Shadow Shaman
* 
Waveform allows Morphling to escape from Mass Serpent Ward
* Morphling can interrupt Shadow Shaman while he is shackling an ally with 
Adaptive Strike (Strength).
* With 
Ethereal Blade Morphling can quickly burst him down before he even has a chance to react.
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.
Shadow Shaman
* 
Omniknight can dispel Hex or Shackles with 
Heavenly Grace. He can also heal teammates who you disabled. The same goes for 
Abaddon's 
Aphotic Shield.
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.
Shadow Shaman
* 
Reincarnation allows Wraith King to survive Shadow Shaman's initial chain of disables and Serpent Ward attacks.
* Short cooldown of 
Wraithfire Blast is ideal for interrupting Shackles.
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.
Shadow Shaman
* With 4 active abilities, Shadow Shaman is weak against silencing foes such as 
Silencer, 
Drow Ranger and 
Death Prophet.
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.
Additional:
* 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.
Shadow Shaman
* By simply using Aphotic Shield, Abaddon can easily save his allies from heroes that apply long disables, such as 
Lion or 
Shadow Shaman.
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.
Shadow Shaman
* Support heroes with low mobility can be slowed further by Incapacitating Bite, and swarmed by Spiderlings for an easy kill: Shadow Shaman, 
Visage, 
Dazzle, 
Rubick, 
Lich.
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.
Shadow Shaman
* 
Nyx Assassin, 
Bounty Hunter and Slark can all sneak up and kill Shadow Shaman, Nyx being particularly deadly. Shadow Shaman must watch out for Slark carefully, as he can break either (but not both unless he makes a mistake) of Shadow Shaman's disables, with 
Dark Pact and leap out of a serpent ward ring. These heroes, however, rely heavily on escape and are themselves not very durable and none of them can survive a full lockdown with Mass Serpent Ward. Having Sentry Wards can turn Shadow Shaman from prey to predator.
Clockwerk

Shadow Shaman
* Single-target disablers will have difficulty locking down a Chaos Knight with Phantasm active: 
Bane, 
Beastmaster, 
Bloodseeker, 
Clockwerk, 
Doom, Shadow Shaman.
Clockwerk
* Single-target disablers will have difficulty locking down a Chaos Knight with Phantasm active: Bane, Beastmaster, Bloodseeker, Clockwerk, Doom, Shadow Shaman.
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
* 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.
Clockwerk
* 
Searing Arrows makes Clinkz one of the hardest heroes for Clockwerk to lane against.
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.
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.
Shadow Shaman
* Riki is known for being a successful support killer, something Shadow Shaman is very vulnerable to.
* 
Smoke Screen is particularly devastating to Shadow Shaman. With neither his various disables nor a solid health pool Shadow Shaman is usually dead. This forces Shadow Shaman to buy a 
Force Staff if he finds himself in this scenario and buy 
Sentry Wards if you have the money.
Shadow Shaman
* 
Ether Shock is a great farming ability as a handy short-cooldown nuke.
* 
Hex and 
Shackles gives Rubick extra lockdown potential in ganks and teamfights.
* 
Mass Serpent Ward, should Rubick steal, serves as a powerful source for teamfighting, pushing, and acquring Roshan.
* 
Arcane Supremacy allows Rubick to cast Hex and Shackles at a further distance, which keeps Rubick at a safer position compared to Shadow Shaman.
* Rubick can interrupt Shackles by casting 
Telekinesis.
Additional:
* All abilities from Shadow Shaman can very vulnearble steal from 
Spell Steal.
* Rubick can interrupt Shackles by casting Telekinesis.
Shadow Shaman
* As a caster, 
Anti-Mage's 
Mana Break and 
Mana Void are highly effective against him.
Clockwerk
* Anti-Mage can Blink into or out of Power Cogs, negating Clockwerk's initiation and bypassing his defenses.
Additional:
* Anti-Mage can easily 
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.
Shadow Shaman
* Heroes with abilities or items that can silence or disable Anti-Mage for long periods of time will prevent him from Blinking away: Lion, Silencer, Shadow Shaman, 
Grimstroke, 
Witch Doctor, 
Riki, Faceless Void, 
Skywrath Mage, 
Puck.
Shadow Shaman
* Dragon Knight can simply tank and destroy all Shadow Shaman's Serpent Wards.
Shadow Shaman
* Mirana can disturb Shadow Shaman's channeling even if he is under the effect of invisibility thanks to 
Sacred Arrow.
* Mirana armed with an Aghanim's Scepter is known to be able to quickly burst down heroes - especially supports. Together with Ethereal Blade the bullying towards Shadow Shaman can continue for the whole match.
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.
Shadow Shaman
* 
Arc Warden with his Magnetic Field will protect allies from Mass Serpent Ward.
Clockwerk
* Heroes that have a weak laning stage: 
Spectre, Nyx Assassin, Clockwerk, 
Spirit Breaker, Omniknight, 
Pudge.
Shadow Shaman
* Lone Druid's early game is good against slow, squishy supports since his bear is very strong early game and an Entangling Claws proc almost always guarantees a kill: 
Ancient Apparition, 
Crystal Maiden, Shadow Shaman, etc.
Clockwerk
* 
Vengeful Spirit can 
Nether Swap enemies out of Power Cogs.
Additional:
* Nether Swap gives Vengeful Spirit a way to save an ally from Clockwerk's Power Cogs.
* Magic Missile will interrupt Clockwerk trying to run down Vengeful Spirit's allies with Battery Assault.
Shadow Shaman
* Nyx Assassin, Bounty Hunter and Slark can all sneak up and kill Shadow Shaman, Nyx being particularly deadly. Shadow Shaman must watch out for Slark carefully, as he can break either (but not both unless he makes a mistake) of Shadow Shaman's disables, with Dark Pact and leap out of a serpent ward ring. These heroes, however, rely heavily on escape and are themselves not very durable and none of them can survive a full lockdown with Mass Serpent Ward. Having Sentry Wards can turn Shadow Shaman from prey to predator.
Shadow Shaman
* Heroes with summons and illusions can find themselves easily bested by Lina, like Broodmother, 
Nature's Prophet, 
Chen, Terrorblade, 
Naga Siren, Visage, Wraith King, 
Lycan, 
Phantom Lancer, Shadow Shaman.
Clockwerk
* Skywrath Mage's 
Mystic Flare can deal huge damage to Clockwerk inside his Power Cogs.
Shadow Shaman
* Nyx Assassin, Bounty Hunter and Slark can all sneak up and kill Shadow Shaman, Nyx being particularly deadly. Shadow Shaman must watch out for Slark carefully, as he can break either (but not both unless he makes a mistake) of Shadow Shaman's disables, with Dark Pact and leap out of a serpent ward ring. These heroes, however, rely heavily on escape and are themselves not very durable and none of them can survive a full lockdown with Mass Serpent Ward. Having Sentry Wards can turn Shadow Shaman from prey to predator.
Shadow Shaman
* With 4 active abilities, Shadow Shaman is weak against silencing foes such as Silencer, Drow Ranger and Death Prophet.
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
* 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).
Shadow Shaman
* With all 5 Meepos available, all of Shaman's wards will be disposed of very quickly.
* All of Shaman's disables are based around single target control, and he can at most only disable two Meepos, allowing the rest to easily lay waste to him, be it during the channel duration of Shackles or by using 
Earthbind.
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.
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.
Shadow Shaman
* Heroes with channeling spells because Shadow Fiend has nothing to cancel channeling outside of Requiem of Souls: Bane, 
Enigma, Pudge, Shadow Shaman, 
Dawnbreaker, 
Warlock, Crystal Maiden.
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
* 
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.
Shadow Shaman
* Shadow Shaman's Mass Serpent Ward together with Ether Shock can easily kill lots of Treants if played defensively.
* Hex and Shackles can disrupt Nature's Prophet's escape attempts with Teleportation.
Additional:
* Mass Serpent Ward can kill lots of treants if played defensively.
* Mass Serpent Ward, Hex, and Shackles can catch and kill a Nature's Prophet trying to use Teleportation.
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.
Shadow Shaman
* Like above, supports with reliable stuns can be a massive problem and force 
Black King Bar in fights unideally, such as Shadow Shaman, Lion, Nyx Assassin.
Clockwerk
* Power Cogs keeps Primal Beast pinned down, preventing him from doing damage with Trample. Primal Beast's slow attack speed makes it hard for him to break the cogs and get away. In addition, Power Cogs' knockback is forced movement and thus will intercept Primal Beast's Onslaught if placed well.
* 
Battery Assault on a lone Primal Beast in the early game effectively keeps him from winding up Onslaught or basic attacking.
* Rocket Flare and 
Jetpack (from purchasing Aghanim's Shard) give Clockwerk many options to scout for Primal Beast, whose kit benefits greatly from ambushing.
Shadow Shaman
* Heroes who can clear the waves of Enigma's Eidolons: 
Lina, 
Luna, Dawnbreaker, 
Jakiro, Shadow Shaman, Death Prophet, 
Keeper of the Light, Invoker, 
Leshrac, Puck.
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.
Shadow Shaman
* Heroes that are squishy by nature are an easy target for Spirit Breaker: 
Sniper, Drow Ranger, Shadow Shaman
Shadow Shaman
* Can easily interrupt and disable Spirit Breaker with hex if being charged.
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.
Shadow Shaman
* Heroes with break can disable Untouchable for a while: Doom and 
Shadow Demon (via Aghanim's Scepter), 
Viper, Shadow Shaman with Hex Breaks talent.
Clockwerk
* Heroes with nukes that can jump her: Clockwerk, 
Snapfire, Spirit Breaker, 
Techies
Shadow Shaman
* Sven is very vulnerable to chain stun such as Lion, Shadow Shaman or 
Magnus.
Clockwerk
* Heroes who can stun Sven even with an activated Black King Bar can be an issue: Clockwerk, Beastmaster.
Shadow Shaman
* Shackles and Hex can both be used on Muerta while in 
Pierce the Veil, potentially wasting it until she gets Black King Bar.
* Ether Shock and Shackles can deal high damage to Muerta while she is affected by Pierce the Veil.
* However, Mass Serpent Ward cannot hurt Muerta while Pierce the Veil is active.
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.
Shadow Shaman
* Shackles and Mass Serpent Ward instantly destroy 
Refraction
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.
Shadow Shaman
* Hex greatly reduces Timbersaw's mobility.
* The stun and damage over time from Shackles mitigates Reactive Armor's HP and armor regen.
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.
Shadow Shaman
* Shadow Shaman's long disables are effective at kiting and wasting the duration of Battle Trance.
* Mass Serpent Ward are especially effective against Troll Warlord during Battle Trance, as trapping him inside them during the duration is effectively another hard disable, as Troll cannot attack the wards or use Phase Boots to escape.
Shadow Shaman
* Hex's instant cast time will force Brewmaster into the awkward situation of needing some form of spell immunity or block to prevent being immediately hex upon blinking in, or wait until Shaman has used all his crowd control before entering a fight.
* Brewmaster also has no defense against Shadow Shaman lockdowns.
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
* 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.
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
* Battery Assault easily interrupts Centaur Warrunner due to his poor cast animation.
* Power Cogs can negate Stampede.
Shadow Shaman
* Pudge, 
Legion Commander and 
Axe will make the match a living hell for Shadow Shaman, since they are known for surprise attacks from the fog and quickly killing low HP heroes. They can also interrupt Shadow Shaman's channeling, Legion being especially problematic, as she can use 
Press the Attack on an ally who is hexed as well.
Shadow Shaman
* Heroes with long or multiple disables will prevent Legion Commander from winning Duels: Shadow Shaman, Lion
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
* 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).
Clockwerk
* Heroes with long cast animations can be continuously interrupted by Battery Assault: 
Centaur Warrunner, Jakiro, Leshrac, Naga Siren, 
Underlord.
Shadow Shaman
* Heroes with long lockdowns: Shadow Shaman, Legion Commander.
Shadow Shaman
* 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.
Clockwerk
* Heroes with long range abilities are also able to touch Zeus, such as Clockwerk, Kunkka, Puck, Skywrath Mage, Spirit Breaker, 
Tusk and others.
Shadow Shaman
* In general, squishy heroes that rely on escape often struggle against the amount of disables Shadow Shaman can bring. Queen of Pain, Anti-Mage and 
Storm Spirit are among these.
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.
Shadow Shaman
* Heroes with both illusions and summons, for Io has nothing to deal with multiple enemies at once outside from Spirits's weak area-of-effect: Beastmaster, Broodmother, 
Chaos Knight, Lycan, Naga Siren, Nature's Prophet, Phantom Lancer, Shadow Shaman, Terrorblade, Visage, Warlock, Wraith King.
Shadow Shaman
* Heroes with illusions and summons can be hard for Phantom Assassin to deal with, as she lacks any AoE abilities to deal with them without items: Broodmother, Phantom Lancer, Chaos Knight, Lycan, Naga Siren, Shadow Shaman, Visage, Nature's Prophet, Terrorblade, Warlock, Wraith King.
Shadow Shaman
* Viper cannot interrupt heroes with powerful channeling abilities: Bane, Enigma, Shadow Shaman, Warlock
Shadow Shaman
* 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.
Additional:
* Shadow Shaman can provide an excellent counter-initiation against her 
Rebound. His abilities can shut down any of her tower dive attempts in the laning phase.
* Shackles keeps Marci stunned for an extended time, wasting her ultimate. A combo with Mass Serpent Ward only makes things worse for her, as her armor is low.
Shadow Shaman
* Hex abilities can cancel the channelling of Fiend's Grip : Lion, Shadow Shaman, Dazzle from Aghanim's Shard with upgraded Poison Touch.
Clockwerk
* Heroes with long cast animations can be continuously interrupted by Battery Assault: Centaur Warrunner, Jakiro, Leshrac, Naga Siren, Underlord.
Shadow Shaman
* Spectre's entire ability set is designed to get to and destroy heroes that stay in the backlines, both carries (like the aforementioned Drow Ranger and Sniper) and supports (like Dazzle and Shadow Shaman).
Shadow Shaman
* Hex can be used immediately to destroy Spectre's illusion when she 
Haunts.
* Shadow Shaman can use Shackles to lock down Spectre for his team.
* Shadow Shaman's Mass Serpent Ward and Ether Shock help him push lanes and end the game early before Spectre can come online and take over the late game.
Shadow Shaman
* Heroes that have a channeled ability that can be interrupted by Meat Hook: Shadow Shaman, Witch Doctor, Enigma, Bane.
Clockwerk
* 
Meat Hooking a Clockwerk can backfire for Pudge, as Battery Assault and Blade Mail will hurt Pudge more than he hurts Clockwerk.
Shadow Shaman
* With 4 active abilities, Shadow Shaman is weak against silencing foes such as Silencer, Drow Ranger and Death Prophet.
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
* 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.
Shadow Shaman
* Shadow Shaman's many disables can lock down Weaver. Even with Linken's Sphere, Weaver might not be able to escape should Shadow Shaman uses Shackles quickly enough following Hex.
* Mass Serpent Wards can make short work of Weaver once he is locked down.
Shadow Shaman
* Luna's high magical damage burst from 
Lucent Beam and 
Eclipse can take advantage of Shadow Shaman's low health and strength gain.
* Without Black King Bar, Luna's Lucent Beam and 0.25 Eclipse Mini-stun talent for Eclipse can be used to disable Shadow Shaman while he is channeling Shackles.
* Aghanim's Scepter upgraded Eclipse combined with 0.25 Eclipse Mini-stun can repetively stun Shadow Shaman, and can even discourage him from even trying to use Shackles.
* Luna is a natural Black King Bar wielder, and almost none of Shadow Shaman's spells can bypass spell immunity, except for Mass Serpent Ward.
* Bear in mind, however, that if Shadow Shaman gets a jump on Luna first, he will be able to use Hex to disable Luna and burst her down before she can use Black King Bar, Lucent Beam or Eclipse. In addition, 
Moon Glaives cannot bounce on Mass Serpent Wards at all.
Additional:
* Luna's high magical damage burst from Lucent Beam and Eclipse can take advantage of Shadow Shaman's low health and strength gain.
* Without Black King Bar, Luna's Lucent Beam and 0.25 Eclipse Mini-stun talent for Eclipse can be used to disable Shadow Shaman while he is channeling Shackles.
* Aghanim's Scepter upgraded Eclipse combined with 0.25 Eclipse Mini-stun can repetitively stun Shadow Shaman, and can even discourage him from even trying to use Shackles.
* Luna is a natural Black King Bar wielder, and almost none of Shadow Shaman's spells can bypass spell immunity, except for Mass Serpent Ward.
* Bear in mind, however, that if Shadow Shaman gets a jump on Luna first, he will be able to use Hex to disable Luna and burst her down before she can use Black King Bar, Lucent Beam or Eclipse. In addition, Moon Glaives cannot bounce on Mass Serpent Wards at all.
Shadow Shaman
* A couple of nukers and disablers on the same lane can finish a squishy Luna efficiently despite a teammate's assistance: Sven + Shadow Shaman.
Clockwerk
* Every hero that can withstand or prevent Eclipse at level 7: 
Juggernaut, Riki, Clockwerk, Drow Ranger, Abaddon, Faceless Void, Weaver, 
Outworld Destroyer.
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.
Shadow Shaman
* Shackles prevents Chen from acting, and damages him while healing Shadow Shaman, also allowing Shadow Shaman's allies to kill him faster. Aghanim's Shard upgraded Shackles can also summon four more Mass Serpent Wards to attack Chen while he is disabled. And to make things worse, Chen has no way to cancel Shackles on his own, and must rely on outside from {U:Centaur Conqueror} or {U:Mud Golem} under his control.
* Ether Shock and Mass Serpent Ward can often not only kill Chen's allies before he can save them with Hand of God, but they can also be used to destroy Chen's creeps easily thanks to their high damage and area-of-effect.
* Hex will prevent Chen from any attempt to save himself or his allies with Hand of God.

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.
Shadow Shaman
* All of Shadow Shaman's abilities totally ruin Terrorblade: Ether Shock destroys his illusions, Hex prevents him from using Sunder or 
Manta Style in bad situations, Shackles not only that prevent him from using Sunder, but he has no way to cancel it and Mass Serpent Ward can help Shadow Shaman push faster than Terrorblade even in 
Metamorphosis.
Additional:
* Ether Shock, Mass Serpent Wards summoned from both, Mass Serpent Ward and Aghanim's Shard upgraded Shackles can do great damage to both, Terrorblade and his illusions.
* Hex prevents Terrorblade from using Sunder or Manta Style in bad situations. Hex can also destroy one of his illusions.
* Shackles can damage Terrorblade and prevent him from using his abilities and items, whether to fight, survive, or dispel it in any way while also healing Shadow Shaman in process. In addition, Terrorblade has no solutions to cancel it. Aghanim's Shard upgraded Shackles can also summon four more Mass Serpent Wards to attack Terrorblade while he is disabled.
Shadow Shaman
* Sniper can easily destroy Mass Serpent Wards from long range.
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.
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.
Shadow Shaman
* Mass Serpent Ward rips apart Huskar quickly due to his poor armor.
* As soon as Huskar jumps in, he will be vulnerable to Shadow Shaman's disables if he does not have Black King Bar.
Clockwerk
* Blink allows Quen of Pain to easily escape ganking or initiating attempts with Hookshot and Power Cogs.
Shadow Shaman
* Shadow Shaman has many disables to lock down Queen of Pain, preventing her from Blinking away, even through 
Linken's Sphere or her spell block talent.
* Mass Serpent Ward can tear through Queen of Pain's low health pool once she's locked down by Hex & Shackles.
Shadow Shaman
* Heroes with channeling spells are very easy targets for Jakiro's abilities: Crystal Maiden, Dawnbreaker, Enigma, Pudge, 
Shadow Fiend, Shadow Shaman, Warlock.
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
* 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.
Shadow Shaman
* Heroes with silence and mana drain abilites, as Ancient Apparition relies entirely on his abilities: Invoker, Silencer, Nyx Assassin, Skywrath Mage, Shadow Shaman, Lion and etc.
Shadow Shaman
* Pudge, Legion Commander and Axe will make the match a living hell for Shadow Shaman, since they are known for surprise attacks from the fog and quickly killing low HP heroes. They can also interrupt Shadow Shaman's channeling, Legion being especially problematic, as she can use Press the Attack on an ally who is hexed as well.
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
Shadow Shaman
* Due to their high attack speed,
Summon Familiars will destroy Mass Serpent Wards quickly, granting Visage a massive amount of gold.
Stone Form of the Familiars to cancel Shackles. 
Aghanim's Shard upgraded 
Stone Form also allows Visage to use 
Stone Form himself to cancel Shackles while restoring his health.
Grave Chill can make Shadow Shaman's bad movement speed and attack speed even worse.
Bloodthorn wielder, which allows him to silence Shadow Shaman and make him more vulnerable to damage.
