Kunkka
* 
Supernova negates Kunkka's combo entirely, as it can't be affected by spells while using Supernova.
* 
Icarus Dive also allows Phoenix to dodge Ghostship and Torrent.
Shadow Demon
* Icarus Dive quickly escapes from Shadow Demon abilities, especially 
Demonic Purge.
* Phoenix AoE abilities remove Shadow Demon's illusions created by 
Disruption.
Shadow Demon
* Shadow Demon's Demonic Purge with 
Aghanim's Scepter cannot break 
Reincarnation, which could put him in a disadvantage against Wraith King if his whole team is with him.
* 
Vampiric Spirit can out-heal the damage from Shadow Demon's abilities.
* However, Wraith King is a single-target hero, so he cannot deal with Disruption illusions.
Shadow Demon
* Diabolic Edict and Pulse Nova will tear apart any illusions spawned from Disruption
* Split Earth can punish improper usage of Disruption.
* Leshrac does not have any buffs that can be removed by Demonic Purge.
Additional:
* 
Pulse Nova makes quick work of any illusions with amplified damage, and deals damage even if Leshrac is in Disruption.
* An attempt to save an ally using Disruption can easily become a perfect setup for a 
Split Earth for the enemy.
* Disruption does not stop 
Diabolic Edict and Pulse Nova once they start pulsing, and even worse it provides a safe shelter for Leshrac to keep pumping up his powerful AoE damage onto the battlefield.
* Shadow Demon doesn't have the burst damage to take Leshrac out of the fight quickly, although Demonic Purge can help his allies kill a squishy Leshrac.
Shadow Demon
* 
Dragon Slave will make quick work of the spawned illusions from Disruption.
* An attempt to save an ally using Disruption can easily become a perfect setup for a 
Light Strike Array for the enemy.
* Shadow Demon doesn't have the burst damage to take Lina out of the fight quickly, although Demonic Purge can help his allies kill a squishy Lina.
Shadow Demon
* All of Pugna's abilities are active, making Demonic Purge break from Aghanim's Scepter useless.
* 
Nether Ward punishes Shadow Demon's constant mana usage from spamming spells, especially Shadow Poison.
* An attempt to save an ally using Disruption can easily become a perfect setup for a 
Nether Blast for the enemy.
* 
Life Drain can be used to heal Pugna or an ally to save them from Shadow Demon's abilities.
* However, it can be cancelled by Disruption unless Pugna buys defensive items.
Kunkka
* Clinkz's high damage output and insane attack speed late-game can take Kunkka out of the fight before it begins.
* 
Burning Barrage and 
Searing Arrows together can kill allies easily even under Ghostship's buff.
* 
Skeleton Walk can allow Clinkz to make a quick escape after Kunkka's combo, or even avoid it all together.
Kunkka
* Timbersaw Defeats Kunkka on the center line, due to the fact that he has a huge resistance to physical damage by 
Reactive Armor, which is why 
Tidebringer almost does not break through Timbersaw, and due to 
Whirling Death Timbersaw can very much break through Kunkka and force him to leave the line, or spend money on 
Tango.
Additional:
* Timbersaw easily beats Kunkka on the midlane, due to the fact that he has huge physical damage resistance from Reactive Armor, which is why Tidebringer almost does not break through Timbersaw, and due to Whirling Death and Kunkka being a strength hero, Timbersaw can very much break through Kunkka and force him to leave the lane, or spend money on Tango.
Kunkka
* Rubick can steal abilities from Kunkka (except Tidebringer) with 
Spell Steal. Since build Aghanim's Scepter, Rubick's make two steal abilities from Kunkka when the spot is right.
Additional:
* 
Kunkka is a strong teamfighter with his powerful control spells, which Rubick could exploit to his advantage.
* 
Torrent provides another source of damage and crowd control.
* 
Ghostship is a powerful teamfight spell, providing huge magical damage to enemies and buffing allies with damage negation.
* Both skills works the best when comboed with other source of control from allies, such as 
Duel or 
Beserker's Call.
* 
Telekinesis can reposition an enemy onto a Torrent or Ghostship.
* 
Torrent Storm works as a disruptive spell for Rubick to create chaos around him.
* 
Tidal Wave offers another source of control and repositioning.
* As long as Kunkka gains these spells with 
Aghanim's Shard and Aghanim's Scepter, 
Rubick does not need extra items to steal these spells.
* 
X Marks the Spot serves as a utility spell for escaping, chasing and other useful functions.
Shadow Demon
* 
Chaos Knight, 
Lone Druid, 
Meepo and 
Arc Warden can be hard targets since Shadow Demon's spells are ill-suited to fight many enemies at once.
Kunkka
* Melee heroes with low mobility can be kited and killed by Viper: 
Treant Protector, Kunkka, 
Alchemist, 
Troll Warlord, 
Wraith King, 
Tiny, 
Sven.
Kunkka
* Treant Protector's 
Living Armor will also negate Tidebringer's damage.
Shadow Demon
* You can potentially kill a fragile 
Weaver by using Disruption during 
Shukuchi with a well-placed 
Sentry Ward, wasting the Shukuchi. But odds are he'll wait to get low health, 
Time Lapse the damage away and Shukuchi away once more.
Kunkka
* 
Rage negates Kunkka's X Marks the Spot.
* As a strength hero with high strength gain and very little armor, as well as low agility gain, Kunkka is vulnerable to Lifestealer's 
Feast and 
Open Wounds.
Shadow Demon
* Melee carries such as Sven, 
Ursa or 
Lifestealer can be slowed and easily kited with Demonic Purge.
Kunkka
* 
Blade Fury negates Kunkka's X Marks the Spot.
* Kunkka has no way to dodge 
Omnislash.
* Kunkka has no way to hit 
Healing Ward directly in battle, and it mitigates Ghostship and Tidebringer's damage.
Shadow Demon
* 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.
Additional:
* Be ready to save an ally from Omnislash with your Disruption.
* Spawning 
Juggernaut's illusions is a great deal, as his base attack time is low and he has a critical strike. Illusions will benefit from both.
* Demonic Purge will prevent Juggernaut's desperate attempt to flee using Blade Fury. However, it cannot stop him if he is using 
Town Portal Scroll.
Kunkka
* 
Guardian Angel makes allies immune to all physical damage, effectively causing Tidebringer to do no damage.
* 
Purification is a powerful, pure damaging heal that can save Omniknight's allies after Kunkka's large damage.
Shadow Demon
* Heroes that can purge buffs can dispel Guardian Angel: 
Invoker, Shadow Demon, Oracle.
Additional:
* Demonic Purge can dispel Guardian Angel on the key target during combat, allow your allies to finish them.
Kunkka
* Ursa's massive physical damage can destroy Kunkka quickly.
* 
Enrage can be activated before being hit by Ghostship to prevent most of the damage.
* 
Earthshock slows Kunkka's movement speed. With no escape abilities, Kunkka is easy prey.
Shadow Demon
* Melee carries such as Sven, Ursa or Lifestealer can be slowed and easily kited with Demonic Purge.
Additional:
* Shadow Demon's Demonic Purge renders Ursa useless even through 
Black King Bar as it slows him, continually purges his Overpower charges and can not be dispelled by Ursa's Enrage.
* Disruption is a good way to save teammates against Ursa. Disrupting Ursa is also a good way to kite him, as it can not be dispelled by Enrage.
Shadow Demon
* All of Lion's abilities are active making Demonic Purge break from Aghanim's Scepter useless.
* 
Hex and 
Mana Drain can make quick work of whatever illusions you're creating, especially when he acquires his Talents at level 20 and 25.
* An attempt to save an ally using Disruption can easily become a perfect setup for a 
Earth Spike or 
Finger of Death with Aghanim's Scepter for the enemy.
Kunkka
* Lion lacks mobility or escape mechanisms, making him an easy target for abilities like 
Mirana's 
Sacred Arrow or 
Leshrac's Split Earth, or combos like Kunkka's X Marks the Spot into Torrent.
Shadow Demon
* Shadow Demon will have a hard time catching Storm Spirit, as he can get away with 
Ball Lightning.
* 
Static Remnant will make quick work of the spawned illusions from Disruption.
* With very high mobility and usually being paired with 
Orchid Malevolence, he can catch Shadow Demon with ease both in ganks and in teamfights if Shadow Demon has no survivability items.
Kunkka
* In general, highly mobile heroes like 
Earth Spirit or 
Storm Spirit are at a disadvantage against X Marks the Spot.
* Similarly, heroes with low cooldown teleports can be afraid to split push against X Marks the Spot, such as 
Tinker and 
Nature's Prophet.
Shadow Demon
* 
Death Ward with Aghanim's Scepter makes quick work of the spawned illusions from Disruption.
* However, it can be cancelled by Disruption until Witch Doctor buys 
Linken's Sphere or Black King Bar.
* All of Witch Doctor's abilities are active, making Demonic Purge break from Aghanim's Scepter useless.
* 
Voodoo Restoration can out-heal the damage from Shadow Demon's abilities.
* An attempt to save an ally using Disruption can easily become a perfect setup for a 
Maledict or 
Paralyzing Cask for the enemy.
Kunkka
* Heroes with long channeling abilities like 
Witch Doctor are easy targets for Kunkka to interrupt in team fights.
Additional:
* Torrent can cancel Death Ward from a far distance.
Shadow Demon
* All of Puck's abilities are active making Demonic Purge break from Aghanim's Scepter useless.
* Shadow Demon will find a hard time catching a Puck, as he can get away with 
Illusory Orb or even 
Waning Rift;
* Puck can dodge Shadow Poison waves and potentially avoid the damage from Demonic Purge with 
Phase Shift. Furthermore, after Disruption ended, Puck can use Phase Shift to avoid any further danger and can blink away with 
Blink Dagger.
* Waning Rift can be used to initiate Shadow Demon, prevent him from using any spells.
Kunkka
* Heroes who are strong against mobile heroes: 
Disruptor, 
Bloodseeker, Kunkka, Keeper of the Light.
Kunkka
* With his 
Take Aim, Sniper can simply sit out of your ability range and deal massive damage if not killed first.
* 
Assassinate can target allies who are still alive with low health because of Ghostship's buff.
* 
Headshot makes it harder for Kunkka to position/escape and makes it hard for Kunkka to hit with Tidebringer.
Shadow Demon
* Heroes with high physical damage output but lack of reliable escape mechanisms are always a good target for a solo gank: 
Sniper, 
Shadow Fiend, Troll Warlord, 
Drow Ranger. Those heroes, however, are dangerous if they manage to close the gap, so take caution.
Kunkka
* 
Leap allows Mirana to easily escape Torrent and Ghostship.
Shadow Demon
* Heroes with summons or illusions makes Sacred Arrow harder to land: Shadow Demon, 
Phantom Lancer, Nature's Prophet.
Kunkka
* Windranger can't escape 
Windrun X Marks the Spot with combo Torrent or Ghostship trap.
Shadow Demon
* Shadow Demon can waste precious seconds of Windrun with Disruption.
* Alternatively, Demonic Purge can be used to dispel it altogether, leaving her completely defenseless for 7 seconds.
* Disruption can be used to save an ally if they get stunned by 
Shackleshot.
Additional:
* Shadow Demon can waste precious seconds of Windrun with Disruption.
* Alternatively, Demonic Purge. can be used to dispel it altogether, leaving her completely defenseless.
* Disruption can be used to save an ally if they get stunned by Shackleshot.
Kunkka
* Ghostship can stun Faceless Void and give damage reduction to allies that are trapped during Chronosphere.
* Torrent can stun Faceless Void from outside Chronosphere.
* X Marks the Spot can bring back Faceless Void if he escapes using Time Walk.
* If the timing is right and there are allies to attack, a combination of X Marks the Spot, Ghostship, Torrent and Tidebringer can kill Faceless Void instantly.
Shadow Demon
* Disruption can banish Faceless Void or an ally in Chronosphere, making it a less effective ability.
* Faceless Void's illusions created by Disruption will not get stunned by Chronosphere, allowing Shadow Demon to attack Faceless Void in his Chronosphere.
* Casting Disruption after releasing 
Shadow Poison charges will make Time Walk unable to backtrack the damage.
* Shadow Poison is a good way to deal damage as the initial damage and the release damage can't both be Time Walked at the same time.
* Demonic Purge is a great slow, useful to force out a Time Walk early and can break Time Lock with Aghanim's Scepter.
Kunkka
* Tidebringer will deal lots of damage to Alchemist before he builds physical survivability items.
* Torrent and X Marks the Spot can control Alchemist at all stages of the game before he has Black King Bar.
* Ghostship's rum buff will greatly reduce the Alchemist's damage output in teamfights including his Radiance.
Shadow Demon
* Alchemist is a well-known 
Radiance carrier among other auras your illusions will benefit from. They also get the extra move speed and reduced base attack time from his 
Chemical Rage, and it's even better if you can catch him as his own rage is about to expire.
* Disruption will buy enough time for all allies to retreat when Alchemist starts to activate 
Unstable Concoction.
Kunkka
* X Marks the Spot prevents Dark Seer or his allies from escaping with Surge.
Shadow Demon
* The constant dispel from Demonic Purge will make any attempt to save the victim or himself by 
Surge become futile. For what it's worth, Demonic Purge will also dispel 
Ion Shell.
Kunkka
* Spectre can't escape with 
Spectral Dagger under X Marks the Spot.
* Kunkka can dominate Spectre's lane using Tidebringer and gain an advantage.
* Ghostship helps your team soak up damage from 
Haunt.
Shadow Demon
* Her illusions with 
Desolate are very valuable, especially when they are usually paired with Radiance. Unlike blink or force movement, Spectral Dagger's escaping mechanic requires manual movement, and therefore Demonic Purge can hold her back really hard and allow your allies to finish her off.
* If she tries to kill you or any key ally with Haunt at any point of the game, remember to not panic and always use Disruption on the illusion, whether it is fake or the real Spectre herself. When the situation calls, Demonic Purge can save a second victim from a haunting Spectre.
* When upgraded by Aghanim's Scepter, Demonic Purge can remove Spectre from a fight by disabling Desolate and 
Dispersion, negating her damage and tankiness respectively.
Kunkka
* Kunkka can bring Anti-Mage back with X Marks the Spot, effectively negating Blink or forcing him to wait out the debuff before Blinking.
Shadow Demon
* 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.
Kunkka
* Kunkka's Ghostship and Torrent disrupt fights in Arena Of Blood.
Shadow Demon
* Heroes with break abilities: Shadow Demon (with Aghanim's Scepter), 
Viper.
Kunkka
* Similarly, heroes with low cooldown teleports can be afraid to split push against X Marks the Spot, such as Tinker and Nature's Prophet.
* In general, highly mobile heroes like Earth Spirit or Storm Spirit are at a disadvantage against X Marks the Spot.
* Similarly, heroes with low cooldown teleports can be afraid to split push against X Marks the Spot, such as Tinker and Nature's Prophet.
Additional:
* X Marks the Spot can be used to prevent Tinker from escape with Blink Dagger or 
Keen Conveyance, discourage him from snapping farm and snapping gank. However, in later game, it'll be much more difficult because Tinker can buy Black King Bar or Linken's Sphere to prevent Kunkka from placing X on him, or 
Eul's Scepter of Divinity to prevent the recall.
Shadow Demon
* Heroes that can gain vision over trees to catch Tinker: Invoker, Shadow Demon, 
Batrider.
Kunkka
* Heroes that punish mobile heroes: Bloodseeker, Keeper of the Light, Kunkka, Disruptor.
Shadow Demon
* Heroes with ways to protect themselves or allies from Spirit Breaker's initiation: Shadow Demon, 
Outworld Destroyer, 
Omniknight, 
Dawnbreaker.
Shadow Demon
* For the same reason, he has to be slightly more cunning when playing against heroes that can scout the treeline, such as 
Ancient Apparition and his 
Ice Vortex and Shadow Demon and his Shadow Poison.
Kunkka
* X Marks the Spot breaks Flaming Lasso when used on ally and can break if used on Batrider.
Shadow Demon
* Shadow Demon, Outworld Destroyer and Tusk can all save a Lasso'd teammate with their defensive spells.
Shadow Demon
* Shadow Demon's spammable illusions can be used to scout Techies' 
Proximity Mines.
Shadow Demon
* Although Phantom Lancer will generate strong illusions, and you can also break his 
Juxtapose with an Aghanim's Demonic Purge, you have a small chance of guessing which is the real Phantom Lancer after he uses 
Doppelganger.
Kunkka
* Tidebringer, Torrent and Ghostship destroys Phantom Lancer's illusion army.
* Phantom Lancer can't escape with Doppelganger under your X Marks the Spot, but can use it to dodge it.
Additional:
* Tidebringer and Kunkka's AoE abilities in general are effective in clearing Phantom Lancer's illusions.
Shadow Demon
* Shadow Demon's Demonic Purge is undispellable.
* Heroes with undispellable debuffs will help identify the real Phantom Lancer through visual effects or debuff indicators, provided that it was cast on the real Phantom Lancer to begin with:
* 
Doom's 
Doom marks Phantom Lancer with a highly visible effect, and also silences and mutes him.
* Bloodseeker's 
Rupture shows a clear red trail effect on the real Phantom Lancer.
* Ancient Apparition's 
Ice Blast will only debuff Phantom Lancer and not his illusions.
* 
Grimstroke's 
Soulbind is undispellable.
* Shadow Demon's Demonic Purge is undispellable.
* 
Monkey King's 
Jingu Mastery is undispellable and puts a big yellow Mark over his head.
Additional:
* Phantom Lancer's strength is the sheer amount of illusions he can conjure, Dissimulate can be cast on an ally that he is focusing to quickly thin out his ranks
* Landing a upgraded Demonic Purge on the real Phantom Lancer prevents him from making very many illusions (His only source being Doppelganger), You can reapply as needed if you have the Shard
* Disrupting Phantom Lancer allows you to create multiple extra illusions with Juxtapose, As he is a common carrier of 
Diffusal Blade, you can also drain the mana of any nearby heros
Shadow Demon
* Disruption instantly removes Phantom Embrace, and can potentially save allies affected by Soulbind.
* Demonic Purge dispels Ink Swell.
Kunkka
* The slow from Torrent makes Crystal Maiden's already bad movement speed even worse.
* Kunkka has many tools to interrupt Freezing Field (most notably Torrent, Ghostship and Torrent Storm from Aghanim's Scepter), as she is an easy target while channeling it.
* It is worth noting that most of Kunkka's abilities do not pierce through spell immunity, so purchasing a Black King Bar might help Crystal Maiden in this regard.
Kunkka
* Tidebringer pressures Invoker easily in lane due to Invoker's low health and armor in the early game.
Shadow Demon
* Disruption can save an ally from a fatal Reaper's Scythe.
* Demonic Purge can remove Ghost Shroud, making Necrophos vulnerable to physical damage and preventing him from regenerating health.
Shadow Demon
* In the laning stage, making illusions of Venomancer will turn his 
Poison Sting back at him, making for an easy gank at level one, and for later when your mid comes for ganks.
Kunkka
* X Marks the Spot will return Underlord or his teammate if they escape with 
Fiend's Gate.
* Torrent, Ghostship, Torrent Storm from Aghanim's Scepter and Tidal Wave from Aghanim's Shard are all excellent abilities for intercepting Underlord and his team if Underlord chooses to travel to the designated point of the map with Fiend's Gate.
Kunkka
* X Marks the Spot negates Stampede.
Kunkka
* Ghostship helps your team soak up damage from 
Chaotic Offering and hit summons hard.
* Tidebringer clears summons later in the game.
* Most of your spells can interrupt 
Upheaval.
Kunkka
* Ghostship helps your team soak up damage from 
Epicenter, especially if he initiates during the battle.
* 
Sand King can't dodge X Marks the Spot - Torrent combo by his abilities. Torrent drags him out of his 
Sand Storm
Shadow Demon
* Disruption will save Shadow Demon's teammates from being killed by Counter Helix or Culling Blade.
* Demonic Purge slows Axe to a crawl, making him nearly useless after initiating. If Shadow Demon has Aghanim's Scepter, it will also break Counter Helix.
* 
Demonic Cleanse clears Battle Hunger and Aghanim's Shard Counter Helix Damage Reduction, both allowing targets to escape and reducing your own survivability.
Additional:
* While it is unwise to encounter Axe alone, Disruption can be used to save your allies from Axe's initiate 
Berserker's Call, or, if timed correctly, from his 
Culling Blade.
* Illusions spawned from Axe has the Counter Helix passive, which with deal some nasty damage if an enemy focuses them
* Your upgraded Demonic Purge breaks Axe's primary damage output: 
Counter Helix, This can be used on him during Berserker's Call to seriously hinder him.
* Demonic Cleanse will clear 
Battle Hunger, which is Axe's method of catching heroes, and Shard upgraded Counter Helix's Damage Reduction, which is one of Axe's primary survivability abilities.
Kunkka
* X Marks the Spot prevents Broodmother from escaping.
* Tidebringer can clear Broodmother's spiders if they get in range.
Additional:
* Kunkka's entire kit is great for taking out multiple units at once.
* Tidebringer's cleave will split through a wave of spiderlings.
* X Marks the Spot is great for dragging Broodmother back out of her web for Kunkka's team to set up on her.
* Torrent and Ghostship will demolish any spiderlings within the radius.
Shadow Demon
* Disruption can protect Shadow Demon's allies from Fortune's End, preserving healing or buffs. It can also catch Oracle's allies, allowing Shadow Poison to be used without being dispelled.
* Demonic Purge prevents over-time healing during False Promise, such as Purifying Flames and 
Urn of Shadows. If he has Aghanim's Scepter, this issue can persist for longer or on multiple allies.
* It will not, however, prevent healing from instant abilities, items, or auras, making 
Mekansm a good choice against him.
Shadow Demon
* Shadow Demon with an Aghanim's Scepter will use Demonic Purge to disable Curse of Avernus and the passive component of Borrowed Time. If this is combined with a silence, Borrowed Time will not trigger at all.
* Even without Aghanim's Scepter, he can still waste Borrowed Time with Disruption. Curse of Avernus fully works on illusions, turning the passive ability against him.
Kunkka
* Heroes with strong area-of-effect damage can make quick work of Chen's converted creeps and at same time gain farm: 
Magnus, 
Jakiro, Shadow Fiend, Kunkka, 
Luna, 
Dragon Knight, 
Medusa, Alchemist.
Shadow Demon
* Heroes with break can disable Untouchable for a while: Doom and Shadow Demon (via Aghanim's Scepter), Viper, 
Shadow Shaman with Hex Breaks talent.
Kunkka
* Similarly, heroes with low cooldown teleports can be afraid to split push against X Marks the Spot, such as Tinker and Nature's Prophet.
* In general, highly mobile heroes like Earth Spirit or Storm Spirit are at a disadvantage against X Marks the Spot.
* Similarly, heroes with low cooldown teleports can be afraid to split push against X Marks the Spot, such as Tinker and Nature's Prophet.
Shadow Demon
* Heroes that lose a great amount of damage output and become less threatening: 
Phantom Assassin, Sven, 
Slark, Phantom Lancer.
* Once you have an Aghanim's Scepter, Shadow Demon instantly reaches a new power spike and becomes a counter for a variety of heroes that have strong passives.
* Heroes that lose a great amount of their tankiness and become easier to finish off: 
Bristleback, 
Spectre, Phantom Assassin, 
Enchantress, Dragon Knight.
* Heroes that lose a great amount of damage output and become less threatening: Phantom Assassin, Sven, Slark, Phantom Lancer.
* You can always stack camps and farm the scepter with Shadow Poison.
Kunkka
* Heroes that can negate Hoodwink's mobility: Kunkka, Disruptor, 
Mars.
Shadow Demon
* Shadow Demon's Demonic Purge with Aghanim's Scepter disables Bristleback's passives.
Shadow Demon
* Heroes that lose a great amount of damage output and become less threatening: Phantom Assassin, Sven, Slark, Phantom Lancer.

* Heroes that lose a great amount of damage output and become less threatening: Phantom Assassin, Sven, Slark, Phantom Lancer.
* You can always stack camps and farm the scepter with Shadow Poison.
Shadow Demon
* Primal Beast really suffers against supports he cannot bully in the lane: this includes Dazzle, Shadow Demon and 
Dark Willow since they can use their respective abilities to stop Primal Beast from dealing burst damage, or make it hard for him to stay in range.
Shadow Demon
* Heroes who can summon illusions and summons because Terrorblade has no abilities to deal with multiple enemies at once outside Reflection: Shadow Shaman, 
Naga Siren, 
Broodmother, 
Lycan, 
Enigma, Chaos Knight, Phantom Lancer, Shadow Demon, 
Dark Seer, Nature's Prophet, Invoker, 
Morphling, 
Visage, Grimstroke with Aghanim's Scepter.

* Heroes that lose a great amount of damage output and become less threatening: Phantom Assassin, Sven, Slark, Phantom Lancer.
* You can always stack camps and farm the scepter with Shadow Poison.
Kunkka
* Any hero who can counter-initiate in anticipation without getting caught in Reverse Polarity: Sven, Omniknight, Enigma, Luna, Naga Siren, Mars, Jakiro, 
Venomancer, 
Elder Titan, 
Faceless Void, Rubick, Keeper of the Light, Pugna, Invoker, Spectre, Alchemist, Treant Protector, 
Lina, Oracle, 
Zeus, Shadow Shaman, 
Phoenix, 
Razor, 
Huskar, Batrider, Kunkka, 
Tidehunter, Wraith King, Sand King, Medusa, Dawnbreaker.
Shadow Demon
* Heroes with high physical damage output but lack of reliable escape mechanisms are always a good target for a solo gank: Sniper, Shadow Fiend, Troll Warlord, Drow Ranger. Those heroes, however, are dangerous if they manage to close the gap, so take caution.

Shadow Demon
* 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
Kunkka
* Heroes that can keep Marci for a long time in one place so she can't pursue her targets, like Bane, 
Lion, Shadow Shaman, Invoker, Disruptor and Kunkka.
Kunkka
* X Marks the Spot is a counter to Disruptor's 
Glimpse, but you need quick reactions to pull it off.
Kunkka
* Heroes with long range abilities are also able to touch Zeus, such as 
Clockwerk, Kunkka, 
Puck, 
Skywrath Mage, 
Spirit Breaker, Tusk and others.
Kunkka
* In general, highly mobile heroes like Earth Spirit or Storm Spirit are at a disadvantage against X Marks the Spot.
* Similarly, heroes with low cooldown teleports can be afraid to split push against X Marks the Spot, such as Tinker and Nature's Prophet.
Shadow Demon
* Heroes with high physical damage output but lack of reliable escape mechanisms are always a good target for a solo gank: Sniper, Shadow Fiend, Troll Warlord, Drow Ranger. Those heroes, however, are dangerous if they manage to close the gap, so take caution.
Shadow Demon
* Heroes with hiding abilities can protect disabled allies: Outworld Destroyer, Shadow Demon, Tusk, Phoenix with Aghanim's Scepter.
Shadow Demon
* Heroes who can hide the Dueled target (Outworld Destroyer, Shadow Demon, Tusk, Phoenix with Aghanim's Scepter etc).
Additional:
* Disruption can save allies and mess up an initiation from an enemy Legion Commander. Using Disruption on your ally that is affected by Duel will leave her totally exposed without the benefit of the life steal from 
Moment of Courage. A precise decision to Disrupt Legion Commander or her victim is crucial to waste Duel's potential.
* Demonic Purge cannot be dispelled by a hard dispel from 
Press the Attack, which in turn can be dispelled by your ultimate.
Shadow Demon
* Heroes that can punish aggressive heroes, such as: Leshrac, Shadow Demon, Pugna, 
Death Prophet.
Kunkka
* Heroes with cleave or multi-target attacks can quickly take on Familiars and reduce Visage's firepower like 
Gyrocopter, Kunkka, Magnus and Medusa.
Shadow Demon
* Chaos Knight, Lone Druid, Meepo and Arc Warden can be hard targets since Shadow Demon's spells are ill-suited to fight many enemies at once.
Kunkka
* Tidebringer, Torrent and Ghostship destroys Chaos Knight's 
Phantasm army all through the game.
Shadow Demon
* Illusions and summons are double-edge sword type of matchup for Luna. On one hand, they can tank damage from Eclipse, but on the other hand, she can easily clear them before Eclipse with Moon Glaives. Examples include Spectre, Shadow Demon, Phantom Lancer, Naga Siren, Chaos Knight, 
Terrorblade) or bring other units into the fight (such as Nature's Prophet, Lone Druid, 
Chen, Enchantress, Meepo and Arc Warden).
Shadow Demon
* Demonic Purge takes off Luna's superior mobility, removing the need for chasing her and allowing your team to reposition in team fights or escape when at low HP. If Shadow Demon has Aghanim's Scepter it will also take away glaive bounces and extra damage from Luna's passive. And Luna's commonly items Manta Style and Black King Bar does not work dispell to Demonic Purge
* Luna's illusions created by Disruption are very valuable with their 
Moon Glaives. These will effectively counter her pushing attempts and are painfully effective in team fights.
* Disruption can be used to save an ally from 
Eclipse.
* For the same reasons, Shadow Demon makes a very powerful ally for Luna when they are in the same team.

Shadow Demon
* Lycan and Weaver has abilities that allow them to move at maximum movement speed, and those abilities can't be dispelled, potentially wasting the slow from Demonic Purge.
Kunkka
* Tidebringer's cleave will cripple any of his summons.
* Could potentially build Heaven's Halberd to cripple Lycan even more.
Additional:
* Tidebringer can be used to kill Lycan's summons.
* Can also build into 
Heaven's Halberd which will disable Lycan's auto attacks, crippling him even more.
Shadow Demon
* Disruption is not reliable enough to catch an Ember Spirit with a backup 
Fire Remnant.
* 
Sleight of Fist will also make quick work of the spawned illusions.
* The best you can do against an Ember Spirit is to dispel his 
Flame Guard with your Demonic Purge.
Kunkka
* Using X Marks the spot Kunkka can prevent Ember Spirit from escaping with Activate Fire Remnant, until he purchase Eul's Scepter of Divinity or Linken's Sphere.
Shadow Demon
* All of Queen of Pain's abilities are active, making Demonic Purge break from Aghanim's Scepter useless.
* However, Demonic Purge can help his allies kill a squishy Queen of Pain.
* 
Blink allows Queen of Pain to escape from Shadow Demon's abilities if he doesn't have disables.
* An attempt to save an ally using Disruption can easily become a perfect setup for a 
Sonic Wave for the enemy.
Kunkka
* Ghostship helps your team soak up damage from Sonic Wave and 
Scream of Pain.
* 
Queen of Pain can't escape easily from X Marks the Spot - Torrent combo.
* Outlanes Queen of Pain on the midline, due to the fact that Queen of Pain has a small reserve of health at the beginning of the game, and she suffers very much from Tidebringer, which is why she is forced to either spend money on Tango, or skip creeps and run for bounty runes, and Kunkka at this time will gain an advantage in level and gold.

* Kunkka will catch her in X Marks the Spot and allow his team to kill her for stun from Torrent, because Queen of Pain has no way to avoid the cross X Marks the Spot before buying Black King Bar.
Kunkka
* Since Tidebringer has a 4 second cooldown, Kunkka has little availability to manfight Huskar.
Shadow Demon
* Shadow Demon's Shadow Poison can quickly stack to the point where Huskars generally low health is easily finished off.
* Shadow Demon's Disruption can turn Huskar's high attack speed and regeneration against him, It also makes him an easy target for Shadow Poison,
* Shadow Demon commonly builds a 
Meteor Hammer, allowing him to land a heavy stun on Huskar
* Shadow Demon's upgraded Demonic Purge breaks Huskar, It also pierces Spell Immunity, Without his passive for 7 seconds Huskar quickly falls in battle
* However note that Shadow Demon is a squishy target and you can often overwhelm him if he is alone, But he can still Disrupt you to escape
Additional:
* Shadow Poison can quickly stack up on Huskar, And with his naturally low health you don't need as many stacks to be effective.
* Disruption turns Huskars high attack speed against him, They also have the highest survivability as illusions due to his passive 
Berserker's Blood, It also allows you to put Shadow Poison stacks on him,
* Dissimulate turns Huskar's burning damage against his team, You can cast it on an ally who is taking a bunch of 
Burning Spear stacks and cause Huskar to take high amounts of damage as well
* Scepter upgraded Demonic Purge is your most effective weapon against him, It's 7 second Break causes him to quickly die in battle
Shadow Demon
* Chaos Knight, Lone Druid, Meepo and Arc Warden can be hard targets since Shadow Demon's spells are ill-suited to fight many enemies at once.
Shadow Demon
* Heroes with summons or illusions can counter Flux, such as 
Beastmaster , Chen, or Shadow Demon.
Kunkka
* 
Astral Imprisonment can allow Outworld Destroyer to save himself or allies from Kunkka's full kit.
* 
Sanity's Eclipse deal a large amount of damage, as Kunkka's mana pool is much smaller than Outworld Destroyer's.
* 
Arcane Orb deals pure damage, shredding through Kunkka and his team even with Ghostship's buff.
Shadow Demon
* Shadow Demon's Disruption will allow his allies to maneuver around you. It can also be used to protect an ally from your abilities, or Astral Imprisonment - Meteor Hammer combo.
* 
Disseminate turns your high damage Arcane Orb and Sanitiy's Eclipse against you and your teammates.
* Scepter upgraded Demonic Purge will break your Essence Flux passive for 7 seconds, preventing you from regaining mana, and severely hindering your damage output.
Shadow Demon
* Poof will destroy Shadow Demon's illusions created by Disruption and quickly escapes from Shadow Poison & Demonic Purge.
Kunkka
* X Marks the Spot is good to prevent a single meepo from escaping from a deadly situation.
* Tidebringer, Torrent and Ghostship destroys Meepo's clones.
Additional:
* Tidebringer's cleave damage can wear down Meepo's clones quickly. It can also give Meepo problems in the lane, due to his melee range and initially low health pool.
* Ghostship and Torrent can effectively disable Meepo while dealing heavy damage.
* X Marks the Spot prevents attempts to escape using Poof.
Kunkka
* Kunkka relies on his powerful AOE spells to turn the tides of teamfights. He cannot use them while silenced.
Last Word can mess up Kunkka's ability synergy, silencing him in the middle of his strong combo.
Global Silence can disable Kunkka's spell casting from anywhere on the map, even if Kunkka is spell immune at the time.
*
*
Shadow Demon
* Shadow Demon's main source of damage is his low cooldown, high damage spells - meaning Last Word and Global Silence will pretty much take him out of the game for the duration.
* Shadow Demon likes to spam his abilities, which makes him vulnerable to Arcane Curse.
* If Shadow Demon dies near Silencer, he will lose intelligence, reducing his mana pool, mana regen, and attack damage. Furthermore, if the game is long and Shadow Demon dies often, the intelligence losses will also reduce his spell damage.
