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.
Winter Wyvern
* 
Cold Embrace makes its target immovable, allowing Ancient Apparition to easily land Ice Blast, or a Cold Feet stun.
* Ice Blast also negates healing from Cold Embrace.
Additional:
* Ice Blast disables the healing component of Cold Embrace, making it essentially a 4 second stun on an ally and a perfect setup for Ice Blast.
* If Cold Feet is cast on an Allied hero affected by Cold Embrace, it will almost guarantee the Ally comes out stunned.
Clockwerk
* 
Skywrath Mage's 
Mystic Flare can deal huge damage to Clockwerk inside his Power Cogs.
Winter Wyvern
* Cold Embrace is a perfect setup for Mystic Flare.
* Winter Wyvern is a spellcaster, and the 6 second silence from Ancient Seal can prevent her from contributing much.
* Because Skywrath Mage tends to stay back in fights, Winter Wyvern will have to get close to a teamfight to cast 
Winter's Curse on him. And if she chooses to cast it on one of his allies, his low attack speed and damage means that he won't do much.
* However, bear in mind that Skywrath Mage has seriously awful armor, and that can make him an adequate target to being turned against his own team with Winter's Curse, which can result in his death quickly.
Additional:
* Cold Embrace is the perfect setup for Mystic Flare, and his 6-second silence is good against Winter Wyvern in general.
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.
Winter Wyvern
* Arctic Burn and Splinter Blast's debuffs are can be dispelled with with 
Dark Pact. Arctic Burn also cannot be used to escape against 
Pounce.
* Even though Cold Embrace can protect it's owner from Slark's direct attacks, Slark can still gain 
Essence Shift stacks from attacking heroes affected by it.
* However, Essence Shift works against allies, and Slark's low health pool means that if he's the target for Winter's Curse, he will go down very quickly as Winter's Curse cannot be dispelled at all.
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.
Winter Wyvern
* Even though Ursa is a hero who relies on direct attacks to be effective, 
Fury Swipes does not work on allies if Ursa is affected by Winter's Curse, mitigating a majority of Ursa's damage. In addition, Ursa's unimpressive attack speed and attack damage without 
Overpower and Fury Swipes means that he deals little to no damage to allies during Winter's Curse.
* 
Aghanim's Scepter upgraded Enrage allows Ursa to survive Winter Wyvern's initiation with Winter's Curse.
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
* {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.
Winter Wyvern
* Outworld Destroyer's pure damage from Arcane Orb can go through Cold Embrace.
* Outworld Destroyer can negate the healing from Cold Embrace using Astral Imprisonment, and steal mana while doing so.
* Outworld Destroyer's damage during Winter's Curse is reduced due to Arcane Orb being unable to target allies.
Additional:
* Winter Wyvern must never put her allies in Cold Embrace against Outworld Destroyer as 
Arcane Orb will continue to deal damage to the defenseless hero.
* Arcane Orb does not hit his allies when he is taunted by Winter's Curse, making it weak against allies, but strong versus enemies.
* 
Astral Imprisonment can protect a target inflicted with Winter's Curse.
Winter Wyvern
* Winter Wyvern cannot handle the Zombies created by Undying's Tombstone very well. In most situations, Zombies will have more movement speed than her.
* Undying can gain one or two easy Decay stacks on an ally in Cold Embrace. The ally will still take the damage as well.
Additional:
* Winter Wyvern cannot handle the Zombies created by 
Tombstone very well. In most situations, Zombies will have more movement speed than her.
* Undying can gain one or two easy 
Decay stacks on an ally in Cold Embrace. The ally will still take the damage as well, since it is magical.
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
* 
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 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.
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.
Winter Wyvern
* Cold Embrace is the perfect setup for all his nukes - 
Chaos Meteor, 
E.M.P. and especially global 
Sun Strike.
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.
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
* 
Blink allows Quen of Pain to easily escape ganking or initiating attempts with Hookshot and 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.
Winter Wyvern
* Timbersaw relies on dealing massive amounts of pure damage, making Cold Embrace a good setup for his nukes.
* If he has 
Reactive Armor stacks, Timbersaw can tank the damage from his allies if he is targeted by Winter's Curse. If he's not the target, Timbersaw's abysmal attack damage will contribute next to nothing when he is cursed to attack an ally.
* As Timbersaw commonly buys 
Lotus Orb, he can use it to reflect Winter's Curse back to Winter Wyvern if she uses it impulsively on him or any other hero while affected by it.
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.
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
* Heroes that have a weak laning stage: 
Spectre, 
Nyx Assassin, Clockwerk, 
Spirit Breaker, 
Omniknight, 
Pudge.
Winter Wyvern
* Heroes that depend on disrupting fights with ability combos or big ultimate abilities are vulnerable to the long stun of Fiend's Grip: 
Disruptor, 
Death Prophet, 
Enigma, Faceless Void, 
Invoker, 
Lich, 
Magnus, 
Mars, 
Medusa, 
Outworld Destroyer, 
Phoenix, 
Puck, 
Queen of Pain, 
Shadow Fiend, 
Treant Protector, 
Underlord, 
Winter Wyvern, 
Witch Doctor, 
Zeus.
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.
Winter Wyvern
* Heavy nukers will do well against Cold Embrace (
Lina, Zeus 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.
Winter Wyvern
* Heroes with the ability to heal allies will not be able to heal heroes affected by 
Doom: 
Chen, 
Dazzle, 
Io, 
Oracle, Omniknight, Witch Doctor, Winter Wyvern, Abaddon, 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.
Winter Wyvern
* Many physical-only single-target heroes like Lifestealer, 
Sven, Wraith King, 
Phantom Assassin, 
Templar Assassin can have their damage mitigated by Cold Embrace.
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.
Winter Wyvern
* Heroes with abilities that can save teammates are also effective such as 
Shadow Demon, Dazzle, Oracle, 
Bane, 
Pugna, 
Tusk, Winter Wyvern, Io, Underlord, Treant Protector and 
Keeper of the Light.
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.
Winter Wyvern
* Winter Wyvern's Winter's Curse turns Morphling's high attack damage and attack speed against his targeted teammate.
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.
Winter Wyvern
* Terrorblade and his illusions deal huge damage, which might used against him and his team with Winter's Curse.
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
* 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.
Winter Wyvern
* Broodmother, 
Nature's Prophet, 
Phantom Lancer by their nature offer very good target for Splinter Blast and Winter's Curse.
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.
Winter Wyvern
* Cold Embrace is no salvation against 
Lucent Beam and 
Eclipse.
* 
Moon Glaives will not hit a hero affected by Winter's Curse, making it weak against allies, but strong versus enemies.
* Luna has better night vision provided by 
Lunar Blessing than Winter Wyvern when affected by Arctic Burn.
Additional:
* Cold Embrace is no salvation against Lucent Beam and Eclipse.
* Moon Glaives will not hit a hero affected by Winter's Curse, making it weak against allies, but strong versus enemies.
* Luna has better night vision provided by Lunar Blessing than Winter Wyvern when affected by Arctic Burn.
Clockwerk
* Every hero that can withstand or prevent Eclipse at level 7: 
Juggernaut, 
Riki, Clockwerk, 
Drow Ranger, Abaddon, Faceless Void, Weaver, Outworld Destroyer.
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.
Winter Wyvern
* Winter's Curse, when directly targeted on Enigma, goes through 
Black King Bar, stopping Enigma's Black Hole channeling. It also turns his team against him, potentially killing him. Even if Enigma gets 
Linken's Sphere on top of Black King Bar, 
Splinter Blast can be used to pop Linken's Sphere, and Winter's Curse will stop Black Hole channeling.
* Splinter Blast can be targeted on an eidolon, killing off other eidolons and damaging nearby heroes as well.
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.
Winter Wyvern
* Cold Embrace saves allies from dying in Duels.
* Winter's Curse turns Legion Commander's high damage against her allies, giving the enemy team little time to react.
* However, Winter Wyvern lanes very poorly against Legion Commander due to Press the Attack removing all the debuffs she can give. Winter Wyvern also has little chances of surviving if she gets Dueled herself.
Additional:
* Cold Embrace is very effective against Duel.
* Also, casting Winter's Curse at 
Legion Commander while an ally is in a Duel will stun her for most of the duration, possibly preventing lethal damage dealt to your ally. It can also turn her high-damage against her teammate.
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.
Winter Wyvern
* Broodmother, Nature's Prophet, Phantom Lancer by their nature offer very good target for Splinter Blast and Winter's Curse.
Clockwerk
* Heroes who can stun Sven even with an activated Black King Bar can be an issue: Clockwerk, Beastmaster.
Winter Wyvern
* Cold Embrace saves any ally Sven initiates on and wastes the duration of God's Strength in team fights.
* Winter's Curse can be devastating to Sven's team, as his massive damage can take out a teammate before there is much time to react.
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.
Winter Wyvern
* Supports who can slow him to the point Trample does very little damage in the lane are also not fun: Lich, 
Ogre Magi, Winter Wyvern.
Clockwerk
* Heroes with long cast animations can be continuously interrupted by Battery Assault: 
Centaur Warrunner, 
Jakiro, 
Leshrac, 
Naga Siren, Underlord.
Winter Wyvern
* Winter's Curse and Splinter Blast can devastate Underlord's team when they are grouped up for the teleportation with 
Fiend's Gate.
* Cold Embrace can be used to heal Winter Wyvern's allies, and protect them from the attack damage from 
Atrophy Aura. Bear in mind, however, that the heroes affected by Cold Embrace are easy targets for 
Firestorm and 
Pit of Malice.
Clockwerk
* Battery Assault easily interrupts Centaur Warrunner due to his poor cast animation.
* Power Cogs can negate Stampede.
Winter Wyvern
* Winter Wyvern's 
Arctic Burn can also be a useful tool against Centaur, who generally has very high health. Winter's Curse on Centaur can cause Retaliate to damage allies who are forced to attack him.
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.
Winter Wyvern
* Winter's Curse in late game is pretty much the end for Meepo or any of his nearby allies. Natural counter for Winter's Curse like Linken's Sphere or Lotus Orb is meaningless to her if she can land it on one of Meepo's clones.
Additional:
* Meepo's clones usually gets grouped in teamfight making any of them ideal target for Winter's Curse, forcing Meepo to literally kill himself. Also, unlike other heroes he cannot protect himself with Linken's Sphere.
* While Meepo's clones are grouped up, Splinter Blast will hit almost every clone, slowing Meepo and making him easier to fight.
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
Winter Wyvern
* 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
* 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
* 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.
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.
Winter Wyvern
* Cold Embrace mitigates Primal Roar's single-target initiation on allies.
* Winter's Curse can turn Beastmaster's summons and Inner Beast against his teammate.
Additional:
* Beastmaster's summons and 
Inner Beast are very useful to attack his cursed teammate.
* Cold Embrace effectively mitigates 
Primal Roar's single-target initiation on allies.
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, 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.
Winter Wyvern
* Cold Embrace can protect Troll Warlord's target, especially during Battle Trance.
* Winter's Curse can turn Troll Warlord's high physical damage and attack speed against his allies.
Additional:
* Cold Embrace will protect your ally from being damaged if he gets focused by Troll, although be careful as 
Fervor will keep gaining stacks even while Cold Embrace is active.
* Fervor works on allies.
* His high attack speed will help to kill his cursed ally faster.
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
* 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
* 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.
Winter Wyvern
* Arctic Burn makes it nearly impossible for Spectre to juke into the trees.
* Cold Embrace negates all of Spectre's physical damage. Furthermore, Cold Embrace will generally outheal 
Desolate.
* Winter's Curse can taunt illusions, not only wasting the entire duration of 
Haunt but also turning its illusions against Spectre's own team.
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.
Winter Wyvern
* Cold Embrace can render the extra attack speed from 
Overcharge meaningless.
* Splinter Blast and Winter's Curse are very affective against Io, as it has to stay close to his 
Tethered target.
Winter Wyvern
* Arctic Burn allows Winter Wyvern to escape Lycan, even when he uses his ultimate.
* Splinter Blast is very effective in dealing with Lycan's summons.
* Cold Embrace saves allies from Lycan's raw physical damage and can buy allies enough time to turn the tide of battle.
* Winter's Curse stops Lycan in his tracks and is very effective because of his summons.
Additional:
* All of Lycan's damage is physical which is totally negated by Cold Embrace.
* Lycan often moves around with large amount of creeps, wolves created by 
Summon Wolves and neutral creep dominated by 
Helm of the Dominator which can be easily cleared by Splinter Blast or used as a great source of damage by Winter's Curse. If you catch Lycan with creeps nearby and affected by 
Shapeshift using Winter's Curse on him will most certainly end up with his death.
Winter Wyvern
* Cold Embrace can protect allies from Lone Druid and the Spirit bear, who mainly deal physical damage
* Winter's Curse can turn Lone Druid and the Spirit Bear against his teammates.
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 nukes that can jump her: Clockwerk, 
Snapfire, Spirit Breaker, 
Techies
Winter Wyvern
* Many physical-only single-target heroes like Lifestealer, Sven, Wraith King, Phantom Assassin, Templar Assassin can have their damage mitigated by Cold Embrace.
Clockwerk
* Heroes with long cast animations can be continuously interrupted by Battery Assault: Centaur Warrunner, Jakiro, Leshrac, Naga Siren, Underlord.
Winter Wyvern
* Heroes with other kind of disables that pierce spell immunity can hold Pangolier in place during Rolling Thunder: 
Axe, Beastmaster, Enigma, Magnus, Pudge, Batrider, Bane, Winter Wyvern
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.
Winter Wyvern
* Many physical-only single-target heroes like Lifestealer, Sven, Wraith King, Phantom Assassin, Templar Assassin can have their damage mitigated by Cold Embrace.
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.
Winter Wyvern
* Winter Wyvern's Winter's Curse works very well against the increased attack speed from Bloodlust.
Clockwerk
* Single-target disablers will have difficulty locking down a Chaos Knight with Phantasm active: Bane, Beastmaster, 
Bloodseeker, Clockwerk, 
Doom, 
Shadow Shaman.
Winter Wyvern
* Cold Embrace protects targets affected by Reality Rift.
* Winter's Curse turns Phantasm illusions against Chaos Knight or a teammate.
* Splinter Blast deals decent area damage to Phantasm illusions.
* Arctic Burn's percentage-based damage quickly wears down Chaos Knight's high max health.
Additional:
* Winter Wyvern can make Chaos Knight's illusions attack the real one, provided the player knows who it is.
* Alternatively, Winter's Curse can make Chaos Knight and all his illusions attack one of his allies.
* Cold Embrace protects ally who is focused by Chaos Knight.
* Splinter Blast deals decent area damage to Chaos Knight's illusions.
* Chaos Knight's high health pool and tendency to not build magic resistance items will make Arctic Burn deal a lot of damage to him and his illusions.
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.
Winter Wyvern
* Any hero that can nullify effects of Chronosphere: (Keeper of the Light with Aghanim's Scepter during daytime, Winter Wyvern), banishing him or Faceless Void (Outworld Destroyer, Shadow Demon, 
Earth Spirit with Aghanim's Scepter) or protecting him in other ways (Dazzle, Oracle, Abaddon) can greatly limit Chronosphere's potential.
Winter Wyvern
* 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.
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
* 
Searing Arrows makes Clinkz one of the hardest heroes for Clockwerk to lane against.
Winter Wyvern
* Cold Embrace can heal herself or an ally, as well as protecting them from Clinkz's physical attacks and wasting his mana if Searing Arrows is on autocast.
* Winter's Curse allows Winter Wyvern to turn Clinkz's high damage and high attack speed against his allies, or take advantage of Clinkz's fragility if he can't use Skeleton Walk.
Winter Wyvern
* All of Tinker's damage is magical and pure, which makes Cold Embrace a good setup for his nukes.
* Winter's Curse is very hard to cast on Tinker because he usually stays in the back-lines in team-fights. In turn, Tinker has mediocre attack damage and will contribute very little when he is cursed to attack an ally. He can also save his ally under Winter's Curse effect with Ethereal Blade and 
Defense Matrix.
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).
Winter Wyvern
* Heavy nukers will do well against Cold Embrace (Lina, Zeus etc).
Additional:
* Any ally that Winter Wyvern tries to save with Cold Embrace can still be damaged by all of Zeus's spells.
* If Winter Wyvern tries to juke vision by flying up a cliff or in the trees, Zeus can gain vision there with Lightning Bolt or Thundergod's Wrath.
* If Zeus is forced to attack an ally by Winter's Curse, his unimpressive attack damage and attack speed means they won't be hurt much by him. Zeus will also stay near the back of fights away from his allies, making a deadly Curse less likely.
Clockwerk
* Heroes with long range abilities are also able to touch Zeus, such as Clockwerk, 
Kunkka, Puck, Skywrath Mage, Spirit Breaker, Tusk and others.
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.
Winter Wyvern
* Many physical-only single-target heroes like Lifestealer, Sven, Wraith King, Phantom Assassin, Templar Assassin can have their damage mitigated by Cold Embrace.
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.

Winter Wyvern
* Broodmother, Nature's Prophet, Phantom Lancer by their nature offer very good target for Splinter Blast and Winter's Curse.
Clockwerk
*
Purification does great damage to Clockwerk when fighting an enemy inside Power Cogs.
Purification and 
Heavenly Grace any enemy hero Clockwerk initiates on.
* Due to Clockwerk's very low damage output, Omniknight will have more than enough time to
* For the same reasons, Omniknight also makes a powerful ally for Clockwerk when the situation is reversed.
Winter Wyvern
* Guardian Angel completely counters
Winter's Curse if Omniknight is able to cast it.
Guardian Angel completely counters Winter's Curse, allowing his team to survive Winter Wyvern's initiation.
Purification and 
Repel are very useful against Arctic Burn, Splinter Blast and Winter's Curse as well.
