* Morphling's naturally high armor thanks to his high agility makes it hard for Phantom Assassin to take him down with Coup de Grace.
* Phantom Assassin is vulnerable to magical damage, falling easily to Adaptive Strike + Ethereal Blade combo.
Additional:
* Morphling's high armor serves as a direct counter to Phantom Assassin, causing her attacks to do far less damage. She is also very vulnerable to burst damage, and can be brought down quickly using his Ethereal Blade and Adaptive Strike combo.

* Puck relies mainly on magical burst damage, which Phantom Assassin is most vulnerable against.
* Phase Shift and Illusory Orb disjoint Stifling Dagger, also allowing to kite Phantom Assassin.
* Dream Coil will stun Phantom Assassin if she uses Phantom Strike to blink away.

* Morphling's high mobility allows him to easily get close to Sniper, who likes to keep his distance from enemies.
* Sniper's low health also makes him extremely vulnerable to Morphling's Ethereal Blade and Adaptive Strike combo.

* Sniper has no spells to disable Puck. He lacks a silence to prevent spell casting and a stun to disable, allowing Puck to act instantly against Sniper.
* Sniper's main strategy is to attack his enemies from safe distance. Illusory Orb, combined with Blink Dagger makes it easy for Puck to get to Sniper. Due to his low health, he is also easily nuked down by Puck.
* The status debuff placed by Assassinate on its target makes it very easy to avoid it. Puck has 2 (3 when having Blink Dagger, 4 when having Eul's Scepter of Divinity, 5 when having Linken's Sphere) methods to disjoint or dodge the projectile, making it a bad spell for finishing off Puck.

* Low health spellcasters: Lina, Witch Doctor, Tinker, Keeper of the Light, all rely heavily on their spells and are fragile heroes. They all also have avoidable spells, allowing Puck to get to them and quickly burst them down.

* 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.

* By using Morph, Morphling can use Windrun and Shackleshot to counter Windranger herself.
* Waveform can allow Morphling to easily chase down Windranger.
* Windranger's low health also makes her vulnerable Morphling's magical nukes, especially the Ethereal Blade and Adaptive Strike combo.

* Windranger heavily relies on her abilities for any form of tactical advantage and damage. A well timed silence will make her useless: Puck,Silencer, Death Prophet, Skywrath Mage, Drow Ranger, Earth Spirit, Grimstroke.

* 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 can easily kill Bloodseeker with Ethereal Blade and Adaptive Strike combo if either hero is under the effects of Bloodrage.
Additional:
* 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.
* Morphling usually builds Ethereal Blade, which can be used to turn himself or an ally ethereal, and avoid Bloodseeker's attacks.

* Any Hero with high mobility will be neutralized by dream coil: Queen of Pain, Storm Spirit, Ember Spirit, Lycan, Bloodseeker, Anti-Mage, Timbersaw

* Morphling common combo Ethereal Blade and Adaptive Strike (Agility) can easily burst down Terroblade, bypassing his high armor.
* Morphling is likely to burst down Terrorblade due to his high armor, Attribute Shift.

* 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, so he is able to finish of Terrorblade before he has a chance to Sunder.

* Melee heroes that get kited easily have hard times dealing with Puck without any lockdowns, as Puck is one of the most mobile heroes. Heroes like Sven, Lifestealer, Ursa and Alchemist may have problems to get to Puck without proper initiation items. They also lack reliable lockdowns, as their disables are easily avoidable for Puck, or are just a soft disable.

* Lifestealer is a great target for Morphling to use Morph, as he can use Rage to gain spell immunity and a movement speed boost.

* All of Puck's abilities are active making Demonic Purge break from Aghanim's Scepter useless.
* Shadow Demon will find a hard time catching a Puck, as he can get away with Illusory Orb or even Waning Rift;
* Puck can dodge Shadow Poison waves and potentially avoid the damage from Demonic Purge with Phase Shift. Furthermore, after Disruption ended, Puck can use Phase Shift to avoid any further danger and can blink away with Blink Dagger.
* Waning Rift can be used to initiate Shadow Demon, prevent him from using any spells.
* Puck usually builds Eul's Scepter of Divinity to dispel Shadow Poison and Soul Catcher and Linken's Sphere to block Disruption and Demonic Purge.

* Phase Shift allows Puck to dodge all of Earthshaker's abilites.
* Waning Rift disables Earthshaker's stuns, leaving him and his team vulnerable.
* Dream Coil takes a stun from Earthshaker if he tries to escape from Blink Dagger or Enchant Totem upgraded from Aghanim's Scepter.

* Illusory Orb and Waning Rift are effective nukes against Phantom Lancer's illusions, especially in the early game.
* Dream Coil limits Phantom Rush's mobility during teamfights.

* 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.

* 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.
* However, Morphling should be wary of using his Ethereal Blade combo on a Clockwerk with Blade Mail.

* Dream Coil and Wanning Rift prevent Pangolier from using Swashbuckle and Rolling Thunder, If Puck has aghanim's scepter, Dream coil will stop Rolling Thunder from moving entirely.
Additional:
* Illusory Orb and Waning Rift provides great mobility, allowing Puck to catch up Pangolier when he is attempting to disengage with his own skills.
* Dream Coil's leash act almost as a literal silence to Pangolier, disabling half of his arsenal and also piercing his spell immunity during Rolling Thunder. Also Dream Coil's very long duration will make Pangolier wasting his entire ultimate rolling in place.

* Although Phoenix has many ways to disable a Blink Dagger, the high cooldown of all of his spells makes them not as reliable for this. Also, his spells cost him a lot of health to use, making it easy for him to get nuked down.
* Waning Rift prevents Phoenix from using Supernova to refresh himself, giving Puck's team time to finish Phoenix off, or allow Puck to burst him down.
* Dream Coil prevents Phoenix from using Icarus Dive without consequences. Waning Rift and Dream Coil are also able to cancel his Sun Ray, which is his main source of damage in the late game.

* 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 abilities are area-targeted, and will hit Dark Willow when she uses Shadow Realm.
* Illusory Orb allows Puck to bypass Bramble Maze, close the gap and silence Dark Willow with Waning Rift.
* Phase Shift helps Puck dodge attacks charged by Shadow Realm, and is easily timed against Terrorize's long cast time..

* 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 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.

* By using Morph, Morphling can use Death Pact 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.

* 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.
