Undying
* 
Reactive Armor makes Timbersaw very effective against heroes that control a lot of units, such as 
Broodmother, 
Lycan and 
Undying.
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.
Undying
* 
Invoker's multiple spells can lock down Undying and disable him from doing much.
Winter Wyvern
* Cold Embrace is the perfect setup for all his nukes - 
Chaos Meteor, 
E.M.P. and especially global 
Sun Strike.
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.
Winter Wyvern
* Guardian Angel completely counters 
Winter's Curse if Omniknight is able to cast it.
Additional:
* 
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.
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.
Undying
* Split Shot can destroy Tombstone Zombies and Tombstone itself while still damaging heroes.
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.
Undying
* Zombies summoned from Tombstone will amplify the damage of 
Echo Slam due to them increasing the echo damage.
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.
Undying
* Chemical Rage will take down 
Tombstone in no time.
Additional:
* With 
Greevil's Greed, Alchemist can farm Tombstone zombies and gain a significant gold advantage.
Undying
* Geminate Attack works on Tombstone, allowing Weaver to kill it quickly.
* Zombies attacking Weaver disappear once he goes invisible with Shukuchi.
* Undying has no way to catch a mobile Weaver.
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.
Undying
* Tidehunter takes close to no damage from Undying's zombies once he maxes out his 
Kraken Shell, especially if he gets the level 20 Kraken Shell upgrading talent. This might allow him to blink away to safety.
Undying
* 
Arcane Curse can effectively discourage Undying from casting his spammable abilities in a team fight, as Undying will have to suffer more damage and the slow due to the penalty duration of Arcane Curse.
* 
Last Word and 
Global Silence are able to silence Undying for up to 6 seconds, preventing Undying from gaining strength and healing his ally or himself.
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.
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.
Undying
* Necrophos is a dangerous opponent to go against with. Regardless of how much strength Undying has gained from Decay, Necrophos can finish off Undying with 
Reaper's Scythe once Undying's HP falls below a certain threshold.
* 
Heartstopper Aura will do more damage to Undying if he gained strength from Decay, as it does damage based on a hero's maximum health.
Undying
* Tombstone can be stolen to counter-initiate the enemy team in skirmishes.
* Tombstone provides vision over the enemy around, use this to Rubick's advantage for more spells.
* Since Undying is melee and has low attack speed, the tombstone can be hard to taken down by Undying himself.
* 
Flesh Golem provides Rubick with increased Health pool and a powerful attack modifier.
* 
Rubick can apply the Flesh Golem debuff much more easily as a ranged hero.
* 
Decay is a decent damaging ability, making Rubick somewhat tankier in teamfights.
* 
Soul Rip can be used for extra heal or burst damage.
Additional:
* All abilities from Undying easy to steal to Rubick with 
Spell Steal.
Undying
* Tombstone's zombies rarely inhibit Anti-Mage, as he can either Blink away or onto the Tombstone and destroy it.
Undying
* Sniper can easily destroy Tombstone from long range.
Undying
* Flak Cannon rips through Tombstone's zombies.
Additional:
* 
Flak Cannon enables Gyrocopter to clear the zombies easily.
Undying
* Familiars will easily be able to kite heroes with a short range or with low attack speed. For example, 
Tiny and Undying have a very hard time killing Familiars.
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.
Winter Wyvern
* Heavy nukers will do well against Cold Embrace (
Lina, Zeus etc).
Undying
* Death Prophet is able to 
Silence Undying up to 6 seconds. Besides, due to Undying's high strength during a team fight, 
Spirit Siphon is a powerful ability against Undying thanks to the percentage health drain.
Undying
* 
Huskar's huge damage output and attack speed can get rid of Undying and Tombstone quickly.
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.
Undying
* 
Mirana can destroy Tombstone, and evade zombies using Leap and Moonlight Shadow's invisibility.
Undying
* Heroes with summons that are destroyed by a fixed number of attacks: Undying's Tombstone, 
Gyrocopter's 
Homing Missile, and Zeus's 
Nimbus.
Undying
* Lifestealer is able to endure Undying, especially in the laning phase, where Undying is strongest. Feast can offset Decay's strength steal for its percentage lifesteal. Rage delays Undying from stealing strength and can help Lifestealer destroy Undying's Tombstone uninterrupted. As well, none of Undying's abilities pierce magic immunity.
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.
Undying
* Phantom Lancer's many illusions will easily destroy Tombstone, provided he has sufficient farm.
* He also has no ways of dealing with the illusions, since Decay doesn't steal strength from illusions.
Winter Wyvern
* Broodmother, 
Nature's Prophet, 
Phantom Lancer by their nature offer very good target for Splinter Blast and Winter's Curse.
Undying
* Spectre must chase for kills and relies on movement speed for mobility in fights, and has no way to counter the Tombstone zombies.
* The potency of Soul Rip can be increased from nearby illusions from Haunt.
* Decay will shut down Spectre during the laning phase by effectively cutting down her initial health pool.
Additional:
* Spectre must chase for kills and relies on movement speed for mobility in fights, and has no way to counter the Tombstone zombies.
* The potency of Soul Rip can be increased from nearby illusions, so Undying can use 
Haunt against Spectre.
* Early game Decay will make Spectre easy to shut down in lane.
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.
Undying
* Undying can use Decay not only to reduce Sven's maximum health, but also to reduce the damage he can deal with his ultimate.
* Zombies spawned by Tombstone together with Flesh Golem slow Sven down significantly. Landing Sven's powerful but somewhat slow right-click on Tombstone would be a waste.
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.
Undying
* Undying's Tombstone will cheerfully chew through treants, incidentally netting you some extra income during fights.
* The above interaction tends to ensure that skirmishes are heavily populated with units, thereby buffing Soul Rip
Winter Wyvern
* Broodmother, Nature's Prophet, Phantom Lancer by their nature offer very good target for Splinter Blast and Winter's Curse.
Undying
* Undying saps strength from heroes with Decay, and Ogre Magi's high strength gain will allow Undying to steal more and more strength, becoming stronger with each use.
* Due to the Strength steal from Decay, Undying is normally very tanky, and has high health, making it harder for Ogre Magi to kill him.
Winter Wyvern
* Winter Wyvern's Winter's Curse works very well against the increased attack speed from Bloodlust.
Undying
* Decay can be good against Centaur Warrunner, as reducing the health of Centaur can make 
Double Edge risky.
* His zombies do not proc 
Retaliate, as it only procs for regular attacks.
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.
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.
Undying
* Undying's Decay is a dangerous ability against Bristleback, as it makes him more vulnerable and reduces his tankiness.
* Undying's Tombstone together with Flesh Golem can slow Bristleback down significantly.
Undying
* Decay, Soul Rip and Flesh Golem all deal magical damage which ignores Bulwark.
* Decay reduces Mars' natural strength and therefore his health pool, which is what he relies on to trade effectively in lane.
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.
Undying
* Due to Spirit Breaker's low attack speed, Tombstone is problematic for Spirit Breaker as the zombies summoned from Tombstone apply a stacking movement speed slow, which can significantly reduce Greater Bash's damage.
* Soul Rip and Decay allows Undying and his allies to survive and recover from any incoming ganks by Spirit Breaker.
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
* 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
* 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.
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.
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.
Winter Wyvern
* Winter Wyvern's Winter's Curse turns Morphling's high attack damage and attack speed against his targeted teammate.
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
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.
Undying
* Generally, any fragile heroes will have a hard time dealing with Undying's tankiness, and even more so if Decay is used on them. Some examples are 
Crystal Maiden and Witch Doctor.
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
* 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.
Undying
* Anti-Tank heroes like: 
Razor, 
Necrophos, Undying.
Undying
* Generally, any fragile heroes will have a hard time dealing with Undying's tankiness, and even more so if Decay is used on them. Some examples are Crystal Maiden and Witch Doctor.
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.
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.
Winter Wyvern
* Broodmother, Nature's Prophet, Phantom Lancer by their nature offer very good target for Splinter Blast and Winter's Curse.
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.
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
Undying
* 
Chaos Knight's multiple illusions from 
Phantasm can destroy Undying, as Soul Rip can't offset the damage from the high amount of damage from his illusions.
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.
Undying
* 
Meepo can quickly destroy Tombstone thanks to 
Divided We Stand.
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.
Undying
* Heroes without blink mechanisms or spell immunity will have a hard time positioning against 
Pit of Malice: Sven, Tiny, Wraith King, 
Dragon Knight, Meepo, 
Doom, 
Bounty Hunter, 
Dark Seer, Undying, 
Alchemist, Legion Commander.
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.
Undying
* 
Terrorblade can destroy Tombstone with his 
Conjure Image and 
Metamorphosis.
Winter Wyvern
* Terrorblade and his illusions deal huge damage, which might used against him and his team with Winter's Curse.
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.
Undying
* Heroes with a slow attack rate will find themselves struggling to take out Tombstone, like Doom.
Undying
* Due to Fervor and Battle Trance, Troll Warlord has a significant attack speed, enabling him to crush Tombstone quickly.
* Undying usually stays at the front line with no disables, making him an easy target for Troll Warlord.
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.
Undying
* Luna's
Moon Glaives and 
Lunar Blessing can help her destroy Tombstone easily, and this becomes more effective if Luna is equipped with 
Manta Style.
Eclipse will strike only Undying, which can turn Undying's own ability against him.
Blade Mail which can turn Luna's burst damage against her, Luna often builds 
Black King Bar which will allow her to attack Undying freely because 
Blade Mail cannot pierce spell immunity.

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.
Lunar Blessing than Winter Wyvern when affected by Arctic Burn.
Lucent Beam and
