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.
Dazzle
* 
Astral Imprisonment is a versatile nuisance:
* If it is cast on a low-enough-health unit at least 1 second into Shallow Grave's duration, the Shallow Grave will end during the imprisonment, and the target will take lethal damage when released.
* It can be used remove Dazzle from the fight at a time he could have saved someone.
* It lets himself or an ally dodge all of Poison Touch's effects, for long enough to recover their 
Blink Dagger.
Morphling
* 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.
Additional:
* 
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.
Dazzle
* 
Shallow Grave prevents Ice Blast's shatter for up to 5 seconds, but can mostly only delay it as Ice Blast's debuff lasts 10 seconds and prevents 
Shadow Wave from healing them.
Additional:
* Ice Blast negates healing from Shadow Wave, and lasts longer than Shallow Grave.
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.
Dazzle
* Although Counterspell's passive component doesn't protect Anti-Mage from the physical damage nukes from Poison Touch and Shadow Wave, a well-timed use of it will reflect Poison Touch back to Dazzle, slowing him in the process.
* This can be even more dangerous if Dazzle has an 
Aghanim's Shard, as Counterspell will reflect the hex back to Dazzle.
* Mana Break drains mana, which can be a problem for Dazzle, as all of his abilities have a high mana cost. This makes him especially vulnerable to 
Mana Void.
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.
Dazzle
* 
Juxtapose and Doppelganger conjures too many illusions for Dazzle to deal with, given he has no inherent movement- or AoE-abilities.
* However, this can be partially solved with Aghanim's Shard-upgraded Poison Touch, as the hex instantly destroys illusions in an area as well as revealing the real Phantom Lancer when he's hiding among his army of illusions.
* 
Phantom Rush and 
Spirit Lance allow Phantom Lancer to trivially catch Dazzle even in the back line of a fight.
* Phantom Lancer has high base armor which counters Dazzle's physical damage based spells in lane.
* 
Diffusal Blade a natural item from Phantom Lancer can drains mana, which can be a problem for Dazzle, as all of his abilities have a high mana cost.
Morphling
* 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).
Dazzle
* Heroes with high burst damage through their physical attacks or spells can kill Dazzle or his allies before he has a chance to use Shallow Grave. (
Lina, 
Lion, etc.)
Additional:
* Laguna Blade can kill Dazzle quickly before he casts Shallow Grave.
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.
Dazzle
* A well-timed Global Silence prevents Dazzle from saving allies with Shallow Grave or Shadow Wave. Items that could dispel the silence are expensive, and difficult for Dazzle to farm from a support role.
* 
Arcane Curse and 
Last Word cause long damage over time, which may outlast Shallow Grave.
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.
Dazzle
* Heroes with high burst damage through their physical attacks or spells can kill Dazzle or his allies before he has a chance to use Shallow Grave. (Lina, Lion, etc.)
Morphling
* 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.
Additional:
* 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.
Morphling
* 
Earthbind disables Waveform, effectively keeping Morphling in place for an extended period of time, allowing Meepo to deal considerable damage with 
Poof.
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.
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
* 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.
Dazzle
* Pugna can turn out to be an effective hero against Dazzle due to the fact that he does not allow him to extend his 
Poison Touch with his 
Decrepify, which is why Dazzle cannot keep the enemy under prolonged deceleration.
* Pugna has a very strong ability against casters with a small health reserve - 
Nether Ward, which is why heroes like Dazzle will not be able to constantly throw their Poison Touch 
Bad Juju and Shadow Wave at enemies under the action of Nether Ward or will be forced to take a lot of damage
Additional:

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
* 
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.
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
* 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
* 
Underlord's 
Atrophy Aura reduces Morphling's high base damage gained through agility shift.
Morphling
* 
Winter Wyvern's 
Winter's Curse turns Morphling's high attack damage and attack speed against his targeted teammate.
Dazzle
* Support heroes with low mobility can be slowed further by Incapacitating Bite, and swarmed by Spiderlings for an easy kill: 
Shadow Shaman, 
Visage, 
Dazzle, Rubick, 
Lich.
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.
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.
Dazzle
* Spectre's entire ability set is designed to get to and destroy heroes that stay in the backlines, both carries (like the aforementioned 
Drow Ranger and 
Sniper) and supports (like Dazzle and Shadow Shaman).
Dazzle
* Some heroes with extreme range, like 
Zeus, 
Invoker or 
Clockwerk, can snipe your allies from anywhere after your Grave has expired.
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.
Dazzle
* Some heroes with extreme range, like Zeus, Invoker or Clockwerk, can snipe your allies from anywhere after your Grave has expired.
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
Morphling
* 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.
Dazzle
* Doom can completely shut down Dazzle through 
Doom, as it prevents him from casting his abilities and, by extension, gaining Bad Juju stacks.
Morphling
* Heroes who often build Linken's Sphere: 
Weaver, Morphling, 
Medusa.
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.
Dazzle
* Heroes that can slow Charge of Darkness by a huge amount: 
Venomancer, 
Viper, Dazzle, 
Arc Warden, Lion, 
Huskar, Shadow Shaman, Visage, 
Undying, 
Jakiro.
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.
Dazzle
* Heroes that excel at grouping up with their team very early will be able to take advantage of a Clinkz that tries to pick off heroes that are alone: 
Brewmaster, Dazzle, 
Tidehunter.
Dazzle
* Some heroes with extreme range, like Zeus, Invoker or Clockwerk, can snipe your allies from anywhere after your Grave has expired.
Morphling
* 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).
Additional:
* 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.
Dazzle
* Aghanim's Shard upgraded Poison Touch can be used to hex Clockwerk, silencing him, disarming him, slowing him, and muting him, and thus rendering him unable to use Blade Mail to return damage or to do anything at all.
* Shadow Wave will hit Clockwerk every time when he's fighting with an enemy inside Power Cogs.
* Due to Clockwerk's very low damage output, Dazzle will have more than enough time to Shallow Grave any enemy hero Clockwerk initiates on.
Additional:
* Shadow Wave will hit Clockwerk every time when he's fighting with an enemy inside Power Cogs.
* Due to Clockwerk's steady damage output, Dazzle has plenty of time to Shallow Grave anyone Clockwerk initiates on.
Dazzle
* 
Bloodseeker's 
Thirst, 
Rupture, and huge AoE silence 
Blood Rite can fare well against Dazzle.
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.
Dazzle
* Shallow Grave prevents Bloodseeker from replenishing his health by finishing off enemies.
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.
Dazzle
* Dazzle easily breaks the position of Lone Druid and his 
Summon Spirit Bear with his Poison Touch, As it always hits from afar and prolongs the slowdown on the Summon Spirit Bear, which is why he cannot catch up with Dazzle and treat his master with 
Spirit Link
* Dazzle helps his team survive the physical attacks of the Summon Spirit Bear thanks to the treatment from Shadow Wave and armor from Bad Juju, which can enable his team to kill Lone Druid
* The Lone Druid Summon Spirit Bear has a small amount of armor at the start of the game, because of Mid Dazzle, it can very much break through it and prevent Lone Druid from gaining an advantage at the very beginning of the game, giving his team the opportunity to overtake Lone Druid on items for killing him, by type: 
Spirit Vessel

Dazzle
* Poison Touch severely slows down Chen, deals damage over time and weakens his armor every time he gets attacked by Dazzle or any of his allies. Aghanim's Shard upgraded Poison Touch can hex Chen and prevent him from saving his allies with 
Hand of God.
* Neither Chen nor his converted creeps have burst damage at all, so Dazzle will always have plenty of time to save his allies with Shallow Grave.
* Dazzle can use Shadow Wave can heal his allies, kill Chen's creeps and damage Chen himself.
* Bad Juju can weaken Chen's armor, and the armor of his creeps every time Dazzle casts a spell while strengthening armor of Dazzle's allies.
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.
Dazzle
* 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, muting him and rendering him unable to do anything at all.
* 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. And since Terrorblade has no "real" burst damage potential outside from Sunder, Dazzle will usually have plenty of time to save an allied hero on which Sunder was used.
* Shadow Wave will always damage Terrorblade and his illusions whenever Terrorblade has no 
Metamorphosis available to use, while healing Dazzle's allies. Aghanim's Scepter upgraded Shadow Wave can also be used directly on Terrorblade, and bounce on both Terrorblade and his illusions alike, causing them to take damage and to be attacked by Dazzle. Shadow Wave can also pierce throught debuff immunity by Black King Bar, one of the items Terrorblade relies on to survive in teamfights.
* Bad Juju can weaken Terrorblade's armor every time Dazzle casts a spell while strengthening armor of Dazzle's allies.
Additional:

Shadow Wave can also pierce throught debuff immunity by Black King Bar, one of the items Terrorblade relies on to survive in teamfights.
* Bad Juju can weaken Terrorblade's armor every time Dazzle casts a spell while strengthening armor of Dazzle's allies.
Dazzle
* Venomancer's damage-over-time abilities are easier to heal through with numerous Shadow Waves than other types of damage, and it's simple to time a Shallow Grave until the last possible second to save a teammate from them.
Dazzle
* 
Mirror Image's illusions can easily walk straight at Dazzle and attack him, due to Dazzle's lack of reliable AoE nukes or disables.
* 
Ensnare roots Dazzle or his allies, making it harder to stay in range of Dazzle's saving abilities.
* 
Song of the Siren can be used to initiate a fight with superior positioning, potentially zoning Dazzle's high-impact spells out of the fight.
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.
Dazzle
* Dazzle can instantly destroy all of Naga Siren's illusions from Mirror Image with Aghanim's Shard upgraded Poison Touch used on her or any of her illusions.
Morphling
* Morphling's high mobility allows him to easily get close to Sniper, who likes to keep his distance from enemies.
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.
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.
Dazzle
* Poison Touch allows Dazzle to harass both, Io and it's tethered target on lane. Aghanim's Shard upgraded Poison Touch can also hex both, Io and it's tethered target, preventing them from escaping with Relocate, and also disarming them, silencing them, muting them and rendering them helpless against Dazzle and his allies.
* Io's damage output is one of the weakest, therefore Dazzle will have plenty of time to save an ally with Shallow Grave from gank by Io and it's tethered target.
* Shadow Wave will always hit both, Io and it's tethered target if they are near the ally Dazzle uses Shadow Wave on, while healing Dazzle's allies near them. Aghanim's Scepter upgraded Shadow Wave can bounce on both, Io and it's tethered target, causing them both to take damage and to be attacked by Dazzle. And unlike Io who doesn't get healed while using Tether, Shadow Wave will always heal Dazzle no matter on which of his allies he uses it on.
* Bad Juju will cause both, Io and it's tethered target to lose armor every time Dazzle casts a spell while strengthening armor of Dazzle's allies.
Additional:
* Poison Touch allows Dazzle to harass both, Io and it's 
Tethered target on lane. Aghanim's Shard upgraded Poison Touch can also hex both, Io and it's Tethered target, preventing them from escaping with Relocate, and also disarming them, silencing them, muting them and rendering them helpless against Dazzle and his allies.
* Io's damage output is one of the weakest, therefore Dazzle will have plenty of time to save an ally with Shallow Grave from gank by Io and it's Tethered target.
* Shadow Wave will always hit both, Io and it's Tethered target if they are near the ally Dazzle uses Shadow Wave on, while healing Dazzle's allies near them. Aghanim's Scepter upgraded Shadow Wave allows Dazzle Shadow Wave directly on Io and it's Tethered target which can also bounce on both, Io and it's tethered target, causing them both to take damage and to be attacked by Dazzle. And unlike Io who doesn't get healed while using Tether, Shadow Wave will always heal Dazzle no matter on which of his allies he uses it on.
* Bad Juju will cause both, Io and it's tethered target to lose armor every time Dazzle casts a spell while strengthening armor of Dazzle's allies.
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.
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.
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.
Dazzle
* Shallow Grave prevents Legion Commander from killing her opponents in Duels.
* Shadow Wave will heal an ally caught in a Duel, as well as dealing damage to Legion Commander.
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.
Dazzle
* Shadow Wave provides good sustain against Tinker's spammable abilities.
* Shallow Grave can stop Tinker from bursting down a target.
Morphling
* Heroes with Linken's Sphere as core item: Weaver, Morphling, Medusa.
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
Dazzle
* Heroes that can save their allies can be a big problem for Mars: Dazzle, 
Omniknight.
Morphling
* Heroes with high mobility will be able to avoid Gyrocopter's area attacks: Storm Spirit, Morphling, Ember Spirit
Dazzle
* 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.
Dazzle
* Heroes with abilities that reduce armor will make Huskar very vulnerable: Weaver, Dazzle, 
Bristleback, 
Vengeful Spirit.
Dazzle
* 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.
Dazzle
* 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.
Dazzle
* Dazzle's lack of a true disable makes him a relatively vulnerable target for Phantom Assassin.
* Coup de Grace will often kill Dazzle's teammates before he has a chance to use Shallow Grave.
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.
Dazzle
* 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
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,

Morphling
* Heroes who commonly buy Linken's Sphere: 
Luna, Weaver, Morphling, Queen of Pain, Ember Spirit.
Dazzle
* Hex abilities can cancel the channelling of Fiend's Grip : Lion, Shadow Shaman, Dazzle from Aghanim's Shard with upgraded Poison Touch.
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.
Dazzle
* Heroes with armor reducing abilities greatly hinder Visage's defense like 
Slardar and Dazzle.
Morphling
* 
Necrophos's 
Reaper's Scythe can finish off a low-health Morphling.
Dazzle
* Reaper's Scythe is very predictable and gives Dazzle plenty of time to react with Shallow Grave: Dazzle just has to keep a close eye on his allies below 50% health.
* However, Dazzle must be sure to use Shadow Wave on that ally immediately after, or they will die from 
Heartstopper Aura when the Shallow Grave ends!
Additional:
* Dazzle's Shadow Wave is a spammable healing ability that spreads around his entire team, slowing the death of his teammates as effectively as Necrophos spreads damage to them.
* If not immediately, Shallow Grave delays his ally from gradually dying to Necrophos's abilities, especially Reaper's Scythe.
* However, bear in mind that Dazzle's Poison Touch, Shadow Wave and Bad Juju all deal physical damage, and Dazzle has no abilities to help him deal magical damage at all, which can cause problems for Dazzle to kill Necrophos if he uses Ghost Shroud to protect himself.
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.
Dazzle
* Shallow Grave can prevent the death of an ally that is trapped inside the Chronosphere.
* Shadow Wave lets Dazzle heal allies and damage enemies from outside Chronosphere.
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.
Dazzle
* Heroes that can deny Slark early kills will prevent him from snowballing: Dazzle, 
Abaddon.
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.
Morphling
* Jumping on Axe with
Waveform will make Morphling an easy target for a counter-initiation with Berserker's Call.
Attribute Shift (Agility Gain), and also because his abilities cost health to use. This makes him especially vulnerable to Culling Blade.
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 is often played at low health to maximize the bonuses from
* However, Morphling is a common
*
Dazzle
* Culling Blade ignores the protection from
Shallow Grave and will kill any target whose health is low enough. This makes Axe one of the hardest counters to Dazzle, and he neutralizes one of Dazzle's most important abilities.
Culling Blade kills any target under the health threshold, even through Shallow Grave.
