* With his AoE damage, Jakiro can easily kill Chaos Knight's Phantasm illusions.
* Chaos Knight usually doesn't buy a Black King Bar, making him vulnerable to an Ice Path into Macropyre combination.
Additional:
* With his AoE damage, Jakiro can easily kill Chaos Knight's Phantasm illusions.
* Chaos Knight usually doesn't buy a Black King Bar, making him vulnerable to an Ice Path into Macropyre combination.

* Jakiro's wide area-of-effect abilities allow him to clear the waves of Terrorblade's illusions and to damage real Terroblade.
* Both, Liquid Fire and Liquid Frost from Aghanim's Shard deal magical damage, which can bypass Terrorblade's high armor.
* Jakiro often buys Hurricane Pike, which combined with +275 Attack Range talent allows Jakiro to harass Terrorblade from safe distance without getting in range of Sunder and outrange Terrorblade greatly, even during Metamorphosis.
* Aghanim's Scepter upgraded Macropyre can deal huge pure damage to Terrorblade and his illusions and can hurt real Terrorblade even if he is protected by Black King Bar thanks to it's ability to pierce spell immunity when upgraded.
* Just bear in mind, however, that Jakiro's abilites are all dealing damage-over-time, so a well-timed Sunder may spell a doom for Jakiro if Terrorblade can get close to him unless Jakiro builds Black King Bar or Linken's Sphere and other items that can give him a burst damage.

* Flak Cannon destroys Terrorblade's illusions very quickly.

* Puck's area of effect nukes in the form of Illusory Orb and Waning Rift clears Phantasm illusions from the early game to mid game.
* Phase Shift can be used to disjoint Chaos Bolt.

* All of Puck's damaging spells deal AoE magic damage, which focuses on Terrorblade's low health pool and ignores his armor.
* Puck's spells are also great at quickly clearing all of Terrorblade's illusions. Even a single Illusory Orb is enough to drop their health very low, allowing creeps, towers or allies to finish them off very quickly. Waning Rift and Illusory Orb together are usually enough to clear his illusions.
* Waning Rift prevents Terrorblade from casting Sunder at low health.
* Puck is a common Dagon carrier, making it possible to finish off Terrorblade before he has a chance to Sunder.

* Storm Hammer's faster projectile speed and cast time allows Sven to stun Chaos Knight and his illusions before he can cast Chaos Bolt.

* Whirling Death directly reduces Strength from both Chaos Knight and his Phantasm illusions, reducing both the damage output and raw health that the hero relies on.
* Reactive Armor quickly builds stacks against Phantasm illusions, making Timbersaw hard to kill.
Additional:
* Reactive Armor helps Timbersaw to endure the damage from Chaos Bolt and Reality Rift combo.
* Timbersaw's large amount of pure damage AoE nukes clears Chaos Knight's illusions quickly, drastically reducing his damage.

* Timbersaw's abilities combos all deal magical and pure damage, completely ignoring Terrorblade's high base armor and clearing his illusions very quickly due to the AoE damage.
* Reactive Armor negates most of Terrorblade's damage against Timbersaw, and its high health regeneration and armor bonuses can help Timbersaw survive after Terrorblade has used Sunder on him.
Additional:
* Timbersaw can take down Terrorblade's illusions with his area damage burst.
* Reactive Armor plus another armor item reduce much of Terrorblade's damage.

* Heroes that rely on illusions will suffer against Ion Shell, which kills them very quickly: Phantom Lancer, Chaos Knight, Naga Siren, Meepo.

* Dark Seer's Vacuum and Ion Shell allows him to clear the wave of Terrorblade's illusions.
* Wall of Replica and Normal Punch from Aghanim's Shard can create stronger illusions of Terrorblade.
* If Dark Seer can use Vacuum to help teammates land their AoE skills, Terrorblade will be quickly killed before he even gets a chance to use Sunder.
Additional:
* Dark Seer's Vacuum and Ion Shell allows him to clear a wave of Terrorblade's illusions.
* Because Terrorblade often builds items that require Ultimate Orb like Manta Style and Eye of Skadi, Dark Seer can create a very strong illusion of Terrorblade with Wall of Replica and Normal Punch from Aghanim's Scepter.
* If Dark Seer can use Vacuum to help teammates land their AoE abilities, Terrorblade will be quickly killed before he even gets a chance to use Sunder.

* Once he buys Aghanim's Shard, Dazzle's Poison Touch can hex enemies, and hex can instantly kill illusions, making Dazzle strong against heroes who rely on illusions. Bear in mind that Chaos Knight is the exception because his Phantasms are strong illusions that are immune to abilities that can instantly kill illusions.

* Shallow Grave can be used to save an ally whom Terrorblade has used Sunder on under the condition Dazzle is quick enough to do it.
* Poison Touch upgraded with Aghanim's Shard can be used to easily kill many of Terrorblade's illusions, it can also hex the real Terrorblade, silencing him, disarming him, slowing him, and muting him.
* Bad Juju can weaken Terrorblade's armor every time Dazzle casts a spell while strengthening armor of Dazzle's allies.
Additional:
* Shallow Grave can be used to save an ally whom Terrorblade has used Sunder on under the condition Dazzle is quick enough to do it.
* Aghanim's Shard upgraded Poison Touch can be used to easily kill many of Terrorblade's illusions from both Conjure Image and Manta Style, it can also hex the real Terrorblade, silencing him, disarming him, slowing him, and muting him.

* Heroes with strong area damage to destroy Phantasm illusions: Axe, Ember Spirit, Legion Commander, Phoenix

* Duel's long duration prevents Terrorblade from swapping his health with Sunder.
* Overwhelming Odds deals high damage to Terrorblade's illusions.

* Echo Slam will deal a colossal amount of damage to your Phantasms, as will Fissure at lower levels.
* The area stuns from Aftershock will always stun Chaos Knight's illusions, since they can't use Black King Bar.
* However, Earthshaker should not attempt to fight a farmed Chaos Knight, since he will be completely obliterated by Chaos Knight's colossal damage output, even if he managed to land an Echo Slam
Additional:
* Echo Slam's damage potential increases due to Chaos Knight's Phantasm illusions.

* Heroes with abilities that can lock down Terrorblade and prevent him from using Sunder: Earthshaker, Faceless Void, Legion Commander, Shadow Shaman.

* 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 Dark Rift 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.

* 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.

* Juxtapose allows Phantom Lancer to overwhelm Chaos Knight due to his single-target abilities.
* Doppelganger can be used to dodge Chaos Bolt.
* Since Phantom Lancer builds Diffusal Blade often, it can quickly drain Chaos Knight's low mana pool, leaving him unable to cast spells.
Additional:
* Chaos Knight's single target abilities are difficult to target against Phantom Lancer's illusions.
* Chaos Knight's lack of mobility makes him an easy target for Phantom Lancer to Phantom Rush and drain his already low mana pool.

* Heroes with single-target abilities and low-mobility are all an exceptionally easy targets for Phantom Rush: Terrorblade, Chaos Knight, Wraith King

Additional:
* With no wave clear and mostly focus on dealing single target damage, Terrorblade will be overwhelmed in no time due to Juxtapose.
* Reflection can be dispeled instantly with Doppelganger.
* As Phantom Lancer is a natural Diffusal Blade carrier, he can drain Terrorblade's mana, leaving Terrorblade no chance to use Sunder to save himself.
* Besides Reflection, Terrorblade has no other ways to deal with Phantom Lancer's illusions. And what's worse is that Phantom Lancer can much easily detect the real Terrorblade due to Conjure Image having illusions having different colors.

* Sand King's massive area damage output, particularly Epicenter, allows him to quickly take down Chaos Knight and his illusions.
* Sand King can also apply Caustic Finale to illusions with attacks for extra damage when they die.

* Because of his massive AoE damage, Sand King is very effective against illusion heroes: Chaos Knight, Phantom Lancer, Terrorblade,...

* Heroes with gap closing abilities will be easy targets for Berserker's Call: Phantom Assassin, Faceless Void, Slark, Chaos Knight, Morphling, Queen of Pain

Additional:
* Berserker's Call allows Axe to lock down Chaos Knight and his illusions even through Black King Bar.
* Counter Helix combined with Blade Mail clears illusions out in no time.

* Terrorblade's low base health and lack of mobility make him an easy target for Axe to initiate on, and kill.
* Counter Helix will trigger from, and destroy many of Terrorblade illusions.
Additional:
* Berserker's Call and Counter Helix together can be devastating to Terrorblade, especially if Terrorblade has a lot of illusions. Their high attack speed will trigger Counter Helix a lot, and the pure damage will quickly slice through Terrorblade's low health and kill his illusions. More importantly, the Berserker's Call can pierce through spell immunity from Black King Bar, Terrorblade's only survival item besides Manta Style which cannot be used to dispel Berserker's Call. With enough burst damage by Axe's teammates, Terrorblade can be finished off even before taunt duration runs out and he gets a chance to save himself with Sunder.
* Culling Blade can finish off Terrorblade before he has the chance to Sunder due to his low health in the early to mid game. And every time Terrorblade or any of his allies are successfully killed by Culling Blade, Axe permanently gains armor from it, which in combination with armor items that Axe often purchases like Blade Mail, Crimson Guard, Assault Cuirass and Shiva's Guard can make Terrorblade's attacks only tickle Axe, even during Metamorphosis.
* Terrorblade's low base health and lack of mobility make him an easy target for Axe to initiate on, and kill.

* Heroes with strong area damage to destroy Phantasm illusions: Axe, Ember Spirit, Legion Commander, Phoenix

Additional:
* Ember Spirit is evasive and can dodge close encounters with melee heroes like Chaos Knight. Ember Spirit can't be caught with the slow from Reality Rift, and Flame Guard and Sleight of Fist can bring Phantasm's illusions down quickly.

* Ember Spirit can deal devastating damage to illusion heroes like Terrorblade with Sleight of Fist. Terrorblade also has no way of preventing Ember Spirit from getting Activate Fire Remnant off. Additionally, Ember Spirit's ability to fight from long range as well as his wide skill set won't give many opportunities for Terrorblade to get Sunder off.
Additional:
* Ember Spirit can deal devastating damage to Terrorblade and his illusions with Sleight of Fist.
* Terrorblade has no disable to lock down Ember Spirit and prevent him from escaping with Fire Remnant. In addition, he doesn't like purchasing disabling items like Scythe of Vyse or Abyssal Blade, which are the only solutions to deal with Ember Spirit.

* Cold Embrace protects Reality Rift targets.
* Winter's Curse turns Phantasm illusions against Chaos Knight or a teammate.
* Splinter Blast deals decent area damage to Phantasm illusions.
* Arctic Burn's percentage-based damage quickly wears down Chaos Knight's high max health.

* Alternatively, Winter's Curse can make Chaos Knight and all his illusions attack one of his allies.
* Cold Embrace protects ally who is focused by Chaos Knight.
* Splinter Blast deals decent area damage to Chaos Knight's illusions.
* Chaos Knight's high health pool and tendency to not build magic resistance items will make Arctic Burn deal a lot of damage to him and his illusions.

* Terrorblade and his illusions deal huge damage, which might used against him and his team with Winter's Curse.

* Untouchable will significantly slow down Chaos Knight's physical damage with Phantasm.
* Impetus deals double damage to illusions, making it effective against Phantasm.
Additional:
* Untouchable makes all of Chais Knight's attacks slow therefore he is unable to deal damage, especially his critical damage of Chaos Strike, also enables Enchantress to escape easily from his attacks.
* However, Reality Rift can still pose a danger to Enchantress because Chaos Knight can decrease a good amount of armor, making it dangerous because of her little armor stat, as he can burst down Enchantress easily if any of Chaos Knight's allies can apply a break on Enchantress.

* Heroes that can dominate his illusions or create their own illusions of him: Dark Seer, Morphling, Enchantress, Shadow Demon, Grimstroke with Aghanim's Scepter.

* Heroes who are reliant on illusions or summons: Chaos Knight, Broodmother, Naga Siren.

* Terrorblade's lack of escape mechanisms makes it hard for him to escape both Ink Swell and Stroke of Fate.
* Phantom's Embrace's silence will also prevent him from casting Sunder to save himself.

* Techies has great area of effect damage to deal with Phantasm illusions.
* Blast Off silences Chaos Knight, stopping him from using his disables and allowing his teammates to walk away from his heavy damage.
* Reactive Tazer will disarm all of Chaos Knight's illusions even if he has activated his Black King Bar.

* Techies deals lots of magical damage with Sticky Bomb, Blast Off! and Proximity Mines that bypasses Terrorblade's high armor and can punish his low max life.
* Sticky Bomb is easy to land on a large clump of Terrorblade illusions and will damage and slow Terrorblade and all of his illusions if he can't quickly move the right one away.
* Reactive Tazer upgraded with Aghanim's Scepter can be used to protect an ally getting attacked by Terrorblade. Further, it disarms all of his illusions even while he has activated Black King Bar, greatly decreasing his damage.
* Blast Off! silences Terrorblade, preventing him from casting Sunder.

* Illusion-based and multi-unit heroes can take advantage of Chaos Knight's lack of area damage: Naga Siren, Phantom Lancer, Broodmother

* 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 who are illusion based, or even heroes who frequently build Manta Style can be cleared quickly by Pangolier's high damage, or lose their damage ouput because of Lucky Shot: Chaos Knight, Naga Siren

* Heroes who rely on skills to become a heavy hitter in a certain amount of time can waste their timing because of a lucky Lucky Shot's disarm: Terrorblade, Sven, Clinkz, Windranger, Alchemist, Dragon Knight, Legion Commander

* One of Lion's level 20 talents lets Mana Drain affect 2 secondary targets. This can make things difficult for heroes like Phantom Lancer, Chaos Knight, and Terrorblade who rely on illusion armies.
* Mana Drain and Hex instantly kill any illusions. Finger of Death upgraded with Aghanim's Scepter also shreds most illusions.

* Guardian Angel blocks all of Chaos Knight's damage for a long duration.
Additional:
* Phantasms can be easily killed with Purification.
* Heavenly Grace dispels the stun from Chaos Bolt and the armor reduction from Reality Rift.
* Guardian Angel works well against Chaos Knight's overwhelming reliance on physical burst damage.

* Terrorblade is a double-edged sword type of matchup against Silencer. Although Terrorblade is more reliant on direct attacks to be effective, he relies on Sunder to save himself and stay alive and Last Word and Global Silence prevent him from doing that.
* Arcane Curse and Aghanim's Scepter upgraded Last Word help Silencer deal with Terrorblade's illusions from Conjure Image and Manta Style.
* With Last Word Mutes talent, Silencer can not only disable Terrorblade from turning tables with Sunder, but can also prevent him from using Manta Style and Black King Bar, items Terrorblade needs to be effective in teamfights.
* Glaives of Wisdom deals pure damage against the real Terrorblade, bypassing his high base armor.
* Global Silence can silence Terrorblade even if he has Black King Bar active, though bear in mind that Terrorblade can dispel Global Silence with Manta Style and Black King Bar if the Global Silence was activated first.
Additional:
* Silencer is a double-edged sword type of matchup against Terrorblade. Although Terrorblade is more reliant on direct attacks to be effective, he relies on Sunder to save himself and stay alive and Last Word and Global Silence prevent him from doing that.
* Arcane Curse, Glaives of Wisdom upgraded with 2 Glaives of Wisdom Bounces talent and Aghanim's Scepter upgraded Last Word help Silencer deal with Terrorblade's illusions from Conjure Image and Manta Style.
* With Last Word Mutes talent, Silencer can not only disable Terrorblade from turning tables with Sunder, but can also prevent him from using Manta Style and Black King Bar, items Terrorblade needs to be effective in teamfights.
* Glaives of Wisdom deals pure damage against the real Terrorblade, bypassing his high base armor. Later it can be upgraded with 2 Glaives of Wisdom Bounces talent to deal against Terrorblade's illusions.
* Global Silence can silence Terrorblade even if he has Black King Bar active, though bear in mind that Terrorblade can dispel Global Silence with Manta Style and Black King Bar if the Global Silence was activated first.

* Storm's Dispel Magic combined with Thunder Clap deals high damage against Chaos Knight's illusions even in the late game.
* Chaos Knight's reliance on physical damage is easily hindered by Drunken Brawler.

Additional:
* Dispel Magic from {U:Storm} can instantly kill Phantasms early on, and can still deal a lot of damage to them late game, revealing the real Chaos Knight.

* Lich's Chain Frost, especially after obtaining its respective talent that provides unlimited bounces, can take out all of Chaos Knight's illusions quickly.
* An Aghanim's Scepter-upgraded Sinister Gaze can hypnotize Chaos Knight and his illusions while also draining his already low mana pool.
Additional:
* Chain Frost can eliminate Chaos Knight's Phantasm army, especially after he clumped up using Reality Rift.
* Frost Shield will heavily reduce his army's effectiveness.

* Using Reality Rift sets up a Reverse Polarity on Chaos Knight and his illusions.
* Shockwave and Skewer kill Phantasm's illusions quickly, as can Empower cast on a melee carry.
Additional:
* All Magnus abilities are very good against Chaos Knight's Phantasm illusions.

* Terrorblade has a high base armor, and relies on many ultimate orb-based items (Manta Style and Eye of Skadi). Natural Order affects armor gained from agility, essentially reducing armor to zero if all armor is gained from agility. That effect combined with Terrorblade's low health can make a Elder Titan with an early value point in Natural Order a dangerous foe.
* Terrorblade's illusions are often grouped up in teamfight, making them more vulnerable to Echo Stomp.
Additional:
* Echo Stomp and Astral Spirit allow the enemy team to coordinate a kill on Terrorblade before he can Sunder.
* Natural Order cripples Terrorblade's armor that he crucially needs to survive due to his low strength gain.

* Heroes that have high health but little to no magic resistance are easy prey for Necrophos, as no matter how high they build their health up, Reaper's Scythe will kill them outright as long as they fall under a certain threshold, and Heartstopper Aura will deal the same amount of damage regardless, decaying their health the longer they stay within range. As such, Strength heroes like Chaos Knight, Centaur Warrunner or Magnus are good targets for his ultimate.

* Reaper's Scythe can kill Terrorblade quickly before he has chance to use Sunder because it instantly disables an enemy hero on which it's casted.
* Even if Terrorblade succeeds to use Sunder on Necrophos, Necrophos can still protect himself from Terroblade's high attack damage with Ghost Shroud and Death Seeker from Aghanim's Shard, which can turn him ethereal and prevent Terrorblade from attacking him. Ghost Shroud also amplifies any healing Necrophos receives for it's duration, which in combination with Death Pulse allows Necrophos to easily nullify Sunder's effects while Death Seeker can be used to disarm Terrorblade and amplify any magical damage he will take.
* Necrophos often buys Radiance, which combined with Death Pulse can help him deal with Terrorblade's illusions from Conjure Image and Manta Style. Death Seeker from Aghanim's Shard can also spread on Terrorblade's illusions upon impact.
* Terrorblade depends entirely on physical attacks and his damage output is 100% physical. Therefore, since he has no any sources of magical damage output and hates going for items that deal magical damage like Dagon, Ethereal Blade and Revenant's Brooch, Ghost Shroud will render him unable to damage Necrophos at all.

* Nyx Assassin deals large amounts of pure damage with Vendetta and magical damage with Impale and Mana Burn, allowing him to ignore Terrorblade's armor and burst his low health pool down before he can use Sunder.
* Nyx Assassin commonly buys Urn of Shadows, Dagon and Meteor Hammer which deal magic damage that ignore Terrorblade's armor.
* Mana Burn might drain too much mana for Terrorblade to be able to use Sunder if he isn't careful in the early to mid game.

* Black Hole usually catches Chaos Knight with all his illusions.
* Midnight Pulse deals damage based on current health, quickly killing Phantasm illusions.

* 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.

* Rolling Boulder and Geomagnetic Grip prevent Terrorblade from using Sunder.
* Magnetize Does heavy magic damage to Terrorblade and his illusions that bypasses his high base armor.

* Heroes the make heavy use of illusions, like Chaos Knight, Phantom Lancer, Terrorblade, or Spectre can suffer from Crystal Maiden, as Freezing Field can quickly kill off the entire horde if not stopped.

* While Terrorblade can kill Crystal Maiden due to her low durability with Reflection and Metamorphosis, Crystal Maiden can do the same to him if he is not careful.
* Crystal Nova and Freezing Field can destroy Terrorblade's Illusions from Conjure Image and Manta Style while it can also kill Terrorblade from early to mid game if he has no Black King Bar.
* Terrorblade has no disable in his ability set at all and has no solutions to cancel it Freezing Field. In addition, he doesn't like purchasing disabling items like Scythe of Vyse or Abyssal Blade, which are the only solutions to deal with Crystal Maiden's Freezing Field outside of Black King Bar.
* Since Crystal Maiden often buys Black King Bar and Glimmer Cape, or it's alternative item Shadow Blade, as well as it's upgrade Silver Edge, Terrorblade will rarely have a chance to save himself against Crystal Maiden's damage output with Sunder.
Additional:
* While Terrorblade can easily kill Crystal Maiden due to her low durability and movement speed with Reflection and Metamorphosis, Crystal Maiden can do the same to him if he is not careful.
* Crystal Nova and Freezing Field can destroy Terrorblade's illusions from Conjure Image and Manta Style while it can also kill Terrorblade from early to mid game if he has no Black King Bar.
* Terrorblade has no disable in his ability set at all and has no solutions to cancel it Freezing Field. In addition, he doesn't like purchasing disabling items like Scythe of Vyse or Abyssal Blade, which are the only solutions to deal with Crystal Maiden's Freezing Field outside of Black King Bar.
* Since Crystal Maiden often buys Black King Bar and Glimmer Cape, or it's alternative items Shadow Blade, as well as it's upgrade Silver Edge or Linken's Sphere, Terrorblade will rarely have a chance to save himself against Crystal Maiden's damage output with Sunder.

* Terrorblade has low mobility, which makes it easy for Storm Spirit to kite him.
* Terrorblade gains a lot of agility and gains very low strength, which makes it easy to burst him down with Storm's magical damage.
* All of Terrorblade's abilities are easily avoided by Storm Spirit as he can simply use Ball Lightning, wasting the duration of Metamorphosis, Conjure Image, and Reflection.
* However, if Storm Spirit's Orchid Malevolence is on cooldown or if he doesn't have it, Terrorblade can easily use Sunder and kill a careless Storm Spirit.
Additional:
* Storm Spirit has heavy magic damage that bypasses Terroblade's high armor.
* Ball Lightning can either use to initiates Terroblade from distance or kite Terroblade from using Sunder as he has no source of disable to deal with Storm Spirit.

* Ravage damages and disables Chaos Knight and his illusions.
* Anchor Smash deals respectable area damage, especially to Phantasms and lowers Chaos Knight's damage.
* Kraken Shell dispels Chaos Bolt and Reality Rift while providing protection from damage.

* Void Spirit's high mobility becomes a nuisance to Terrorblade.
* Void Spirit's arsenal of magic damage is effective against Terrorblade's low strength.
* Terrorblade has no disables to prevent Void Spirit from escaping.

* Wukong's Command and Boundless Strike combo can easily cause havoc on Chaos Knight by destroying all of his powerful illusions.
* Chaos Knight without Phantasm cannot deal with Jingu Mastery at all.

* Tidebringer, Torrent and Ghostship destroys Chaos Knight's Phantasm army all through the game.

* Bulwark negates most of the physical damage from Terrorblade and his illusions.
* God's Rebuke and Spear of Mars can decimate Terrorblade's illusions quickly.

* Terrorblade's reliance on high armor while having a small health pool make him extremely vulnerable to Pierce the Veil.
* Gunslinger will make short work of Conjure Image.
* Reflection can not hurt Muerta when she has activated Pierce the Veil.

* Dragon Blood's armor bonus greatly reduces the damage dealt by Phantasm.
* Breathe Fire and Elder Dragon Form's splash damage quickly destroy illusions and reduces their damage output.

* With Aghanim's Scepter, Tinker's Laser completely stops Chaos Knight's damage, forcing him to buy either a Black King Bar for his own survivability while leaving his illusions still vulnerable, or a Monkey King Bar leaving him still vulnerable to Tinker's nukes, though improving his damage.
* Tinker rarely finds himself in the middle of a fight, which is where Chaos Knight typically thrives, and even in the rare cases of being so, at level 3 Tinker's constant rearm and blink away can kite and dodge Chaos Knight's spells reliably, so Chaos Knight has very little catch against Tinker's mobility. This gives Tinker impunity to create more chaos in a teamfight than Chaos Knight can control, laying down the field with March of the Machines and constantly being hit by rockets and lasers.

* An Aghanim's Scepter upgraded Laser allows Tinker to blind Terrorblade and his illusions.
* Tinker deals incredible amounts of pure and magical damage with Laser and Heat-Seeking Missile combined with Rearm, which will ignore Terrorblade's armor and be devastating to his low health pool.
* Tinker is a hero who very often goes for Blink Dagger, and because Terrorblade has no disable to lock down Tinker, he will be unable to catch up with him nor to prevent him from escaping with Boots of Travel.
Additional:
* Tinker can single-handedly stop Terrorblade's early-push and quickly clear his illusions with Laser (especially with Aghanim's Scepter) and March of Machines.
* Tinker has perfect tools to reveal Terrorblade from his illusions as well as to burst him down if he is low-health before he will be able Sunder.

* 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 who are reliant on illusions: Chaos Knight, Phantom Lancer, Naga Siren.

* Abaddon could punish Chaos Knight for using his Phantasm and Reality Rift combo on him with Aphotic Shield. Additionally, it provides extra protection against Chaos Knight's potential to take Abaddon down quickly.
* Furthermore, Abaddon's Borrowed Time makes it utterly impossible to burst Abaddon down, effectively reducing the amount of targets Chaos Knight can threaten by 1 for the entire game.

* Heroes who can negate effects of Sunder: Faceless Void's Time Walk, Weaver's Time Lapse, Broodmother's Insatiable Hunger, Abaddon's Borrowed Time and Troll Warlord's Battle Trance can nullify Sunder.

* Heroes who have channeling abilities because Terrorblade has no disables to cancel them at all and does not like buying disabling items at all: Enigma's Black Hole, Witch Doctor's Death Ward, Shadow Shaman's Shackles, Lion's Mana Drain, Bane's Fiend's Grip, Pudge's Dismember, Crystal Maiden's Freezing Field, Pugna's Life Drain, Dawnbreaker's Solar Guardian, and Naga Siren's Reel In from Aghanim's Scepter.

* Heroes with strong area damage to destroy Phantasm illusions: Axe, Ember Spirit, Legion Commander, Phoenix

* Heroes whose core item builds includes Monkey King Bar: Faceless Void, Windranger, Weaver, Juggernaut.

* Heroes with low health or rely on evasion can easily be bursted down, like Phantom Assassin or Terrorblade.

Additional:
* Laguna Blade is one of the best tools to kill Terrorblade before he can use Sunder due to its high magical (pure with Laguna Blade damage is Pure and pierces Spell Immunity talent) burst damage.
* Dragon Slave and Light Strike Array allows Lina to clear Terrorblade's illusions from both, Conjure Image and Manta Style.

* Heroes that have strong area-of-effect abilities and can stall pushes: Invoker, Keeper of the Light, Jakiro, Lina, Luna, Leshrac, Shadow Shaman.

* 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

* Heroes reliant on illusions or summons: Broodmother, Chaos Knight, Naga Siren.

* Unlike with other heroes who can summon illusions of themselves, Terrorblade's illusions from Conjure Image have different colors than other illusions which can be seen even by enemy team, which can also make Terrorblade weak even against heroes he naturally counters: Bane, Lifestealer, Spectre, Chaos Knight, Spirit Breaker, Sniper. Terrorblade's only solution to counter this problem is to get Manta Style as quickly as possible.

* 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.

* Maledict cannot be dispelled by Phantasm, and can be used to tag the real Chaos Knight hiding within his illusions.
* If Witch Doctor has an Aghanim's Scepter, Death Ward will bounce between Chaos Knight's illusions, destroying them quickly.
* However, Death Ward is easily interrupted by Chaos Bolt until Witch Doctor buys Glimmer Cape or Black King Bar.

* Heroes who have channeling abilities because Terrorblade has no disables to cancel them at all and does not like buying disabling items at all: Enigma's Black Hole, Witch Doctor's Death Ward, Shadow Shaman's Shackles, Lion's Mana Drain, Bane's Fiend's Grip, Pudge's Dismember, Crystal Maiden's Freezing Field, Pugna's Life Drain, Dawnbreaker's Solar Guardian, and Naga Siren's Reel In from Aghanim's Scepter.

* 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.

* Terrorblade cannot go one on one against Troll Warlord as Troll Warlord will overwhelm him faster than the other way around thanks to Whirling Axes (Melee) that will cause his attacks to miss, and Fervor that can give Troll Warlord huge amounts of attack speed to outmatch Terrorblade, even during Metamorphosis.
* Troll Warlord's high attack speed from Fervor combined with Skull Basher and Abyssal Blade means that Terrorblade will have almost no chance to use Sunder to save himself.
* Even if Terroblade manages to use Sunder on Troll Warlord, Troll Warlord will simply be able to nullify it's effect with Battle Trance.
* Overall, any attempt for Terrorblade to engage and kill Troll Warlord will hurt him more than the other way around.

* Arcane Bolt can target Terrorblade's low health pool in the laning phase.
* Ancient Seal can prevent Terrorblade from casting Sunder.
* Mystic Flare can be used to great effect to burst Terrorblade down before he gets a Manta Style or a Black King Bar.

* 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).

* If carefully timed, Aghanim's Scepter upgraded Eclipse combined with 0.2s Eclipse Lucent Ministun talent can quickly finish off Terrorblade before he can get a chance to save himself with Sunder due to its high magical damage as long as Terrorblade has no Black King Bar.
* Moon Glaives allows Luna to clear Terrorblade's illusions from both, Conjure Image and Manta Style, this can be particularly advantegous for Luna if she has Manta Style. Just bear in mind, however, that Reflection can be used to turn Moon Glaives against Luna during laning phase.
* Luna very often builds Satanic and Black King Bar, which allows it either to protect herself from Sunder or nullify it's effects.

* Luna very often bulds Satanic and Black King Bar as well as it's alternative item Linken's Sphere, which allows her either to protect herself from Sunder or nullify it's effects.

* All of Shadow Shaman's abilities totally ruin Terrorblade: Ether Shock destroys his illusions, Hex prevents him from using Sunder or Manta Style in bad situations, Shackles not only that prevent him from using Sunder, but he has no way to cancel it and Mass Serpent Ward can help Shadow Shaman push faster than Terrorblade even in Metamorphosis.
Additional:
* Ether Shock, Mass Serpent Wards summoned from both, Mass Serpent Ward and Aghanim's Shard upgraded Shackles can do great damage to both, Terrorblade and his illusions.
* Hex prevents Terrorblade from using Sunder or Manta Style in bad situations. Hex can also destroy one of his illusions.
* Shackles can damage Terrorblade and prevent him from using his abilities and items, whether to fight, survive, or dispel it in any way while also healing Shadow Shaman in process. In addition, Terrorblade has no solutions to cancel it. Aghanim's Shard upgraded Shackles can also summon four more Mass Serpent Wards to attack Terrorblade while he is disabled.

* Quill Spray quickly destroys Chaos Knight's Phantasms.
