman, Grimstroke, Witch Doctor, Riki, Faceless Void, Skywrath Mage, Puck.
Phantom Assassin
* Phantom Assassin doesn't care about Silencer's spells as she relies on right-clicks more than spells.
* Phantom Assassin often builds Black King Bar, which allows her to remove Global Silence before engaging.
Phantom Assassin
* Heroes with disables that ignore spell immunity will render Phantom Assassin completely useless in teamfights throughout the game: Axe, Enigma, Vengeful Spirit, Doom, Bane, Beastmaster, Pudge, Medusa, Warlock.
Anti-Mage
* Past the mid game, an isolated Vengeful Spirit makes for an easy kill for Anti-Mage.
* Magic Missile is the only disable Vengeful Spirit has against Anti-Mage, but he can either Blink away to disjoint the stun or reflect it back against Vengeful Spirit with Counterspell.
* Nether Swap isn't very effective against Anti-Mage - if used offensively, Anti-Mage can simply blink away to safety, and if used defensively, Blink's low cooldown allows him to persistently chase as well.
Phantom Assassin
* Heroes with illusions and summons can be hard for Phantom Assassin to deal with, as she lacks any AoE abilities to deal with them without items: Broodmother, Phantom Lancer, Chaos Knight, Lycan, Naga Siren, Shadow Shaman, Visage, Nature's Prophet, Terrorblade, Warlock, Wraith King.
Anti-Mage
* Mana Break quickly eats away at Wraith King's small mana pool, preventing 
Reincarnation from triggering.
* Wraith King has no innate mobility. Even with 
Blink Dagger, Wraith King is easily kited by Blink.
* Anti-Mage can farm much more quickly than Wraith King, allowing Anti-Mage to overpower Wraith King once a significant farm advantage is established.
Additional:
* Mana Break can prevent Wraith King from reincarnating unless Wraith King has his Aghanim's Shard that removes the mana cost from Reincarnation.
* With Manta Style, his mana burning will triple because illusions can also use Mana Break.
* Wraithfire Blast is quite predictable, and if Anti-Mage can react fast enough, he will be able to disjoint it with Blink or reflect it back with Counterspell.
Phantom Assassin
* Phantom Assassin's Blur is useless against Windranger as she commonly buys items that require 
Javelin like 
Maelstrom, Monkey King Bar or Bloodthorn, and other than Stifling Dagger, Phantom Assassin has nothing else that can bypass Windrun.
* Additionally, Phantom Assassin doesn't like building Monkey King Bar because her crits are reliant on attack damage.
* Focus Fire can still deal considerable damage despite Blur's evasion due to the increased attack speed.
Additional:

* Additionally, Phantom Assassin doesn't like building Monkey King Bar because her crits are reliant on attack damage.
* Focus Fire can still deal considerable damage despite Blur's evasion due to the increased attack speed.
Anti-Mage
* Counterspell can reflects triggering with Focus Fire. Since Focus Fire target against Anti-Mage, Focus Fire damage can return to Anti-Mage easily destroy to Windranger's.
* Anti-Mage items Abyssal Blade and Monkey King Bar can useful for Anti-Mage's and easily complicated escaping Windranger's fighting against Anti-Mage's and also bypasses to Windrun evasion.
Additional:
* Counterspell can reflect Windranger's targeted spells such as 
Shackleshot and 
Focus Fire back to her.
* Blink can be used to avoid Shackleshot and 
Powershot, assuming an Anti-Mage player can react fast enough.
* Mana Break and Mana Void are good against Windranger's high mana pool.
Phantom Assassin
* 
Static Link can lower the damage output from Coup de Grace procs, hindering Phantom Assassin's main source of damage. And Phantom Assassin is not a common 
Linken's Sphere wielder to counter this problem.
* 
Eye of the Storm strikes cannot be evaded by Blur.
* Both Static Link and Eye of the Storm pierces spell immunity, as Phantom Assassin is often reliant on Black King Bar.
Additional:

* Eye of the Storm strikes cannot be evaded by Blur.
* Both Static Link and Eye of the Storm pierces spell immunity, as Phantom Assassin is often reliant on Black King Bar.
Anti-Mage
* Blink can easily break Static Link and Counterspell reflects Static Link on Razor.
Anti-Mage
* Heroes with abilities or items that can silence or disable Anti-Mage for long periods of time will prevent him from Blinking away: Lion, Silencer, Shadow Shaman, Grimstroke, Witch Doctor, Riki, Faceless Void, Skywrath Mage, Puck.
Phantom Assassin
* While Phantom Assassin can kill Skywrath Mage in a few strikes, Skywrath Mage can also do the same to her if she is not careful.
* 
Arcane Bolt's long range and low cooldowns allows Skywrath Mage to severely harass Phantom Assassin in lane.
* 
Ancient Seal prevents Phantom Assassin from escaping or engaging with Phantom Strike.
* 
Mystic Flare's heavy magical damage nukes Phantom Assassin down quickly during the early to mid game.
Additional:
* While Phantom Assassin can kill Skywrath Mage in a few strikes, Skywrath Mage can also do the same to her if she is not careful.
* Arcane Bolt's long range and low cooldowns allows Skywrath Mage to severely harass Phantom Assassin in lane.
* Ancient Seal prevents Phantom Assassin from escaping or engaging with Phantom Strike.
* Mystic Flare's heavy magical damage nukes Phantom Assassin down quickly during the early to mid game.
Anti-Mage
* Mana Break drains Skywrath Mage of his mana, slowing him and dealing bonus damage while rendering him unable to cast his spells.
* Blink makes it incredibly easy for Anti-Mage to close the gap between himself Skywrath Mage to right-click him down. He can also use Blink to get away and escape into fog of war.
* Anti-Mage passively reduces enemy spell damage with Counterspell, and can activate the ability to block and send back Skywrath's Ancient Seal or Arcane Bolt, causing him to silence himself or deal massive damage to himself.
* Skywrath Mage's large mana-costs makes him an easy target for Mana Void.
* Anti-Mage often builds Black King Bar and Manta Style which can dispel Ancient Seal and Concussive Shot.
Phantom Assassin
* Skywrath's pitiful defences also make him easy meat to heroes with high burst like Juggernaut, Lion, or Phantom Assassin, the latter occasionally downing a support Skywrath in a single Stifling Dagger.
Anti-Mage
* Heroes with mobility spells like Queen of Pain, Anti-Mage, Phantom Assassin, Riki, Puck, and Spirit Breaker that are cancelled by Frostbite can suffer greatly from the presence of Crystal Maiden. It is absolutely critical, however, to have followup from teammates, as all of the above heroes can make quick work of the squishy Crystal Maiden after they are released from her grip.
Phantom Assassin
* Though certainly not a "hard counter", Crystal Maiden's skillset (magical damage nukes) does pose a substantial threat to Phantom Assassin through the mid game, especially if followed up with engagement by her team.
* A quick use of Freezing Field directly after Phantom Strike can leave Phantom Assassin trapped inside the area of effect, capitalizing on Phantom Assassin's relatively low HP pool when she is not protected by Blur, and besides Skull Basher, Phantom Assassin hates buying disabling items like 
Scythe of Vyse or 
Eul's Scepter of Divinity.
* If Phantom Assassin chooses not to buy a Black King Bar relatively early, the attack slow from Freezing Field can greatly hinder the proc chance of Coup de Grace in a teamfight.
* However, Phantom Assassin's massive damage, and her tendency to build both Black King Bar and Skull Basher makes her a formidable foe the later the game goes, and fighting her without a team is almost never a good choice.
Anti-Mage
* Heroes with large health pools (Pudge) or good innate magic resistance (Anti-Mage) can be very problematic for Crystal Maiden, since even if they are under the effect of her ultimate for the entire duration, the damage output is simply not enough to kill or force them to retreat.
Phantom Assassin
* Crystal Maiden's low health pool and slow movement speed make her a tempting and easy target.
* However, it may be wise to build Black King Bar first before attempting to fight her alone, as she can disable you and retaliate with 
Freezing Field.
Phantom Assassin
* Heroes who rely on physical damage are easily negated by Ghost Shroud: Phantom Assassin, Wraith King, Juggernaut.
Anti-Mage
* Anti-Mage can withstand magical burst damage much better than other carries, making him effective against nukers: Lich, Necrophos, Oracle, and Leshrac.
Anti-Mage
* Heroes with abilities or items that can silence or disable Anti-Mage for long periods of time will prevent him from Blinking away: Lion, Silencer, Shadow Shaman, Grimstroke, Witch Doctor, Riki, Faceless Void, Skywrath Mage, Puck.
Phantom Assassin
* Fragile support heroes are all ideal targets for the Phantom Assassin. Heroes such as Lina and Witch Doctor are all prime targets that may not be able to react quickly and fight back due to Phantom Assassin's sudden appearance.
Phantom Assassin
* 
Dispersion makes it hard for Phantom Assassin to burst down Spectre while also reflecting back Phantom Assassin's high burst damage against herself.
* Black King Bar is useless for Phantom Assassin against Spectre as all of her skills pierce spell immunity.
* Spectre only needs to be careful against Fan Of Knives from Aghanim's Shard, as it can disable 
Desolate and Dispersion, though this issue can be solved by buying Blade Mail, which is a common item on Spectre.
Additional:
* Dispersion makes it hard for Phantom Assassin to burst down Spectre while also reflecting back Phantom Assassin's high burst damage against herself.
* Black King Bar is useless against Spectre as all of her skills pierce spell immunity.
Anti-Mage
* Spectre cannot chase down Anti-Mage with 
Spectral Dagger because of Blink, though it still grants her team vision over him.
* Counterspell reduces much of the damage from Dispersion and Spectre's 
Radiance.
* Anti-Mage usually builds a Manta Style, preventing Spectre from dealing any Desolate damage to him once he summons his illusions.
Additional:
* Spectre has no way to prevent Blink, for escape or initiation. Anti-Mage can easily pick off enemy supports and Spectre cannot do anything about it.
* Mana Break burns through Spectre's low mana pool.
* Manta Style's illusions prevent Desolate's damage.
* Even though Anti-Mage is outcarried by Spectre in the later stages of the game, a competent Anti-Mage with a Battle Fury can easily outfarm and get ahead of Spectre before she can come online.
Phantom Assassin
* In general, Brewmaster's Cinder Brew and Thunder Clap makes him good against physical damage carries: Ursa, Clinkz, Faceless Void, Troll Warlord, Templar Assassin, Phantom Assassin.
Anti-Mage
* Blinking heroes like Anti-Mage or Queen of Pain can often chase down an injured Brewmaster after his ultimate expires.
Phantom Assassin
* Heroes with heavy early and mid-game magical damage are also problematic for Phantom Assassin due to being able to easily kill her before she can gain an item advantage over them: Lina, Necrophos, Nyx Assassin, Gyrocopter, Jakiro, Death Prophet.
Anti-Mage
* Heroes who build mana boosting items but have low mana regeneration are especially vulnerable against Mana Break and Mana Void: Timbersaw, Slark, Shadow Fiend, Clinkz, Bristleback Nyx Assassin, Magnus
Phantom Assassin
* 
Fire Spirits applies a severe attack speed slow, severely hindering Phantom Assassin's damage output.
* Phantom Assassin cannot cast Phantom Strike on Phoenix during 
Supernova.
Additional:
* While her Phantom Strike does give limited extra attack speed, she cannot use the ability against the Phoenix Sun, and while her Blur may protect her from attacks, Phoenix's strong magical DPS burns away her small health pool quickly, and the attack speed slow makes her unable to fight back (provided she has no source of spell immunity).
Anti-Mage
* Anti-Mage dispels Phoenix's slows with Manta Style.
* Anti-Mage can Blink directly next to Supernova, giving him more time to destroy the egg.
Phantom Assassin
* Morphling's naturally high armor thanks to his high agility makes it hard for Phantom Assassin to take him down with Coup de Grace.
Anti-Mage
* Counterspell's bonus magic resistance causes the Waveform and Adaptive Strike combo to deal significantly less damage.
* Counterspell's active component can reflect the Adaptive Strike back into Morphling, dealing significant damage or even killing him.
* Mana Break combined with Manta Style can quickly burn away Morphling's mana, leaving him unable to use his spells. Black King Bar can no longer be reliably used against Anti mage due to its 50 mana cost.
Phantom Assassin
* Fate's Edict cripples many heroes who rely on attacks, such as Phantom Assassin, Sven, or Enchantress, without a dispel or a Black King Bar.
Anti-Mage
* Anti-Mage can withstand magical burst damage much better than other carries, making him effective against nukers: Lich, Necrophos, Oracle, and Leshrac.
Additional:
* Oracle has minimal damage potential against Anti-Mage due to Counterspell, and may even have some ability damage reflected at himself.
* Anti-Mage can easily overwhelm Oracle with Mana Break and Mana Void.
* Blink allows Anti-Mage to easily chase and take advantage of Oracle's low mobility.
Anti-Mage
*
Fiend's Grip prevents Anti-Mage from Blinking away or using Manta Style. It also pierces spell immunity.
Nightmare sets Bane's team up for chain disables on Anti-Mage.
Enfeeble lowers Anti-Mage's status resistance and magic resistance, making him more vulnerable to disables and magic damage.
*
*
Phantom Assassin
*
Enfeeble greatly reduces Phantom Assassin's attack damage, and if her attack damage is weak, 
Coup De Grace will also suffer from attack damage reduction as well. 
Enfeeble also reduces cast range of Phantom Assassin's abilities, making her unable to harass with 
Stifling Dagger and to use 
Phantom Strike at longer distances.
Nightmare and 
Fiend's Grip can ground Phantom Assassin, who normally blinks around with 
Phantom Strike, and stop her from outputting damage.
Coup De Grace will also suffer from attack damage reduction as well. Enfeeble also reduces any healing Phantom Assassin receives, making her unable to heal herself with Phantom Strike, and it also reduces cast range of Phantom Assassin's abilities, making her unable to harass with
