* 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.

* Earth Spirit does not fly a small distance on Rolling Boulder using Stone Remnant, which will be a big problem for Life Drain, since Pugna will stop receiving health from breaking the distance of the ability, which will give the Earth Spirit team a chance to kill Pugna, by the way, this also works well with Boulder Smash, which pushes the enemy and can annoy the distance
* Earth Spirit has excellent control with a small recharge on Rolling Boulder and Geomagnetic Grip, which can knock down Pugna`s Life Drain, as well as completely turn him off in a fight, because he is very dependent on his abilities
* Magic damage from Earth Spirit's abilities can be disastrous for Decrepify, as it will kill him very quickly, and if Earth Spirit collects Ethereal Blade in such a game, it can easily destroy Pugna in one Rolling Boulder hit
* Earth Spirit also turns out to be a strong decision against Nether Ward, because he experiences it with his large amount of health, and if he collects Heart of Tarrasque(and Bracerin early game)in such a game, he may not feel it at all and calmly control Pugna with his abilities

* 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.

* Pugna only deals magical damage, which Anti-Mage is exceptionally resistant due to Counterspell.
* Anti-Mage can dispel Decrepify with Manta Style.
* Pugna has a very large mana pool. This allows Anti-Mage to constantly deal bonus damage to Pugna with Mana Break and devastate Pugna's entire team with Mana Void.
Additional:
* Since Pugna relies on his teammates for protection, it is fairly common for Anti-Mage to get multiple kills with a single use of his Mana Void on Pugna if he's missing a considerable portion of his mana.
* Pugna's massive mana pool will result in Anti-Mage's Mana Break almost always dealing the bonus damage from the mana burn.
* Counterspell negates a large amount of Pugna's damage, as most of Pugna's damage comes from his spells.
* Blink can be used to get out of a bad situation, and Pugna has no way to prevent him from casting it.

* 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.

* Phantom Lancer creates way too many illusions for Pugna's Life Drain to destroy, overwhelming him easily.
* Doppelganger can dodge Nether Blast or dispel Decrepify.
* Diffusal Blade is a common item for Phantom Lancer to burn Pugna's large mana pool and deals a large amount of damage in the process.
Additional:
* Though Life Drain instantly destroys illusions, Phantom Lancer creates way too many for Pugna to handle.
* A good Phantom Lancer will also dodge your Nether Blast with Doppelganger.
* Phantom Lancer is the most natural Diffusal Blade carrier to burn Pugna's very large pool of mana away and deal a large amount of damage in the process.

* Earthbind disables Waveform, effectively keeping Morphling in place for an extended period of time, allowing Meepo to deal considerable damage with Poof.

* Pugna's Nether Ward doesn't really hurt Meepo since he usually buys attribute items to tank up and can be killed very quickly by 4 clones. Decrepify can amplify Poof's damage should Pugna use it to avoid Meepo's right clicking.

* 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.

* Both Jakiro's Ice Path and Liquid Frost can be used to cancel Life Drain from either Jakiro or an ally.
* Decrepify only makes Pugna even more vulnerable to Jakiro's magical damage, And it has no adverse effects on Jakiro himself.
* Aghanim's Scepter upgraded Macropyre can deal pure damage-over-time and pierce debuff immunity, which can discourage Pugna from even trying to use Life Drain.
* Bear in mind, however, that Nether Ward can do some considerable damage to Jakiro due to high mana costs on his abilities.

* 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.

* Pugna is very reliant on his abilities for damage which Silencer can take advantage off. But he has to be careful around the Nether Ward as Silencer's abilities cost a lot of mana to use.

* 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.

* Puck can dodge Nether Blast and Life Drain with his Phase Shift, easily avoiding Pugna's strong burst magic damage.
* Waning Rift's silence allows Puck and its teammates to easily deal with Pugna, which cannot do the same to it, because with Puck it will be easy to avoid such an attack from the Decrepify.
* The Puck's combo: Waning Rift + Illusory Orb + Dream Coil doesn't have a huge amount of damage to feel the damage of the Pugna from Nether Ward, however, it may be quite enough to kill the Pugna solo at an early stage of the game with Witch Blade
Additional:
* Puck easily dodges the Nether Blast and the Pugna Life Drain with his Phase Shift, which is why he can easily avoid his strong magic damage
* The Puck's silence from the Waning Rift ability allows her team to easily cope with the Pugna, which cannot be said about the Pugna, because with the Puck it will be easy to avoid such an attack from the Decrepify
* The Puck's combo: Waning Rift + Illusory Orb + Dream Coil doesn't have a huge amount of damage to feel the damage of the Pugna from Nether Ward, however, it may be quite enough to kill the Pugna solo at an early stage of the game with Witch Blade

* All of Pugna's damage is magical, which can get blocked by Fate's Edict's 100% magic resistance.
* Oracle has two abilities that apply a dispel, which can easily remove Decrepify on his ally or Oracle.

* If Ursa uses Enrage, Pugna's Life Drain is next to worthless against him, due to Ursa taking 80% less damage, therefor Pugna heals by only 20% of the damage that the spell normally deals.
* It also dispels Decrepify, Even if you wait until he casted it, he can still dispel it with Shard upgraded Earthshock
* Ursa also commonly builds Skull Basher. With his high Attack Speed from Overpower. he can easily cancel Life Drain
* If Decrepify is defensivly casted, Ursa can still cast Earthshock both to slow you, and to deal amplified magic damage. He also commonly builds a Nullifier
* If Ursa jumps on you with a Blink Dagger he can easily wipe you out with Overpower.
* Ursa's Overpower can destroy a full health Nether Ward and still have a few swipes leftover, Also Ursa's low mana spells means he takes negligible damage from the Nether ward anyway.
* Ursa is also a common Diffusal Blade carrier, using it to both amplify his damage, but as his primary way to catch fleeing heroes
* Pugna is also the primary target of Ursa, due to him being both quite squishy, and a serious threat to his team, Ursa prioritizes the weakest link as Fury Swipes stacking damage will quickly demolish them, allowing Ursa to safely switch heroes

* 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.

* 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.

* 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.

* Spirit Siphon does a lot of magical damage, especially in the early game. This allows her to demolish low health heroes such as Zeus, Pugna, especially when combined with her other spells.

* 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.

* Nether Blast's animation makes it easy to time Spiked Carapace for a stun.
* Pugna has the largest intelligence gain in the game, making him a prime target for Mana Burn.
* Pugna needs to channel Life Drain, making him easy to hit with Impale.
Additional:
* Due to Pugna's incredible intelligence growth and terrible strength growth, Nyx should always be able to take you out with his combo, with or without an added Dagon. Mind Flare will deal a large amount of damage in particular, especially in the late game.
* Spiked Carapace is also a great tool versus Pugna. A good player will wait for you in Vendetta until you farm a creep wave with Nether Blast and reflect it back at you as their initiation and setup for Impale.

* Primal Beast has multiple ways to cancel Life Drain very quickly.
* Pugna has a very low strength gain and as a support does not have much gold to buy health items, making him vulnerable to Primal Beast's onslaught of magical damage.
* Ironically, Decrepify actually just increases Primal Beast's damage on the targeted ally if Trample is activated. However, it can be used to slow him down and prevent any further Trample damage.

* Luna can deal constant damage to Pugna through the low-cooldown Lucent Beam and her right clicks.
* Life Drain will be always canceled by Lucent Beam if Pugna does not have Black King Bar.
* Decrepify can be suicide against Luna due to Lucent Beam and Eclipse.
* Nether Ward is rather weak against Luna because unlike other heroes who rely on magical damage to damage or kill enemies, yet their ablities have very high mana costs, Luna does not have abilities that cost a lot of mana and Luna mostly uses her abilities to initiate a teamfight or to finish off fleeing enemy heroes.
* Luna is a common Black King Bar carrier, which allows her to protect herself against Pugna's only-magical damage output.
Additional:
* Luna can deal constant damage to Pugna through the low-cooldown Lucent Beam and her right clicks.
* Life Drain will be always canceled by Lucent Beam if Pugna does not have Black King Bar.
* Decrepify can be suicide against Luna due to Lucent Beam and Eclipse.
* Nether Ward is rather weak against Luna because unlike other heroes who rely on magical damage to damage or kill enemies, yet have very high mana costs, she does not have abilities that cost a lot of mana and Luna mostly uses her abilities to initiate a teamfight or to finish off fleeing enemy heroes.
* Luna is a common Black King Bar carrier, which allows her to protect herself against Pugna's only-magical damage output.

* 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.

* Life Drain does not instantly kill the illusions from Phantasm
* Chaos Bolt and Reality Rift can easily interrupt the channeling from Life Drain.
* Reality Rift makes it harder for Pugna to keep his distance between Chaos Knight.
* Nether Ward barely deals any significant damage on Chaos Knight as Chaos Knight's abilities do not cost a lot of mana
* The overwhelming damage of Chaos Knight and his illusions will do a quick work on Pugna's poor HP pool, or safely remove the Nether Ward from the battlefield.

* 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.

* 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.

* Pugna's low health and reliance on channeled abilities make him very vulnerable to Tusk, although Pugna can win in a straight up 1v1 later in the game.

* 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.

* Fragile heroes: Bounty Hunter has decent nuking capabilities with Shiruken Toss and Jinada thus making fragile heroes easy picks for ganking. Few examples of such heroes are:Crystal Maiden, Pugna, Skywrath Mage, Io, Witch Doctor, etc.

* Heroes with channeled abilities can be interrupted by a long-range Fissure: Crystal Maiden, Witch Doctor, Bane, Pugna, Pudge.

* Heroes who build a Black King Bar (or have any sources of spell immunity) to channel abilities/items can still get interrupted by Dismember: Enigma, Juggernaut, Phantom Assassin, Pugna, Elder Titan.

* Heroes who rely on channeling abilities can be interrupted in teamfights by Rolling Thunder: Crystal Maiden, Pugna, Witch Doctor

* 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.

* 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).

* Pugna is a very fragile hero who can easily get caught and killed by Storm Spirit's long range initiation.
* This is especially true if he has Orchid Malevolence or Scythe of Vyse.
* Pugna has no disables that can prevent Storm Spirit from escaping.
* Even though Ball Lightning requires high amount of mana, Nether Ward is ineffective since Storm Spirit is invulnerable while using it.
* Storm Spirit's other abilities cost very insignificant amount of mana for Nether Ward to be effective.

* 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.

* 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.

* 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.

* 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.

* Necrophos's Reaper's Scythe can finish off a low-health 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.

* 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.

* Winter Wyvern's Winter's Curse turns Morphling's high attack damage and attack speed against his targeted teammate.

* Sniper's huge range makes him an unviable target to use Life Drain on, forcing Pugna to risk playing out of position to use it on Sniper.
* Sniper's Shrapnel can be used to provide vision on Nether Ward, and his range allows him to easily take it out.
* A clumsy Pugna may accidentally boost Sniper's Shrapnel and Assassinate damages if he recklessly uses Decrepify on himself or his allies.

* 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.

* 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.

* 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.

* Pugna's squishiness and lack of mobility make him easy prey for a Hookshot initiation.
* Clockwerk's high health, low mana costs, and lack of reliance on Blink Dagger make Nether Ward ineffective.
* Battery Assault shuts down Aghanim's Scepter upgraded Life Drain, as the repeated ministuns prevent Pugna from channeling for an extended length of time.
Additional:
* Clockwerk loves to Hookshot low health, immobile targets like Pugna.
* Pugna's Life Drain gets immediately and repeatedly (if an Aghanim's Scepter was purchased) cancelled due to Battery Assault, especially if Pugna is trapped inside Power Cogs.
* Clockwerk also loves to build Blade Mail, which will deal more damage to Pugna than Clockwerk due to Pugna's low health pool.
* Finally, both Hookshot and Rocket Flare can allow him to finish off Pugna out of range of his Nether Ward.

* 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.

* Heroes with no mobility will take some good damage from Sand King's spells: Dragon Knight, Jakiro, Pugna, Earthshaker.

* 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.

* Underlord's Atrophy Aura reduces Morphling's high base damage gained through agility shift.
