* Quas Exort Invoker has high physical damage in the form of Cold Snap and Forged Spirits that allows him to trade hits with Huskar.
* Although Huskar can dispel Cold Snap with Life Break.
* Sun Strike deals pure damage and pierces spell immunity, and Huskar tends to drain his HP, making him a susceptible target.

* Berserker's Call and Blade Mail can be used immediately after Huskar jumps on Axe with Life Break.
* Huskar's high attack speed procs Counter Helix repeatedly.
* Huskar's health loss from using his abilities make him a frequent target for Culling Blade.
Additional:
* Huskar is often played at low health to maximize the bonuses from Berserker's Blood, and also because his abilities cost health to use. This makes him especially vulnerable to Culling Blade.
* Berserker's Blood gives Huskar no protection against the pure damage of Culling Blade. Its attack speed bonus also means that Counter Helix will proc more often.
* Axe's tankiness and base health regeneration makes it hard for Huskar to take him down with Burning Spears.

* Heroes with long animations can be frequently interrupted with Cold Snap: Earthshaker, Monkey King, Shadow Fiend Lina

* 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.

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

* Heroes with high magical or pure damage will bypass Bulwark: Timbersaw, Dark Willow, Enigma, Invoker, Pugna, Skywrath Mage, Tinker, Zeus, Oracle.

* 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.

* Some heroes with extreme range, like Zeus, Invoker or Clockwerk, can snipe your allies from anywhere after your Grave has expired.

* Heroes that can stall pushes: Invoker, Keeper of the Light, Lina, Luna.

* 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.

* Cold Snap allows Invoker to interrupt Charge of Darkness and Nether Strike.
* Tornado's long range can be used to cancel Charge of Darkness.
* Deafening Blast prevents Spirit Breaker from right clicking and thus proccing his Greater Bash.

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

* Invoker's arsenal of magical spells are troublesome for Sniper who has low HP and high armor, which does not benefit him much against Invoker.
* Besides magical damage, he can be disarmed and repeatedly mini-stunned with Cold Snap, preventing him from reacting.
* Leveling Quas can allow Invoker to lane effectively against Sniper despite right-click harassment.

* 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.

* 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.

* Heroes with powerful area-of-effect disables can initiate on Meepo and his clones and shut him down, such as Enigma, Invoker, Magnus, Puck, and Sand King.

* 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.

* Heroes with summons like Broodmother,Enigma, Invoker, Nature's Prophet, Lycan, Visage;or illusions, like Naga Siren, Phantom Lancer, Terrorblade are effective at keeping the choke points and rune spawns safe from Proximity mines in the early game.

* Heroes with long animations can be frequently interrupted with Cold Snap: Earthshaker, Monkey King, Shadow Fiend Lina

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

* 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.

* 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 helps locks down Phantom Lancer in a group of illusions.
* Counter Helix combined with Blade Mail clears Phantom Lancer's illusions quickly.
* Phantom Lancer's low health in the early game makes him a frequent target for Culling Blade.
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.

* 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 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 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.

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

* 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.

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

* 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.
* Battle Trance does not save Troll Warlord from a Culling Blade.

* Invoker can drain Wraith King's mana with EMP, preventing him from reincarnating unless Wraith King has his Aghanim's Shard.
* Even if Wraith King survives and reincarnates, Invoker still has an arsenal of spells to lockdown Wraith King, including an easily setup Ice Wall.
* Tornado applies an area dispel to clear skeletons.
Additional:
* EMP allows Invoker to burn Wraith King's mana to prevent Reincarnation from triggering (only until Wraith King gets his Aghanim's Shard).
* Ice Wall and Cold Snap are particularly crippling for Wraith King as they allow to kite him very effectively, preventing him from dealing melee attack damage.

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

* Quas-Exort Invoker can win the mid lane easily against Alchemist because Quas regeneration will nullify Acid Spray's damage over time and Exort damage bonus will allow Invoker to out last hit Alchemist.

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

* Heroes with naturally low mana can be easily shut down by EMP: Sven, Tiny, Wraith King, Omniknight

* Heroes with long animations can be frequently interrupted with Cold Snap: Earthshaker, Monkey King, Shadow Fiend Lina

* 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.

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.

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

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

* Invoker's EMP is extremely effective against Earthshaker due to his low natural mana.

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

* Heroes with high armor and durability can be exceptionally hard for Bloodseeker to bring down: Dragon Knight, Axe

* 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.

* 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.

* 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.
* Axe is a natural buyer of Blade Mail and Riki players generally do not buy lifesteal, causing you to kill yourself when attacking due to your tiny HP pool.

* Cold Embrace is the perfect setup for all his nukes - Chaos Meteor, EMP and especially global Sun Strike.

* EMP is a large mana burn nuke which can hit Medusa's Mana shield with enough damage to lose even more mana.
* Deafening Blast disarms Medusa's ability to deal pseudo-AOE damage during teamfights.
* Cold Snap allows the opposing team to repeatedly stun Medusa in short succession, preventing her from successfully casting her ultimate due to its long cast time.
Additional:
* EMP allows Invoker to burn Medusa's mana to weaken Mana Shield.
* Medusa's lack of mobility makes her easy to kite with Invoker's spells.

* Axe forces Bristleback to turn around with Berserker's Call, allowing allies to attack him without fear of his passive.

* Heroes with global abilities can give Legion Commander's opponent an edge in Duels from anywhere on the map: Nature's Prophet, Ancient Apparition, Zeus, Invoker, Treant Protector

Additional:
* Invoker's spells will disable and destroy Legion Commander while she's locked in a Duel.

* 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.

* Cold Snap can prevent Timbersaw from using both Timber Chain and Chakram due to the frequent stuns interrupting the lengthy cast animations, as well as stopping him mid-chain. This can negate Timbersaw's attempts to escape or dole out extra ability damage.
* Later in the game, Invoker's heavy magical and pure damage can be difficult to avoid, meaning Timbersaw's armor is less useful.

* Heroes that can gain vision over trees to catch Tinker: Invoker, Shadow Demon, Batrider

Additional:
* Tinker is relatively helpless against Invoker, as his Rearm and Boots of Travel can be easily interrupted by Invoker's long range disables, even if he blinks away.

* 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

* Tornado allows Invoker to purge Necrophos's Ghost Shroud, nullifying any benefits he could get out of it
* EMP allows Invoker to burn Necrophos's mana, preventing him to use his abilities constantly

* Tornado dispels Guardian Angel from multiple targets.
* Guardian Angel is generally useless against Invoker as he primarily relies on magical damage.
* EMP depletes Omniknight's already small mana pool.
* Invoker's many disables keep Omniknight's team occupied until Guardian Angel times out.

* Pudge, Legion Commander and Axe will make the match a living hell for you, since they are known for surprise attacks from the fog and quickly killing low HP heroes. They can also interrupt your channeling, Legion being especially problematic, as she can use Press the Attack on an ally who is hexed as well.

* 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.

* Heroes who rely on fast attack speed will also trigger Counter Helix frequently: Faceless Void, Troll Warlord, Anti-Mage, Juggernaut, Arc Warden, Morphling

Additional:
* Magnetic Field doesn't provide a protection against Berserker's Call and Counter Helix and his high attack speed together with Tempest Double will often trigger Counter Helix.

* 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.
