* Winter's Curse, when directly targeted on Enigma, can go through Avatar, stopping Enigma's Black Hole channeling. It can also can turn his team against him, potentially killing him.
* Splinter Blast can be targeted on an eidolon, killing off other eidolons and damaging nearby heroes as well.

* Chaotic Offering's spell immunity piercing stun can stop Black Hole's channeling. Due to this ability's large area of effect, it can be cast at a safe distance from the Black Hole.
* Fatal Bonds can be used to make Enigma's Eidolons easier to kill, potentially feeding the enemy team.
* Warlock's Upheaval can interfere with Enigma's initiation and potential follow-ups thanks to its large AoE.
Additional:
* Chaotic Offering pierces spell immunity and is an area of effect ability, therefore it doesn't matter if Enigma buys Black King Bar or Linken's Sphere Warlock will always be able to cancel channeling of Black Hole.
* Enemies often get clumped up around Black Hole giving Warlock a perfect opportunity to cast Fatal Bonds and Upheaval on multiple enemies.

* 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 your 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 another hero 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.

* Fatal Bonds links the Meepos together.

* 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.

* {U:Warlock Golem}s do plenty of physical and pure damage to bring down Huskar when he is at low health. Warlock is always a hazard for Huskar to initiate by using Life Break because Chaotic Offering can stun him instantly, even when Black King Bar is activated, and allow Warlock's team to gather their wit and retaliate.
* After jumping in, Huskar will not have any means to escape Upheaval. Being an attack-dependent hero, this is bad for him.

* 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 its tethered hero.

* Many physical-only single-target heroes like Lifestealer, Sven, Wraith King, Phantom Assassin, Templar Assassin etc.

* Warlock can cast Upheaval when Templar Assassin uses Meld, preventing escape.
* Warlock can also send his {U:Warlock Golem} near where she used Meld, preventing escape by Blink Dagger due to the {U:Warlock Golem} Permanent Immolation.

* Winter's Curse and Splinter Blast can devastate Underlord's team when they're grouped up for Dark Rift.

* Cold Embrace can protect Troll Warlord's target, especially during Battle Trance.

* His high attack speed and bash will help to kill his cursed ally faster.

* 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.

* 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.

* Lacking escaping mechanisms, being dependent on fair positioning and channeling for his ultimate, its easier to Warlock with your long range crowd control abilities to lock the Shadow Fiend down to your team.

* Chaotic Offering's vast area-effect can destroy trees and stun Hoodwink.
* Upheaval makes retreating with Scurry difficult.

* 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.

* Cold Embrace mitigates Primal Roar's single-target initiation on allies.

* Heroes who can slow and kite Axe will severely inhibit his presence in fights: Bristleback, Crystal Maiden, Batrider, Arc Warden, Winter Wyvern, Clockwerk

* Broodmother, Nature's Prophet, Phantom Lancer by their nature offer very good target for Splinter Blast and Winter's Curse.

* 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.

* Terrorblade and his illusions deal huge damage, which might used against him and his team with Winter's Curse.

* Channeling heroes will not go well against Warlock, especially those who build Black King Bar as Warlock's ultimate ability stun goes through spell immunity. E.g.: Crystal Maiden, Shadow Fiend, Enigma, etc.

* While heroes with strong mobility able to get close/flee or long range disables do well against him, heroes with no escaping abilities/lacking long disables will perish against Warlock. Once the {U:Warlock Golem} lands with its stun, its hardly possible to escape when he casts Upheaval. Just watch your pet burn the enemies as they try running away or blow their strongest abilities to stop your {U:Warlock Golem}. Notable examples: Huskar, Drow Ranger, Lion, Elder Titan, etc.

* Warlock often stays back and counter-initiates by dropping his Chaotic Offering on Earthshaker and his allies.

* Winter Wyvern's Winter's Curse turns Morphling's high attack damage and attack speed against his targeted teammate.

* While heroes with strong mobility able to get close/flee or long range disables do well against him, heroes with no escaping abilities/lacking long disables will perish against Warlock. Once the {U:Warlock Golem} lands with its stun, its hardly possible to escape when he casts Upheaval. Just watch your pet burn the enemies as they try running away or blow their strongest abilities to stop your {U:Warlock Golem}. Notable examples: Huskar, Drow Ranger, Lion, Elder Titan, etc.

* Winter Wyvern's Winter's Curse works very well against the increased attack speed from Bloodlust.

* Ursa's extremely high attack damage output with Fury Swipes usually means certain death for anyone cursed in his vicinity.

* 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.

* Cold Embrace protects targets of Reality Rift.
* Winter's Curse turns Phantasm illusions against Chaos Knight or a teammate.
* Splinter Blast deals decent area damage to Phantasm illusions.

* 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.

* 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.

* 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.

* Heroes with the ability to heal allies, or those with good defensive abilities: Chen, Dazzle, Io, Oracle, Omniknight, Witch Doctor, Winter Wyvern, Abaddon, etc.
