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.
Underlord
* Glimpse will return Underlord or any of his teammates attempting to escape with Dark Rift if timed correctly.
* Underlord is a slow and low mobility hero, easy to set up Static Storm and 
Kinetic Field, preventing him from using his abilities as well as preventing him using Fiend's Gate to escape.
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.
Underlord
* In general, heroes that provide vision will see Fiend's Gate coming: 
Techies, 
Templar Assassin, 
Treant Protector
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.
Underlord
* X Marks the Spot will return Underlord or his teammate if they escape with Fiend's Gate.
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.
Underlord
* Tanky melee heroes that can easily be kited, which allows Outworld Destroyer to deal heavy damage with Arcane Orb from a distance: 
Sven, 
Underlord, 
Bristleback.
Additional:
* Arcane Orb's pure damage can do great damage to Underlord.
* Sanity's Eclipse can tear down Underlord's health by a large amount, since his mana pool is very low compare to OD's high mana pool.
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
Underlord
* Io can escape from Pit of Malice with Tether or Relocate.
* Relocate can counter Dark Rift's split pushing.
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.
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.
Underlord
* Heroes that depend on disrupting fights with ability combos or big ultimate abilities are vulnerable to the long stun of Fiend's Grip: 
Disruptor, 
Death Prophet, 
Enigma, 
Faceless Void, 
Invoker, 
Lich, 
Magnus, 
Mars, 
Medusa, 
Outworld Destroyer, 
Phoenix, 
Puck, 
Queen of Pain, 
Shadow Fiend, Treant Protector, Underlord, 
Winter Wyvern, 
Witch Doctor, 
Zeus.
Underlord
* In general, attacks of the melee heroes who are entirely reliant on dealing physical damage and/or have very little to no area-of-effect abilities will make Underlord tickle and will have no effect against him, and will be unable to ambush Underlord and his team if Underlord chooses to use 
Fiend's GAte to get to a designated point of the map: 
Phantom Assassin, 
Terrorblade, 
Troll Warlord, 
Drow Ranger, 
Phantom Lancer, 
Chaos Knight, Sven, 
Wraith King, 
Bounty Hunter, 
Alchemist, Templar Assassin, 
Nyx Assassin, 
Bane.
Underlord
* 
Winter's Curse and 
Splinter Blast can devastate Underlord's team when they're grouped up for Dark Rift.
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.
Underlord
* 
Fury Swipes damage is not reduced by Atrophy Aura, essentially bypassing Underlord's only natural defense.
* 
Enrage can quickly dispel the root of Pit of Malice.
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.
Underlord
* 
Firestorm will do little percentage damage to a small HP hero like Monkey King.
* All aspects of Jingu Mastery benefits ignore 
Atrophy Aura's base damage reduction.
* Monkey King can get on top of Underlord easily at any stage of the game.
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.
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.
* Be careful when using Doom as a well-timed Counterspell can block and reflect it back against Doom himself.
* An Aghanim's Scepter upgraded Doom will also disable 
Mana Break and Counterspell, which makes Anti-Mage significantly less effective in fights and more susceptible to the high magical damage of Doom's abilities and his allies.
Underlord
* 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.
Additional:
* 
Infernal Blade does damage based on percentage health, and is useful against high health pool hero like Underlord.
* Doom can prevent Underlord from spamming his abilities and most important is to prevent him from using Fiend's Gate to escape.
Underlord
* In general, melee heroes without blink mechanisms or spell immunity will have a hard time positioning against Pit of Malice: Sven, 
Tiny, Wraith King, 
Dragon Knight, 
Meepo, 
Doom, Bounty Hunter, 
Dark Seer, 
Undying, Alchemist, 
Legion Commander.
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.
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.
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.
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
* A well-timed use of The Swarm provides vision over heroes with high mobility: Anti-Mage, 
Arc Warden, Dark Seer.
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.
Underlord
* Durable heroes relied a lot on their main passive effects and items' effects such as Bristleback, Underlord, 
Spectre and Dragon Knight can be disabled easily with 
Sharpshooter's break, reducing their potential in teamfights.
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.
Underlord
* In general, heroes that provide vision will see Fiend's Gate coming: Techies, Templar Assassin, Treant Protector
Underlord
* Firestorm will destroy Refraction charges very quickly.
* Firestorm will hit Templar Assassin while under the effects of Meld Meld.
* Templar Assassin has a hard time maneuvering around Pit of Malice.
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.
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 protects against Mana Break.
* 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.
Underlord
* Strong laners are usually at a disadvantage because of how well Sven can jungle. Heroes such as Dark Seer. Underlord and Legion Commander may find that later Sven takes care of them very quickly after some jungle farming.
Underlord
* In general, attacks of the melee heroes who are entirely reliant on dealing physical damage and/or have very little to no area-of-effect abilities will make Underlord tickle and will have no effect against him, and will be unable to ambush Underlord and his team if Underlord chooses to use Fiend's GAte to get to a designated point of the map: Phantom Assassin, Terrorblade, Troll Warlord, Drow Ranger, Phantom Lancer, Chaos Knight, Sven, Wraith King, Bounty Hunter, Alchemist, Templar Assassin, Nyx Assassin, Bane.
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.
Underlord
* In general, melee heroes without blink mechanisms or spell immunity will have a hard time positioning against Pit of Malice: Sven, Tiny, Wraith King, Dragon Knight, Meepo, Doom, Bounty Hunter, Dark Seer, Undying, Alchemist, Legion Commander.
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.
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
Underlord
* 
Reaper's Scythe and 
Heartstopper Aura deal percentage-based damage, ignoring Underlord's high health.
* 
Ghost Shroud protects Necrophos from Underlord's damage from Atrophy Aura, and also amplifies all the healing Necrophos receives.
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
* 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
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.
Anti-Mage
* Heroes that can drain mana negatively affect Viper's ability to use Poison Attack, Nethertoxin and Viper Strike: Lion, Anti-Mage
Underlord
* Shadow Fiend can still dish out heavy damage with 
Requiem of Souls and 
Shadowraze while caught in Pit of Malice.
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
* 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.

Underlord
* 
Dark Rift allows Underlord to transport allies from poison damage-over-time to the fountain.
* Underlord usually buys 
Pipe of Insight that gives a magic resistance to allies, inhibiting the damage from Venomancer abilities.
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.
Underlord
* Underlord's Atrophy Aura reduces Morphling's high base damage gained through agility shift.
Anti-Mage
* Counterspell can helpful blocked off to 
Dragon Tail.
Additional:
* Counterspell makes Dragon Tail useless from Dragon Knight. Because stunned with Dragon Tail, Counterspell from Anti-Mage activate makes strong blocked reflected and Dragon Tail 's throw affect stunned return to Dragon Knight.

Underlord
* In general, heroes with long cooldowns on their abilities or ultimate will struggle against the relentless pressure provided by Dark Rift or Fiend's Gate (Requires Aghanim's Scepter): Terrorblade, Dragon Knight, 
Omniknight.
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.
Underlord
* In general, melee heroes without blink mechanisms or spell immunity will have a hard time positioning against Pit of Malice: Sven, Tiny, Wraith King, Dragon Knight, Meepo, Doom, Bounty Hunter, Dark Seer, Undying, Alchemist, Legion Commander.

Underlord
* Heroes that reduce the damage that Marci can deal during her ultimate, like 
Razor, 
Rubick, Bane, Dragon Knight and Underlord.
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.
Underlord
* Firestorm makes quick work of Treants and Atrophy Aura gives him temporary damage for every Treant killed.
* 
Pit of Malice can stop Teleportation channeling.
* Atrophy Aura greatly reduces Nature's Prophet's damage and he has no other good way to deal damage.
* Fiend's Gate can counter split-pushing, which is something that Nature's Prophet relies on a lot. Fiend's Gate can also be used to either escape from Nature's Prophet or to prepare an ambush on Nature's Prophet, and outside from Nature's Wrath, Nature's Prophet has no other ways to intercept arrivals with Fiend's Gate.
Anti-Mage

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.
Underlord
* In general, attacks of the melee heroes who are entirely reliant on dealing physical damage and/or have very little to no area-of-effect abilities will make Underlord tickle and will have no effect against him, and will be unable to ambush Underlord and his team if Underlord chooses to use Fiend's GAte to get to a designated point of the map: Phantom Assassin, Terrorblade, Troll Warlord, Drow Ranger, Phantom Lancer, Chaos Knight, Sven, Wraith King, Bounty Hunter, Alchemist, Templar Assassin, Nyx Assassin, Bane.
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.

* In general, attacks of the melee heroes who are entirely reliant on dealing physical damage and/or have very little to no area-of-effect abilities will make Underlord tickle and will have no effect against him, and will be unable to ambush Underlord and his team if Underlord chooses to use Fiend's GAte to get to a designated point of the map: Phantom Assassin, Terrorblade, Troll Warlord, Drow Ranger, Phantom Lancer, Chaos Knight, Sven, Wraith King, Bounty Hunter, Alchemist, Templar Assassin, Nyx Assassin, Bane.
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.
Underlord
* Heroes with powerful rooting abilities will disable most of Pangolier's skills, a bonus point if it pierces spell immunity since it will also be able to stop Pangolier during his Rolling Thunder: Treant Protector, Meepo,

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
* 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.

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.
Anti-Mage
* If Meat Hook is used before Blink, Anti-Mage may be able to escape Pudge's grasp by blinking to safety.

* Pit of Malice is very good at preventing Primal Beast from entering the fight and stopping Trample damage at all stages of the game.
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
* 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.
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.
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.
Anti-Mage
* 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.
Additional:
* 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.
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.
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
* 
Echo Stomp and 
Earth Splitter's long cast times give Anti-Mage plenty of time to Blink away.
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.
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.
Underlord
* Firestorm will easily clear Chen's creeps.
* Pit of Malice will trap Chen and render him helpless.
* Atrophy Aura gives bonus damage to Underlord for each killed creep and weakens Chen's damage output.
* Fiend's Gate can counter Chen's pushing attempts, and he has nothing to intercept it.
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 Invoker as it could put him in a bad position, while Arc Warden summons his doubles and rain damage into him.
Underlord
* Firestorm's percentage damage can quickly demolish the Spirit Bear's high HP
* Pit of Malice will allow allies to easily kite Lone Druid due to his low mobility
Anti-Mage
* Heroes that can jump on her: Slark, Queen of Pain, Anti-Mage
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
Underlord
* In general, melee heroes without blink mechanisms or spell immunity will have a hard time positioning against Pit of Malice: Sven, Tiny, Wraith King, Dragon Knight, Meepo, Doom, Bounty Hunter, Dark Seer, Undying, Alchemist, Legion Commander.
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
* 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.
Underlord
* In general, heroes with spell immunity abilities won't be caught inside by Pit of Malice: 
Juggernaut, 
Lifestealer.
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.
Underlord
* Heroes with abilities that can save teammates are also effective such as 
Shadow Demon, 
Dazzle, Oracle, Bane, 
Pugna, 
Tusk, Winter Wyvern, 
Io, Underlord, Treant Protector and 
Keeper of the Light.
Underlord
* In general, attacks of the melee heroes who are entirely reliant on dealing physical damage and/or have very little to no area-of-effect abilities will make Underlord tickle and will have no effect against him, and will be unable to ambush Underlord and his team if Underlord chooses to use Fiend's GAte to get to a designated point of the map: Phantom Assassin, Terrorblade, Troll Warlord, Drow Ranger, Phantom Lancer, Chaos Knight, Sven, Wraith King, Bounty Hunter, Alchemist, Templar Assassin, Nyx Assassin, Bane.
Anti-Mage
* Blinking heroes like Anti-Mage or Queen of Pain can often chase down an injured Brewmaster after his ultimate expires.
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.
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.
Underlord
* Heroes with AoE nukes will clear her illusions in no time, especially if they are percentage-damage-based, like Underlord's Firestorm, 
Elder Titan's Earth Splitter, Enigma's 
Midnight Pulse, Zeus's 
Arc Lightning, 
Jakiro's 
Liquid Frost from Aghanim's Shard etc.
Underlord
* Heroes that require burst damage to kill will be difficult for Phantom Lancer to take down: Timbersaw, 
Axe, Bristleback, Alchemist and Underlord
Additional:
* Firestorm is very useful for clearing multiple illusions swiftly.
* Pit of Malice will continuously disrupt many illusions, drastically reducing their damage and potency.
* Athropy Aura reduces damage of both Phantom Lancer and his illusions.
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
* 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
* 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.
Underlord
* Atrophy Aura reduces Terrorblade's damage significantly, even during Metamorphosis.
* Firestorm deals significant damage to Terrorblade and his illusions from a safe distance.
* Pit of Malice can keep Terrorblade and his illusions under control.
* Fiend's Gate can either bail out Underlord's team away from a bad engagement against a Terrorblade under Metamorphosis or caught Terrorblade off guard if he is not careful, and besides Reflection, Terrorblade has no other abilities to intercept Underlord nor his team when they use it to start a teamfight.
* Likewise, Fiend's Gate can be used to quickly move Underlord's team to the frontlines, to strike Terrorblade and his allies during Metamorphosis's 150 seconds of cooldown.
Additional:
* Firestorm deals significant damage to Terrorblade and his illusions from a safe distance.
* Pit of Malice can keep Terrorblade and his illusions under control.
* Atrophy Aura reduces Terrorblade's damage significantly, even during Metamorphosis.
* Fiend's Gate can either bail out Underlord's team away from a bad engagement against a Terrorblade under Metamorphosis or caught Terrorblade off guard if he is not careful, and besides Reflection, Terrorblade has no other abilities to intercept Underlord nor his team when they use it to start a teamfight. Likewise, Fiend's Gate can be used to quickly move Underlord's team to the frontlines, to strike Terrorblade and his allies during Metamorphosis's 150 seconds of cooldown, forcing Terrorblade to buy Aghanim's Scepter that will give him access to 
Terror Wave ability.
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.
Underlord
* Firestorm and Pit of Malice are very disruptive in team fights, completely matching Mars especially since it can all be cast inside Arena Of Blood and also does percentage-based magical damage, negating Bulwark.
* Dark Rift can save any allies of Underlord trapped in Arena Of Blood.
* Atrophy Aura allows Underlord to lane against Mars quite well since he does not have the best base damage during the early game.
* Underlord is a common carrier of both Pipe of Insight and 
Mekansm/
Guardian Greaves, allowing his team to combat Mars in the mid to late game.
Underlord
* In general, heroes that provide vision will see Fiend's Gate coming: Techies, Templar Assassin, Treant Protector
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.
Underlord
* Heroes with long cast animations can be continuously interrupted by Battery Assault: 
Centaur Warrunner, Jakiro, Leshrac, Naga Siren, Underlord.
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.
Underlord
* Melee heroes who may struggle to get close to Sniper: Wraith King, Kunkka, Doom, 
Tidehunter, Underlord, Troll Warlord, and etc.
Additional:
* Sniper's very long range allows him to stay out of Firestorm and Pit of Malice as well as Atrophy Aura range.
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.
* Counterspell active is even more dangerous if Anti-Mage purchased Aghanim's Scepter. Aghanims scepter allows antimage to bait out snipers range tools like pike or flashbang. Otherwise the illusion will drain his mana
* 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 mean to disengage.
* Anti-Mage has faster farming speed. He can outfarm and get ahead of sniper easily.
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
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
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.
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.
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
* 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.
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.
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.
Underlord
* Pit of Malice prevents Riki from casting 
Blink Strike. or 
Tricks of the Trade.
* Atrophy Aura reduces Riki's damage.
* Firestorm can be used to harrass Riki in lane.
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.
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
Underlord
* Heroes with AoE abilities will hit Slark in Shadow Dance: 
Lina, Jakiro, Underlord, Leshrac, Dark Seer, 
Earthshaker, Timbersaw, Crystal Maiden.
Underlord
* As a frontline tank, the abilities of Underlord is surprisingly spell-cast heavy, and is often great for Rubick to steal.
* Firestorm is a great ability for farming, pushing and serves as a useful teamfight damage source, and even more so when its damage is amplified by 
Arcane Supremacy and Aghanim's Shard.
* It is worth mention that Firestorm has no visible effect on heroes other than damage, and the enemy team may easily mistaken the ability as casted by Underlord, resulting in unexpectedly soaking up more damage.
* Pit of Malice is a great area control ability in teamfights, capable of trapping multiple heroes in a hazard area.
* Underlord has no immediate reposition ability, and since he usually stays at the front, he can be an easy target for Rubick's Pit of Malice.
* Fiend's Gate, if stolen, grants Rubick's team great versatility around the map. Creating a surprise gank or appear as a group at the enemy backline during skirmish, escaping as a team from bad situations, or even taking Roshan or enemy highground unexpectedly, the possibility are endless with careful communication among Rubick's team.
Additional:
* All of Underlord's abilities are useful for Rubick to 
Spell Steal.
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.
Anti-Mage
* Anti-Mage's low health pool making vulnerable to Phantom Assassin's burst damage and 
Coup De Grace critical strike, while Blink is on cooldown.
* 
Blur makes Anti-Mage unable to deal Mana Break to her.
* Phantom Assassin has low intelligence and low mana pool, making Mana Void do minimal damage.
Additional:
* Anti-Mage can easily withstand heavy magical bursts due to Counterspell, but he is still somewhat vulnerable to physical damage. Phantom Assassin's burst physical damage can destroy Anti-Mage while Blink is on cooldown or while he is stunned or hexed.
* Blur makes Anti-Mage unable to deal significant damage to her without buying Monkey King Bar, which means he cannot buy items to benefit his Mana Break.
* Phantom Assassin has an abysmal mana pool and intelligence gain, making Mana Break and Mana Void deal minimal damage.
Underlord
* 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:
* 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 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.
Underlord
* 
Static Link greatly reduces Underlord damage, while benefits Razor himself, even when in Atrophy Aura's range.
* Underlord is a slow and low mobility hero, and cannot outrun Razor's high movement speed, easily for Razor to absorb his damage with Static Link to the maximum and burst him down from the bonus damages, combine with the armor reduction from 
Eye of the Storm .
Anti-Mage
* Blink can easily break Static Link and Counterspell reflects Static Link on Razor.
Underlord
* Enigma's Midnight Pulse damage can make Underlord suffer heavy damage due to his high health.
* Enigma can catch Underlord and his team off guard with Midnight Pulse and 
Black Hole when they teleport using Fiend's Gate. And Atrophy Aura offers no defense against them.
* However, Enigma needs to approach Underlord carefully as Underlord can interrupt channeling of the Black Hole with Pit of Malice and can also use Firestorm to scout Enigma's location which can also put Enigma's Blink Dagger on cooldown if Enigma has no Black King Bar available to use.
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.
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.
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.
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.
Underlord
* Atrophy Aura reduces Drow Ranger's damage significantly, as she relies on agility to be effective.
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.
Underlord
* Atrophy Aura's percentage-based damage reduction greatly diminishes Legion Commander's overall damage output, even if she has won many Duels
* Legion Commander cannot get out the way of Firestorm because she is stationary.
Additional:
* Atrophy Aura makes it hard for Legion Commander to win Duels.
* Fiend's Gate can be used to save Underlord and his allies from a Duel or to intercept Legion Commander, because outside from 
Overwhelming Odds, Legion Commander has no other area-of-effect abilities.
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.
Underlord
* Damage reduction from Atrophy Aura prevents Bloodseeker from killing targets and gaining his Thirst bonuses.
* Pit of Malice's area of effect catches Bloodseeker easily, negating his speed bonus during teamfights.
* Dark Rift allows Underlord to transport Ruptured allies to the fountain, rendering it useless.
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.
Underlord
* Pit of Malice can be cast in the path of Spirit Breaker's Charge of Darkness to cancel it.
* Fiend's Gate provides a way to escape from a gank for Underlord and his teammates. Likewise, Fiend's Gate can be used to ambush Spirit Breaker who has little to no ways of intercepting Underlod and his teammates when they use it to move around the map.
Underlord
* In general, heroes with spell immunity abilities won't be caught inside by Pit of Malice: Juggernaut, Lifestealer.
Anti-Mage
* Heroes with escape abilities : Anti-Mage Dark Seer Slark Storm Spirit 
Windranger Weaver can kite Lifestealer due to him having no lockdown
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.
Underlord
* Atrophy Aura decreases Troll Warlord's damage.
* Pit of Malice helps lock down Troll Warlord.
* Battle Trance disallows Troll from running out of both Firestorm and Pit of Malice.
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.
Anti-Mage
* As a caster, Anti-Mage's Mana Break and Mana Void are highly effective against him.
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.

* 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.

Eclipse can be devastating for Underlord's team when they're grouped up for Fiend's Gate, it can also be used to intercept arrivals with Fiend's Gate. And Pit of Malice does not prevent Luna to use it.
Aghanim's Scepter upgraded 
Eclipse can finish off Underlord or any of his teammates escape attempts with Fiend's Gate if timed correctly.
