* 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 can destroy Ember Spirit both on the line and in the game. It will be extremely difficult for Ember Spirit to finish off the creeps, because Huskar will not let him approach them, and if Ember Spirit does come up, Huskar just shuts him up with his Burning Spear and Ember Spirit will have to go to the base or bring himself treatment, or continue to stand and die. In all cases, Ember Spirit will go into negative
Additional:
* Ember Spirit does minimal damage to Huskar until the very late game.

* 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, Medusa, Dawnbreaker.

* The pure damage provided by Purification is a great addition for killing Ember Spirit, as well as a good way of saving teammates.
* Guardian Angel will temporarily save his allies from Sleight of Fist's physical damage, and Ember Spirit is not a hero that will get Orchid Malevolence to counter it.

* 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, Medusa, Dawnbreaker.

* Oracle can shut down both of Ember's early game abilities. Fortune's End can dispel Flame Guard on Ember Spirit and Searing Chains on allies.
* When Ember Spirit is affected by Fortune's End, his Fire Remnants move at 0 movement speed.
* Disarming him with Fate's Edict does affect Ember's Sleight of Fist ability, possibly making him useless for a few seconds in the late game without a dispel or spell immunity. This is especially good if he has a rapier or two. However, positioning for this is difficult when Ember plays far back.

* 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, Medusa, Dawnbreaker.

* Using X Marks the spot Kunkka can prevent Ember Spirit from escaping with Activate Fire Remnant, until he purchase Eul's Scepter of Divinity or Linken's Sphere.

* Any hero who can survive Magnus's initiations and manfight him: Huskar, Faceless Void, Weaver, Abaddon, Troll Warlord, Alchemist, Dragon Knight, Night Stalker, Viper.

* Faceless Void is one of the best heroes against Ember Spirit, providing a lot of ways of dealing with him. Ember Spirit becomes a lot weaker if affected by Time Dilation, as he can no longer spam Sleight of Fist.
* Chronosphere is also a reliable lockdown for Ember Spirit, although it can be evaded sometimes by Activate Fire Remnant. Additionally, Void can easily negate Sleight of Fist damage with Time Walk.
* And finally, Void is a great Diffusal Blade carrier. Not only Manabreak's physical damage not negated by Flame Guard, but it also burns Ember Spirit's mana. That, in turn, prevents him from escaping if he survived Chronosphere.

* Illusory Orb serves as a good scouting tool whenever Magnus is hiding in the trees, allowing Puck to warn its allies and disrupt his initiation attempts.
* Phase Shift allows Puck to dodge Shockwave when timed correctly.
* Even after Magnus successfully uses Reverse Polarity and Skewer Puck's teammates, Puck can usually counter-initiate using both Waning Rift and Dream Coil.
* Magnus cannot use Skewer when he is affected by Dream Coil, making him vulnerable to follow-up disables.
* Puck usually gets its own Blink Dagger as well, which makes it harder to lock down unless Magnus commits Reverse Polarity only for Puck.

* Any Hero with high mobility will be neutralized by dream coil: Queen of Pain, Storm Spirit, Ember Spirit, Lycan, Bloodseeker, Anti-Mage, Timbersaw.

* 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, Medusa, Dawnbreaker.

* Ember Spirit has a small mana pool, which is why QW-Invoker can burn it out very effectively with his own E.M.P., do not give Ember Spirit the opportunity to play with his abilities and cause damage with them in a fight.
* QW-Invoker Destroys Ember Spirit's Flame Guard with his own Tornado, which is why Ember Spirit cannot defend against Invoker's strong magic damage.

* Heroes that have an escape that doesn't disjoint projectiles: Mirana, Faceless Void, Magnus

* Impetus will deal huge amounts of damage when he uses a Fire Remnant to escape.
* Flame Guard is useless against Impetus as it deals Pure damage.
* Enchant can be used to dispel Flame Guard.

* 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, Medusa, Dawnbreaker.

* Batrider has huge damage from his Sticky Napalm and hand strikes on the target, with this effect. And Ember Spirit not only has a small reserve of health, but also has a melee type of attack. If these two collide on the center line, then Ember Spirit will have to finish off several creeps from afar with a Sleight of Fist, otherwise he will lose a lot of health from long-range Batrider attacks under Sticky Napalm, and possibly even kill, because Ember Spirit does not have the ability to interrupt Batraider with his damage if he decides to attack
* Ember Spirit is a very tasty target for Flaming Lasso, because it has a small reserve of health, and all the power lies in the abilities that Flaming Lasso forbids using, this can help the Batraider team quickly deal with the unpleasant "jumping" Ember Spirit in a fight if he gets into Flaming Lasso

* Heroes who build mana boosting items but have low mana regeneration are especially vulnerable against Mana Break and Mana Void: Timbersaw, Slark, Shadow Fiend, Clinkz, Bristleback Nyx Assassin, Magnus

Additional:
* Anti-Mage can survive against Magnus's Reverse Polarity thanks to the high magic resistance from Counterspell.
* Should Anti-Mage survive Magnus's Reverse Polarity and Skewer, Magnus will have exhausted most of his skills and items, preventing him from defending himself against any counter initiation or a follow-up from a blink escape.
* Mana Break can deplete Magnus's much needed mana.
* Anti-Mage's Blink will make him a very hard target or Magnus to use Reverse Polarity on, having to solo ult him later on in the game or leave him out of the Reverse Polarity.
* Overall, any attempt for Magnus to gank Anti-Mage will hurt him more than it will hurt Anti-Mage.

* Anti-mage is potentially good against Ember Spirit since he can burn Ember Spirit's mana, prevent him from escaping or using his skill. Anti-Mage has high magic resistance, which will reduce most of the damage from Ember Spirit's skill set. However, Anti-Mage lacks any form of stuns or lockdowns, and may struggle to kill Ember Spirit if he still has some mana left.

* Tinker can break Magnus's Blink Dagger using March of the Machines and Heat-Seeking Missile, therefore delaying any initiation or making Magnus use Skewer or Force Staff to initiate. His {Ability ID:Defense Matrix|Tinker} will decrease the duration of Reverse Polarity and can also be cast on all of his teammates with {Ability ID:Rearm|Tinker}. Tinker usually gets his own Blink Dagger as well, which makes him harder to lock down unless Magnus commits Reverse Polarity only for Tinker.

* Treant Protector can usually scout out Magnus in the trees with Eyes in the Forest and disrupt his initiation attempts. He can also counter Magnus' initiation with Overgrowth.

* Dark Ascension reduces vision for the enemy team, which makes it more difficult for Magnus to initiate with Blink Dagger and Reverse Polarity. It is also more likely that Night Stalker will scout out Magnus with Aghanim's Scepter and a Gem of True Sight, after which he can silence Magnus with Crippling Fear.

* Lone Druid becomes unkillable and impenetrable for Ember Spirit on the central line, as it has a huge reserve of health from the Summon Spirit Bear and a large regeneration from Spirit Link, which is why Sleight of Fist practically does not break through either one or the other on the line, and Lone Druid at this time can easily expel Ember Spirit from the line, push and gain gold and level
* Entangling Claws and Savage Roar abilities completely disable Ember Spirit's ability to dodge abilities or get out of an unpleasant fight for him on Fire Remnant, which can give the Lone Druid team the opportunity to kill him

* Even if Wraith King dies after Magnus disables him, Magnus' entire team will be slowed and vulnerable for counter-initiation.

* The pure damage provided by Arcane Orb is a great addition for killing Ember Spirit.
* Astral Imprisonment fully negates all magic damage of Flame Guard and Searing Chains and will temporarily save himself from Sleight of Fist's physical damage, and Ember Spirit is not a hero that can counter these skills.

* Ember Spirit's Flame Guard provides no protection against Clinkz's physical damage output.
* Ember Spirit's low armor and health make him easy to kill quickly if a teammate can hold him down.
* If Clinkz has farmed an item that can disable, he can sneak up to and hunt down Ember Spirit while he farms or split pushes alone.

* Phoenix will usually be on the sidelines or further back ready to use Sun Ray. Even after Magnus successfully uses Reverse Polarity and skewer Phoenix's teammates, Phoenix can usually counter-initiate using all of its abilities.

* Global Silence and Last Word can prevent Ember Spirit from casting Activate Fire Remnant to escape.
* Glaives of Wisdom also provide high pure damage that is not negated by Flame Guard.
* Arcane Curse is also a potent harassing tool in the laneing stage as its cooldown is lower than Flame Guard's.

* Magnus is not tanky and struggles against burst damage, something Primal Beast excels at in the early-to-mid game. Primal Beast is also able to out-damage Magnus's Empower and can even contribute to his Uproar stacks.
* Using Skewer to drag Primal Beast while he is trampling will count as movement and will trigger a rapid number of slams, which could prove lethal to Magnus.

* If Luna can use Eclipse in anticipation, Magnus will be killed before he can even manages to cast Reverse Polarity.
* Aghanim's Scepter upgraded Eclipse is a very good counter-initiation tool against Magnus when he casts Reverse Polarity, granted as long as Luna can cast it from safe distance.

* Lion possesses two strong disables in Earth Spike and Hex and heavy magic burst with Finger of Death which help lock him down and prevent him from escaping with Activate Fire Remnant. When getting his Blink Dagger Lion can punish Ember Spirit's overextension immediately, or initiate a fight on him with disables.

* Spectre disables Magnus' Blink Dagger using her ultimate, and later into the game can usually outlive Reverse Polarity's duration.
Additional:
* Spectre can use Haunt to intercept and disrupt Magnus's initiation attempts.
* Spectral Dagger can severely slow down Magnus after he uses Skewer.
* Magnus often travels alone when he is trying to initiate, so Desolate can be very effective against him.
* In late game, Spectre can survive Reverse Polarity initiation thanks to Dispersion.

* Similar to Night Stalker, Venomancer can simultaneously scout Magnus hiding in trees and put Blink Dagger on cooldown with Plague Ward, which gives Magnus problems when trying to blink in and initiate.
Additional:
* Venomancer can simultaneously scout Magnus hiding in trees and putting Blink Dagger on cooldown with Plague Wards, which makes Magnus real problems to blink and initiate.

* Ember Spirit cannot use his Activate Fire Remnant to escape while affected by Doom.

* Any hero who can survive Magnus's initiations and manfight him: Huskar, Faceless Void, Weaver, Abaddon, Troll Warlord, Alchemist, Dragon Knight, Night Stalker, Viper.

* 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, Medusa, Dawnbreaker.

* Any hero who can survive Magnus's initiations and manfight him: Huskar, Faceless Void, Weaver, Abaddon, Troll Warlord, Alchemist, Dragon Knight, Night Stalker, Viper.

Additional:
* Most of Magnus's abilities except Empower will trigger damage through Corrosive Skin.
* Poison Attack and Viper Strike can slow Magnus during Skewer, as well as putting his Blink Dagger on cooldown, preventing him from initiating or re-initiating.

* Any hero who can survive Magnus's initiations and manfight him: Huskar, Faceless Void, Weaver, Abaddon, Troll Warlord, Alchemist, Dragon Knight, Night Stalker, Viper.

* Heroes with blink or movement abilities, which are disabled by Pounce's leash: Anti-Mage, Earth Spirit, Faceless Void, Magnus, Mirana, Monkey King, Morphling, Pangolier, Phantom Assassin, Phoenix, Puck, Queen of Pain, Riki, Sand King, Spirit Breaker, Timbersaw, Tusk.

* Queen of Pain can be a good hero for dealing with Ember Spirit with Orchid Malevolence, her pure damage nuke in Sonic Wave and a slow in Shadow Strike. However, Queen of Pain can be punished by Ember Spirit, as his Searing Chains prevents her from getting Blink off.

* 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, Medusa, Dawnbreaker.

* Heroes that have high health but little to no magic resistance are easy prey for Necrophos, as no matter how high they build their health up, Reaper's Scythe will kill them outright as long as they fall under a certain threshold, and Heartstopper Aura will deal the same amount of damage regardless, decaying their health the longer they stay within range. As such, Strength heroes like Chaos Knight, Centaur Warrunner or Magnus are good targets for his ultimate.

* 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, Medusa, Dawnbreaker.

* Disruptor can disable Magnus's Blink Dagger using Thunder Strike during a considerable duration, disrupting his initiation attempts.
* Glimpse brings Magnus back after he escapes with Skewer and/or Force Staff.
* Static Storm if used on a fight can prevent Magnus from using Reverse Polarity after he jumps in.

* With Vendetta, Nyx Assassin can move closely to Ember Spirit when he's farming with his Flame Guard and use Spiked Carapace with Impale to provide a reliable and long disable.
Additional:
* Spiked Carapace can be easily triggered by Flame Guard or Battle Fury, setting up a deadly Impale.

* Jakiro's abilities deal damage over time, which can disrupt Magnus's attempts to initiate with Blink Dagger and Reverse Polarity.
* Macropyre not only disables Blink Dagger for a considerable duration, but can also destroy Trees, revealing Magnus's cover and position.

* Plasma Field can slow Magnus during Skewer, and when combined with Eye of the Storm, will potentially disable his Blink Dagger, preventing him from initiating.
* Static Link drains the bonus damage from Empower. However, it can be broken by Skewer and/or Force Staff.
* Storm Surge gives Razor and his allies high mobility needed to avoid Shockwave & Reverse Polarity.

* Shadowraze can easily remove the protection from Flame Guard and kill Ember Spirit due to his low health.
* Ember Spirit is very vulnerable to physical damage from Necromastery.

* All of Magnus's spells are perfect for Rubick to steal, especially Reverse Polarity for a counter-initiation.
* Telekinesis is one of the best instant-disables in the game, completely ruining Magnus's initiation.
Additional:
* Reverse Polarity, if stolen, can counter-initiate Magnus's team and put them at a huge disadvantage.
* Magnus himself is positioned at the center of teamfight after casting Reverse Polarity, and will be stunned by Rubick's stolen one most of the times.
* Bear in mind that Magnus will usually cass Skewer or Shockwave after he casts the ultimate, so the time windows left for steal can be short.
* Shockwave allows Rubick to farm fast, and also deals decent AoE damage in teamfights.
* Empower can be casted on the carry (especially affective if melee) on Rubick's team to accelerate their farm or amplify their damage in fights.
* Skewer could be used to displace enemy or escape from danger.
* Telekinesis can relocate the enemy in front of Rubick for Skewer.
* With Quick Cast enabled, Rubick can stop the enemy Magnus with careful prediction using Telekinesis to interrupt Horn Toss - Skewer combo.

* Heroes with high mobility can be prevented from using it to their advantage with Earthbind, even if they pack a dangerous arsenal: Earth Spirit, Ember Spirit, Storm Spirit, Nature's Prophet, Phantom Assassin, Riki, Anti-Mage, Weaver.
* See items and abilities disabled by roots

* Shrapnel can sometimes scout out Magnus and also place his Blink Dagger on cooldown. Aside from that, Sniper likes to stay far back behind enemy lines, so it's difficult to catch him with Reverse Polarity unless you already have vision on him and can Skewer him to the rest of his team.

* Heroes who take a long time to become strong are in for a rough mid game, such as Outworld Destroyer, Magnus, Medusa, and Anti-Mage.

* 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, Medusa, Dawnbreaker.

* With Aghanim's Scepter, Broodmother will gain access to Spinner's Snare, which will allow her to create invisible lines on her webs from Spin Web that will root, deal damage over time, and reveal enemy heroes if they unwittingly step on them. This allows Broodmother to keep her allies alerted on heroes who rely on invisibility-themed and movement-themed abilities and items to surprise enemy heroes and disrupt ganking attempts of enemy heroes: Phantom Assassin, Nyx Assassin, Mirana, Bounty Hunter, Templar Assassin, Riki, Spirit Breaker, Anti-Mage, Tusk, Ursa, Nature's Prophet, Enigma, Void Spirit, Magnus etc.

* Heroes who rely on high mobility are especially vulnerable to Primal Roar: Storm Spirit, Ember Spirit, Queen of Pain.

* Zeus can easily find Magnus who is often hiding in the trees with Thundergod's Wrath and Lightning Bolt, which allows him to warn allies and disrupt his initiation attempts.

* Storm Spirit is not only a potent Orchid Malevolence carrier, his Electric Vortex provides an additional disable and Overload provides a great slow. When paired with Static Remnant, they can cut through Flame Guard fast.
* Ball Lightning not only provides great initiation upon Ember Spirit from any position anytime, but also helps dodge Sleight of Fist.

* Magnus has very mediocre damage against Alchemist, because he can survive the stun duration of Reverse Polarity with Chemical Rage.

* 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.

* 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, Medusa, Dawnbreaker.

* Rupture deals extra damage to Magnus during Skewer or Force Staff, preventing him from escaping or counter-initiating, forcing him to invest on a Linken's Sphere.

* 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, Medusa, Dawnbreaker.
