Juggernaut
* 
Blade Fury will not protect Juggernaut against Chronosphere or Time Lock.
* Faceless Void can Time Walk out of the range of 
Omnislash at all points of the game and with ease.
Lifestealer
* Chronosphere provides excellent lockdown against 
Rage.
* Faceless Void's Time Lock stops Lifestealer from getting health regeneration from auto-attacks
Juggernaut
* While Blade Fury is on cooldown, Juggernaut can be easily killed by a standard 
Chaos Bolt & 
Reality Rift combo.
* 
Phantasm illusions can tank Omnislash.
Lifestealer
* Level 20 talent allows Reality Rift to bypass spell immunity provided by Rage, thus negating the advantage Lifestealer has in his kit.
* The fact that Lifestealer lacks wave clearing and reliable lockdown makes it difficult to fight Chaos Knight's illusions.
* 
Feast is largely negated by Chaos Knight's high burst damage from Chaos Strike.
Additional:
* 
Chaos Strike is a strong burst damage passive that allows Chaos Knight to stand up and even survive Lifestealer's attacks. Level 20 Talent: Reality Rift Pierces Spell Immunity allows him to burst down Lifestealer even while he is in Rage.
* Lifestealer's single-target nature will struggle against Chaos Knight's Phantasm illusions and will be forced to itemize for them.
Juggernaut
* Heroes that rely on right-clicks will find themselves unable to damage opponents seriously after being affected by Static Link, like 
Sven, 
Bloodseeker, and 
Juggernaut.
Lifestealer
* Razor's highly mobile nature allows him to control Lifestealer from a distance. As well, Lifestealer is already slow in comparison due to his lack of disables and move speed. Lifestealer is also an ideal target for 
Static Link, for its ability to pierce magic immunity and damage steal, which can render Lifestealer's Feast useless.
* 
Plasma Field can slow Lifestealer from a distance and force him to cast Rage too early.
* 
Eye of the Storm pierces magic immunity, deals physical damage, and reduces armor, allowing Razor to easily stand up to Lifestealer.
Additional:
* Static Link cannot be dispelled by Rage or 
Infest, so Razor will be able to track Lifestealer down during an attempted escape.
* Storm Surge makes it hard for Lifestealer to catch Razor.
* Static Link can stop 
Open Wounds from getting any additional lifesteal, but keep in mind Lifestealer can still utilize Feast.
* Eye of the Storm penetrates the spell immunity of Rage.
Juggernaut
* Heroes with escaping and disjointing abilities can be good against Juggernaut:
Anti-Mage 
Riki, 
Queen of Pain, 
Puck, 
Storm Spirit, 
Ember Spirit, 
Slark etc.
Lifestealer
* Lifestealer cannot use Rage, Infest or Open Wounds when affected by Smoke Cloud's silence, and Feast cannot heal him effectively because of the blind, leaving him very weak both offensively and defensively.
* Infest ganks are harder when the enemy team has a Riki, as there are often only four heroes on the map that you can initiate on.
Juggernaut
* Heroes with escaping and disjointing abilities can be good against Juggernaut:Anti-Mage Riki, Queen of Pain, Puck, Storm Spirit, Ember Spirit, Slark etc.
Additional:
* Blade Fury does not offer any protections against 
Essence Shift, as it can go through spell immunity and reduces attribute.
* Slark can pounce away from Juggernaut and he cannot prevent or chase slark.
* 
Shadow Dance prevent Juggernaut from using Omnislash altogether, while regen himself at a higher rate. Slark can freely hit juggernaut without any fears of retaliation.
Lifestealer
* Shadow Dance allows Slark to attack Lifestealer for its duration without any way for Lifestealer to fight back, allowing him to steal his stats with Essence Shift, which also reduces Lifestealer's strength and, therefore, health pool.
* Slark can easily escape Lifestealer with 
Pounce, and can avoid Open Wounds with 
Dark Pact should Lifestealer be forced to itemize for it.
* Slark commonly buys a 
Silver Edge, which can break Lifestealer's Feast, severely diminishing his damage output and lifesteal.
* 
Depth Shroud from 
Aghanim's Shard allows Slark to save both, himself and his allies with Shadow Dance while also allowing them to fight back against Lifestealer.
Juggernaut
* Primal Beast can use Uproar to tank a portion of Omnislash, making him much more likely to survive it. Primal Beast can also charge away from Omnislash using Onslaught as the spell ends.
* Blade Fury will never do more damage than Uproar once the stacks are activated.
* Primal Beast is very commonly buying items that are good against Juggernaut, such as 
Ethereal Blade and 
Heart of Tarrasque.
* Primal Beast has one of the few ultimates that can prevent Juggernaut from spinning away with a teleport.
Lifestealer
* Special mention to 
Lifestealer who can use Rage to prevent Trample damage, but Primal Beast's ultimate can still be casted during the spell.
Juggernaut
* 
Nature's Call can be used to tank Omnislash in the early to mid game due to their high health pool combined.
* 
Sprout can trap Juggernaut, even if he is using Blade Fury. Aghanim's Shard upgraded Sprout can also prevent Juggernaut from escaping if he buys 
Battle Fury.
* Once Nature's prophet reach lv 20 with leash talent on Sprout, he can stop Juggernaut from escaping with Blade Fury and TPing away.
* Nature's Prophet can farm and push much faster than Juggernaut, acquiring map control before he can do much.
Lifestealer
* Heroes with summons: 
Lycan, 
Broodmother, 
Visage, 
Nature's Prophet, 
Warlock.
Juggernaut
* Illusion-based heroes are effective against Omnislash and Juggernaut's single-targeted damage: 
Naga Siren, 
Chaos Knight, 
Terrorblade,
Phantom Lancer.
Lifestealer
* Lifestealer will struggle to deal with Phantom Lancer's illusions and will either be forced to use his abilities too quickly, or itemize too heavily for them.
* Phantom Lancer commonly builds 
Diffusal Blade, which poses a large problem to Lifestealer and his low mana pool, and can shut him down from even casting his abilities.
Additional:
* Aside from his ultimate, Lifestealer has no AoE abilities to deal with Phantom Lancer's illusions, nor does he have the mobility to escape 
Phantom Rush.
* 
Doppelganger dispels Open Wounds.
* Phantom Lancer usually builds Diffusal Blade, which a problem for a low already mana hero like Lifestealer.
Juggernaut
* 
Fury Swipes is not protected by Blade Fury and allows Ursa to harass Juggernaut anytime.
* 
Enrage reduces the damage taken from Omnislash.
Lifestealer
* Lifestealer will struggle to duel Ursa in all stages of the game due to Fury Swipes, which pierces magic immunity. Ursa can also stand up to Lifestealer with Enrage, which dramatically reduces incoming damage and further delay Lifestealer's Feast.
Additional:
* Lifestealer's Feast will most likely not out-heal the damage from Fury Swipes and Overpower in the early to mid game.
Lifestealer
* With 
Aghanim's Scepter upgraded Infest, Lifestealer can use it on enemy heroes to attack them and disarm them from inside, even if they are spell immune, which can give him the edge over the heroes he's weak against like 
Ursa, 
Phantom Assassin, Terrorblade or 
Troll Warlord.
Juggernaut
* Enigma's Eidolons from 
Demonic Conversion can help soak Juggernaut's Omnislash in the early game, mitigating the damage and wasting it on disposable summons. Should Juggernaut choose to kill Enigma's Eidelons with Blade Fury, he will leave himself open to Enigma's disables.
* Enigma's 
Black Hole and 
Midnight Pulse's damage and disable can pierce through Juggernaut's Blade Fury.
Additional:
* Enigma's Eidolons can absorb Omnislash damage, wasting its damage potential.
* Black Hole and Midnight Pulse damage pierces Blade Fury, especially when he tries to escape with it.
Lifestealer
* Lacking any stun and being heavily dependent on his physical attacks and spell immunity, Lifestealer has no way to stop Black Hole, assuming he does not initiate Enigma first with 
Abyssal Blade.
* Enigma's Black Hole and Midnight Pulse damage can pierce through Lifestealer's Rage.
* However, if Lifestealer manages to get Aghanim's Scepter and combines it with Abyssal Blade, he will be able to disable Enigma's Black Hole inside him with Infest and he will be able to help his allies recover themselves from Enigma's initiation with Open Wounds if Lifestealer gets Aghanim's Shard.
Additional:
* Lacking any stun and being heavily dependent on his physical attacks and spell immunity, Lifestealer has no way to stop Black Hole, assuming he does not initiate Enigma first with Abyssal Blade.
* Enigma's Black Hole and Midnight Pulse damage can pierce through Lifestealer's Rage.
* However, if Lifestealer manages to get Aghanim's Scepter and combines it with Abyssal Blade, he will be able to disable Enigma's Black Hole inside him with Infest and he will be able to help his allies recover themselves from Enigma's initiation with Open Wounds if Lifestealer gets Aghanim's Shard.
Lifestealer
* Enigma lacks burst damage, and that makes him vulnerable to heroes who can recover themselves and turn the fight around to their advantage after Enigma finishes his initiation: 
Faceless Void, Terrorblade, Ursa, 
Weaver, Broodmother, Slark, 
Abaddon, 
Wraith King, Lifestealer.
Juggernaut
* Troll Warlord's ability to attack as a ranged hero allows him to destroy Juggernaut's 
Healing Ward from afar.
* Battle Trance, when activated during Omnislash, allows Troll Warlord to survive the full duration of Omnislash and retaliate once it is over.
Lifestealer
* Lifestealer is a susceptible target to 
Fervor due to his non-mobile nature and lack of disables. Troll Warlord's ranged 
Berserker's Rage can also be used to kite Lifestealer safely. The root from its melee form also pierces magic immunity, which can potentially keep Lifestealer in place even while he is in Rage.
* Both 
Whirling Axes (melee) and 
Whirling Axes (ranged) can force Lifestealer to cast Rage too quickly and allow Troll Warlord to change strategies mid-fight, especially thanks to their separate cooldowns.
* 
Battle Trance allows Troll Warlord to survive Lifestealer's Feast and turn the fight in his favor.
Additional:
* The passive armor provided by Berserker's Rage makes Troll Warlord resilient to Feast in early game.
* The 60% miss chance given by Whirling Axes (Melee) is useful when Rage is not active.
* Battle Trance can purge Open Wounds, negating a large amount of Lifestealer's sustain in fights.
Lifestealer
* With Aghanim's Scepter upgraded Infest, Lifestealer can use it on enemy heroes to attack them and disarm them from inside, even if they are spell immune, which can give him the edge over the heroes he's weak against like Ursa, Phantom Assassin, Terrorblade or Troll Warlord.
Juggernaut
* 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.
Lifestealer
* Many physical-only single-target heroes like Lifestealer, Sven, Wraith King, Phantom Assassin, 
Templar Assassin can have their damage mitigated by Cold Embrace.
Juggernaut
* With the exception of Magic Missile (unless the player takes the Level 25 Talent "Magic Missile Pierces Spell Immunity"), all of Vengeful Spirit's spells ignore Spell Immunity. This also makes her good against heroes with built-in Spell Immunity like Lifestealer or Juggernaut or heroes that tend to pick up 
Black King Bar, like Sven.
Lifestealer
* With the exception of Magic Missile (unless the player takes the Level 25 Talent "Magic Missile Pierces Spell Immunity"), all of Vengeful Spirit's spells ignore Spell Immunity. This also makes her good against heroes with built-in Spell Immunity like Lifestealer or Juggernaut or heroes that tend to pick up Black King Bar, like Sven.
Juggernaut
* Low-health, normally mobile carries who rely entirely on raw attack damage are vulnerable to Bane's nukes and disables: Anti-Mage, 
Clinkz, 
Drow Ranger, Faceless Void, 
Gyrocopter, Juggernaut, 
Meepo, 
Mirana, 
Monkey King, 
Morphling, Phantom Assassin, Phantom Lancer, Riki, 
Shadow Fiend, Slark, 
Sniper, Terrorblade, Troll Warlord, Weaver.
Additional:
* 
Fiend's Grip pierces spell immunity, rendering Blade Fury nearly useless.
Lifestealer
* Heroes with spell immunity can still be disabled by Fiend's Grip and damaged by Brain Sap: Juggernaut, Lifestealer, 
Pangolier.
Additional:
* 
Enfeeble can weaken Lifestealer's Feast and may force him to cast Rage too quickly or itemize to dispel it.
* Fiend's Grip pierces through magic immunity and allows him to disable Lifestealer while in Rage.
Juggernaut
* Chaotic Offering can stop heroes who like to use spell immunity and teleport scrolls to safely farm during the early to mid game, since it stuns and also goes through spell immunity. Notable examples: Juggernaut, Lifestealer.
Lifestealer
* Heroes with summons: Lycan, Broodmother, Visage, Nature's Prophet, Warlock.
Juggernaut
* 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.
Additional:
* Be ready to save an ally from Omnislash with your Disruption.
* Spawning Juggernaut's illusions is a great deal, as his base attack time is low and he has a critical strike. Illusions will benefit from both.
* Demonic Purge will prevent Juggernaut's desperate attempt to flee using Blade Fury. However, it cannot stop him if he is using 
Town Portal Scroll.
Lifestealer
* Melee carries such as Sven, Ursa or Lifestealer can be slowed and easily kited with Demonic Purge.
Juggernaut
* Heroes with escaping and disjointing abilities can be good against Juggernaut:Anti-Mage Riki, Queen of Pain, Puck, Storm Spirit, Ember Spirit, Slark etc.
Lifestealer
* Heroes with escape abilities: Anti-Mage 
Dark Seer Slark Storm Spirit 
Windranger Weaver can kite Lifestealer due to him having no lockdown.
Juggernaut
* Heroes with escaping and disjointing abilities can be good against Juggernaut:Anti-Mage Riki, Queen of Pain, Puck, Storm Spirit, Ember Spirit, Slark etc.
Lifestealer
* Heroes with escape abilities: Anti-Mage Dark Seer Slark Storm Spirit Windranger Weaver can kite Lifestealer due to him having no lockdown.
Juggernaut
* Heroes with high armor and/or durability can handle Juggernaut's ultimate, such as Sven and 
Dragon Knight.
Lifestealer
* Heroes that rely on physical damage are ineffective against Dragon Knight due to his high armor: Phantom Assassin,Bloodseeker, Lifestealer, Troll Warlord, Sven
Juggernaut
* 
Guardian Angel completely negates all physical damage, including Omnislash.
Additional:
* Omnislash (and 
Swiftslash) is blocked by Guardian Angel.
Juggernaut
* Omnislash spreads on both the bear and the druid, allowing them to survive.With enough levels,the bear can soak the ability alone and possibly dragging him to a dangerous location.
* Juggernaut cannot manfight the duo in the early game,because of their tankiness. If opposed in lane,Lone Druid can shut him down.
Juggernaut
* 
Duel pierces spell immunity and forces him to attack Legion Commander, making him unable to use Omnislash.
Lifestealer
* Clinkz relies heavily on the physical damage provided by 
Burning Barrage and 
Searing Arrows, which completely overrides the capabilities of Rage.
* Lifestealer's lack of disables will struggle to pin Clinkz down while in 
Skeleton Walk, and can allow Clinkz to kite him.
Lifestealer
* Though 
The Swarm can be blocked by Rage, it can be used to lower Lifestealer's already low armor, making him even more vulnerable to physical damage while Rage is on cooldown.
* Lifestealer has no strong disables on his own and thus cannot catch up with nor escape from Weaver's 
Shukuchi.
* Lifestealer's reliance on meticulous auto-attacks will not help against 
Time Lapse, which can undo Lifestealer's already slow build-up of damage. Aghanim's Scepter upgraded Time Lapse can also be used to save allies from getting killed by Lifestealer, but that will require targeting the allied hero rather than just pressing the button that will trigger the Time Lapse.
Additional:
* Open Wounds's slow is ignored by Shukuchi.
* Lifestealer has no other lockdown and relies on being on top of enemies; Weaver can kite him with ease.
Juggernaut
* Drow Ranger can use Gust to push back Juggernaut before he can get in range to use Omnislash or Blade Fury.
Juggernaut
* 
Decrepify prevents Omnislash damage, until Juggernaut gets a 
Nullifier.
* Without a disable, Pugna's high movement speed makes it harder to chase him with Blade Fury.
* Juggernaut has low mana and his skills cost large amount of mana. 
Nether Ward will hurt him more and even worse, the damage from the ward is inflicted before the Spell immunity provided by Blade Fury.
Additional:
* Decrepify is the perfect tool against Omnislash until he gets a Nullifier, and even then he will probably waste a couple of slashes before he uses it.
* Without an extra disable, Pugna's high movement speed makes it impossible to chase him with Blade Fury.
* Unlike some other carries like Slark or Phantom Assassin, Juggernaut's spells cost a hefty amount of mana and he will seriously get hurt by Nether Ward. Don't forget the damage from the ward is inflicted before the spell immunity is provided by Blade Fury.
Juggernaut
* All abilities from Juggernaut (except Blade Dance) is very vulnearable steal to Rubick's 
Spell Steal.
Additional:
* Juggernaut looks like a carry that 
Rubick can hardly manfight, and it is surely the case that Rubick needs the assistance from his team to overwhelm the hero. However, his skills can be of great use for Rubick if used at the right occasions.
* Blade Fury is a great farming ability with low cooldown. What is bizarre about this ability is that it grants Rubick spell immunity and constant damage around him (movement speed buff with Aghanim's Shard). In early to mid game when all heroes has relatively low physical damage, the spell allows Rubick to become a temporary tank that enemy needs to run away from, extending Rubick's early killing potential.
* 
Telekinesis can throw a victim in range to eat up the damage from Blade Fury.
* Blade Fury can be stolen and used in a pinch to negate the damage from Blade Fury of Juggernaut. Note that with Aghanim's Shard Juggernaut can still deal damage to Rubick.
* Healing Ward, if stolen, serves as a magnificant healing tool within or after a teamfight. The constant area-of-effect healing helps greatly when your teammate is manfighting the enemy or escaping in a bad situation, and can even turn the fight around.
* Juggernaut is melee and cannot target an enemy Healing Ward easily unless he is in the midst of battle. Also, Juggernaut is not directly controllable during Omnislash and cannot attack Healing Ward.
* Omnislash is possibly the least useful spell Rubick can steal from Juggernaut. Although it is a good damage source in the early game, as a hero who seldom bulk up his physical damage, Omnislash falls quickly as the game goes on.
* It is worth mention that Omnislash could be used as an escape ability for Rubick with the help of 
Blink Dagger.
* Omnislash grants invulnerability at the midst of a fight. With quick reflex and judgement, Rubick can possibly dodge lockdowns and area disables, even steal a new spell when Omnislash is still on the fly.
Lifestealer
* Reverse Polarity pierces through Rage, wasting part of it's duration.
* Magnus is tanky and mobile, making it hard for Lifestealer to focus and kill him in all stages of a game.
Lifestealer
* Lifestealer is a great target for Morphling to use Morph, as he can use Rage to gain spell immunity and a movement speed boost.
* Morphling's high armor also makes Lifestealer's attacks do less damage.
Juggernaut
* In general, heroes that deal burst in multiple instances will trigger Borrowed Time and heal Abaddon for a large amount, such as 
Skywrath Mage, 
Techies, Juggernaut, 
Shadow Shaman, or 
Ogre Magi.
Juggernaut
* 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.
Juggernaut
* 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.
Juggernaut
* Heroes with escaping and disjointing abilities can be good against Juggernaut:Anti-Mage Riki, Queen of Pain, Puck, Storm Spirit, Ember Spirit, Slark etc.
Juggernaut
* Heroes with high armor and/or durability can handle Juggernaut's ultimate, such as Sven and Dragon Knight.
Additional:
* 
Warcry allows Sven to tank the damage from Omnislash due to its high armor gain.
* However Blade Fury provides spell immunity which blocks the stun from 
Storm Hammer.
Lifestealer
* Heroes with summons: Lycan, Broodmother, Visage, Nature's Prophet, Warlock.
Lifestealer
* Heroes with escape abilities: Anti-Mage Dark Seer Slark Storm Spirit Windranger Weaver can kite Lifestealer due to him having no lockdown.
Juggernaut
* Juggernaut's Omnislash is meaningless for Meepo who can share the damage across clones to save other allies.
Lifestealer
* Lifestealer's Rage and Open wounds become useless when Meepo has 4 or more clones, as Ransack will heal Meepo too quickly for Lifestealer to take down.
Lifestealer
* Lifestealer is not affected by Earthbind or Poof during Rage, making him a difficult target to work around.
Juggernaut
* Heroes with escaping and disjointing abilities can be good against Juggernaut:Anti-Mage Riki, Queen of Pain, Puck, Storm Spirit, Ember Spirit, Slark etc.
Lifestealer
* Heroes with high physical damage can damage Lifestealer more than he can heal: 
Bristleback, Clinkz, 
Luna,Shadow Fiend, 
Slardar, Terrorblade
Lifestealer
* Heroes with summons: Lycan, Broodmother, Visage, Nature's Prophet, Warlock.
Juggernaut
* 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.
Lifestealer
* Heroes with high physical damage can damage Lifestealer more than he can heal: Bristleback, Clinkz, Luna,Shadow Fiend, Slardar, Terrorblade
Juggernaut
* 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.
Lifestealer
* Heroes that lack burst damage will have a difficult time taking down Monkey King, and fare badly against Jingu Mastery: 
Legion Commander, Lifestealer, Weaver, Wraith King
Lifestealer
* Lifestealer's low mobility makes him easy to kite.
* Stone Gaze pierces Rage, wasting its cooldown and making Lifestealer unable to fight.
Juggernaut
* Heroes that build Diffusal Blade or can fit it well into their item build will also make Medusa much less tanky: Riki, Naga Siren, Terrorblade, Juggernaut, 
Spectre, Slark.
Lifestealer
* 
Ice Blast prevents Lifestealer from lifestealing and healing with Infest in fights.
Juggernaut
* Heroes with mobility/escape mechanisms to dodge Ancient Apparition abilites, or to easily jump on him: Riki, Queen of Pain, Phantom Assassin, Windranger, 
Bounty Hunter, 
Spirit Breaker, 
Night Stalker, Storm Spirit, Juggernaut, etc.
Juggernaut
* Illusion-based heroes are effective against Omnislash and Juggernaut's single-targeted damage: Naga Siren, Chaos Knight, Terrorblade,Phantom Lancer.
Lifestealer
* Terrorblade's illusions and ranged attacks in 
Metamorphosis can burst down Lifestealer very quickly.
* Terrorblade has low health due to his low strength gain, which reduces Feast's lifesteal and damage.
* Because Lifestealer can usually heal back HP in fights due to his innate lifesteal (and sometimes 
Armlet of Mordiggian), he is a great target for Terrorblade's 
Sunder.
* However, Aghanim's Scepter upgraded Infest can disarm Terrorblade and allow Lifestealer to attack him from inside while also increasing Lifestealer's health regeneration that can nullify effects of Sunder, even if Terrorblade is spell immune, which could potentially render Terorrblade useless in teamfights. And if Terrorblade cannot attack enemy heroes, he will go down very quickly.
Additional:
* Reflection's illusion carries Feast as well, making it useful to use against him.
* Feast cannot compensate for Terrorblade's incoming high damage, due to his low Strength gain.
* Open Wounds (requires Aghanim's Shard) is a lot harder to land on the real Terrorblade if he has illusions around him. But remember that Terrorblade's illusions from 
Conjure Image have different colors than other illusions which can be seen even by enemy team, and that can make it easy for Lifestealer to detect real Terrorblade unless Terrorblade buys 
Manta Style.
* Lifestealer relies on right-clicks to deal damage, and Terrorblade's high armor can reduce his damage significantly.
Juggernaut
* Heroes whose core item builds includes 
Monkey King Bar: Faceless Void, Windranger, Weaver, Juggernaut.
Lifestealer
* With Aghanim's Scepter upgraded Infest, Lifestealer can use it on enemy heroes to attack them and disarm them from inside, even if they are spell immune, which can give him the edge over the heroes he's weak against like Ursa, Phantom Assassin, Terrorblade or Troll Warlord.
Juggernaut
* Illusion-based heroes are effective against Omnislash and Juggernaut's single-targeted damage: Naga Siren, Chaos Knight, Terrorblade,Phantom Lancer.
Lifestealer
* Heroes with illusions: Chaos Knight, Naga Siren, Phantom Lancer, Terrorblade
Juggernaut
* Blade Fury offers good AoE damage to clear illusions and can hurt the real Naga Siren as well if she chooses to blend in the illusions. Diffusal Blade does nothing to Juggernaut either when he uses Blade Fury.
* Aghanim's Shard upgraded Blade Fury along with Lv 20 DPS talent will shred all illusions almost instantly, especially when combined with 
Mjollnir, a common item for Juggernaut.
Juggernaut
* Juggernaut can trigger Proximity Mines while in Blade Fury, and can walk away from a initiation with Blast Off if Blade Fury is activated before the silence.
* Juggernaut ignores Reactive Tazer when he uses Omnislash, whether Techies used it to protect an ally or themselves.
Lifestealer
* Rage protects Lifestealer from all of Techies's abilities. 
Reactive Tazer's disarm will also not work on Lifestealer under Rage.
* Rage can also be used to trigger Techies's 
Proximity Mines safely.
Additional:
* Lifestealer's Rage lets him clear Proximity Mines without taking damage, and allows him to hit heroes whom Techies has used Reactive Tazer on.
Juggernaut
* Blade Fury, similar to Rage, grants immunity to Invoker's spells and can dispel some debuffs as well.
* Omnislash renders Juggernaut invulnerable to Invoker's spells and can easily take Invoker down.
Additional:
* Juggernaut's instant spell immunity from Blade Fury. helps him dodge Invoker's combos. He can dispel the disables from 
Cold Snap and 
Deafening Blast and dodge the damage from 
Chaos Meteor, as well as walk through 
Ice Wall.
* Juggernaut's high DPS allows him to kill split pushing 
Forge Spirit(s) effortlessly, and his high armor prevents them from being a threat to him.
* However, Invoker can hit Juggernaut with 
Sun Strike through Blade Fury, making the 
Tornado and Sun Strike combo a threat if he does not dodge Tornado.
Lifestealer
* Rage grants immunity from Invoker's spells and can dispel most of the disables such as the armor loss from Forge Spirit and the constant stuns of Cold Snap.
Additional:
* Rage protects Lifestealer from all of Invoker's spells (except for Sun Strike).
Juggernaut
* Blade Fury and Omnislash allows Juggernaut to avoid Gyrocopter's area attacks entirely.
Lifestealer
* Rage ignores all of Gyrocopter's magical attacks.
* Feast helps Lifestealer out-damage Gyrocopter at close range.
Juggernaut
* Juggernaut's Healing Ward can help save allied supports when Spectre attempts a 
Haunt kill.
* Juggernaut has a stronger push potential than Spectre, enabling him to end the game early before Spectre can come online.
* Spectre is often paired with two supports that are often weak against Juggernaut.
* Juggernaut also tends to build a Manta Style, which can prevent 
Desolate from taking effect.
* Juggernaut is invulnerable against 
Dispersion while using Omnislash.
Lifestealer
* Feast deals damage and heals lifestealer based on the target max health. Because Spectre often emphasises on building stat items to increase her HP pool, lifestealer can deal a lot of damage to her and heal himself at the same time.
* 
Ghoul Frenzy slows target, which is bad for Spectre if she does not have 
Spectral Dagger ready.
* Spectre cannot response to infest if lifestealer choose to stay inside his high mobility allies to approach the backline. Rage's bonus movement speed and spell immunity make it even more frustrating.
Juggernaut
* Blade Fury protects Juggernaut from all of Tiny's magic burst damage.
Lifestealer
* Feast will deal a enormous amount of damage because of Tiny's huge health pool.
* Rage protects Lifestealer from Tiny's magical burst damage.
Juggernaut
* Blade Fury makes Juggernaut immune to the damage from Life Break and Burning Spears.
* It can be instantly activated the second Juggernaut sees Huskar flying towards him with Life Break, blocking all damage.
* Healing Ward effectively negates any damage-over-time from Burning Spears.
* Huskar has no defense against Omnislash and takes heavy damage due to his low armor.
Lifestealer
* Rage renders Lifestealer immune to the damage from Burning Spears.
* Feast makes Lifestealer one of few heroes that can outlast Huskar in a one-on-one fight.
Juggernaut
* Blade Fury makes Juggernaut immune to all Nyx's abilities, except 
Vendetta.
* Omnislash. and Swiftslash can burst Nyx down, ignoring 
Spiked Carapace. However, Vendetta can be used to escape, canceling Omnislash/Swiftslash.
Additional:
* Juggernaut's entire skillset greatly counters Nyx Assassin's Spiked Carapace, his most important ability.
* Blade Fury allows Juggernaut to freely attack Nyx Assassin, and deal heavy damage to Nyx Assassin. Nyx Assassin cannot counter Blade Fury with Spiked Carapace because Blade Fury gives Juggernaut spell immunity. And besides Vendetta, Nyx Assassin has no other way of dealing damage to Juggernaut while he is spell immune.
* Healing Ward allows Juggernaut to recover himself and his allies from Nyx Assassin's damage output.
* Omnislash and Swiftslash from Aghanim's Scepter can quickly finish off Nyx Assassin. And just like Blade Fury, Nyx Assassin cannot counter neither Omnislash and Swiftslash from Aghanim's Scepter with Spiked Carapace because both abilities render Juggernaut invulnerable. And if Nyx Assassin has no Vendetta available to use for escaping, both abilities will kill him very quickly before he can do anything.
* Overall, any attempt for Nyx Assassin to gank and kill Juggernaut will hurt Nyx Assassin more than Juggernaut.
Lifestealer
* Rage allows Lifestealer to freely attack Nyx Assassin and hunt him down if Vendetta is on cooldown. Nyx Assassin cannot counter Rage with Spiked Carapace because Rage gives Lifestealer spell immunity. And besides Vendetta, Nyx Assassin has no other way of dealing damage to Lifestealer while he is spell immune.
* Open Wounds from Aghanim's Shard allows Lifestealer to severely slow down Nyx Assassin while also allowing his team to recover themselves while attacking Nyx Assassin. Open Wounds can also fester and spread if Nyx Assassin takes enough damage that will trigger the spread while he is affected with Open Wounds.
* Infest combined with an ancient creep makes Nyx Assassin an easy target to surprise with 
Dust of Appearance or a 
Gem of True Sight. Aghanim's Scepter upgraded Infest can also allow Lifestealer to infest, disarm and freely attack Nyx Assassin from within. and Nyx Assassin cannot counter this with Spiked Carapace because Lifestealer is invulnerable while attacking the infested enemy hero from within.
* Overall, any attempt for Nyx Assassin to gank and kill Lifestealer will hurt Nyx Assassin more than Lifestealer.
Additional:
* Like with Juggernaut's Blade Fury, Rage allows Lifestealer to freely attack Nyx Assassin and hunt him down if Vendetta is on cooldown. Nyx Assassin cannot counter Rage with Spiked Carapace because Rage gives Lifestealer spell immunity. And besides Vendetta, Nyx Assassin has no other way of dealing damage to Lifestealer while he is spell immune.
* Open Wounds from Aghanim's Shard allows Lifestealer to severely slow down Nyx Assassin while also allowing his team to recover themselves while attacking Nyx Assassin. Open Wounds can also fester and spread if Nyx Assassin takes enough damage that will trigger the spread while he is affected with Open Wounds.
* Infest combined with an ancient creep makes Nyx Assassin an easy target to surprise with Dust of Appearance or a Gem of True Sight. And similarly to Juggernaut's Omnislash and Swiftslash from Aghanim's Scepter, Aghanim's Scepter upgraded Infest can also allow Lifestealer to infest, disarm and freely attack Nyx Assassin from within. And Nyx Assassin cannot counter this with Spiked Carapace because Lifestealer is invulnerable while attacking the infested enemy hero from within.
* Like with Juggernaut, any attempt for Nyx Assassin to gank and kill Lifestealer will hurt Nyx Assassin more than Lifestealer.
Juggernaut
* Blade Fury dispels most of Dark Willow's abilities, allowing Juggernaut to pass through Bramble Maze and cancel out Cursed Crown before the stun occurs.
* However, Dark Willow can tank Omnislash with 
Shadow Realm. As she is a valid target, but invulnerable to right clicks.
Additional:
* None of Dark Willow's spells pierce Spell Immunity, making Blade Fury a good counter against her. Additionally, it dispels 
Cursed Crown and 
Bramble Maze.
* Dark Willow is generally fragile, which results in Omnislash being devastating against her.
* However, if Shadow Realm is activated during Omnislash, then the attack damage is negated (though Omnislash can still jump to other enemies).
Lifestealer
* Rage protects and dispels all of Dark Willow's abilities.
Additional:
* Rage protects Lifestealer from all of Dark Willow's abilities.
Juggernaut
* Blade Fury allows Juggernaut to simply move out of Kinetic Field and to dodge Glimpse.
Lifestealer
* Rage can be used to escape from a Glimpse and to move out of Kinetic Field.
* Infest allows Lifestealer to dodge Glimpse.
Juggernaut
* Blade Fury negates Kunkka's X Marks the Spot.
* Kunkka has no way to dodge Omnislash.
* Kunkka has no way to hit Healing Ward directly in battle, and it mitigates Ghostship and Tidebringer's damage.
Lifestealer
* Rage negates Kunkka's X Marks the Spot.
* As a strength hero with high strength gain and very little armor, as well as low agility gain, Kunkka is vulnerable to Lifestealer's Feast and Open Wounds.
Juggernaut
* Juggernaut is invulnerable while using Omnislash, meaning that neither 
Blade Mail or Power Cogs will save Clockwerk, this is especially common during the early laning phase.
* Blade Fury will also ignore any damage dealt by Battery Assault, as well as dealing heavy damage. As long as Juggernaut has mana to cast it.
* Overall, any attempt for Clockwerk to trap Juggernaut with Power Cogs will hurt him a lot more than the other way around.
Lifestealer
* With Feast and Rage, Lifestealer is nearly impossible for Clockwerk to bring down, and is the last hero Clockwerk wants to be trapped with in Power Cogs.
Juggernaut
* None of Zeus's abilities can damage a Juggernaut in Blade Fury.
* Zeus's short attack range makes it difficult for him to target a well-placed Healing Ward. His frequent use of 
Arc Lightning will have almost no effect on allies being healed by Juggernaut.
* Zeus has no way to defend himself, even if Juggernaut cannot use Blade Fury. He can be easily taken out if cornered, sometimes even without Omnislash.
Additional:
* Blade Fury negates all magical damage from Zeus.
* Omnislash can easily take down Zeus. However, be aware that most players will get a 
Eul's Scepter of Divinity or a 
Ghost Scepter against Juggernaut.
Lifestealer
* Heroes who have most or all their abilities (damage or disable) unable to pierce spell immunity: Keeper of the Light, 
Lina, 
Lion, 
Zeus.
Additional:
* Rage is very useful against Zeus, as it negates magic damage and provides spell immunity. In addition, the increased attack speed can tear Zeus apart in combination with Open Wounds.
* Lifestealer can avoid Thundergod's Wrath with Infest.
Juggernaut
* Heroes with good mobility to avoid Jakiro's abilities and with good chase to punish Jakiro from pushing a tower: Bloodseeker, Ember Spirit, Juggernaut, Phantom Assassin, Weaver.
Lifestealer
* Rage grants Lifestealer immunity to all of Jakiro's spells. Note: magic resistance will not dispel the attack speed slow effects from Dual Breath and Liquid Fire.
Juggernaut
* Juggernaut's high attack speed lets him destroy a 
Supernova easily. He can even attack a Supernova during Blade Fury with his regular attacks.
* Blade Fury protects Juggernaut from all of Phoenix's spells (except Supernova, which pierces spell immunity).
* Blade Fury can also dispel the attack speed slow from 
Fire Spirits and the movement speed slow from 
Icarus Dive.
* Phoenix's Icarus Dive will not protect it from Omnislash unless it dives into creeps, and Phoenix's low armor makes for an easy kill.
Lifestealer
* Heroes with spell immunity-granting spells will render Phoenix useless against them, as Phoenix has almost no spell immunity-piercing ability, other than the stun at the end of Supernova: Lifestealer, Juggernaut.
Juggernaut
* Heroes with spell immunity: Juggernaut, Pangolier, 
Huskar.
Lifestealer
* Leshrac's high magic damage is ignored by Rage.
* Lifestealer can get in Leshrac's face with Rage and mitigate any other damage taken by Leshrac with Open Wounds.
Lifestealer
* Heroes who rely on physical damage output to be effective will fare badly against Muerta's 
Pierce the Veil: Phantom Assassin, Terrorblade, Drow Ranger, Lifestealer, Anti-Mage, 
Alchemist, Lycan, Clinkz, Sniper.
Juggernaut
* Blade Fury grants spell immunity and also allows him to deal massive magical damage, both of which are Muerta's general counters.
* However, Juggernaut has no way of hurting Muerta through Pierce the Veil outside of Blade Fury, Juggernaut's only source of dealing magical damage. And unlike other abilities and items that turn the user ethereal, Pierce the Veil cannot be dispelled at all, making Nullifier useless for Juggernaut. This forces Juggernaut to buy 
Revenant's Brooch.
Lifestealer
* Lifestealer can activate Rage to become spell immune, making Pierce the Veil do no damage and preventing Dead Shot from fearing or doing damage.
* Lifestealer can use Infest to avoid Muerta's Gunslinger shots, Dead Shot's fear and surprise Muerta. Aghanim's Scepter upgraded Infest can be used to disarm Muerta while she has Pierce the Veil and even through Black King Bar.
* However, Lifestealer has no way of hurting Muerta through Pierce the Veil outside of Infest, Lifestealer's only source of dealing magical damage. This forces Lifestealer to buy Revenant's Brooch.
Juggernaut
* Keeper of the Light's 
Blinding Light makes Juggernaut miss his attacks. However, it can be dispelled easily with Blade Fury.
Juggernaut
* Juggernaut's Healing Ward keeps his team healthy even when pushing against Keeper of the Light's 
Illuminate.
* Blade Fury can dispel Blinding Light, as well as dodge an incoming Illuminate. Juggernaut can attack towers during Blade Fury, so he can dodge an Illuminate without having to stop pushing.
* Should Keeper of the Light obtain 
Will-o-Wisp through purchasing an Aghanim's Scepter, Juggernaut can make quick work of Ignis Fatuus without being interrupted by its pull.
* Keeper of the Light has low health, low armor, and no natural defense against Blade Fury.
Additional:
* Blade Fury allows him to be immune to all of Ezalor's abilities.
* Healing Ward heals his entire team, mitigating Ezalor's weak magical burst damage.
Lifestealer
* Rage allows him to be immune to all of Ezalor's abilities. Also, the increased movement speed combined with the slow from Ghoul Frenzy and the squishy nature of Ezalor allows Lifestealer to take him down very quickly.
Juggernaut
* Juggernaut and Lifestealer have abilities (Blade Fury and Rage respectively) that prevent Crystal Maiden from using her spells on them in the early game, before Black King Bar and other magical reduction is even an issue.
Lifestealer
* Juggernaut and Lifestealer have abilities (Blade Fury and Rage respectively) that prevent Crystal Maiden from using her spells on them in the early game, before Black King Bar and other magical reduction is even an issue.
Additional:
* Crystal Maiden is an ideal target for Lifestealer due to her poor mobility and low health pool. Lifestealer can usually catch up to her simply by casting Rage, as none of her abilities pierce through magic immunity. 
Freezing Field can potentially make her even more vulnerable to Lifestealer while under Rage as she is even more immobile while channeling it.
* Lifestealer commonly buys Abyssal Blade, which allows him to cancel Freezing Field, even if Crystal Maiden is spell immune.
* Alternatively, Aghanim's Scepter upgraded Infest combined with Abyssal Blade and with items that provide attack speed which Lifestealer commonly buys allow him to to cancel Freezing Field from within the Crystal Maiden.
Juggernaut
* Heroes with spell immunity unless Lina chooses to play Carry role like Lifestealer with Rage and Juggernaut with Blade Fury.
Lifestealer
* Heroes who have most or all their abilities (damage or disable) unable to pierce spell immunity: Keeper of the Light, Lina, Lion, Zeus.
Additional:
* Rage protects Lifestealer from all of Lina's abilities. However, Lina can paritally counter this if played as Carry, a common role for Lina.
* Open Wounds from Aghanim's Shard can severely slow down Lina and allow Lifestealer and his allies to recover themselves by attacking her.
* Aghanim's Scepter upgraded Infest can be used to disarm Lina even if she is spell immune, rendering her unable to maximize the effect of her 
Fiery Soul and force her to use her abilities more often than intended. And Lina's only way to counter this is with 
Linken's Sphere
Juggernaut
* Juggernaut with Blade Fury
* 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.
Lifestealer
* Lifestealer with Rage and Infest
* 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.
Lifestealer
* Rage gives Lifestealer spell immunity, Chen and his converted creeps have little to no ways of fighting back against Lifestealer whenever he activates it.
* Feast allows Lifestealer to recover himself by damaging Chen's creeps.
* Chen has no escape mechanisms, so he will often be unable to escape from slows applied with Ghoul Frenzy.
* Open Wounds from Aghanim's Shard can severely slow down Chen, and allow Lifestealer and his team to heal themselves by attacking Chen. Open Wounds can also fester and spread if Chen takes enough damage that will trigger the spread while he is affected with Open Wounds.
* Infest allows Lifestealer to infest into one of Chen's converted creeps and take control of it, which allows Lifestealer to either escape from Chen or surprise him. Aghanim's Scepter upgraded Infest can disarm Chen and allow Lifestealer to attack Chen from within, even if Chen is spell immune.
Juggernaut
* Blade Fury makes Juggernaut immune against all of Snapfire's spells and allows him to get closer.
* A well-timed Omnislash allows Juggernaut to dodge Snapfire's spells, and she has no way to deal with it.
Lifestealer
* Feast deals damage and heals Lifestealer based on the target's maximum HP, which is greatly effective against naturally high HP heroes such as Doom.
* Rage allows Lifestealer to become spell immune to negate the magical damage of Infernal Blade and Scorched Earth.
* Doom has no effective means of escape from Open Wounds and Ghoul Frenzy. This is particularly devastating in the laning stage, where Doom may have to play a much more passive, conservative play style as a result.
Lifestealer
* Rage can protect Lifestealer from most of the Silencer's abilities with the exception of 
Global Silence, as it will still silence if cast while the target is magic immune. However, it will not work if Lifestealer is infesting a unit.
* Silencer is vulnerable to Open Wounds due to his lack of an innate escape.
* Against a carry Silencer, Aghanim's Scepter upgraded Infest can disarm him and allow Lifestealer to attack Silencer from within, even if Silencer is spell immune.
Additional:
* Rage can protect Lifestealer from most of the Silencer's abilities with the exception of Global Silence.
* If Lifestealer can Infest himself on any unit, he can literally avoid being affected by Global Silence.
* Against a carry Silencer, Aghanim's Scepter upgraded Infest can disarm him and allow Lifestealer to attack Silencer from within, even if Silencer is spell immune.
* Open Wounds from Aghanim's Shard can severely slow down Silencer, and allow Lifestealer and his team to heal themselves by attacking Silencer.
Lifestealer
* Being a strength hero with a high strength gain means Feast can give her a hard time,especially later in the game.
* However,
Starbreaker's physical damage can control him in the laning phase.
Juggernaut
* Kraken Shell provides no protection against Omnislash or Swiftslash.
* If timed correctly, Omnislash, Swiftslash and Blade Fury are all capable of dodging Ravage, giving Juggernaut several tools to render your strongest ability moot.
* Blade Fury is an effective way to harass Tidehunter in the laning stage as Tidehunter has no means of getting Juggernaut away from him. Healing Ward also greatly minimizes Tidehunter's ability to harass Juggernaut.
* 
Blade Dance minimizes the effectiveness of Anchor Smash's damage reduction.
Lifestealer
* Feast is good against high health strength heroes such as Alchemist.
* Rage allows Lifestealer to not be targetable by Unstable Concoction, possibly making Alchemist stun himself.
Lifestealer
* Lifestealer's Rage makes him immune to all of Ogre's magical debuffs and also dispels them.
* Ogre's high health pool makes him an ideal target for Feast.
Additional:
* Ogre Magi has nothing against Rage and his high health pool amplifies Feast.
Lifestealer
* Rage ignores all of Viper's magical damage, although 
Viper Strike can pierce spell immunity and slows him down.
* Feast and Open Wounds from Aghanim's Shard can be combined to heal through Viper's physical damage.
* Aghanim's Scepter upgraded Infest can be used to disarm Viper, preventing him from using 
Poison Attack on Lifestealer's allies.
Lifestealer
* Rage prevents Earthshaker from damaging and stunning Lifestealer.
* Feast is very effective against Earthshaker, because of him being a strength hero, allowing Lifestealer to heavily harass and kill him.
* Open Wounds prevents Earthshaker from escaping after he initiated.
* Infest gives Lifestealer an easy way to escape should he get caught out by Earthshaker. And against carry Earthshaker, Aghanim's Scepter upgraded Infest can be used to disarm Earthshaker and attack him from within, rendering him unable to attack with 
Enchant Totem.
Lifestealer
* Lifestealer's Rage renders him immune to all of Marci's disables and magic damage for a good duration.
* His passive Feast deals bonus damage based on the enemy's max health and heals for the same amount. As a tanky Strength hero, Marci's own strength will be her undoing as well.
Lifestealer
* Feast is an effective tool against Centaur Warrunner, who generally has high health and low armor, and compensates the reflected damage of Retaliate.
* If activated, Rage can protect Lifestealer from Hoof Stomp, Double Edge, and Stampede.
Additional:
* Centaur Warrunner's active abilities cannot pierce magic immunity. 
Hoof Stomp's slow wind up can also be anticipated and negated with Rage.
* Lifestealer can offset 
Retaliate's damage return simply with Feast. Centaur's high strength gain and therefore big health pool makes him an ideal target to Feast on, especially in the late-game.
Lifestealer
* 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.
Juggernaut
* Wraithfire Blast is quite predictable, and players with good reflexes will disjoint it with Blade Fury.
* Omnislash with Diffusal Blade & Aghanim's Scepter can prevent Wraith King from reincarnating unless he has his Aghanim's Shard that removes the mana cost from Reincarnation.
Juggernaut
* Blade Fury makes Juggernaut immune to Elder Titan's stun, so there is a high chance he wont get caught in your ultimate although Earth Splitter pierces spell immunity.
Lifestealer
* Lifestealer's Rage makes him immune to all of Tinker's damage and debuffs.
* Lifestealer can infest a mobile ally (teams usually pick one against Tinker), which may ensure that Tinker will die if he is caught.
Additional:
* Rage will dispel Laser's blind and turns him spell immune for the duration so Tinker cannot damage him.
* Feast will quickly bring down Tinker due to being so fragile.
Lifestealer
* Heroes who have most or all their abilities (damage or disable) unable to pierce spell immunity: Keeper of the Light, Lina, Lion, Zeus.
Additional:
* Rage makes Lifestealer debuff immune and gives him magic resistance which can drastically reduce magical damage from Lion's abilities while also preventing Lion to do anything to him.
* Lion's lack of inner escape and defensive mechanisms increases Ghoul Frenzy effectiveness, since it applies slows upon attacking.
* Lifestealer's physical damage output is strong against Lion's low health and base armor
* Infest can be used to surprise unsuspecting Lion if he tries to take down alone enemy hero. Aghanim's Scepter upgraded Infest can be used to disarm Lion and attack him from inside, even if Lion is debuff immune with the Aghanim's Shard upgraded 
Mana Drain.
Lifestealer
* Heroes with burst damage of their own won't be afraid to go toe to toe with Void Spirit, like Ursa, Lifestealer, or 
Axe.
Juggernaut
* Skywrath's pitiful defences also make him easy meat to heroes with high burst like Juggernaut, Lion, or Phantom Assassin, the latter occasionally downing a support Skywrath in a single 
Stifling Dagger.
Juggernaut
* Heroes with stronger lane presence that can threaten to kill him: 
Batrider, Juggernaut, Ursa, Monkey King, 
Razor.
Juggernaut
* 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.
Juggernaut
* Heroes with spell immunity abilities won't be caught inside by Pit of Malice: Juggernaut, Lifestealer.
Lifestealer
* Heroes with spell immunity abilities won't be caught inside by Pit of Malice: Juggernaut, Lifestealer.
Lifestealer
* Heroes with good escape mechanisms are a nuisance to deal with in the early phase of the game: Slark, Lifestealer, Morphling
Lifestealer
* Heroes who can delivers a big chunk of damage in few hits will find themselves struggle against Templar Assassin's Refraction: Sven, Phantom Assassin, Ursa, Wraith King, Lifestealer
Juggernaut
* Blade Fury's damage over time dispels 
Refraction almost instantly.
* Juggernaut's high armor allows him to survive for long enough to remove Refraction and threaten her with Omnislash as long as he or his team carries detection.
* Templar Assassin's short attack range makes it difficult for her to target a well-placed Healing Ward. She cannot splash onto it with 
Psi Blades.
Juggernaut
* Heroes who rely on physical damage are easily negated by Ghost Shroud: Phantom Assassin, Wraith King, Juggernaut.
Juggernaut
* Blade Fury blocks the damage done by 
Death Pulse and 
Reaper's Scythe. Additionally, 
Ghost Shroud decreases Necrophos's magic resistance, making him take more damage from Blade Fury.
Juggernaut
* Heroes who rely on fast attack speed will also trigger Counter Helix frequently: Faceless Void, Troll Warlord, Anti-Mage, Juggernaut, 
Arc Warden, Morphling
Additional:
* 
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 
Counter Helix.
* Axe is a common Blade Mail and Blink Dagger carrier making him a very big potential threat before Juggernaut get his items.
Lifestealer
* Feast makes it impossible to for Lifestealer to be culled with 
Culling Blade and also deals high damage to Axe due to his naturally high health.
* However, Berserker's Call and Counter Helix can pierce through the Rage, and if Axe has allies with him against Lifestealer, Lifestealer may go down very quickly.
Juggernaut
* 
Astral Imprisonment allows Outworld Destroyer to save himself or his teamates during Omnislash.
* Juggernaut's low mana from his low intelligence gain means that he'll take a lot of damage from 
Sanity's Eclipse.
Juggernaut
* Heroes with built-in spell immunity can become immune to all of Outworld Destroyer's spells: Lifestealer's Rage and Juggernaut's Blade Fury.
Lifestealer
* Heroes with built-in spell immunity can become immune to all of Outworld Destroyer's spells: Lifestealer's Rage and Juggernaut's Blade Fury.
Lifestealer
* Since 
Untouchable pierces Spell Immunity, Lifestealer cannot burst her down even with Rage; meaning she can heal herself back to full HP.
Juggernaut
* Blade Fury dispels the slow from Enchant, and can burst Enchantress down during the laning stage.
* Omnislash and Swiftslash's physical damage burst ignore untouchable.
* Silver Edge is a common item for Juggernaut for dealing with Untouchable.
Additional:
* Blade Fury dispels the slow from 
Enchant, spell immunity and used to burst her down during the early laning stage.
* Omnislash and Swiftslash's physical damage burst ignore Untouchable.
* Silver Edge is an ideal item for Juggernaut to deal with Untouchable, making her vulnerable to melee attacks.
Juggernaut
* 
Bulwark mitigates Omnislash which deals physical damage, severely reducing its damage.
* Omnislash switch to opposite direction with each slash, so Mars can easily reduce most of its damage.
* However because {Ability ID:Blade Fury|Juggernaut} gives spell immunity Juggernaut can easily escape from {Ability ID:Arena Of Blood|Mars}.
Additional:
* Juggernaut deals mostly physical damage, which is easily mitigated with Bulwark.
* Juggernaut's Omnislash switches to opposite directions which each slash, so Mars can mitigate most of its damage since he only takes full damage from one direction: his back.
Lifestealer
* Rage, acting as a pseudo-Black King Bar, completely negates Mars' initiation if used in time.
* Feast does damage and heals based on max health, perfect against high-health strength heroes like Mars.
* Infest allows Lifestealer to potentially save allies from Mars' initiation with a quick burst of extra health.
Juggernaut
* Heroes with escaping and disjointing abilities can be good against Juggernaut:Anti-Mage Riki, Queen of Pain, Puck, Storm Spirit, Ember Spirit, Slark etc.
Lifestealer
* Melee heroes that get kited easily have hard times dealing with Puck without any lockdowns, as Puck is one of the most mobile heroes. Heroes like Sven, Lifestealer, Ursa and Alchemist may have problems to get to Puck without proper initiation items. They also lack reliable lockdowns, as their disables are easily avoidable for Puck, or are just a soft disable.
Juggernaut
* Heroes with spell immunity or pseudo-blinks which provide invulnerability: Lifestealer, Juggernaut, Omniknight, Huskar, and Tusk have spells which allow them to easily escape Dream Coil.
Lifestealer
* Heroes with spell immunity or pseudo-blinks which provide invulnerability: Lifestealer, Juggernaut, Omniknight, Huskar, and Tusk have spells which allow them to easily escape Dream Coil.
Juggernaut
* Juggernaut deals most of his damage in the melee range and has no gap-closer. Sniper can easily harrass Juggernaut from afar with his long-ranged attacks and {Ability ID:Headshot|Sniper|16px} procs.Should Juggernaut decide to advance,Sniper has enough time to react and back off.
* Sniper's long range attack can destroy Healing Ward from a safe range, preventing any healing done to Juggernaut and/or his teammates.
* However, if Sniper is badly positioned, Juggernaut can easily terminate him.
Lifestealer
* Lifestealer can close the distance to Sniper by using Infest on a fast or durable creep to tank Sniper's damage.
* Open Wounds and Ghoul Frenzy will reduce Sniper's mobility heavily, and Rage's movement speed bonus helps in closing the gap to Sniper. It also protects him from Assassinate and Shrapnel.
* Infest can dodge an incoming Assassinate or to surprise Sniper during ganks. Aghanim's Scepter upgraded Infest can also allow Lifestealer to disarm Sniper and attack him from inside.
Lifestealer
* Heroes with high physical damage can damage Lifestealer more than he can heal: Bristleback, Clinkz, Luna,Shadow Fiend, Slardar, Terrorblade
Juggernaut
* Illusion heroes like the aforementioned Phantom Lancer or Naga Siren, or heroes that tend to buy Manta Style, like Luna or Juggernaut, will give Slardar a hard time, as his damage is single-targeted.
Lifestealer
* Although Lifestealer can avoid Eclipse with Rage and Infest, Luna's physical damage can be enough to deal with him.
* Manta Style is a common pick on Luna, which can help her dispel slows from Ghoul Frenzy and Open Wounds. In addition, Lifestealer is not good against illusions created by Manta Style.
Additional:
* Although Lifestealer can avoid Eclipse with Rage and Infest, Luna's physical damage from 
Moon Glaives and 
Lunar Blessing can be enough to deal with him.
* Manta Style is a common pick on Luna, which can help her dispel slows from Ghoul Frenzy and Open Wounds. In addition, Lifestealer is not good against illusions created by Manta Style.
* Even though Aghanim's Scepter upgraded Infest can disarm Luna and allow Lifestealer to attack her from inside even if she is spell immune, Luna can easily counter this with Linken's Sphere, which is a common item on Luna.
Juggernaut
* Because of her low range, Luna cannot easily destroy Healing Ward.
* Both Blade Fury and Omnislash are direct counters to Eclipse, offering Juggernaut spell immunity and invulnerabilty. Therefore, Luna will need assistance in taking down Juggernaut as going solo will not be successful.
* For the same reasons, Juggernaut makes a very powerful ally for Luna when they are in the same team.
Juggernaut
* 
Meat Hook can hit and displace Juggernaut during his Blade Fury.
* 
Dismember pierces Juggernaut's spell immunity from Blade Fury.
Lifestealer
* The lifesteal of Feast scales accordingly to the max health of its target, which is effective against Pudge due to his high health and further health granted by stacks of Flesh Heap.
* Lifestealer can activate Rage to be spell immune, making Rot deal no damage.
* Pudge's plentiful health makes him an ideal target for Lifestealer's Aghanim's Shard ability, Open Wounds.
Juggernaut
* 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.
Lifestealer
* Heroes that can easily bypass Io's allies to get to Io: Riki, Tusk, Clinkz, Sniper, Slark, Phantom Assassin, 
Void Spirit, Storm Spirit, Ember Spirit, 
Earth Spirit, Spirit Breaker, Lifestealer.
Lifestealer
* Lifestealer, at even farm levels, will often fall against other man-fighting non-Strength cores like Ursa, Phantom Assassin or Troll Warlord as he cannot truly rely on sustain from Feast.
Additional:
* Rage does absolutely nothing against Phantom Strike with items.
* Feast and Ghoul Frenzy are very difficult to utilise thanks to Blur.
* Lifestealer generally wants to buy items that make him hard to kill, not an Monkey King Bar which only offers damage.
Lifestealer
* With Aghanim's Scepter upgraded Infest, Lifestealer can use it on enemy heroes to attack them and disarm them from inside, even if they are spell immune, which can give him the edge over the heroes he's weak against like Ursa, Phantom Assassin, Terrorblade or Troll Warlord.
Lifestealer
* Heroes that rely on slows to get kills: Lifestealer, Night Stalker, Ursa, Phantom Assassin, Terrorblade.
Lifestealer
* Lifestealer's Rage negates Sand King's spells which do magical damage.
Lifestealer
* Heroes with summons: Lycan, Broodmother, Visage, Nature's Prophet, Warlock.
Lifestealer
* Heroes with magic immune abilities can negate most of Visage's attacks like Pangolier and Lifestealer.
Juggernaut
* {Ability ID:Windrun|Windranger|16px} negates the damage from {Ability ID:Omnislash|Juggernaut|16px}.
* {Ability ID:Windrun|Windranger|16px} gives Windranger enough movement speed to get out of {Ability ID:Blade fury|Juggernaut|16px} range.
* {Ability ID:Focus fire|Windranger|16px} goes through {Ability ID:Blade Fury|juggernaut|16px}.
Lifestealer
* Windranger's highly mobile playstyle allows her to easily control Lifestealer from a distance, as he has no disables on his own.
Windrun not only provides her with bonus move speed, but evasion as well, undoing Lifestealer's ability to attack her. In combination with 
Focus Fire, Windranger can easily dispose of Lifestealer without him being able to reach her.
