* 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 does not have any passive abilities at all, making Nethertoxin nearly useless.
* Viper's Corrosive Skin cannot protect him from Clinkz's combined attack from Strafe, Searing Arrows, Burning Army and Orchid Malevolence.
Additional:
* 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.

* 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).

* Heroes that can pick you off: Clinkz, Nyx Assassin, Puck, Riki.

* 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

* 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.

* Heroes that can instantly kill creeps greatly reduce the effectiveness of Chen's converted army: Lifestealer, Doom, Mirana, Clinkz.

* Heroes with damage burst can often kill Chen or his allies before he can use Hand of God: Lina, Techies, Shadow Fiend, Pugna, Nyx Assassin.

* Clinkz can use Burning Army in teamfights which will cause a problem for Alchemist.

* 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.

* 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 has attack range talent can also outrange Plague Ward.

* 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 has attack range talent can also outrange Plague Ward.

* Strafe and Searing Arrows allow Clinkz to quickly kill Io due to its low armor.

* 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.

* 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 against Shadow Demon's abilites.
* However it can be cancelled by Disruption, until Pugna buys defensive items.

* For the better part of the game, he will take more damage from your ward than he deals to you with Arcane Orb.
* It will take a huge difference in farm or itemization between you for him to deal any damage to you with Sanity's Eclipse, provided he doesn't die first from casting it next to your ward.
* Decrepify allows Pugna to be immune to the attacks from Arcane Orb.

* Clinkz's high damage output and insane attack speed late-game can take Kunkka out of the fight before it begins.
* Strafe 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 relies heavily on the physical damage provided by Searing Arrows, which completely overrides the capabilities of Rage.
* Open Wounds is near worthless against Clinkz as he can instantly run away with Skeleton Walk before returning later on.
* Clinkz, by nature will often build items that Lifestealer hates dealing with such as physical damage items like Desolator or Daedalus and instant silences or hexes from Bloodthorn and Scythe of Vyse.

* Nether Ward will cause an unfriendly area for Medusa, draining her mana.

* Considering Rubick's abysmal armor, Rubick is a squishy target for Clinkz to gank. 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.

* 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 spamming 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 and his Shadowraze.

* 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.
Additional:
* 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.

* 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.

* 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
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.
* Decrepify can further increase all the magical damage done to Timbersaw, bypassing the enhanced physical resistance he can get from Reactive Armor.

* Decrepify turns the target ethereal, protecting them from Chaos Knight's and his illusions' attacks.
* Life Drain instantly destroys illusions. It can effectively negate Phantasm when upgraded with Aghanim's Scepter.
* Nether Blast quickly clears out illusions and can harass Chaos Knight in lane.

* 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.

* Pugna can save allies with both healing or by making them ethereal.

* 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.

* Heroes that can jump and kill him: Meepo, Clinkz, Templar Assassin

* Heroes with invisibility: (Riki, Clinkz, Nyx Assassin

Additional:
* 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.

* Since Life drain takes out illusions instantly, Pugna with a scepter is decent versus plenty of illusion heroes, most notably Naga Siren and Terrorblade and the aforementioned Chaos Knight. Phantom Lancer is an exception.

* Due to Tiny's non-existent agility gain, high physical damage heroes are more effective against him (Clinkz, Phantom Assassin, Templar Assassin, Ursa, Wraith King etc).

* 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.

* Ethereal state disarms the target and makes them more vulnerable to magic damage, both of which Phantom Assassin despises. Especially Pugna and any hero that is wielding Ethereal Blade, such as Mirana, Nyx Assassin or Morphling.

* Since Life drain takes out illusions instantly, Pugna with a scepter is decent versus plenty of illusion heroes, most notably Naga Siren and Terrorblade and the aforementioned Chaos Knight. Phantom Lancer is an exception.

* 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.

* 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.

* 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.

* 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.

* Heroes who can harass Omniknight out of lane will keep him weak in the mid game: Viper, Venomancer, Clinkz

* Pugna: Decrepify prevent the Spirit bear from attacking or protect allies from it.

* 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'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.

* Heroes with abilities that can save are also effective such as Shadow Demon, Dazzle, Oracle, Bane, Pugna, Tusk, Winter Wyvern, Io, Underlord, Treant Protector and Keeper of the Light.

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.

* Heroes who are reliant on physical damage will be nullified by Decrepify: Riki, Wraith King, Juggernaut.

* Heroes with good escapes can usually outmaneuver and escape from Spectre: Slark, Clinkz, Weaver

* 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.

* Nether Ward discourages Tinker from using abilities and items due to its high damage against heavy mana usage.

* Nether Blast, Decrepify and Life Drain deals 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 his heavy mana cost on Arena Of Blood.
* Pugna is one of few heroes that can contest Mars' ability to push and defend towers early on.

* 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.

* 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 you at all.
Additional:
* 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.

* Decrepify prevents Faceless Void from attacking trapped allies inside Chronosphere, wasting a large portion of its duration if Faceless Void can't dispel it.

* 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.

* Heroes with a high degree of mobility and invisibility are hard to catch with Meat Hook: Ember Spirit, Riki, Clinkz, Queen of Pain.

* 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.

* Heroes with invisibility and high mobility can jump on and focus down Earthshaker before he has a chance to initiate: Clinkz, Slark, Storm Spirit

* 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.

* 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

* 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.

* Searing Arrows makes Clinkz one of the hardest heroes for Clockwerk to lane against.

* 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.
