Pugna
* Heroes who rely on channeling abilities can be interrupted in teamfights by Rolling Thunder: 
Crystal Maiden, 
Pugna, 
Witch Doctor
Clinkz
* Heroes who rely on burst physical damage are affected by Lucky Shot's disarm: 
Terrorblade, 
Sven, 
Clinkz, 
Windranger, 
Alchemist, 
Dragon Knight, 
Legion Commander
Clinkz
* Clinkz will often roam the map alone, and Treant Protector's 
Nature's Guise allows him to set up kills with his allies on Clinkz from invisibility.
* Treant Protector's very high damage allowing him to trade hits or contest last hits with Clinkz, while 
Living Armor can be used to sustain the harass.
* Living Armor protects any of Treant's allies ganked by Clinkz.
* In teamfights, Treant Protector's 
Overgrowth can disarm Clinkz, preventing him from turning invisible and holding him in place even if he has a 
Black King Bar.
* 
Leech Seed slows Clinkz, preventing him from repositioning or fleeing away from danger.
Pugna
* 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.

* Luna is a common Black King Bar carrier, which allows her to protect herself against Pugna's only-magical damage output.
Clinkz
* 
Skeleton Walk is not enough to outrun Bloodseeker, and is detected by Thirst.
* Because of his low health and high damage output, Clinkz will get obliterated by 
Blade Mail
Additional:
* 
Thirst reveals Clinkz if he tries to escape with Skeleton Walk with low health. It also allows Bloodseeker to match or exceed Clinkz's speed.
* 
Rupture negates the mobility provided by Skeleton Walk in any attempt to escape or reposition in fights.
* Bloodseeker can easily build items to counter Clinkz, including 
Talisman of Evasion upgrades, Blade Mail, and armor items.
Pugna
* 
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.
Pugna
* 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
Pugna
* 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.
Pugna
* 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

Clinkz
* Clinkz has no stun and likes to keep his distance from targets, making Marksmanship very deadly.
* Clinkz also has low health, making him a perfect hero to initiate onto with Gust.
* Gust can also prevent Clinkz from using 
Burning Barrage.
Clinkz
* Possibly Clinkz's worst enemy. He has many tools to utterly destroy Clinkz.
* 
Charge of Darkness can be used on Clinkz if Spirit Breaker's team spots him anywhere. This charge will track his location through Skeleton Walk's invisibility and movement speed bonuses.
* When Spirit Breaker charges onto Clinkz, he can easily use 
Dust of Appearance to guarantee a reveal on him while stunned.
* All three of Spirit Breaker's spells help him and his team quickly close the gap to Clinkz even at the edge of his attack range or when running away with Skeleton Walk.
* Spirit Breaker's high strength and above average armor makes him able to endure Clinkz's onslaught, meanwhile Clinkz will be heavily threatened if Spirit Breaker procs a 
Greater Bash.
Additional:
* Once caught with dust, Clinkz could be locked down for a long time by Spirit Breaker and has nowhere to escape.
* Charge of Darkness provides shared vision over its target, showing Clinkz even when he is in Skeleton Walk.
Pugna
* 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
Clinkz
* Slardar can reveal Clinkz with 
Corrosive Haze and make him easy to kill, and his 
Bash of the Deep also hits hard against Clinkz's naturally low health pool.
* Slardar's 
Guardian Sprint can catch up with Clinkz's Skeleton Walk.
* The stun and slow from Slardar's 
Slithereen Crush can hold Clinkz in place.
Additional:
* Clinkz survivability depends entirely on Skeleton Walk. Corrosive Haze not only makes its invisibility useless, but also makes Clinkz even more vulnerable to physical damage.
Pugna
* 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.
Pugna
* 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.
Pugna
* 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.
Pugna
* 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.
Clinkz
* 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.
Clinkz
* 
Scorched Earth deals damage to Clinkz during Skeleton Walk.
* 
Doom shuts down Clinkz entirely, as it prevents him from casting any of his spells and contributing a large amount of damage in teamfights.
Pugna
* 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.
Pugna
* Heroes with no mobility will take some good damage from Sand King's spells: Dragon Knight, 
Jakiro, Pugna, 
Earthshaker.
Clinkz
* Sand King is a strong ganker, allowing him to shut down squishy heroes in the early game: 
Phantom Assassin, Clinkz, 
Sniper, 
Enchantress.
Pugna
* Pugna's Nether Ward damages Sand King when he channels Epicenter, preventing him from using Blink Dagger afterward.
Clinkz
* 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.
Clinkz
* In general, Brewmaster's Cinder Brew and Thunder Clap makes him good against physical damage carries: 
Ursa, Clinkz, Faceless Void, Troll Warlord, 
Templar Assassin, Phantom Assassin.
Pugna
* 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.
Pugna
* 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.
Clinkz
* 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.
Pugna
* 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.
Clinkz
* Heroes who build mana boosting items but have low mana regeneration are especially vulnerable against Mana Break and Mana Void: 
Timbersaw, Slark, Shadow Fiend, Clinkz, 
Bristleback 
Nyx Assassin, 
Magnus
Clinkz
* Anti-Mage's Counterspell provides no protection against Clinkz's physical damage output.
* Clinkz can easily rush an 
Orchid Malevolence to prevent Blinking, although Anti-Mage can easily dispel it via Manta Style.
* Clinkz does heavy damage to towers, and can take map control away from Anti-Mage to limit the space he has to farm early game. If Clinkz is ahead he is capable of ending the game before Anti-Mage becomes a threat. He can also match Anti-Mage's ability to split push.
Clinkz
* Heroes with high armor like Dragon Knight, or with abilities to cause attacks to miss like Phantom Assassin, Riki and 
Tinker will be hard to deal with, as Clinkz relies almost entirely on physical attacks.
Additional:
* The extra damage from 
Searing Arrows is largely blocked by Dragon Knight's armor.
* Clinkz has too low health to survive a gank.Getting stunned keeps him down long enough for a reaction.
* Breathe Fire reduces his damage, as he almost exclusively deals physical damage.
Pugna
* 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.
Clinkz
* Heroes who can take advantage of Oracle's low mobility or catch him out of position, such as Clinkz and Anti-Mage, can easily pick him off.
Clinkz
* The long silence at night prevents Clinkz from escaping with invisibility if Night Stalker can sneak up on him. He also has really low base health, so Night Stalker can usually kill him alone during one cast of Crippling Fear at night.
Pugna
* Heroes that can punish aggressive heroes, such as: 
Leshrac, 
Shadow Demon, Pugna, 
Death Prophet.
Pugna
* 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.
Pugna
* Heroes with mana burn: Nyx Assassin, 
Invoker, 
Outworld Destroyer, Pugna, 
Lion
Clinkz
* 
Hex and 
Earth Spike can hold Clinkz down, giving him no chance to use Black King Bar or Skeleton Walk.
* 
Finger of Death quickly kills Clinkz due to his low health.
Pugna
* Nether Ward will be problematic for heavy nukers and spammers like 
Skywrath Mage, 
Lina, Lion and Invoker, but Pugna must not use Decrepify defensively against them as he will be helping them out more than anything.
Pugna
* 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.
Clinkz
* Invisible heroes all have the element of surprise. Provided they deal enough damage, Sniper should be vanquished very quickly: Clinkz, Riki, 
Bounty Hunter.
Clinkz
* Lina's damage burst can quickly kill Clinkz before he saves them with Skeleton Walk.
* Fiery Soul attack speed bonus removes 
Burning Army easily in all stages of the game.
Pugna
* Nether Ward will be problematic for heavy nukers and spammers like Skywrath Mage, Lina, Lion and Invoker, but Pugna must not use Decrepify defensively against them as he will be helping them out more than anything.
Pugna
* Nether Blast can deal high damage to Chen and clear waves of his creeps.
* Decrepify can be used to waste the duration of 
Penitence.
* Nether Ward can discourage Chen from using Penitence, 
Holy Persuasion and 
Hand of God due to their fairly high mana costs.
* Life Drain can often kill Chen or any of his allies before he can save them with Hand of God thanks to it's high damage and low cooldown.
Clinkz
* Clinkz's Skeleton Walk allows him to easily sneak on Chen and bypass his creeps. It also allows him to escape from them.
* Clinkz can easily kill Chen's creeps with 
Death Pact and gain gold, health, damage and abilities from them when upgraded with Death Pact Steal creep abilities talent.
* Clinkz naturally loves buying 
Gleipnir, which allows him to easily root Chen and his creeps and to kill them more easily with Burning Barrage from 
Aghanim's Shard.
* Clinkz can kill Chen or any of his allies with his physical damage burst from 
Strafe, 
Tar Bomb and Burning Barrage from Aghanim's Shard before he can use Hand of God. Especially when Clinkz has Gleipnir and 
Daedalus. Clinkz can also buy 
Bloodthorn to prevent Chen from even trying to use Hand of God.
Pugna
* Pugna's Decrepify allows him to save allies from being ganked by Viper, since Viper mostly relies on direct attacks in order to deal damage.
* Nether Ward can discourage Viper from spamming his abilities.
* Viper's damage over time is not enough to kill Pugna as he will have more than enough time to save himself (or his allies) with Life Drain and Viper has no solutions to cancel it.
* Pugna has no passive abilities, which renders 
Nethertoxin nearly useless.
Clinkz
* Clinkz does not have any passive abilities at all, making Nethertoxin nearly useless.
* Viper's 
Corrosive Skin provides no protection against Clinkz's physical damage output.
Pugna
* Enigma's abilities have a huge mana cost, meaning that Nether Ward will deal a lot of damage to Enigma.
* Pugna can heal allies trapped inside Black Hole thanks to Life Drain, Pugna can also damage multiple of Enigma's allies around him with Life Drain when he casts it on Aghanim's Shard upgraded Nether Ward during teamfight.
* Nether Blast can easily kill Eidolons, especially when Enigma is pushing.
* Even though Pugna cannot cancel 
Black Hole on his own, smart Pugna can buy Orchid Malevolence to stop Enigma from channeling Black Hole and make him more vulnerable to counter-attacks with Decrepify and Life Drain.
Additional:
* Enigma's abilities have a huge mana cost, meaning that Nether Ward will deal a lot of damage to Enigma.
* Pugna can heal allies trapped inside Black Hole thanks to Life Drain.
* Nether Blast can easily kill Eidolons, especially when Enigma is pushing.
Clinkz
* Despite Clinkz's fragility, his harassment in the early game can be devastating; as he can kite Enigma and his Eidolons and claim their bounty with Burning Barrage and Tar Bomb.
* Clinkz often goes for a disabling item like Bloodthorn or Gleipnir, which allows him to cancel Enigma's Black Hole until Enigma gets Black King Bar. Gleipnir can also root Enigma, preventing him from using Blink Dagger to escape from Clinkz.
* Even with Black King Bar, Clinkz can still easily kill Enigma as all of his abilities ingore spell immunity, and Enigma is a very easy target for Burning Barrage, which means Clinkz can solo Enigma at any stage of the game unless Clinkz is caught in Black Hole.
Pugna
* Troll Warlord can't switch targets at will, in order to build 
Fervor stacks, which makes it easy to use Decrepify in order to save allies
* During 
Battle Trance, Pugna can easily use Nether Blast, Decrepify and Life Drain on him
Clinkz
* With Bloodthorn, Clinkz becomes a strong counter to heroes who rely on evasion and blind such as Windranger, Phantom Assassin, Troll Warlord and 
Keeper of the Light.
Pugna
* Pugna easily copes on the line with the Keeper of the Light push with his Nether Blast, and in addition to Nether Ward, the Keeper of the Light is not able to throw 
Illuminate on creeps for a long time, so Pugna earns more gold and a level on the line
Additional:
* Pugna easily copes on the line with the Keeper of the Light push with his Nether Blast, and in addition to Nether Ward, the Keeper of the Light is not able to throw Illuminate on creeps for a long time, so Pugna earns more gold and a level on the line
Clinkz
* With Bloodthorn, Clinkz becomes a strong counter to heroes who rely on evasion and blind such as Windranger, Phantom Assassin, Troll Warlord and Keeper of the Light.
Pugna
* Nether Ward can do a ton of damage to Disruptor because of his high mana costs.
* Life Drain can be used to heal an ally trapped by Static Storm-Kinetic Field combo (if Pugna is not a target).
Clinkz
* Heroes that can pick you off: Clinkz, Nyx Assassin, 
Puck, Riki.
Pugna
* Any hero that can outrange Plague Ward can neutralize them without putting themselves at risk of receiving Poison Sting: 
Arc Warden, 
Chen, Clinkz, Drow Ranger, Lina, Mirana, 
Nature's Prophet, Pugna and Sniper.
* Special mention to heroes that outrange Plague Ward after obtaining talents that increase attack range.
Clinkz
* Any hero that can outrange Plague Ward can neutralize them without putting themselves at risk of receiving Poison Sting: Arc Warden, Chen, Clinkz, Drow Ranger, Lina, Mirana, Nature's Prophet, Pugna and Sniper.
* Special mention to heroes that outrange Plague Ward after obtaining talents that increase attack range.
Pugna
* Pugna's Decrepify makes sure that either Alchemist is unable to hit anyone while also being slowed and susceptible to magical damage, or can protect an ally from physical attacks. Besides, Pugna can push early on, when Alchemist is not strong enough to repel it, so by the time Alchemist comes online, he might be forced to sit in base.
Clinkz
* Clinkz can use Burning Army in teamfights which will cause a problem for Alchemist.
Clinkz
* Clinkz's item build often counters Hoodwink, including Black King Bar, 
Monkey King Bar, 
Heaven's Halberd, and Scythe of Vyse.
* Skeleton Walk can quickly escape Hoodwink abilities.
Pugna
* Pugna can save allies with both healing or by making them ethereal but needs to be careful of Sven's Aghanim's Scepter purge.
Clinkz
* Nature's Prophet is often by himself. Clinkz can use invisibility to hunt him down and kill him, although a Quelling Blade may be needed to cut through his 
Sprout. Orchid Malevolence may also be needed if 3-4 seconds are not enough time to kill him, as he can teleport away.
* Clinkz can match Nature's Prophet's ability to split push.
Clinkz
* Considering Rubick's abysmal armor, Rubick is a squishy target for Clinkz to gank on his own.
* None of his spells are useful except for Skeleton Walk.
* Clinkz usually builds Orchid Malevolence, which disables Rubick's ability to retaliate.
* Vast numbers of 
Sentry Wards are needed to deal with Clinkz because of Skeleton Walk, making it harder for Rubick to buy more expensive and more useful support items like 
Glimmer Cape or 
Mekansm.
Clinkz
* Ember Spirit's 
Flame Guard provides no protection against Clinkz's physical damage output.
* Ember Spirit's low armor and health make him easy to kill quickly if a teammate can hold him down.
* If Clinkz has farmed an item that can disable, he can sneak up to and hunt down Ember Spirit while he farms or split pushes alone.
Pugna
* Nether Blast will still hit Slark even if he is hidden during Shadow Dance.
* Even though Pugna can rarely target Slark directly with Decrepify, he can still use it defensively on an ally to prevent Slark from getting stacks.
* Despite being somewhat easy to break with Pounce, Pugna can damage Slark and provide vision over him with Life Drain.
Pugna
* Nether Ward can punish Timbersaw, as Timbersaw is a spell-caster with low cooldowns. Furthermore, Timbersaw usually appears in the midst of battle, placing himself in range of Nether Ward's Mana Flares.
* Timbersaw has no stuns or silences to stop Life Drain. Since all of Pugna's Spells are magical, the damage can be devastating to Timbersaw.
* Decrepify can further increase all the magical damage done to Timbersaw, bypassing the enhanced physical resistance he can get from 
Reactive Armor.
Additional:
* Nether Ward can punish Timbersaw, as Timbersaw is a spell-caster with low cooldowns. Furthermore, Timbersaw usually appears in the midst of battle, placing himself in range of Nether Ward's Mana Flares.
* Timbersaw has no stuns or silences to stop Life Drain. Since all of Pugna's Spells are magical, the damage can be devastating to Timbersaw, especially when combined with Decrepify.
Pugna
* Nether Ward punishes Leshrac's constant mana usage from spamming spells.
* Leshrac needs to be in the thick of the fight to deal damage, and so cannot escape from Nether Blast nor Life Drain easily.
Additional:
* Leshrac needs to be close to target in order to do damage, Pugna can outrun Leshrac with ease due to his superior movement speed.
* 
Split Earth can also be hard to land on Pugna for the same reason.
* Leshrac uses huge amounts of mana to do damage, Nether Ward forces him to either not contribute in a fight or kill himself in the process.
Pugna
* Nether Ward on its own can greatly hinder Invoker from casting many of his abilities, at least until he gets a significant amount of HP or is under the protection of spell immunity from Black King Bar
* Life Drain provides True sight, revealing Invoker through Ghost Walk, and forcing him or his allies to use an ability or item to interrupt its channeling
* Outside of Nether Ward's range, Invoker shall have the advantage, as Invoker has Tornado to purge Pugna's Decrepify when it is used defensively, Tornado or Cold Snap to prevent Pugna from channeling Life Drain
* A poorly used Decrepify on Pugna's allies means Invoker's abilities can be used to deal more damage to them.
Additional:
* Because Invoker relies on casting a large amount of spells to contribute to fights, Nether Ward can force him to not cast anything at all or take a large amount of damage to cast spells.
Pugna
* Nether Ward causes Death Pulse to actually damage Necrophos rather than heal him. Meanwhile, Reaper Scythe's gigantic mana cost while Necrophos is near the Nether Ward can often instantly kill him.
* Nether Blast and Life Drain both make quick work of Necrophos's small healthpool, especially during Ghost Shroud. The latter also makes him an unappealing target for Reaper's Scythe, and can often force Necrophos to use it defensively as he has no other means of interrupting his channeling.
Pugna
* Decrepify prevents Shadow Fiend from attacking for its duration, potentially preventing him from getting a kill.
* Nether Ward can do heavy damage to Shadow Fiend if he tries to cast his 
Requiem of Souls and his 
Shadowraze.
Additional:
* Decrepify prevents Shadow Fiend from attacking for its duration, potentially preventing him from getting a kill.
* Nether Ward can do heavy damage to Shadow Fiend if he tries to cast his Requiem of Souls or spam Shadowraze.
Clinkz
* Huskar's 
Berserker's Blood provides no protection against Clinkz's physical damage output.
* Huskar has no way to disrupt Clinkz's attacks and no way to kill Clinkz alone, as Clinkz can easily go invisible, teleport away, or even fight back.
* Clinkz will often build the items that counter Huskar and the items he usually builds. These include Black King Bar or Monkey King Bar for Heaven's Halberd, or a disable item like Scythe of Vyse or Bloodthorn to prevent him from using 
Inner Fire to disarm.
Clinkz
* Strafe, Tar Bomb and Burning Barrage from Aghanim's Shard allow Clinkz to quickly kill Io due to its low armor.
* Clinkz iz a hero that very often goes for Orchid Malevolence, and its upgrade Bloodthorn. Alternatively, Clinkz also loves to buy Gleipnir. And if Clinkz has both of them, he will be able to root and silence Io and prevent him from escaping with either 
Tether or 
Relocate.
Pugna
* Decrepify can be used on allies to prevent them from attacking Axe and triggering Counter Helix during Berserker's Call. He can also cast it on Axe to prevent anyone from attacking him.
* Life Drain can be used to heal himself or allies caught in Berserker's Call, preventing them from dropping low enough for Axe to kill them with Culling Blade.
Pugna
* All of Pugna's abilities are active, making Demonic Purge break from Aghanim's Scepter useless.
* Nether Ward punishes Shadow Demon's constant mana usage from spamming spells, especially Shadow Poison.
* An attempt to save an ally using Disruption can easily become a perfect setup for a Nether Blast for the enemy.
* Life Drain can be used to heal Pugna or an ally to save them from Shadow Demon's abilities.
* However, it can be cancelled by Disruption unless Pugna buys defensive items.
Pugna
* Decrepify prevents 
Omnislash damage, until Juggernaut gets a Nullifier.
* Without a disable, Pugna's high movement speed makes it harder to chase him with 
Blade Fury.
* Juggernaut has low mana and his skills cost large amount of mana. Nether Ward will hurt him more and even worse, the damage from the ward is inflicted before the Spell immunity provided by Blade Fury.
Additional:
* Decrepify is the perfect tool against Omnislash until he gets a Nullifier, and even then he will probably waste a couple of slashes before he uses it.
* Without an extra disable, Pugna's high movement speed makes it impossible to chase him with Blade Fury.
* Unlike some other carries like Slark or Phantom Assassin, Juggernaut's spells cost a hefty amount of mana and he will seriously get hurt by Nether Ward. Don't forget the damage from the ward is inflicted before the spell immunity is provided by Blade Fury.
Pugna
* Arc Warden can't use Magnetic Field to stall the damage of Nether Blast on towers, but he can buy Aghanim's Shard to diminish its damage.
* Arc Warden has no innate disables to stop Life Drain and Decrepify
* The short cooldown of both Life Drain and Decrepify also means Pugna can deal with Arc Warden and Arc Warden's clone simultaneously most of the time
* A good Pugna looks to end the match early while Arc Warden, a very item reliant hero, thrives in longer matches.
Clinkz
* Clinkz's high damage output and insane attack speed late-game can take Kunkka out of the fight before it begins.
* Burning Barrage and Searing Arrows together can kill allies easily even under Ghostship's buff.
* Skeleton Walk can allow Clinkz to make a quick escape after Kunkka's combo, or even avoid it all together.
Clinkz
* Clinkz relies heavily on the physical damage provided by Burning Barrage and Searing Arrows, which completely overrides the capabilities of Rage.
* Lifestealer's lack of disables will struggle to pin Clinkz down while in Skeleton Walk, and can allow Clinkz to kite him.
Pugna
* 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.
Pugna
* Heroes with high movement speeds like Pugna and Meepo can run around, to, or away from Snapfire during 
Mortimer Kisses and dodge the projectiles easily due to their slow speed.
* Heroes with mobility spells (such as 
Queen of Pain's 
Blink and 
Clockwerk with 
Hookshot) can easily avoid 
Lil' Shredder and Mortimer Kisses.
* Heroes with high movement speeds like Pugna and Meepo can run around, to, or away from Snapfire during Mortimer Kisses and dodge the projectiles easily due to their slow speed.
Clinkz
* Due to Tiny's non-existent agility gain, high physical damage heroes are more effective against him (Clinkz, Templar Assassin, Ursa, 
Wraith King etc).
Clinkz
* Heroes with high armor like Dragon Knight, or with abilities to cause attacks to miss like Phantom Assassin, Riki and Tinker will be hard to deal with, as Clinkz relies almost entirely on physical attacks.
Pugna
* Heroes that can apply early pressure before Phantom Assassin has farm are massive threats: 
Axe, 
Viper, Meepo, Jakiro, Pugna, Slark, 
Venomancer etc.
Clinkz
* With Bloodthorn, Clinkz becomes a strong counter to heroes who rely on evasion and blind such as Windranger, Phantom Assassin, Troll Warlord and Keeper of the Light.
Pugna
* Any hero who can counter-initiate in anticipation without getting caught in Reverse Polarity: Sven, 
Omniknight, 
Enigma, 
Luna, 
Naga Siren, 
Mars, Jakiro, Venomancer, 
Elder Titan, Faceless Void, 
Rubick, Keeper of the Light, Pugna, Invoker, 
Spectre, Alchemist, 
Treant Protector, Lina, 
Oracle, Zeus, 
Shadow Shaman, 
Phoenix, 
Razor, Huskar, 
Batrider, 
Kunkka, Tidehunter, Wraith King, 
Sand King, 
Medusa, 
Dawnbreaker.
Pugna
* Pugna: Decrepify prevent the Spirit bear from attacking or protect allies from it.
Clinkz
* Spectre can instantly escape Burning Army or hunt Clinkz with 
Haunt.
* Spectre can catch up to him with 
Spectral Dagger, even if he uses Skeleton Walk.
* 
Desolate allows Spectre to hit Clinkz through Skeleton Walk.
* 
Dispersion makes Spectre tanky and also reflects some damage back to Clinkz.
Additional:
* Spectre can catch Clinkz with Spectral Dagger, even if he uses Skeleton Walk.
* Spectre can instantly reach a ratting Clinkz with Haunt.
* Desolate's damage will melt him quickly, as he's alone most of the time.
Pugna
* Nether Blast is one of the best tower pushing abilities in the game, with a low cooldown. A competent Pugna will (at the very least) destroy tier 2 towers and make space for his team before Spectre can finally come online.
* Spectre's spells, while not spammable, have a fairly high mana cost, so Nether Ward can be fairly damaging to Spectre early game. The mana degen will also dampen Spectre's early game power significantly.
* Once Pugna gets Aghanim's Scepter, he can spam Life Drain on any illusion Spectre summons, whether it'd be from Haunt, Manta Style, or some other means.
* In addition, Pugna can disable Spectre's Desolate ability (although its damage is pure, it requires physical attacks) with his Decrepify ability, leaving Spectre only with Spectral Dagger.
Clinkz
* Heroes with good escapes can usually outmaneuver and escape from Spectre: Slark, Clinkz, Weaver
Clinkz
* With Bloodthorn, Clinkz becomes a strong counter to heroes who rely on evasion and blind such as Windranger, Phantom Assassin, Troll Warlord and Keeper of the Light.
Clinkz
* Any hero with high attack speed will be a threat to Phoenix when it initiates, as they can easily tear down a 
Supernova, perhaps even while debuffed by Fire Spirits: Juggernaut, Clinkz, Troll Warlord, 
Beastmaster, Lina.
Pugna
* Pugna's Decrepify prevents the target from taking physical damage or doing damage, which poses a huge problem for Lycan, as he mainly deals physical damage.
Pugna
* Any heroes with high intelligence, such as Invoker and Pugna.
Clinkz
* Ancient Apparition has no escape or reliable control and is very fragile, which makes him an easy target for anyone who can get on top of him, like Phantom Assassin or Clinkz.
Pugna
* Heroes who are reliant on physical damage will be nullified by Decrepify: Riki, Wraith King, Juggernaut.
Pugna
* Heroes with magical or pure damage output will not have any problems against Atrophy Aura at all: Luna, Lina, Jakiro, Pugna, 
Bane, 
Snapfire, 
Muerta, Nyx Assassin, Enigma, Tinker, Witch Doctor, Zeus, Crystal Maiden.
Clinkz
* Heroes who can harass Omniknight out of lane will keep him weak in the mid game: Viper, Venomancer, Clinkz.
Clinkz
* Heroes who rely on invisibility, such as Bounty Hunter, Clinkz, Mirana, Nyx Assassin and Riki, as they will be revealed if caught by Chronosphere.
Pugna
* Decrepify prevents Faceless Void from attacking trapped allies inside 
Chronosphere, wasting a large portion of its duration if Faceless Void can't dispel it.
Clinkz
* Fragile carries with no reliable escaping mechanism can be bursted down in no time: Sniper, Drow Ranger, Clinkz
Pugna
* Pugna's Decrepify can render Templar Assassin's physical attacks useless.
* Pugna can also cast Life Drain on Templar Assassin, burning her Refraction instances.
* On the other hand, Pugna generally has low health and armor. Use this to your advantage.
Clinkz
* Heroes who cannot fight back during Arena of Blood in the early and mid game: 
Abaddon, Anti-Mage, 
Broodmother, Luna, Sniper, Troll Warlord, Weaver, Clinkz.
Pugna
* Nether Blast, Decrepify and Life Drain deal high magical damage and bypasses Bulwark.
* Nether Ward reduces the amount of abilities Mars can use during fights and forces Mars to be careful about the heavy mana cost of Arena Of Blood.
* Pugna is one of few heroes that can contest Mars' ability to push and defend towers early on.
Clinkz
* 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.
Pugna
* 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:
* 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
Clinkz
* Even though 
Linken's Sphere will block your silence, you can cast Arcane Bolt to break it or wait until someone on your team breaks it. In addition, Linken's Sphere builders are usually squishy targets vulnerable to silences: Weaver, Queen of Pain, Morphling, Clinkz, etc. Don't forget that Ancient Seal also increases the magical damage these enemies take, along with silencing them.
Pugna
* Due to the high mana cost of his spells and the low cool down of them, Nether Ward can seriously damage Skywrath Mage if he isn't careful.
* Skywrath Mage's fragility makes him very susceptible to Pugna's high burst damage.
Additional:
* Nether Ward will make Skywrath Mage next to useless in fights, as his low hp pool will not allow him to sustain through the damage of the ward should he choose to cast spells. Be wary though that Skywrath's huge burst will make very quick work of Pugna's low hp should the ward be destroyed, and Decrepify won't help Pugna at all.
Clinkz
* Heroes with high armor like Dragon Knight, or with abilities to cause attacks to miss like Phantom Assassin, Riki and Tinker will be hard to deal with, as Clinkz relies almost entirely on physical attacks.
Pugna
* Nether Ward discourages Tinker from using abilities and items due to its high damage against heavy mana usage.
Clinkz
* 
Untouchable prevents Clinkz from harassing Enchantress in lane by lowering his attack speed.
* 
Nature's Attendants helps Enchantress to sustain through Clinkz's harassment in lane.
Pugna
* Amazingly, Enchantress has even lower health than Pugna. Though she does pack quite a punch through 
Impetus, she can't use it if she is under Decrepify.
* Pugna's Magical DPS is way greater than the heal from Nature's Attendants, which will also harm her quite a bit if she's next to Nether Ward.
Clinkz
* Heroes who rely on physical damage output to be effective will fare badly against Muerta's 
Pierce the Veil: Phantom Assassin, Terrorblade, Drow Ranger, Lifestealer, Anti-Mage, Alchemist, 
Lycan, Clinkz, Sniper.
Pugna
* Heroes that commonly attack ethereal units will not have any problems against Muerta's Pierce The Veil: Tinker, Jakiro, Lina, Luna, Pugna or 
Ogre Magi, Enigma, Batrider, Techies, Broodmother, Dawnbreaker, Shadow Shaman, Bane, Tinker, Venomancer, Arc Warden.
Clinkz
* Frostbite will reveal invisible heroes for its duration, making it a good tool against any such hero (Riki, Bounty Hunter, Weaver, or Clinkz for example), or as a soft counter to 
Shadow Blade, if it is used first. This can be an amazing tool to ensure that Dust of Appearance is used on the unit in question, and not wasted in not catching anything.
Clinkz
* Heroes who can easily harass Crystal Maiden out of lane in the early game (Clinkz, Viper) can prevent Crystal Maiden from being able to level effectively, and can ultimately slow down her level 6, 12, and 18 to a point where enemy carries already have items to address her ultimate.
Pugna
* 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.
Clinkz
* Heroes with a high degree of mobility and invisibility are hard to catch with Meat Hook: 
Ember Spirit, Riki, Clinkz, Queen of Pain.
Pugna
* Heroes with channeled abilities can be interrupted by a long-range Fissure: Crystal Maiden, Witch Doctor, Bane, Pugna, 
Pudge.
Clinkz
* Heroes with invisibility and high mobility can jump on and focus down Earthshaker before he has a chance to initiate: Clinkz, Slark, 
Storm Spirit
Clinkz
* Heroes with high armor like Dragon Knight, or with abilities to cause attacks to miss like Phantom Assassin, Riki and Tinker will be hard to deal with, as Clinkz relies almost entirely on physical attacks.
Additional:
* Smoke Cloud prevents the use of Death Pact, Searing Arrows and Skeleton Walk, so Clinkz can neither defend himself against Riki nor fight back effectively.
* It's hard to gank Riki as Clinkz has to find him first.
Pugna
* Heroes who are reliant on physical damage will be nullified by Decrepify: Riki, Wraith King, Juggernaut.
Clinkz
* Zeus can reveal Clinkz with 
Lightning Bolt.
* He is vulnerable to Zeus's magical nukes, due to his low health pool.
Pugna
* Even though Pugna's low HP means that he can be quickly burst down, his Nether Ward heavily punishes casters whose spells cost a lot of mana, like Zeus. Casting 4 of his active spells, including Nimbus, close to an enhanced level 4 Nether Ward, can make the ward deal up to 1750 magical damage.
* Decrepify can further increase the damage dealt by Nether Ward upon Zeus. However, if used on Pugna himself or on one of his allies, it will amplify the damage done by Zeus' abilities.
Pugna
* 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.
Clinkz
* Searing Arrows makes Clinkz one of the hardest heroes for Clockwerk to lane against.
Clinkz
* Searing Arrows and Clinkz physical damage items are almost suicidal when used on Legion Commander, as it invites an instant Duel and Legion Commander herself is a natural Blade Mail carrier.
* Duel locks down Clinkz for a long duration, preventing him from escaping with Skeleton Walk.
Pugna
* Decrepify on either hero stops Legion Commander from completing a Duel, and dissuades her from initiating Duels on ethereal allies.
* Life Drain can help Pugna's teammates win a fight, either by killing Legion Commander or replenishing her target's health.
Additional:
* Decrepify prevents Legion Commander from attacking allies during 
Duel, regardless if it's used on her or on the ally .
* Pugna can easily cast Decrepify, Nether Blast and Life Drain on Legion during the 4/4.75/5.5/8 seconds of duel
Clinkz
* 
Cold Embrace can heal herself or an ally, as well as protecting them from Clinkz's physical attacks and wasting his mana if Searing Arrows is on autocast.
* 
Winter's Curse allows Winter Wyvern to turn Clinkz's high damage and high attack speed against his allies, or take advantage of Clinkz's fragility if he can't use Skeleton Walk.
Pugna
* Cold Embrace is a death sentence against Pugna, since its the perfect setup for all his abilities, especially Life Drain.
* Decrepify can be cast to save the ally under Winter's Curse effect, wasting most of its duration.
* Winter Wyvern's abilities require a lot of mana, allowing Nether Ward to deal lots of damage.
Pugna
* 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.
Clinkz
* Invisibility reliant heroes: Heroes with invisibility abilities or those that have invested into invisibility items are hindered by Bounty Hunter's Track. Few examples of such heroes are:
Clinkz, 
Riki, 
Treant Protector, etc.
Track reveals Clinkz if he tries to escape with Skeleton Walk, allowing Bounty Hunter to gain lots of gold if he kills Clinkz.
Jinada with physical damage items can quickly kill Clinkz due to his low health.
