* Burning Spear's magical damage is very troublesome for Mars in the laning stage.
* Life Break's percentage-based magical damage bypasses Bulwark, and can also be used to jump in or out of Arena Of Blood.

* Berserker's Call forces Mars to face in the direction choosen.
* Counter Helix is a much stronger lane trader than Spear of Mars.

* Heroes that have AoE damage: Lina, Keeper of the Light, Timbersaw, Leshrac, Bristleback, Axe

Additional:
* Berserker's Call and Counter Helix will still hit targets inside of a defensive Sprout.
* Counter Helix clears treants in no time.
* Nature's Prophet's low damage is unlikely to hurt Axe until the very late game.
* Nature's Prophet's low mobility makes him very easy for Axe to chase down or initiate on, especially when affected by Battle Hunger.

* Sprout will not protect Nature's Prophet from Huskar if he has already locked on with Life Break.
* Even a farmed Nature's Prophet is usually not durable enough to fight Huskar alone.

* Heroes with damage over time abilities can quickly eat through Gravekeeper's Cloak charges like Huskar, Jakiro and Queen of Pain.

* Axe can Berserker's Call into a flock of Familiars, procing Counter Helix and killing them off.
* Familiars' very fast attacks will proc Counter Helix, receiving full damage due to their low attack range.

* Weaver cannot Time Lapse out of Huskar's burn damage.

* Berserker's Call is one of the best ways to lock down Weaver before he has a chance to use Time Lapse. It can also catch Weaver in Shukuchi.
* Weaver's high attack speed, along with high attack damage from Geminate Attack, triggers Counter Helix continuously and the output damage would be returned by Blade Mail.
Additional:
* Berserker's Call is one of the best ways to lock down Weaver before he has a chance to use Time Lapse. It can also catch Weaver in Shukuchi.
* Due to his fast attack speed from Geminate Attack and items that give attack speed, Counter Helix will activate a lot, and the damage would be returned by Blade Mail, which hurts Weaver far more than it hurts Axe.
* Culling Blade can finish off Weaver's low health pool before he escapes with Shukuchi and Time Lapse.
* Battle Hunger is a good tool to pop Weaver's Linken's Sphere due to its low cooldown.

* Berserker's Call forces Drow Ranger to attack Axe up close, disabling her Marksmanship bonus.
* Counter Helix occurs more often with Drow Ranger's high attack speed.
* Culling Blade is a dangerous ability against a low health hero like Drow Ranger.

* Life Break closes the distance between Huskar and Drow Ranger, dealing large amounts of damage and disabling Marksmanship.
* Berserker's Blood and Burning Spear allow Huskar to beat Drow Ranger directly and pile on damage.

* Heroes that can keep Monkey King stunned for a long time can pose a threat: Axe, Centaur Warrunner.

* Burning Spears can put Monkey King's Tree Dance on cooldown.

Additional:
* Inner Fire can push Monkey King out of Wukong's Command.
* Burning Spear's damage over time will constantly put Tree Dance on cooldown.

* 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

* Certain heroes can mess up with Pangolier's positioning and timing (especially if he intends to use Rolling Thunder during combat): Vengeful Spirit, Keeper of the Light, Huskar, Dark Seer

* Berserker's Blood can potentially out-heal the damage over time from Ink Swell and Phantom's Embrace.
* Life Break can break Soul Bind if used correctly.

* Ember Spirit does minimal damage to Huskar until the very late game.

* Since Tidebringer has a 4 second cooldown, Kunkka has little availability to manfight Huskar.

* Jumping on Axe from Waveform he will be an easy target for a counter-initiation with Berserker's Call.
* Morphling is often played at low health to maximize the bonuses from Attribute Shift (Agility Gain), and also because his abilities cost health to use. This makes him especially vulnerable to Culling Blade.
* However, Morphling is common Linken's Sphere carrier to block Culling Blade forces Axe to use Battle Hunger to pop the Spell Block first.
* Attribute Shift (Agility Gain) gives Morphlig no protection against the pure damage of Culling Blade. Its attack speed bonus also means that Counter Helix will proc more often.

* Berseker's Call catches Slark in Shadow Dance, wasting its duration and preventing him from escaping to regenerate.
* Unlike most disables, Dark Pact cannot dispel Berserker's Call, and the output damage would be returned by Blade Mail.
Additional:
* Berserker's Call forces Slark to attack him, even during Shadow Dance.
* Counter Helix will hit Slark in Shadow Dance, with pure damage. It also triggers frequently against Slark's high attack speed after having stolen agility with Essence Shift.
* Culling Blade finishes off Slark before he gets a chance to slip away and regenerate his health, preventing him from playing the hit-and-run style often associated with Slark.

* Berserker's Call and Counter Helix allow Axe to kill Shadow Fiend if he stands too close to a creep wave.
* Battle Hunger is very strong against Shadow Fiend in the early game because Shadow Fiend's low attack damage makes it hard for him to get last hits.
* Axe's naturally high strength and health regeneration will be enough to tank a lot of Shadow Fiend's damage in the early game.

* Magnus cannot manfight Huskar even with Empower, Berserker's Blood's high attack speed and health regeneration, combined with Huskar's high health and Burning Spear stacks will allow Huskar to kill Magnus before he can kill him.
* From a safe distance, Huskar can surprise and counter Magnus's initiation with Life Break and Burning Spear.
* Burning Spear also deals damage over time, disabling Blink Dagger and preventing him from initiating or escaping.

* Huskar's burn damage from Burning Spear is incredibly strong against Templar Assassin as it completely cancels out her Refraction from the burning over time which results in making her very vulnerable to being ganked or harassed, and in turn forcing her out of the lane.

* Earthshaker's stuns will rarely save him once Huskar has initiated on him with Life Break.
* A full initiation combo will not kill Huskar, only lower his health and increase his attack speed.

* Life Break along with Burning Spear can quickly kill Razor before Static Link steals enough damage for Razor to take down Huskar.
* Berserker's Blood can make stealing Huskar's damage and using it against him somewhat dangerous, as Huskar will be able to inflict more and more Burning Spears rapidly.

* False Promise will not save an ally from Culling Blade if their health is low enough.
* Fate's Edict, offensively or defensively, does little to protect Oracle's allies from the majority of Axe's damage.

* Berserker's Call forces Dark Willow to attack, cancelling Shadow Realm.

* Huskar's natural reliance on health instead of mana makes him very resistant against Mana Void. He is a proficient early ganker against Anti-Mage, but struggles to deal significant damage against Anti-Mage in the late game.

* Berserker's Call prevents Anti-Mage from escaping with Blink, and works well with Blade Mail against Anti-Mage's relatively low health.
* Counter Helix deals pure damage, ignoring the protection from Counterspell.
* Counter Helix will trigger even if Axe's depleted of mana, which will make Anti-Mage take more damage than he's dealing.
* Axe's low mana pool makes him a bad target for using Mana Void.
* Axe's high base health regeneration allows him to dominate the lane against Anti-Mage, especially with a support.
Additional:
* Berserker's Call is one of the most reliable ways to lock down Anti-Mage, preventing him from Blinking away.
* Anti-Mage's high attack speed, along with illusions from Manta Style, triggers Counter Helix continuously.
* Axe's low mana pool and high health pool makes Mana Void deal very little damage to Axe.

* Axe can disable Cloak and Dagger's invisibility with Berserker's Call, which forces Riki to attack him at a very bad angle.
* Axe has a very high HP pool, making it hard for you to kill him before you get big items - that is if you survive engaging him. Counter Helix ignores your armor and goes straight for your tiny HP pool, totally ignoring Smoke Screen.

* Berserker's Call can catch Broodmother in her web, as well as groups of spiderlings. This is particularly effective when Broodmother attempts to push towers with her spiderlings.
* Counter Helix destroys spiderlings very quickly, and earns Axe a good deal of gold.
Additional:
* Berserker's Call forces Broodmother and her spiderlings to attack, allowing for large amounts of pure damage to be done through Counter Helix.

* Vulnerable spellcasters with no escape mechanisms are easy targets for Huskar: Lich, Crystal Maiden, Silencer, Keeper of the Light, Venomancer, etc.

* Heroes that are hard to gank: Axe, Death Prophet, Phantom Lancer

* Bristleback, Centaur Warrunner, Spirit Breaker, Pudge, Huskar: These heroes are too tanky for Puck to burst down. Also, all of them have spells which can deal with and shut Puck down reliably.

* Melee heroes who rely on summons, illusions or clones will trigger Counter Helix more often, thus taking more damage: Meepo, Lycan, Chaos Knight, Phantom Lancer

Additional:
* The combination of Counter Helix and Berserker's Call can disable multiple Meepos and deal heavy area damage.
* Axe's natural high survivability makes it difficult to burst him down with Poof or chip away at his health with Ransack.

* Huskar can burn down Dragon Knight's health quickly during the early to mid game, but is not as effective during the late game. However, Life Break remains a constant threat due to the slow and percentage-based damage.

Additional:
* Huskar can negate Dragon Knight's passive with multiple trades of Burning Spear.

* Durable heroes can fight with stand against Tusk during 1v1: Axe, Dragon Knight, Night Stalker, Centaur Warrunner, Wraith King and more.

* Techies struggles early game against heroes with naturally large strength and health regeneration such as Pudge, Axe or Ogre Magi, as the player is forced to lay down more mines than usual to kill these bulkier heroes.

* Vulnerable spellcasters with no escape mechanisms are easy targets for Huskar: Lich, Crystal Maiden, Silencer, Keeper of the Light, Venomancer, etc.

Additional:
* Lich is going to have a hard time nuking Huskar because of his high health regeneration from Berserker's Blood.
* Lich is a squishy support without an escape mechanism, making Lich an easy kill thanks to Life Break and Burning Spear.
* Once Huskar has Armlet of Mordiggian, even a maxed out Frost Blast will struggle to finish Huskar off.

* Heroes with burst damage of their own won't be afraid to go toe to toe with Void Spirit, like Ursa, Lifestealer, or Axe.

* Huskar with Life Break
* Heroes that can remove the Track debuff with their skills:
* Abaddon with Aphotic Shield and Borrowed Time
* Huskar with Life Break
* Juggernaut with Blade Fury
* Legion Commander with Press the Attack
* Lifestealer with Rage and Infest
* Naga Siren with Mirror Image
* Omniknight with Heavenly Grace
* Oracle with Fortune's End and False Promise
* Phantom Lancer with Doppelganger
* Slark with Dark Pact
* Ursa with Enrage
* Weaver with Time Lapse
* Tidehunter with Kraken Shell when damage received reaches the threshold.

* Life Break and Burning Spear usually kills Gyrocopter before he can do much damage to Huskar.
* Inner Fire applies a disarm on all enemies, which can be a hindrance to Gyrocopter.

* Axe can easily close the distance to Sniper with either Blink Dagger or Shadow Blade.
* With Berserker's Call in combination with Counter Helix and Battle Hunger, Axe can make short work of Sniper, finishing him off easily with Culling Blade due to his low HP & high attack speed in the late game.

* Terrorblade's low base health and lack of mobility make him an easy target for Axe to initiate on, and kill.
* Counter Helix will trigger from, and destroy many of Terrorblade illusions.
Additional:
* Berserker's Call and Counter Helix together can be devastating to Terrorblade, especially if Terrorblade has a lot of illusions. Their high attack speed will trigger Counter Helix a lot, and the pure damage will quickly slice through Terrorblade's low health and kill his illusions.
* Culling Blade finishes off Terrorblade before he has the chance to Sunder due to his low health in the early to mid game.

* Berserker's Call helps locks down Phantom Lancer in a group of illusions.
* Counter Helix clears Phantom Lancer's illusions quickly.
* Blade Mail Phantom Lancer's high damage is bad against Blade Mail, an item Axe almost always gets.
Additional:
* Berserker's Call catches Phantom Lancer when he is hidden among his illusions.
* Counter Helix quickly destroys Phantom Lancer's illusion army. The more illusions there are, the more often Counter Helix is triggered.
* Phantom Lancer's low early game health makes him an easy target for Culling Blade.

* Culling Blade ignores the protection from Shallow Grave, and will kill any target whose health is low enough. This makes Axe one of the hardest counters to Dazzle, and he neutralizes one of Dazzle's most important abilities.
Additional:
* Culling Blade kills any target under the health threshold, even through Shallow Grave.

* Phantom Strike's extra attack speed causes Phantom Assassin to proc Counter Helix more often. Using it on Axe also makes Phantom Assassin an easy target for a counter-initiation with Berserker's Call and Blade Mail.
* Most of Axe's abilities pierce Black King Bar, allowing him to lock down Phantom Assassin at any time.
* Berserker's Call greatly reduces Phantom Assassin's ability to crit hard against Axe, and may cause her to kill herself when used with Blade Mail.
Additional:
* Jumping in with Phantom Strike makes Phantom Assassin an exceptionally easy target for Berserker's Call.
* The bonus attack speed from Phantom Strike also means that Phantom Assassin will proc Counter Helix numerous times.
* Black King Bar is generally useless against Axe's abilities and item build, as Black King Bar doesn't prevent Axe from finishing Phantom Assassin off with Culling Blade. It also doesn't work against Berserker's Call and Counter Helix.
* Blade Mail is an item that Axe purchases every game, and it can be used to turn Phantom Assassin's critical strikes against herself. The situation becomes even worse if she's affected by Berserker's Call, as she has no way to stop attacking.

* Troll Warlord has significant attack speed due to Fervor and Battle Trance, giving Axe a higher chance to proc Counter Helix and seriously injure Troll Warlord due to his relatively low maximum health.
* Axe often purchases Blade Mail, which can help Axe turn Troll Warlord's farm and high physical damage against him. The bonus armor provided by Berserker's Call means that Troll Warlord will take a lot more damage than Axe.
* Culling Blade is still capable of killing Troll Warlord during Battle Trance if his HP is low enough.
Additional:
* Troll Warlord's high attack speed means Counter Helix will proc extremely frequently even without creeps near him. This, combined with a Blade Mail means Axe can easily solo kill Troll Warlord even in later stages of the game.

* Huskar's high attack speed can counteract Fire Spirits, and easily destroy the Supernova.
Additional:
* Berserker's Blood will let Huskar easily face down a Supernova with increased attack speed.
* Icarus Dive may not be an easy escape from Huskar either as he can chase Phoenix during it with Life Break if Huskar times it right.

* Berserker's Call and Counter Helix makes short work of Chaos Knight's Phantasms.
Additional:
* Berserker's Call allows Axe to lock down Chaos Knight and his illusions.
* Counter Helix combined with Blade Mail clears illusions out in no time.

* Berserker's Blood works proportionate to lost health, but Huskar has a decent health pool, and the attack speed granted from Berserker's Blood powers him up.
* Skywrath's armor and agility gain is very low so Huskar can outdamage him or take Skywrath down with him.

* 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.

* Vulnerable spellcasters with no escape mechanisms are easy targets for Huskar: Lich, Crystal Maiden, Silencer, Keeper of the Light, Venomancer, etc.

* Axe will destroy her illusions by proccing Counter Helix more often due to him being hit by more attacks.

* Culling Blade's instant kill is not prevented by Borrowed Time should Abaddon's health falls below the threshold.

* Windrun does not provide protection against Counter Helix and Berserker's Call. Her fast attack speed with Focus Fire will also quickly trigger Counter Helix multiple times.

* Heroes who continue dealing damage while being stunned: Luna, Razor, Axe, Bristleback, Leshrac,

* Melee heroes who rely on summons, illusions or clones will trigger Counter Helix more often, thus taking more damage: Meepo, Lycan, Chaos Knight, Phantom Lancer

Additional:
* Berserker's Call can keep Lycan in place during his Shapeshift even through Black King Bar.
* Counter Helix is very effective against Lycan because of his summons.
* Culling Blade will prevent Lycan from running away with Shapeshift when he drops low.

* Heroes with gap closing abilities will be easy targets for Berserker's Call: Phantom Assassin, Faceless Void, Slark, Chaos Knight, Morphling, Queen of Pain

* Vulnerable spellcasters with no escape mechanisms are easy targets for Huskar: Lich, Crystal Maiden, Silencer, Keeper of the Light, Venomancer, etc.

* Berserker's Call pierces spell immunity, making a Blade Fury teleport escape impossible. It's very useful against Omnislash as well.
* Juggernaut's low base health and high attack speed causes him to take a lot of damage from the pure damage of Counter Helix.
* Axe is a common Blade Mail and Blink Dagger carrier making him a very big potential threat before Juggernaut gets items.
