Morphling
* 
Necrophos's 
Reaper's Scythe can finish off a low-health Morphling.
Centaur Warrunner
* 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.
Additional:
* With high health and rarely buying 
Linken's Sphere or 
Black King Bar, Centaur Warrunner is a good target for Reaper's Scythe. However, Centaur Warrunner can resolve this problem by buying 
Hood of Defiance and it's upgrade 
Pipe of Insight to diminish its damage.
* 
Heartstopper Aura will do well against high health heroes such as Centaur Warrunner.
Morphling
* 
Earthbind disables Waveform, effectively keeping Morphling in place for an extended period of time, allowing Meepo to deal considerable damage with 
Poof.
Centaur Warrunner
* 
X Marks the Spot negates Stampede.
Morphling
* Most of Morphling's armor comes from his high agility and it is reduced by 
Natural Order.
* However, the aura has only 350 range and Elder Titan can be bursted down by Morphling's nuke combo if he isn't careful.
Additional:
* Morphling's high armor is primarily from morphing agility, which is reduced by Natural Order therefore making the hero very vulnerable when it has morphed a lot into agility.
* Morphling usually will Morph into high agility and low strength. This can be taken advantage of with a good stun or silence or by bursting him down before he has the time to Morph back to strength.
* Morphling is very vulnerable to 
Blade Mail under Natural Order and can easily burst himself down with his own auto-attacks or his magical damage combo.
Morphling
* 
Arcane Orb deals pure damage, effectively bypassing Morphling's high armor from Attribute Shift (Agility Gain).
* 
Sanity's Eclipse is more effective against a low health and mana pool Morphling, enabling Outworld Destroyer to burst Morphling down before he can shift to Strength.
Additional:
* Arcane Orb deals high damage regardless of Morphling's high armor from 
Attribute Shift (Agility Gain).
* Because of Morphling's very low intelligence gain and base intelligence, Sanity's Eclipse will almost always be effective against Morphling.
Centaur Warrunner
* Luna's 
Moon Glaives will not trigger 
Retaliate if they hit some other target first. Also Luna commonly buys items that provide lifesteal such as 
Satanic, which lets her heal from the damage of Retaliate, meaning that Retaliate has limited effect against her.
* 
Eclipse can be used to counter-initiate against Centaur Warrunner after he jumps in with 
Blink Dagger, and initiates with 
Hoof Stomp. But remember that Centaur Warrunner can resolve this problem by buying Hood of Defiance and it's upgrade Pipe of Insight to diminish its damage. Or Blade Mail to reflect the damage of the Eclipse back at Luna.
* Luna also commonly buys Black King Bar, which will allow her to protect herself from both, Centaur Warrunner's abilities (except for the Retaliate), and damage reflect from Blade Mail.
Additional:
* Luna's Moon Glaives will not trigger Retaliate if they hit some other target first. Also Luna commonly buys items that provide lifesteal such as Satanic, which lets her heal from the damage of Retaliate, meaning that Retaliate has little effect against her.
* Eclipse can be used to counter-initiate against Centaur Warrunner after he jumps in with Blink Dagger, and initiates with Hoof Stomp. But remember that Centaur Warrunner can resolve this problem by buying Hood of Defiance and it's upgrade Pipe of Insight to diminish its damage. Or Blade Mail to reflect the damage of the Eclipse back at Luna.
* Luna also commonly buys Black King Bar, which will allow her to protect herself from both, Centaur Warrunner's abilities (except for the Retaliate), and damage reflect from Blade Mail.
Morphling
* 
Ice Blast stops Attribute Shift (Strength Gain) from recovering adional health, and using it will even bring Morphling closer to the shatter threshold.
* In lane, 
Ice Vortex slows Morphling's already poor movement speed to a crawl; this, coupled with the amplification of magic damage, can set up an early kill on Morphling if Ancient Apparition has a suitable lane partner.
Additional:
* Ice Blast stops Morphling from gaining additional health with 
Attribute Shift.
* Using Attribute Shift would even bring Morphling closer to the shatter threshold.
* In the lane, Ice Vortex slows Morphling's already poor movement speed to a crawl; this, coupled with the amplification of magic damage, can set up an early kill on Morphling if Ancient Apparition has a suitable lane partner.
Centaur Warrunner
* Decay can be good against Centaur Warrunner, as reducing the health of Centaur can make 
Double Edge risky.
* His zombies do not proc Retaliate, as it only procs for regular attacks.
Morphling
* 
Arcane Bolt's low cooldown allows him to deal consistent damage to Morphling, and is a viable way to disable Linken's Sphere.
* 
Ancient Seal prevents Morphling from using any of his skills, giving Skywrath Mage and his team ample time to burst Morphling down.
* 
Mystic Flare coupled with a stun/root can easily burst Morphling down, especially if he has more stats shifted to Agility.
* Alternatively, Morphling can use Morph to use Skywrath Mage's own silence and nukes against him.
Morphling
* Jumping on Axe with 
Waveform will make Morphling an easy target for a counter-initiation with Berserker's Call.
* Morphling is often played at low health to maximize the bonuses from Attribute Shift (Agility Gain), and also because his abilities cost health to use. This makes him especially vulnerable to Culling Blade.
* However, Morphling is a common Linken's Sphere carrier to block Culling Blade, which may force Axe to use Battle Hunger to pop the Spell Block first.
* Attribute Shift (Agility Gain) gives Morphling no protection against the pure damage of Culling Blade. Its attack speed bonus also means that Counter Helix will proc more often.
Morphling
* 
Sharpshooter can kill easy when Morphling is going on full agility strategy (Only in early and mid game).
* 
Scurry can help to catch up Morphling when using Waveform or for escape.
Centaur Warrunner
* 
Kinetic Field and 
Glimpse can completely negate Stampede.
Morphling
* 
Geomagnetic Grip is not blocked by Linken's Sphere and can silence Morphling, preventing Morphling from using Waveform or Attribute Shift to escape from ganks.
* In addition, 
Boulder Smash and 
Rolling Boulder provide a solid lockdown if used together.
Centaur Warrunner
* Centaur has nothing to deal with 
Refraction that will negate all of his burst damage.
* 
Psionic Traps provide good vision, making for him harder to initiate.
Morphling
* 
Sacred Arrow's long stun duration can prevent Morphling from casting his Waveform or Morph Replicate, making him unable to escape and easier to gank.
* 
Moonlight Shadow also allows Mirana's team to surprise Morphling while he tries to push towers.
* Mirana usually buys Linken's Sphere to protect herself from single-target abilities, making Morphling's Adaptive Strike and 
Ethereal Blade harder to use on her.
* However, Mirana also provides a chance to become a good Morph target, allowing Morph to use 
Leap to run away, if necessary.
Morphling
* 
Mana Drain rapidly saps Morphling's already low mana pool, making him unable to use Waveform or Adaptive Strike. Additionally, 
Hex prevents these abilities as well.
* An 
Earth Spike and 
Finger of Death combo can burst an unwary Morphling down if he has his strength fully shifted to agility.
Morphling
* Morphling usually has low max health due to shifting strength into agility, which combined with Blast Off's silence will prevent him from using Waveform and 
Adaptive Strike (Strength), leaving him defenseless and making him an easy target to burst down.
Morphling
* Rubick's ability to steal Attribute Shift (Strength Gain) makes him extremely annoying to deal with because Rubick's shifted attributes will remain even if he steals a new spell.
* If Rubick moves enough points to strength and then steals Adaptive Strike, he will have a powerful 3-second ranged stun in his arsenal as well.
* Waveform provides a reliable nuke/escape to Rubick.
* Rubick can steal most abilities Morphling uses while Morphed, allowing Rubick to steal his own allies' abilities if the Morphling is not careful.
Additional:
* 
Morphling's abilities can grant unrivaled utility for 
Rubick.
* 
Attribute Shift (Strength Gain) is a great spell that has a longlasting effect, since the attribute change is permanent even after losing the ability. By casting the spell, Rubick becomes significantly tanky after pumping all his agility into strength.
* As the cost of the shift, Rubick's attack speed as well as his armor is hindered. Since the right click damage of Rubick is relatively trival in teamfights, armor items such as 
Medallion of Courage or 
Buckler could greatly increase Rubick's effective health to physical damage.
* Rubick must be careful not to confuse Attribute Shift (Strength Gain) with Attribute Shift (Agility Gain).
* Adaptive Strike (Strength) is a long-ranged stun.
* If Attribute Shift (Strength Gain) has been stolen and cast, the spell can stun the enemy for 3 seconds. The stun counters mobile heroes such as Morphling.
* Waveform is a damaging pseudo-blink, giving Rubick much needed mobility and farming potential.
Morphling
* Jakiro's early pushing ability from Liquid Fire makes Jakiro very strong against heroes, that take a long time to get online: Morphling, 
Naga Siren, 
Spectre.
Morphling
* Low-health, normally mobile carries who rely entirely on raw attack damage are vulnerable to Bane's nukes and disables: 
Anti-Mage, 
Clinkz, 
Drow Ranger, 
Faceless Void, 
Gyrocopter, 
Juggernaut, 
Meepo, 
Mirana, 
Monkey King, Morphling, 
Phantom Assassin, 
Phantom Lancer, 
Riki, 
Shadow Fiend, 
Slark, 
Sniper, 
Terrorblade, 
Troll Warlord, 
Weaver.
Morphling
* Heroes with silencing abilities that are not blocked by Linken's Sphere, like 
Puck's 
Waning Rift, 
Death Prophet's 
Silence or 
Silencer's 
Global Silence.
Morphling
* Heroes with high damage output who can burst down Morphling before he has time to use Attribute Shift (Strength Gain), like 
Lina and 
Lion.
Additional:
* Light Strike Array catches Morphling while he jumps in from Waveform and also prevents Morphling from using his abilities.
* Laguna Blade can kill Morphling quickly before he shifts into Attribute Shift (Strength Gain).
Morphling
* Heroes with blink or movement abilities, which are disabled by Pounce's leash: Anti-Mage, 
Earth Spirit, Faceless Void, Magnus, Mirana, Monkey King, Morphling, 
Pangolier, Phantom Assassin, 
Phoenix, Puck, 
Queen of Pain, Riki, 
Sand King, 
Spirit Breaker, 
Timbersaw, 
Tusk.
Morphling
* 
Underlord's 
Atrophy Aura reduces Morphling's high base damage gained through agility shift.
Morphling
* 
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.
Centaur Warrunner
* 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.
Morphling
* Time Dilation affects Morphling's low cooldown spells, making them unusable for a long time, rendering Morphling nearly useless.
* Morphling cannot use Attribute Shift while he is inside Chronosphere which makes it easy to kill him.
Centaur Warrunner
* Heroes that can stop Faceless Void from leaping around the fight and controlling its outcome are very strong against him. Heroes such as: 
Axe, Centaur Warrunner, 
Doom...
Morphling
* Void Spirit can greatly pressure Morphling's farm, which is very bad for a hero who needs a large amount of space.
* Waveform does not provide better mobility than Astral Step.
* If Morphling shifted all of his strength to agility, he can be bursted down by Void Spirit before he can react.
* Doing an Ethereal Blade combo on Void Spirit is incredibly difficult, as Dissimilate and Astral Step can allow him to escape or dodge the projectile.
Centaur Warrunner
* Heroes who can match Void Spirit's mobility (like the aforementioned 
Ember Spirit or Queen of Pain) or tank his spells (
Dragon Knight or Centaur Warrunner) are very problematic for him.
Morphling
* Morphling's naturally high armor thanks to his high agility makes it hard for Phantom Assassin to take him down with 
Coup de Grace.
Centaur Warrunner
* Hoof Stomp and Double Edge can often burst down Phantom Assassin from early to mid game.
* Retaliate makes it very unlikely for Phantom Assassin to win the lane against Warrunner. Double Edge can also be used to wear her down, as she has a much smaller health pool than that of Centaur Warrunner until purchasing a 
Ring of Health. 
Stifling Dagger will also trigger Retaliate and 
Blur cannot evade Retaliate.
* Centaur Warrunner's tankiness in combination with armour items that Centaur Warrunner often purchases like Blade Mail, 
Crimson Guard, 
Assault Cuirass and 
Shiva's Guard can make Phantom Assassin's attacks only tickle Centaur Warrunner.
* Centaur Warrunner just has to be careful about 
Fan of Knives from 
Aghanim's Shard and Coup De Grace, as Fan of Knives can disable Retaliate even if Centaur Warrunner is spell immune.
Additional:
* Hoof Stomp and Double Edge can often burst down Phantom Assassin from early to mid game.
* Retaliate makes it very unlikely for Phantom Assassin to win the lane against Warrunner. Double Edge can also be used to wear her down, as she has a much smaller health pool than that of Centaur Warrunner until purchasing a Ring of Health. Stifling Dagger will also trigger Retaliate and Blur cannot evade Retaliate.
* Centaur Warrunner's tankiness in combination with armour items that Axe often purchases like Blade Mail, Crimson Guard, Assault Cuirass and Shiva's Guard can make Phantom Assassin's attacks only tickle Centaur Warrunner.
* Centaur Warrunner just has to be careful about Fan of Knives from Aghanim's Shard and Coup De Grace, as Fan of Knives can disable Retaliate even if Centaur Warrunner is spell immune.
Morphling
* Morphling can break 
Static Link with Waveform. Alternatively, Morphling can Morph into Razor and use the same ability against him.
* Morphling's high armor makes 
Eye Of The Storm mostly ineffective, enabling Morphling to fight Razor for longer.
* Razor has no disables, enabling Morphling to avoid his abilities as needed.
Additional:
* Static Link is almost completely useless against Morphling, as he is able to quickly break it off with Waveform or turn into Razor himself with 
Morph and recover all of his stolen damage, or simply steal Razor's own.
Centaur Warrunner
* Centaur can use 
Stampede to break Static Link. It also prevents Razor from chasing Centaur Warruner or his teammates with Eye of the Storm, and Plasma Field's slow will do nothing to slow them down.
Morphling
* All abilities for Morphling can easily escape fear 
Focus Fire.
* Windranger weakness for agility can easily Morphling destroy against her.
Additional:
* Waveform can be used to escape from the reach of Focus Fire and to dodge 
Powershot.
* Adaptive Strike (Strength) can be used to stun Windranger even while 
Windrun is active.
* Morph is useful to morph into Windranger to copy her abilities.
Centaur Warrunner
* Stampede can help his teammates escape from Windrun and Focus Fire.
* Retaliate will shred through Windranger's health if she chooses to attack him during Focus Fire.
Additional:
* Focus Fire grants Windranger a massive attack speed bonus, while her attack damage is generally quite low. This, combined with Windranger's low health pool and armor, makes Retaliate do absolutely massive damage over a short time, making Centaur a hero she can never expect to kill or harass.
* Windrun grants evasion, but Centaur Warrunner does not rely on successful attacks in order to do damage. Hoof Stomp, Double Edge, and Stampede all do large amounts of magical damage and can completely demolish Windranger in a moment.
Morphling
* Waveform clear Mirror Image illusions from Naga Siren. And though 
Ensnare can prevent Morphling from using Waveform to escape, he can easily dispel it with Manta Style, a common item on Morphling.
* Morph allows Morphling to copy Naga Siren's abilities and combine them with Manta Style, a commong item for Morphling, to destroy Naga Siren's illusions. 
Aghanim's Scepter upgraded Morph also allows Morphling to create a strong illusion of Naga Siren that can do the same and which can also allow Morphling to close the gap on Naga Siren.
Centaur Warrunner
* Centaur's Retaliate will harm all attacking enemies, which will allow Centaur Warrunner to see which is the real Naga Siren.
* A well timed Hoof Stomp followed by Double Edge will clear all Naga's illusions and prevent Naga Siren from escaping with 
Song of the Siren.
Morphling
* Heroes who often build Linken's Sphere: Weaver, Morphling, 
Medusa.
Centaur Warrunner
* Stampede can be used to free an ally from the grasp of Doom. Without any means of effective lockdown, kills can be difficult to secure when against an enemy Centaur Warrunner. Also, Centaur's tendency to have lots of health and HP regen tend to help counter Doom.
Additional:
* Whenever Doom casts his ultimate, Centaur Warrunner can cast Stampede and allow the 
Doomed hero to run away, wasting Doom's ultimate.
Morphling
* Morphling's high mobility allows him to easily get close to Sniper, who likes to keep his distance from enemies.
Centaur Warrunner
* Heroes who have high health are a problem for Sniper because he likes to attack the closest target and sit at the back, much like a Terrorblade so when that hero doesn't die; he's forced to show his position for a very long time: Centaur Warrunner, 
Legion Commander, 
Primal Beast.
Additional:
* 
Headshot and 
Shrapnel slow is ineffective against a team with haste (which Stampede gives).
* Commonly picked up mobility items and hasted movement during his Stampede (as well as his high health pool) make him extremely hard to kill from a distance, damaging Sniper with Retaliate and Blade Mail if he has one.
* A low health pool and no escape mechanism makes him an easy target for Centaur Warrunner's burst damage and initiation (even making his team possible initiators with Stampede).
Morphling
* Heroes with mobility spells can quickly escape from Stroke of Fate or break out of Soulbind: Anti-Mage, Queen of Pain, Morphling, 
Storm Spirit
Centaur Warrunner
* Stampede can allow Soulbinded heroes to just ran away.
Morphling
* Heroes who can take advantage of God's Strength being on cooldown are also not great matchups, such as 
Templar Assassin, Morphling and 
Huskar.
Centaur Warrunner
* Heroes who thrive on teamfights can be a problem, such as 
Venomancer, Necrophos, Centaur Warrunner...
Centaur Warrunner
* Pangolier will proc Retaliate several times if he attempts to use 
Swashbuckle on Centaur Warrunner.
* Centaur can cast Stampede to allow all of his allies to easily avoid 
Rolling Thunder.
* Centaur's tankiness makes it hard for Pangolier to burst him down in the late game.
Additional:
* When Swashbuckle hits Centaur Warrunner, Retaliate will deal significant damage, as it procs off every strike made.
* Stampede helps allies avoid or disengage from Pangolier during Rolling Thunder, as well as neutralizing the slow debuff from Lucky Shot.
Centaur Warrunner
* A good Centaur can catch Queen of Pain with a Blink Dagger and Hoof Stomp.
* Retaliate with Blade Mail reflects all of Queen of Pain's damage, especially Sonic Wave.
* Stampede grants a movement speed bonus, which can prevent Queen of Pain from initiating.
* Double Edge can shred her low health pool if she's not careful.
Morphling
* Waveform ignores Rupture's damage, letting Morphling escape unharmed.
* Attribute Shift (Strength Gain) makes it very hard for Bloodseeker to kill Morphling or gain his Thirst bonuses, since Morphling can use it to sustain damage while trading attacks when Ruptured.
* Morphling usually builds Linken's Sphere, which blocks Rupture.
Additional:
* Morphling can escape from 
Rupture using Waveform.
* Morphling is a typical Manta Style carrier, which can be used to dispel the silence from 
Blood Rite.
Morphling
* Morph allows Morphling to copy abilities of Spirit Breaker and combine them with Waveform to turn things around. Aghanim's Scepter upgraded Morph also allows Morphling to create a strong illusion of Spirit Breaker that can cast all of his basic abilities. This allows Morphling to give Spirit Breaker a taste of his own medicine.
* Spirit Breaker's low attack speed and lack of burst damage makes it unlikely for him to win against Morphling when he has Attribute Shift (Strength Gain) toggled on.
Morphling
* Viper has no disable, which means he has no way of preventing Morphling from escaping from any of his abilities or keep him inside 
Nethertoxin.
* Viper is almost exclusively damage over time, which is weak against Morphling due to Attribute Shift (Strength Gain). Additionally, Morphling has no passive abilities, reducing Nethertoxin's effectiveness against him even further.
* Morphling can turn into Viper himself, allowing him to use any of Viper's abilities against him (excluding 
Viper Strike). This is particularly bad due to the fact that Viper is already a very slow hero, making 
Poison Attack and 
Corrosive Skin's slows especially difficult to deal with.
Centaur Warrunner
* Centaur's low Intelligence makes 
Mind Flare do low damage.
* With some creative skill builds, Centaur's Hoof Stomp stun duration should always last longer than 
Spiked Carapace stun, so escaping unscathed is hard for Nyx.
* With Blink Dagger and detection, Centaur can devastate Nyx in the open.
* However, bear in mind that Nyx can also easily initiate on Centaur Warrunner as well if he uses Spiked Carapace in anticipation, and with 
Vendetta. The damage from Retaliate will be reflected back to Centaur Warrunner, stunning him with no chance to react after he's revealed himself, and should guarantee a successful 
Impale.
Morphling
* Waveform allows Morphling to escape from Mass Serpent Ward
* Morphling can interrupt Shadow Shaman while he is shackling an ally with Adaptive Strike (Strength).
* With Ethereal Blade Morphling can quickly burst him down before he even has a chance to react.
Morphling
* Morphling can Attribute Shift to strength after being hit by Maledict. Since Maledict deals its damage based on the difference between HP on cast and HP after two seconds, odds are Morphling will have more HP than when Maledict was cast, thus resulting in no damage.
* On the upside, players prone to panicked reactions may Morph to agility, making Maledict even more efficient than intended.
* Adaptive Strike (Strength) can interrupt Death Ward at a decent range.
Morphling
* By using Morph, Morphling can use Burning Barrage and Searing Arrows to counter Clinkz himself.
* Waveform can allow Morphling to easily chase down Clinkz.
* Clinkz's low health pool also makes him vulnerable to Morphling's magical nukes, especially his Ethereal Blade and 
Adaptive Strike combo.
Centaur Warrunner
* Centaur Warrunner's passive Retaliate makes it so that the familiars cannot attack him without damaging themselves over time, in turn causing them to be destroyed.
Centaur Warrunner
* Heroes with haste can negate Enchant's slow: Weaver, 
Dark Seer, 
Lycan, Centaur Warrunner.
Morphling
* Heroes with high base damage (Morphling, 
Tiny, Drow Ranger), heroes with mana burning abilities (Anti-Mage), and 
Diffusal Blade users (Juggernaut or Riki) will suffer from Reflection's illusions.
Morphling
* 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.
Centaur Warrunner
* As Terrorblade's damage output comes mainly from direct attacks, he will struggle greatly against heroes who have abilities that give evasion, trigger on attack or which can disarm an enemy hero: Centaur Warrunner, 
Hoodwink, Huskar, Invoker, 
Leshrac with 
Nihilism from Aghanim's Scepter, 
Lifestealer with Aghanim's Scepter upgraded 
Infest, Pangolier, Phantom Assassin, 
Pugna, 
Techies, 
Windranger etc.
Morphling
* Heroes with Linken's Sphere as core item: Weaver, Morphling, Medusa.
Centaur Warrunner
* Durable heroes can stand against Tusk during 1v1: Axe, Dragon Knight, 
Night Stalker, Centaur Warrunner, 
Wraith King and more.
Centaur Warrunner
* Heroes that can keep Monkey King stunned for a long time can pose a threat: Axe, Centaur Warrunner.
Morphling
* Attribute Shift (Strength Gain) may not be quick enough to fend off an attacking Drow Ranger.
* Morphling likes to sit on low health with high agility, something Drow Ranger does not particularly care for and will still hit him hard with Marksmanship procs.
* Morph is a similar story, none of Drow Ranger's spells are particularly good against her.
Morphling
* Morphling can use Waveform to close the gap between him and Drow Ranger, but should be careful of 
Gust and 
Frost Arrows.
* Morphling is a natural Manta Style carrier, which dispels the silence from Gust.
Centaur Warrunner
* Heroes who have low or high armor but very high health will be difficult for drow to burst down quickly: Primal Beast, Axe, Centaur Warrunner.
Morphling
* Heroes with high mobility will be able to avoid Gyrocopter's area attacks: Storm Spirit, Morphling, Ember Spirit
Centaur Warrunner
* Heroes that are hard to gank: Dragon Knight, 
Mars, Centaur Warrunner.
Centaur Warrunner
* Heroes who are reliant on illusions: Chaos Knight, Phantom Lancer, Naga Siren.
Morphling
* Arc Warden can counter Morphling's strong pushing capabilities by using 
Magnetic Field to protect buildings.
* Arc Warden also often builds an 
Orchid Malevolence or 
Bloodthorn, which can prove dangerous for Morphling.
* Arc Warden can easily break Linken's Sphere with 
Flux and then slow him with 
Spark Wraith, making Arc Warden's 
Tempest Double a legitimate threat as well.
Morphling
* Heroes with good escape mechanisms are a nuisance to deal with in the early phase of the game: Slark, Lifestealer, Morphling
Centaur Warrunner
* Arc Warden cannot take Centaur Warrunner very easily, and his nukes are not strong enough to deal with Centaur Warrunner.
* Centaur Warrunner deals huge AoE damage and applies an AoE disable through Hoof Stomp, affecting the double as well the main Arc Warden.
* Magnetic Field is not very effective against melee heroes. And to make things worse, Magnetic Field also increases Arc Warden and his allies's attack speed, meaning Retaliate will deal more damage.
* Stampede catches Arc Warden easily due to his lack of escape mechanisms. However, Arc Warden can counter this problem with 
Gleipnir, which is a common item on Arc Warden.
Centaur Warrunner
* Heroes with long cast animations can be continuously interrupted by Battery Assault: Centaur Warrunner, 
Jakiro, Leshrac, Naga Siren, Underlord.
Additional:
* 
Battery Assault easily interrupts Centaur Warrunner due to his poor cast animation.
* 
Power Cogs can negate Stampede.
Morphling
* Morphling can escape from Power Cogs with Waveform.
* Even if Morphling is trapped in Power Cogs, Morphling can use Attribute Shift (Strength Gain) to survive the duration.
Additional:
* Waveform allows Morphling to easily escape Power Cogs.
* Clockwerk's lack of burst damage makes it nearly impossible for him to kill a Morphling using Attribute Shift (Strength Gain).
Morphling
* Heroes who just want to farm and avoid Lone Druid early will find it very hard to do so when he starts knocking on towers: Templar Assassin, Phantom Assassin, Ember Spirit, Morphling.
Morphling
* Morphling can ignore Spirit Bear and shorten the distance to Lone Druid with Waveform.
* Morphling can use his nukes to burst Lone Druid down, provided he is not rooted/disabled by Spirit Bear beforehand.
Morphling
* Heroes with silencing abilities that are not blocked by Linken's Sphere, like Puck's Waning Rift, Death Prophet's Silence or Silencer's Global Silence.
Centaur Warrunner
* Axe, 
Bristleback, Centaur Warrunner, Spirit Breaker, 
Pudge, Huskar, Wraith King: These heroes are too tanky for Puck to burst down. Also, all of them have spells which can deal with and shut Puck down reliably.
Morphling
* Heroes with silencing abilities that are not blocked by Linken's Sphere, like Puck's Waning Rift, Death Prophet's Silence or Silencer's Global Silence.
Additional:
* While Morphling can burst her down with 
Adaptive Strike (Agility), Death Prophet does have tools to disrupt him. A Morphling affected by Silence makes it unable to use Attribute Shift (Strength Gain) to increase its health pool or use Waveform to escape.
Morphling
* Heroes that can kill Death Prophet with nukes can prevent her from using Exorcism to its full duration or using it at all: Lina, Lion, Puck, Morphling.
Centaur Warrunner
* Centaur Warrunner's active abilities cannot pierce magic immunity. Hoof Stomp's slow wind up can also be anticipated and negated with Rage.
* Lifestealer can offset Retaliate's damage return simply with Feast. Centaur's high strength gain and therefore big health pool makes him an ideal target to Feast on, especially in the late-game.
Additional:
* 
Feast is an effective tool against Centaur Warrunner, who generally has high health and low armor, and compensates the reflected damage of Retaliate.
* If activated, 
Rage can protect Lifestealer from Hoof Stomp, Double Edge, and Stampede.
Morphling
* Lifestealer is a great target for Morphling to use Morph, as he can use Rage to gain spell immunity and a movement speed boost.
* Morphling's high armor also makes Lifestealer's attacks do less damage.
Morphling
* Phantom Lancer can effortlessly overwhelm Morphling with a large number of illusions. It becomes even more effective with {Item ID:Diffusal Blade}, which takes away his mana in the process.
* 
Doppelganger can be used to dodge Adaptive Strike combo and create confusion with two additional illusions.
* 
Eye of Skadi can be bought to slow and negate the health regeneration from Attribute Shift, and a common item for Phantom Lancer.
Centaur Warrunner
* Hoof Stomp and Double Edge makes short work of Phantom Lancer's illusions.
* Retaliate together with Blade Mail reflects Phanton Lancer's damage and quickly destroys his illusions.
Additional:
* His illusions will kill themselves in a few hits because of Retaliate. The nukes from Hoof Stomp and Double-Edge should be enough to clear them for a large portion of the game
* Centaur Warrunner's small mana pool makes Diffusal Blade's damage much lower once Centaur doesn't have any more mana left to burn. Keep in mind that Double Edge does not cost mana.
* Be wary when chasing down Phantom Lancer. Hoof Stomp's terrible cast time makes it quite easy to dodge with Doppelganger.
Morphling
* Heroes that rely on right-clicks will find that their attacks will miss a lot, due to Whirling Axes (Melee)'s miss chance. Such heroes include Phantom Assassin, Terrorblade, and Morphling.
Centaur Warrunner
* Troll Warlord's high speed attack makes Retaliate deal a lot of damage to him.
Morphling
*
Winter Wyvern's 
Winter's Curse turns Morphling's high attack damage and attack speed against his targeted teammate.
Centaur Warrunner
*
Winter Wyvern's 
Arctic Burn can also be a useful tool against Centaur, who generally has very high health. 
Winter's Curse on Centaur can cause Retaliate to damage allies who are forced to attack him.
