* Glimpse and Kinetic Field allows Disruptor to set up some early kills onto Shadow Fiend.
* Static Storm can be used to cancel the cast of Requiem of Souls.

* 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.
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.

* Nether Blast will still hit Slark in Shadow Dance.
* Pugna can rarely target Slark directly with Decrepify, but he can 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.

* Thunder Strike provides vision on him while Slark is invisible.
* Glimpse's range at lvl 3-4 is more than enough to pull him back to a favorable position for your team to group up and kill him.
* Even though he is capable of picking you off and deal enough damage to kill you, Slark will be literally sticking his neck out, since jumping on Disruptor means being on his battleground.
* AoE silence and the ability to mute Black King Bar is deadly to Slark at all stages of the game.
Additional:
* Static Storm and Kinetic Field locks down Slark, as he cannot use Dark Pact to dispel any disables, or Pounce out while silenced.
* Glimpse puts an end to any attempts at ganking Disruptor or his allies, and also negates Slark's mobility by bringing him back into the fight if he tries to escape with Pounce.

* Disruptor can control where she goes with Kinetic Field and Glimpse. Static Storm shuts her down in teamfights.

* 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.

* Disruptor can disable Magnus's Blink Dagger using Thunder Strike during a considerable duration, disrupting his initiation attempts.
* Glimpse brings Magnus back after he escapes with Skewer and/or Force Staff.
* Static Storm if used on a fight can prevent Magnus from using Reverse Polarity after he jumps in.

* 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.

* 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.

* As a spellcaster, silences will nullify him entirely. Some notable examples are Death Prophet, Drow Ranger, Bloodseeker, Disruptor and many others.
* Doom, as usual, fits this description nicely.

* Heroes that can apply early pressure before Phantom Assassin has farm are massive threats: Axe, Viper, Meepo, Pugna, Slark etc.

* Doom, Disruptor with Aghanim's Scepter, and hex abilities all prevent item usage, which is a severe problem for Phantom Assassin as it prevents her from using Black King Bar, the one item that helps protect her against the aforementioned dangers. Doom and Shadow Demon with Aghanim's Scepter also disables Phantom Assassin's Evasion and Critical Strike, removing much of her damage and survivabaility.

* 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.

* 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

* Thunder Strike provides vision of Monkey King when he's in the trees. The periodic damage will also keep Monkey King from using Tree Dance if he's on the ground.
* Glimpse pulls Monkey King out of the trees if he attempts to escape using Tree Dance, and can cause Wukong's Command to end prematurely if Monkey King is Glimpsed out of its radius.
* However, if Monkey King strikes first, if he has already casted Wukong's Command, Disruptor's abilities will not be much of an use

* 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.

* Thunder Strike gives vision of Queen of Pain when she's trying to escape. When combined with Glimpse, her mobility and hit-and-run style can be negated.
* While in a team fight, Static Storm forces Queen of Pain to only use right-clicks.
* When combined with the Kinetic Field, she can only wait until she respawns.
Additional:
* Blink and positioning is crucial for Queen of Pain. These factors are heavily countered by a good Glimpse.
* Static Storm is devastating for Queen as she relies heavily on her spells to inflict heavy burst damage.

* 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.

* 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.

* 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.

* 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.

* 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.
Additional:
* 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.

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

* Glimpse drags Spirit Breaker back from an escaping Charge, or takes him out of a ganking Charge.
* However, after purchasing Aghanim's Shard, a well-timed Nether Strike will completely nullify the Glimpse during a gank attempt.
* Static Storm can be used to instantly stop his charge if absolutely necessary, and also prevent a follow-up Nether Strike.

* 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

* 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.

* Disruptor can always Glimpse back Io or his target after he Relocated nearby.
* Even better, thanks to the indicator on the ground, you can even preemptively drop Static Storm and Kinetic Field on the spot they will relocate to.
* Thunder Strike and Glimpse are also good tools to bring back an Io that Tethered away in the fog of war.
Additional:
* Glimpse directly negates Relocate.

* Pugna can save allies with both healing or by making them ethereal but needs to be careful of Sven's Aghanim's Scepter purge.

* Kinetic Field prevents Dawnbreaker from escaping with Celestial Hammer.
* Kinetic Field and Static Storm can pin down Dawnbreaker after she jumps in with Solar Guardian.
* Glimpse can force Dawnbreaker out of a fight right after she uses Solar Guardian.

* 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 you at all.

* Glimpse will return Underlord or any of his teammates attempting to escape with Dark Rift if timed correctly.
* Underlord is a slow and low mobility hero, easy to set up Static Storm and Kinetic Field, preventing him from using his abilities as well as preventing him using Dark Rift to escape

* 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
Additional:
* 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.

* Kinetic Field and Glimpse can completely negate Stampede.

* 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.

* 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.

* In the mid-game, Tidehunter relies on Kraken Shell to stay alive and get his Ravage off. Apart from Thunder Strike, none of Disruptor's abilities can be dispelled, so it's rather easy to trap him inside Kinetic Field and Static Storm.
* Be mindful, however, that Kraken Shell still makes Tidehunter very tanky, so be sure that you can kill him with your combo or your partners while he is silenced and trapped.

* Arc Warden can't use Magnetic Field to stall the damage of Nether Blast on towers, but he can buy Aghanim's Shard 20 minutes into the game 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.

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

* Nether Ward will be problematic for heavy nukers and spammers like Skywrath Mage, Lina, Lion and Invoker, but don't use Decrepify defensively against them as you'll be helping them out more than anything.

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

* 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.

* 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.

* Heroes with mana burn: Nyx Assassin, Invoker, Outworld Destroyer, Pugna

* At around the 10-minute mark, Disruptor would normally be level 6 or 7. This means you can have a level 3/4 glimpse along with Static Storm. A high level glimpse is enough to pull Storm back to a Static Storm even after he used Ball Lightning due to his limited mana pool at that time.
* Be careful in the late game however, as there is a good chance he will kill you straight-out before Glimpse has finished bringing him back. Therefore Glimpse would simply bring him back to safety after he's murdered you or a teammate. Of course, this is assuming he hasn't silenced you with an item.

* Nether Ward will be problematic for heavy nukers and spammers like Skywrath Mage, Lina, Lion and Invoker, but don't use Decrepify defensively against them as you'll be helping them out more than anything.

* Heroes that can negate Hoodwink's mobility: Kunkka, Disruptor, Mars.

* Dark Seer relies on Surge for most of his mobility, so he's not very vulnerable to slows, but much more to root effects and walls or pseudo-walls such as Disruptor's Kinetic Field or Slark's Pounce.

* Any heroes with high intelligence, such as Invoker and 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.

* 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.

* Heroes that can punish aggressive heroes, such as: Leshrac, Shadow Demon, Pugna, Death Prophet.

* Heroes that can keep Marci for a long time in one place so she can't pursue her targets, like Bane, Lion, Shadow Shaman, Invoker, Disruptor and Kunkka.

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

* 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.

* Thunder Strike can be used to cancel Earthshaker's Blink Dagger.
* Glimpse brings Earthshaker back after he jumps on Aghanim's Scepter upgraded Enchant Totem.
* Static Storm if used on a fight can prevent Earthshaker from executing his combo after blinking in.

* 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.

* Riki and Disruptor: Smoke Screen and Static Storm can be thrown wherever Puck used Phase Shift, making Puck an easy target if it doesn't have Blink Dagger or is on cooldown. Puck is also very susceptible to Riki's high attack damage when attacking from the back. Glimpse also prevents Puck from escaping.

* Pugna's Nether Ward damages Sand King when he channels Epicenter, preventing him from using Blink Dagger afterward.

* Glimpse can simply send Primal Beast back after using Onslaught to close the gap.
* While Static Storm is not much of a threat in terms of damage, it does prevent Primal Beast from casting any spells.
* Kinetic Field can prevent Primal Beast from leaving a specified area.
* Overall, Disruptor forces Primal Beast to buy a Black King Bar much earlier than he might like but becomes a major threat to Disruptor once he does.

* Glimpse moves Clockwerk away from allies struck by Hookshot, or under attack by Battery Assault.
* Static Storm can turn Power Cogs into Clockwerk's own grave, and if Disruptor has Aghanim's Scepter, then Clockwerk will not be able to use Blade Mail to return damage at all.

* 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.

* Glimpse brings Anti-Mage back after he Blinks away.
* Static Storm stops Anti-Mage from Blinking.
Additional:
* Similar to Queen of Pain, Glimpse can disable Blink, negating his mobility.
* However, Counterspell can negate a majority of Disruptor's damage, which may require him to have a partner to successfully kill Anti-Mage.

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