Vengeful Spirit
* Vengeful Spirit has no strong AoE nuke or disable against Phantom Lancer's Illusions.
* Phantom Lancer is a natural 
Diffusal Blade carrier, which reduces Vengeful Spirit's low mana pool very quickly, leaving her defenseless.
* 
Doppelganger can dodge Vengeful Spirit's abilites.
* 
Phantom Rush with his illusions can chase Vengeful Spirit efficiently.
Clockwerk
* Battery Assault's damage is dispersed against Phantom Lancer's illusions.
* Phantom Lancer can blink out of Power Cogs with Doppelganger.
* When chasing, a Phantom Lancer can close in with Phantom Rush and burn down Clockwerk's mana with Diffusal Blade, rendering him helpless before he has a chance to erect a defensive Power Cogs.
* Because Clockwerk does not like to buy items to deal with multiple enemies at once, like 
Battle Fury, 
Maelstrom and 
Mjollnir, he will be unable to deal with Phantom Lancer's illusions coming from 
Juxtapose.
Additional:
* Doppelganger. lets Phantom Lancer jump in and out of 
Power Cogs.
* Clockwerk's low mobility makes him an easy target for Phantom Lancer to rush on, and overwhelm with clones.
Vengeful Spirit
* Heroes who have a high mobility (
Queen of Pain, 
Storm Spirit, 
Slark, etc.).
Clockwerk
* 
Blink allows Quen of Pain to easily escape ganking or initiating attempts with Hookshot and Power Cogs.
Vengeful Spirit
* Skywrath Mage should have the upper hand against Vengeful Spirit with Ancient Seal.
* Vengeful is highly dependant on her abilities and has no natural means to deal against silences.
* Her low attack range allows Skywrath Mage to easily bully her out of the lane.
Clockwerk
* 
Skywrath Mage's 
Mystic Flare can deal huge damage to Clockwerk inside his Power Cogs.
Vengeful Spirit
* Heroes who have a high mobility (Queen of Pain, Storm Spirit, Slark, etc.).
Clockwerk
* Clockwerk lacks burst damage, and that makes him vulnerable to heroes who can recover themselves and turn the fight around to their advantage after Clockwerk finishes his initiation. Additionally, Clockwerk hates buying 
Dagon and 
Ethereal Blade, which are the only itmes that can help him deal with heroes who can recover themselves and turn the fight around to their advantage: 
Faceless Void, 
Terrorblade, 
Ursa, 
Weaver, 
Broodmother, Slark, 
Abaddon, 
Wraith King, 
Lifestealer.
Vengeful Spirit
* Heroes who relies on illusions and summons (
Beastmaster, 
Chaos Knight, etc.).
Clockwerk
* Single-target disablers will have difficulty locking down a Chaos Knight with Phantasm active: 
Bane, Beastmaster, 
Bloodseeker, 
Clockwerk, 
Doom, 
Shadow Shaman.
Vengeful Spirit
* Vengeful Spirit should carefully consider whether to use her Nether Swap on Tidehunter, as it can easily position him for a 
Ravage on Vengeful Spirit and her allies.
* Due to Magic Missile's high damage, 
Kraken Shell will often proc and clear Tidehunter's debuffs.
Clockwerk
* {U:Familiar}s can spot Clockwerk, allowing Visage's allies to dodge or block Hookshot attempts.
* Familiars will not be damaged by 
Blade Mail or Clockwerk's abilities, dealing dangerous amounts of damage to him.
Additional:
* Familiars can scout for Clockwerk's location allowing Visage to dodge or block 
Hookshot attempts.
* Gravekeeper's Cloak greatly absorbs damage from Hookshot.
Clockwerk
* 
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.
Clockwerk
* Clockwerk being confined in his own Power Cogs means Clockwerk is unable to quickly escape from Phoenix's 
Sun Ray and 
Supernova.
* Sun Ray will also heal the enemy Clockwerk is fighting, making it unlikely for Clockwerk to take an enemy down with him.
* For the same reasons, Phoenix also makes a powerful ally for Clockwerk when the situation is reversed.
Clockwerk
* Ember Spirit's 
Fire Remnant is an easy way to escape from Clockwerk's Power Cogs.
* 
Flame Guard blocks most of the magical damage Clockwerk does.
Clockwerk
* 
Purification does great damage to Clockwerk when fighting an enemy inside Power Cogs.
* Due to Clockwerk's very low damage output, Omniknight will have more than enough time to Purification and 
Heavenly Grace any enemy hero Clockwerk initiates on.
* For the same reasons, Omniknight also makes a powerful ally for Clockwerk when the situation is reversed.
Vengeful Spirit
* 
Nether Swap triggers extra damage from Rupture.
* Blood Rite sets up while Vengeful Spirit using her Nether Swap within a timed correctly.
Vengeful Spirit
* 
Vendetta disables Vengeance Aura and allows him to attack Vengeful Spirit with 
Impale and 
Mind Flare.
* 
Spiked Carapace is easy to use against a Wave of Terror or Magic Missile.
Clockwerk
* 
Searing Arrows makes Clinkz one of the hardest heroes for Clockwerk to lane against.
Vengeful Spirit
* 
Magic Missile is a solid damage source and lockdown that fits nicely with Rubick's kit.
* Rubick also acquires the secondary Magic Missile with 
Aghanim's Shard.
* 
Wave of Terror can be used to scout an area to prevent juking or initiate with 
Telekinesis, as well as reducing the armor of enemy team during a teamfight.
* Nether Swap does what it does - saving an ally from danger, initiating on an enemy, or helping with caughting a fleeing hero.
* With Aghanim's Shard, Rubick can lift himself up and drop quickly to a place of safety after the swap. Note that Rubick can only choose to either disable the enemy or save himself at one time with Telekinesis.
Additional:
* All of Vengeful Spirit abilities are very good for Rubick to 
Spell Steal:
* Magic Missile provides an additional nuke/disable to pair with 
Fade Bolt and Telekinesis, respectively.
* Wave of Terror serves as a good scouting/armor reduction skill that Rubick and his team can benefit from.
* Nether Swap complements Rubick's mobility and pairs well with other mobility items he usually builds. He can also use it to save an ally from danger.
Clockwerk
* 
Spirit Siphon can deal some serious damage to Clockwerk while he is in Power Cogs while healing Death Prophet in process. 
Exorcism can also be used to take down Clockwerk faster while he is in Power Cogs.
* Death Prophet usually buys a 
Hurricane Pike or 
Eul's Scepter of Divinity which allows her to easily escape from Power Cogs or save her allies from Clockwerk.
* 
Silence can prevent Clockwerk from using his ablities during teamfight, especially since Clockwerk is an easy target for it while in Power Cogs.

Clockwerk
* Shadow Fiend usually buys a Hurricane Pike allowing him to easily escape from Power Cogs.
* Shadow Fiend can farm Clockwerk's Power Cogs to gain Necromastery stacks.
Vengeful Spirit
* 
Nethertoxin disables Vengeance Aura.
* Vengeful Spirit has no mobility spells aside from Nether Swap, which Viper can take advantage of with his slows.
* Viper can easily bully Vengeful Spirit out of a lane with 
Poison Attack.
Additional:
* 
Viper Strike can disable the attack damage bonus from 
Vengeance Aura and the components of Nether Swap.
* Both Magic Missile and Wave of Terror are counteracted by 
Corrosive Skin, making Vengeful Spirit's fighting harder against Viper.
Vengeful Spirit
* 
Ball Lightning disjoints an incoming Magic Missile, avoids Wave Of Terror, and allows Storm Spirit to easily escape if he ever gets Nether Swapped.
Clockwerk
* 
Waveform allows Morphling to easily escape Power Cogs.
* Clockwerk's lack of burst damage makes it nearly impossible for him to kill a Morphling using 
Attribute Shift (Strength Gain).
Additional:
* Morphling can escape from Power Cogs with Waveform.
* Even if Morphling is trapped in Power Cogs, Morphling can use Attribute Shift (Strength Gain) to survive the duration.
Clockwerk
* Clockwerk lacks burst damage, and that makes him vulnerable to heroes who can recover themselves and turn the fight around to their advantage after Clockwerk finishes his initiation. Additionally, Clockwerk hates buying Dagon and Ethereal Blade, which are the only itmes that can help him deal with heroes who can recover themselves and turn the fight around to their advantage: Faceless Void, Terrorblade, Ursa, Weaver, Broodmother, Slark, Abaddon, Wraith King, Lifestealer.
Clockwerk
* 
Ancient Apparition's 
Cold Feet will freeze Clockwerk in place if he stays inside his Power Cogs. His immobility while in his cogs also makes him a very easy target to 
Ice Vortex and 
Ice Blast.
Clockwerk
* Heroes that have a weak laning stage: 
Spectre, 
Nyx Assassin, Clockwerk, 
Spirit Breaker, 
Omniknight, 
Pudge.
Clockwerk

Vengeful Spirit
* Frail heroes who lacks mobility: 
Crystal Maiden, 
Enigma, 
Dark Willow, 
Vengeful Spirit.
Vengeful Spirit
* Heroes who relies on illusions and summons (Beastmaster, Chaos Knight, etc.).
Clockwerk
* With 
Feast and 
Rage, Lifestealer is nearly impossible for Clockwerk to bring down, and is the last hero Clockwerk wants to be trapped with in Power Cogs.
Vengeful Spirit
* With the exception of Magic Missile (unless the player takes the Level 25 Talent "Magic Missile Pierces Spell Immunity"), all of Vengeful Spirit's spells ignore Spell Immunity. This also makes her good against heroes with built-in Spell Immunity like Lifestealer or 
Juggernaut or heroes that tend to pick up 
Black King Bar, like 
Sven.
Clockwerk
* Aghanim's Shard upgraded 
Poison Touch can be used to hex Clockwerk, silencing him, disarming him, slowing him, and muting him, and thus rendering him unable to use Blade Mail to return damage or to do anything at all.
* 
Shadow Wave will hit Clockwerk every time when he's fighting with an enemy inside Power Cogs.
* Due to Clockwerk's very low damage output, Dazzle will have more than enough time to 
Shallow Grave any enemy hero Clockwerk initiates on.
Additional:
* Shadow Wave will hit Clockwerk every time when he's fighting with an enemy inside Power Cogs.
* Due to Clockwerk's steady damage output, Dazzle has plenty of time to Shallow Grave anyone Clockwerk initiates on.
Clockwerk
* Some heroes with extreme range, like 
Zeus, 
Invoker or Clockwerk, can snipe your allies from anywhere after your Grave has expired.
Clockwerk
* Juggernaut is invulnerable while using 
Omnislash, meaning that neither Blade Mail or Power Cogs will save Clockwerk, this is especially common during the early laning phase.
* 
Blade Fury will also ignore any damage dealt by Battery Assault, as well as dealing heavy damage. As long as Juggernaut has mana to cast it.
* Overall, any attempt for Clockwerk to trap Juggernaut with Power Cogs will hurt him a lot more than the other way around.
Vengeful Spirit
* With the exception of Magic Missile (unless the player takes the Level 25 Talent "Magic Missile Pierces Spell Immunity"), all of Vengeful Spirit's spells ignore Spell Immunity. This also makes her good against heroes with built-in Spell Immunity like Lifestealer or Juggernaut or heroes that tend to pick up Black King Bar, like Sven.
Clockwerk
* Clockwerk cannot go head-to-head with Huskar in Power Cogs, as 
Berserker's Blood and 
Life Break will destroy him faster than the other way around.
Additional:
* Clockwerk's abilities cannot handle Huskar in a one-on-one fight, even if he gets the jump on him.
Vengeful Spirit
* Heroes with abilities that reduce armor will make Huskar very vulnerable: Weaver, 
Dazzle, 
Bristleback, Vengeful Spirit.
Additional:
* Huskar struggles against heroes that output high physical damage due to his low armor. Vengeful Spirit's Wave of Terror and Vengeance Aura help increase the physical damage of her team.
Clockwerk
* Ursa's high physical burst damage combined with his big attack speed and durability makes him a very bad target for Power Cogs.
* Even with Blade Mail, Ursa's 
Enrage will negate most of the reflected damage.
Clockwerk
* Heroes who can provide constant vision inside the Roshan Pit can negate one of the strongest advantages of Ursa, which is the possibility of quickly killing Roshan at the early game, with minimum itemization needed (Clockwerk, Beastmaster, etc).
Clockwerk
* 
Firesnap Cookie can be fed to Snapfire herself or to an ally caught inside Power Cogs.
* A badly placed Power Cog makes it easier for Snapfire to aim 
Mortimer Kisses on Clockwerk
Clockwerk
* 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.
Clockwerk
* 
Conjure Image and 
Reflection illusions may give Clockwerk a hard time to find an angle for Hookshot.
* Because Clockwerk lack burst damage, Terrorblade can often save himself with 
Sunder.
Vengeful Spirit
* Heroes with abilities that can lock down Terrorblade and prevent him from using Sunder: Bane, 
Batrider, 
Earthshaker, 
Elder Titan, Faceless Void, Invoker, 
Legion Commander, 
Mars, 
Primal Beast, 
Riki, Shadow Shaman, 
Silencer, Vengeful Spirit, 
Void Spirit.
Vengeful Spirit
* Lina can burst Vengeful Spirit down, provided she can land 
Light Strike Array before Vengeful Spirit lands her Magic Missile.
* 
Laguna Blade deals massive damage, often being enough to kill a squishy Vengeful Spirit.
Vengeful Spirit
* Heroes with abilities that can pull Lina out of position can easily bring her to their team mates, like Batrider with 
Flaming Lasso, Pudge with 
Meat Hook and Vengeful Spirit with Nether Swap.
Vengeful Spirit
* Wave of Terror grants flying vision over trees, and its wide effect can hit Monkey King and end Mischief.
* Nether Swap can easily cancel Wukong's Command by swapping him out of the circle.
Additional:
* She can easily cancel 
Wukong's Command with Nether Swap.
* Wave of Terror can also detect him while he's on the trees.
Clockwerk
* Power Cogs pushes Monkey King out of Wukong's Command, ending his ultimate.
* Rocket Flare allows Clockwerk to scout Monkey King in the trees, and chase him with Hookshot.
Vengeful Spirit
* Vengeful Spirit can interrupt Black Hole's channeling through Black King Bar by using Nether Swap from a safe distance.
* Vengeful Spirit's Level 25 Talent can make her Magic Missile pierce spell immunity, giving her another option to use in conjunction with Nether Swap to cancel Enigma's Black Hole channeling even through both, Black King Bar and 
Linken's Sphere.
Clockwerk
* 
Black Hole requires channelling, making it easy to be interrupted with Hookshot.
* Enigma lacks mobility without a Blink Dagger and also is squishy, making him fall easily when ganked by Clockwerk.
Additional:
* Hookshot's stun pierces through spell immunity and Enigma's channeling can be easily cancelled from a safe distance, assuming none of his allies are in the way, and the Black Hole is not centered directly on Enigma.
Vengeful Spirit
* Wave of Terror can reveal a Tinker attempting to hide in the trees and then Nether Swap and Magic Missile will both serve to interrupt/lock him down, should he attempt to town portal or reload.
Clockwerk
* Rocket Flare can find Tinker if he blinks into the treeline, and Hookshot will prevent him from teleporting out.
* Battery Assault makes Tinker unable to 
Rearm by stunning him repeatedly.
Additional:
* Clockwerk can easily catch a split pushing Tinker with his Hookshot and prevent him from escaping with Power Cogs and 
Battery Assault. Clockwerk can also find a Tinker hiding in trees with his 
Rocket Flare.
* Clockwerk usually buys a Blade Mail, which does lots of damage to Tinker if he gets hit by his abilities (especially March of the Machines).
Vengeful Spirit
* Heroes with strong channeling spells like Crystal Maiden's 
Freezing Field, Bane's 
Fiend's Grip, and Enigma's Black Hole can easily be interrupted from a long range by Nether Swap, assuming they don't have a Linken's Sphere.
Clockwerk
* Battery Assault, Power Cogs, and Hookshot can interrupt Freezing Field, the latter two being able to go through invisibility should Crystal Maiden use 
Glimmer Cape.
* Rocket Flare can be used to find Crystal Maiden should she try to hide in the trees to try to safely cast Freezing Field.
* Hookshot allows Clockwerk to easily close in on Crystal Maiden and kill her.
Vengeful Spirit
* Heroes with catch to disrupt Sniper's positioning and deliver him into the enemies: Batrider, 
Disruptor, Pudge, Vengeful Spirit.
Clockwerk
* Clockwerk is also the least optimal target for Sniper to attack in a teamfight, although more experienced players will rarely make this mistake.
* With no mobility or disable skills, getting trapped in Power Cogs is a death sentence for Sniper.
Vengeful Spirit
* With Nether Swap, Vengeful Spirit can isolate one of the Meepos, making him an easier kill for the team.
* Her Magic Missile gives her an easy way to cancel Meepo's 
Poof, preventing isolated Meepos from fleeing.
Clockwerk
* Because only one clone needs to be killed in order to kill Meepo, heroes that excel at singling out enemies can also be a detriment to him, such as Batrider, Beastmaster, Pudge and Clockwerk.
Vengeful Spirit
* Nether Swap breaks Flaming Lasso when used on ally and can break if used on Batrider.
* Vengeful Spirit can disable Batrider's 
Blink Dagger before a fight with Wave of Terror.
Additional:
* With her Nether Swap, Vengeful Spirit can save the life of an ally who gets caught with Flaming Lasso. Nether Swap also makes it highly dangerous for Batrider to attempt a lasso, as it can lead to his own demise far behind enemy lines.
* Wave of Terror's flying vision allows Vengeful Spirit to spot Batrider trying to close in on his target with 
Firefly.
Vengeful Spirit
* Nether Swap can forcibly reposition 
Sharpshooter.
Clockwerk
* Power Cogs prevent Windranger from fleeing with 
Windrun.
* Battery Assault repeatedly interrupts 
Focus Fire, disrupting Windranger's damage output.
Additional:
* Windranger cannot escape with Windrun when she is trapped inside Power Cogs.
* Battery Assault repeatedly interrupts Focus Fire, disrupting Windranger's damage output.
Clockwerk
* Meat Hooking a Clockwerk can backfire for Pudge, as Battery Assault and Blade Mail will hurt Pudge more than he hurts Clockwerk.
Clockwerk
* Battery Assault easily interrupts Centaur Warrunner due to his poor cast animation.
* Power Cogs can negate Stampede.
Clockwerk
* Clockwerk's Battery Assault disables Earth Spirit's Rolling Boulder, while his Power Cogs ensure, that Earth Spirit can't move away from it.
* His Hookshot allows him to chase after Earth Spirit, while using Rocket Flare to gain vision.
Vengeful Spirit
* Nether Swap breaks one ally out of Soulbind, and can be used to redistribute the shared damage to Vengeful Spirit herself.
Clockwerk
* Clockwerk's long range initiation and catch makes it incredibly difficult for Nature's Prophet to split push and show on the map alone.
* Rocket Flare can be used to scout Nature's Prophet if he is hiding in the forest, and can provide vision inside of Sprout.
Vengeful Spirit
* Vengeful Spirit has two abilities to interrupt Death Ward, even through Black King Bar.
Clockwerk
* Battery Assault will continuously interrupt Earthshaker's long cast animations.
* Power Cogs can also trap Earthshaker after he initiates.
Additional:
* Battery Assault interrupts Earthshaker's long cast animations, preventing him from using any abilities apart from Echo Slam.
* Power Cogs often separate the battlefield so that both enemies and allies are unlikely to cluster.
* Rocket Flare allows Clockwerk to scout Earthshaker before a fight starts and potentially cancel his Blink Dagger.
* Hookshot enables Clockwerk to catch Earthshaker before he gets a chance to initiate a fight.
Clockwerk
* 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.
Clockwerk
* Getting trapped in Power Cogs usually means the end for Drow Ranger.
Additional:
* Hookshot lets Clockwerk close the gap to Drow Ranger, disabling her Marksmanship bonus.
* Power Cogs and Battery Assault keep Drow Ranger from escaping.
* Power Cogs and Battery Assault also keep Drow Ranger close, nullifying Marksmanship.
Clockwerk
* Battery Assault's mini-stuns can severely disrupt Legion Commander's attack animation when she enters a 
Duel, potentially saving Clockwerk (or his allies) and possibly even giving him an edge in securing a win himself.
* Power Cogs pushes Legion Commander away from Clockwerk's allies when she enters a Duel.
Clockwerk
* Battery Assault's continuous mini-stun makes it hard for Elder Titan to cast his spells due to his poor cast animation.
* Elder Titan's channelling with Echo Stomp makes a good setup for Hookshot if timed correctly.
Clockwerk
* Heroes with long cast animations can be continuously interrupted by Battery Assault: 
Centaur Warrunner, 
Jakiro, 
Leshrac, 
Naga Siren, 
Underlord.
Clockwerk
* Heroes with nukes that can jump her: Clockwerk, 
Snapfire, Spirit Breaker, 
Techies
Vengeful Spirit
* Heroes with disables that ignore spell immunity will render Phantom Assassin completely useless in teamfights throughout the game: 
Axe, Enigma, Vengeful Spirit, Doom, Bane, Beastmaster, Pudge, 
Medusa, 
Warlock.
Clockwerk
* Every hero that can withstand or prevent Eclipse at level 7: Juggernaut, Riki, Clockwerk, 
Drow Ranger, Abaddon, Faceless Void, Weaver, 
Outworld Destroyer.
Vengeful Spirit
* Certain heroes can mess up with Pangolier's positioning and timing (especially if he intends to use Rolling Thunder during combat): Vengeful Spirit, 
Keeper of the Light, 
Huskar, 
Dark Seer
Vengeful Spirit
* Heroes with high physical and magical damage alike are a huge hazard for Muerta, as they can deal serious damage to her even if she has 
Pierce the Veil active: 
Luna, 
Lina, 
Tusk, Broodmother, 
Shadow Fiend, 
Ember Spirit, 
Gyrocopter, Vengeful Spirit, 
Arc Warden, Medusa, Shadow Shaman.
Vengeful Spirit
* Fragile supports who die in a few hits against Sven's high physical damage: Crystal Maiden, Vengeful Spirit, Dark Willow.
Vengeful Spirit
* With the exception of Magic Missile (unless the player takes the Level 25 Talent "Magic Missile Pierces Spell Immunity"), all of Vengeful Spirit's spells ignore Spell Immunity. This also makes her good against heroes with built-in Spell Immunity like Lifestealer or Juggernaut or heroes that tend to pick up Black King Bar, like Sven.
Clockwerk
* Heroes who can stun Sven even with an activated Black King Bar can be an issue: Clockwerk, Beastmaster.
Clockwerk
* Heroes with long cast animations can be continuously interrupted by Battery Assault: Centaur Warrunner, Jakiro, Leshrac, Naga Siren, Underlord.
Clockwerk
* Heroes who can stop Axe from getting close will severely inhibit his presence in fights: Bristleback, Crystal Maiden, Batrider, Arc Warden, 
Winter Wyvern, Clockwerk
Clockwerk
* Heroes with long cast animations can be continuously interrupted by Battery Assault: Centaur Warrunner, Jakiro, Leshrac, Naga Siren, Underlord.
Additional:
* Clockwerk naturally builds Blade Mail, reflecting Leshrac's high magic damage output back at him.
* Power Cogs will prevent Leshrac from reaching Clockwerk's team and dealing large AOE damage to them.
* Power Cogs will also keep Leshrac close, wasting his Diabolic Edict on just Clockwerk.
* Battery Assault interrupts Leshrac's long cast times of Split Earth and Lightning Storm.
Clockwerk
* Heroes with long cast animations can be continuously interrupted by Battery Assault: Centaur Warrunner, Jakiro, Leshrac, Naga Siren, Underlord.
Additional:
* Battery Assault prevents Jakiro from casting spells as all his spells have very long cast times.
* Jakiro is also an easy target for Clockwerk's Hookshot + Power Cogs combo, as he has little mobility and no escape without items.
* Alternatively, if the enemy Clockwerk traps one of his own allies or Jakiro's allies in the cogs, it gives Jakiro an ideal setup to punish Clockwerk and his ally or to save Jakiro's ally, respectively.
Clockwerk
* Heroes with long range abilities are also able to touch Zeus, such as Clockwerk, 
Kunkka, 
Puck, Skywrath Mage, Spirit Breaker, Tusk and others.
Vengeful Spirit
* Heroes with strong channeling spells like Crystal Maiden's Freezing Field, Bane's Fiend's Grip, and Enigma's Black Hole can easily be interrupted from a long range by Nether Swap, assuming they don't have a Linken's Sphere.
Clockwerk
* Clockwerk lacks burst damage, and that makes him vulnerable to heroes who can recover themselves and turn the fight around to their advantage after Clockwerk finishes his initiation. Additionally, Clockwerk hates buying Dagon and Ethereal Blade, which are the only itmes that can help him deal with heroes who can recover themselves and turn the fight around to their advantage: Faceless Void, Terrorblade, Ursa, Weaver, Broodmother, Slark, Abaddon, Wraith King, Lifestealer.
Vengeful Spirit
* Nether Swap can save an ally from the Chronosphere.
Additional:
* With her Nether Swap, a well positioned Vengeful Spirit can save the life of a more important ally who gets caught in 
Chronosphere.
Clockwerk
* Due to Clockwerk's slow damage output, Chen can often save a trapped ally with Hand of God.
* Clockwerk does not have any source of damage to deal with Chen Creeps.
* Chen can use his creeps to block Clockwerk's attempts to use Hookshot.
Additional:
* Due to Clockwerk's very low damage output, Chen can often save a trapped enemy hero with 
Hand of God.
* 
Penitence's attack speed amplification allows Chen and his allies to kill Clockwerk quickly after his initiation.
* Chen's creeps can be used to block Hookshot initiation from all sides, as well as distribute Battery Assault's damage.
Vengeful Spirit
* Magic Missile can stun Chen and deal heavy damage to him.
* Wave of Terror weakens durability of Chen and his creeps.
* Nether Swap can be used to separate Chen away from his creeps, often to certain death from Vengeful Spirit's allies.
Vengeful Spirit
* Magic Missile has a considerably long cast time, making it difficult to stop 
Charge of Darkness with it.
* Other than Magic Missile, Vengeful Spirit has no way of canceling 
Nether Strike.
Clockwerk
* Clockwerk can use Power Cogs to repel Spirit Breaker when he charges in with Charge of Darkness.
* Spirit Breaker's slow 0.6 second attack animation attacks do little damage against Clockwerk. It can also constantly be interrupted by Battery Assault.
* Nether Strike's 1.2 second charge time gives Clockwerk plenty of time to activate Blade Mail and for Battery Assault to cancel it.
Additional:
* Battery Assault will continuously prevent Spirit Breaker from using Nether Strike, Charge of Darkness and even right clicking because of his slow base attack speed.
Vengeful Spirit
* Past the mid game, an isolated Vengeful Spirit makes for an easy kill for Anti-Mage.
Blink away to disjoint the stun or reflect it back against Vengeful Spirit with 
Counterspell.
* Magic Missile is the only disable Vengeful Spirit has against Anti-Mage, but he can either
* Nether Swap isn't very effective against Anti-Mage - if used offensively, Anti-Mage can simply blink away to safety, and if used defensively, Blink's low cooldown allows him to persistently chase as well.
Clockwerk
* Anti-Mage can Blink into or out of
Power Cogs, negating Clockwerk's initiation and bypassing his defenses.
Blink out of Power Cogs, escaping any ganking or initiation attempts.
Mana Break depletes Clockwerk's much-needed mana.
Counterspell makes Clockwerk's very low damage output only tickle Anti-Mage.
Additional:
* Anti-Mage can easily

*
