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.
Lina
* 
Time Walk will easily backtrack Lina's burst damage (especially Laguna Blade) if not timed correctly.
* During 
Chronosphere, squishy heroes like Lina will be main target of Faceless Void in his ultimate.
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.
Lina
* 
Dragon Slave is easy to steal, and provides Rubick with a useful nuke.
* 
Light Strike Array serves as a cheap nuke as well as a crowd control ability.
* Rubick uses the fixed 0.15 second cast time when casting Light Strike Array, much faster than 
Lina herself.
* Rubick can gurantee a stun by throwing the victim into the area with Telekinesis, extending the overall lockdown duration.
* 
Laguna Blade is an awesome ultimate that gives huge burst damage.
* 
Arcane Supremacy (combined with Level 25 talent +40% Spell Amp For Stolen Spells, as of 7.31c) increases its damage before reduction to a whopping 660/882/1134(830/1162/1494) (and even more so with 
Aghanim's Scepter), without considering spell amplification from items.
* Laguna Blade is an intelligence hero with no regen ability, and casting Laguna Blade back to Lina can result in her unexpected sudden death, or severly hinder her presence in the rest of teamfight. Nevertheless, the skill can also be cast on other squishy heroes or help bursting down enemy carries.
* Light Strike Array and Laguna Blade has a short cast range, and Rubick can extend its range thanks to Arcane Supremacy.
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.
Lina
* Ember Spirit absorbs quite a large amount of magical damage with its 
Flame Guard, and in addition dodges the abilities of Dragon Slave and Light Strike Array with its 
Sleight of Fist
Additional:
* Ember Spirit absorbs quite a large amount of magical damage with its Flame Guard, and in addition dodges the abilities of Dragon Slave and Light Strike Array with its Sleight of Fist.
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.
Lina
* Sven has a high health pool and is a natural 
Black King Bar holder and is very hard to kill for Lina.
* Sven also has high physical damage, making it easy for him to burst her down.
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.
Lina
* Nether Ward will be problematic for heavy nukers and spammers like 
Skywrath Mage, Lina, 
Lion and 
Invoker, but Pugna must not use Decrepify defensively against them as he will be helping them out more than anything.
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.
Lina
* 
Blink allows Anti-Mage to get on top of Lina and deal damage with his 
Mana Break.
* 
Counterspell makes Anti-Mage tanky against Lina's heavy magic damage. It can also be used block and reflect Laguna Blade.
* 
Mana Void is very hazardous for Lina, who has a high mana pool and quickly depletes it during fights.
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.
Lina
* 
Viper Strike prevents buildup of Fiery Soul stacks.
* 
Corrosive Skin provides magic resistance against Lina's spells. However, Lina can counter this with 
Silver Edge, a common item on Lina.
* 
Poison Attack and Viper Strike can burn away Lina's small health pool.
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.
Lina
* 
Arcane Curse makes it too difficult Lina from using her abilities, preventing her from building up Fiery Soul stacks without causing harm to herself.
* 
Last Word and 
Global Silence are great against Lina for the same reason, as well as interrupting her combos and preventing her from casting spells.
Juggernaut
* Drow Ranger can use Gust to push back Juggernaut before he can get in range to use Omnislash or Blade Fury.
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.
Lina
* 
Dark Pact can be cast during the cast animation of Light Strike Array and dispel its stun.
* 
Pounce allows Slark to close the gap to Lina.
* Shadow Dance prevents Lina from killing Slark with her Laguna Blade when his HP gets low.
Lina
* Heroes with heavy magical nukes will take advantage of Slark's poor HP or force him to use Shadow Dance early: Lina, Lion, 
Zeus
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.
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.
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.
Lina
* Puck can dodge Lina's Dragon Slave and Light Strike Array with his 
Phase Shift skill, which helps him avoid combining these abilities with Laguna Blade and avoid burst damage from Lina.
* Puck forbids Lina to use her abilities with the 
Waning Rift ability, which will help her teammates survive and even give them the opportunity to kill her.
Additional:
* Puck can dodge Lina's Dragon Slave and Light Strike Array with Phase Shift. A good Puck player can even dodge Laguna Blade, as it has an invisible projectile, therefore avoiding all the burst damage from Lina.
* Puck forbids Lina to use her abilities with Waning Rift, which will help Puck's teammates survive and even give them the opportunity to kill her.
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.
Juggernaut
* Illusion-based heroes are effective against Omnislash and Juggernaut's single-targeted damage: 
Naga Siren, 
Chaos Knight, 
Terrorblade,
Phantom Lancer.
Lina
* 
Doppelganger can be used to easily dodge Light Strike Array if timed correctly.
* While Lina can clear Phantom Lancer's illusions with her abilities, Phantom Lancer can quickly deplete Lina's mana pool with his illusions and deal massive damage from it simultaneously since Phantom Lancer is a natural 
Diffusal Blade carrier.
Lina
* Heroes with summons and illusions can find themselves easily bested by Lina, like 
Broodmother, 
Nature's Prophet, 
Chen, Terrorblade, Naga Siren, 
Visage, 
Wraith King, 
Lycan, Phantom Lancer, 
Shadow Shaman.
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 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.
Lina
* 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
Lina
* Marci can be effective against vulnerable squishy heroes that cannot deal with heroes that jump onto them - 
Sniper, 
Drow Ranger, Lina, Rubick, etc.
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.
Lina
* Squishy heroes (Io, 
Crystal Maiden, Lina...), as Earth Spirit can deal tons of damage with Magnetize.
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.
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
* 
Meat Hook can hit and displace Juggernaut during his Blade Fury.
* 
Dismember pierces Juggernaut's spell immunity from Blade Fury.
Lina
* Heroes with abilities that can pull Lina out of position can easily bring her to their team mates, like 
Batrider with 
Flaming Lasso, 
Pudge with Meat Hook and 
Vengeful Spirit with 
Nether Swap.
Lina
* Pudge has low armor and mobility, making him suspectible to her physical attacks (if Lina is the carry).
* Because Dismember is a channeled ability, it can be canceled through Light Strike Array within a distance.
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.
Lina
* Storm Spirit can quickly close the distance with Lina using 
Ball Lightning. In addition, Ball Lightning can be used as a way to dodge the abilities of Dragon Slave and Light Strike Array
Additional:
* Storm Spirit can quickly close the distance with Lina using Ball Lightning. In addition, Ball Lightning can be used as a way to dodge the abilities of Dragon Slave and Light Strike Array
Lina
* Lina can win on a line against Storm Spirit because of the range of her abilities and attacks, and Storm Spirit will be forced to survive on such a line, not farm
Juggernaut
* Heroes with high armor and/or durability can handle Juggernaut's ultimate, such as Sven and Dragon Knight.
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.
Lina
* Heroes with abilities that can pull Lina out of position can easily bring her to their team mates, like Batrider with Flaming Lasso, Pudge with Meat Hook and Vengeful Spirit with Nether Swap.
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.
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.
Lina
* Heroes who can clear the waves of Enigma's Eidolons: Lina, 
Luna, 
Dawnbreaker, 
Jakiro, Shadow Shaman, 
Death Prophet, Keeper of the Light, Invoker, 
Leshrac, Puck.
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}.
Lina
* Since Windranger is bad against magical damage, heroes with continuous magical damage or magical nukes can blast her: Zeus, 
Tinker, Leshrac, 
Viper, Skywrath Mage, Lion, Lina, 
Venomancer.
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.
Lina
* Heroes with summons and illusions can find themselves easily bested by Lina, like Broodmother, Nature's Prophet, Chen, Terrorblade, Naga Siren, Visage, Wraith King, Lycan, Phantom Lancer, Shadow Shaman.
Additional:
* Lina can easily prevent Nature's Prophet's Teleportation escape attempts with Light Strike Array, and can clear Sprout's trees instantly.
* Lina's Dragon Slave and Light Strike Array can kill Nature's Prophet's Treants.
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.
Lina
* Both Lion's 
Finger of Death and Lina's Laguna Blade have a 0.25 second delay before the damage is dealt.
Lina
* Lina is a common 
Eul's Scepter of Divinity carrier which can waste some duration of Borrowed Time and following up with Laguna Blade if timed correctly.
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.
Lina
* Heroes with abilities that can pull Lina out of position can easily bring her to their team mates, like Batrider with Flaming Lasso, Pudge with Meat Hook and Vengeful Spirit with Nether Swap.
Lina
* Lina can burst Vengeful Spirit down, provided she can land Light Strike Array before Vengeful Spirit lands her Magic Missile.
* Laguna Blade deals massive damage, often being enough to kill a squishy Vengeful Spirit.
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.
Lina
* Enchantress has a very small health pool and cannot tank Lina's heavy magic burst.
* Untouchable is decently countered by Fiery Soul, exposing Enchantress's weakness to physical damage due to her low armor.
* Lina is decent at clearing creeps and can kill Enchantress's creeps quickly.
Additional:
* Enchantress has pitiful health, and cannot tank Lina's heavy magic damage.
* Untouchable is decently countered by Fiery Soul, exposing Enchantress's weakness to physical damage due to her low armor.
* Lina is decent at clearing creeps and can kill Enchantress' creeps quickly.
Juggernaut
* Blade Fury and Omnislash allows Juggernaut to avoid Gyrocopter's area attacks entirely.
Lina
* Laguna Blade ends Gyrocopter very quickly in the early to mid game.
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.
Lina
* Lina interrupts Huskar on the center line because of her attack range, she can constantly be at a long distance, punching Huskar with her hand, while Huskar needs a very close distance to use 
Burning Spear
Additional:
* Lina can interrupt Huskar on the center line because of her attack range, she can constantly be at a long distance, punching Huskar with her hand, while Huskar needs a very close distance to use Burning Spear.
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.
Lina
* Lina has very high magic burst damage to use against the low-health-pool Luna. Laguna Blade can also be upgraded with Laguna Blade damage is Pure and pierces Spell Immunity to bypass Black King Bar, making Lina even more of a threat. Luna however, can easily counter this problem with Linken's Sphere, which is a common item for her.
* For the same reasons, Lina makes a very powerful ally for Luna when they are in the same team.
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.
Lina
* Heroes with high physical and magical damage alike are a huge hazard for Muerta, as they can deal serious damage to her even if she has Pierce the Veil active: Luna, Lina, Tusk, Broodmother, 
Shadow Fiend, Ember Spirit, 
Gyrocopter, Vengeful Spirit, Arc Warden, 
Medusa, Shadow Shaman.
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.
Lina
* Being a hero with low health and abysmal mobility, Lina can nuke her down easily.
* Since Crystal Maiden's 
Freezing Field is a channeled ability, Lina can use her Light Strike Array to cancel it easily.
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.
Lina
* Any hero with high attack speed will be a threat to Phoenix when it initiates, as they can easily tear down a Supernova, perhaps even while debuffed by Fire Spirits: Juggernaut, 
Clinkz, Troll Warlord, 
Beastmaster, Lina.
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.
Lina
* Lina builds 
Shadow Blade (and upgrades it into a Silver Edge), which makes it hard for Ancient Apparition to land his abilities.
* Laguna Blade can kill Ancient Apparition easily due to his low health pool and lack of mobility.
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.
Lina
* Heroes with summons and illusions can find themselves easily bested by Lina, like Broodmother, Nature's Prophet, Chen, Terrorblade, Naga Siren, Visage, Wraith King, Lycan, Phantom Lancer, Shadow Shaman.
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.
Lina
* Ghost Shroud is not a good defensive ability against Lina as all of her abilities deal magical damage.
* Lina has a very long range of attack, which completely overlaps the range of Death Pulse and 
Heartstopper Aura.
* However, once Necrophos gets Aghanim's Shard, he will gain access to 
Death Seeker which will allow him to turn into a larger Death Pulse that can be used to close the gap on Lina and kill her if she is not careful.
Additional:
* Laguna Blade's damage as well as damage from all of Lina's abilities will be greatly amplified during Ghost Shroud.
Lina
* Light Strike Array catches Morphling while he jumps in from 
Waveform and also prevents Morphling from using his abilities.
* Laguna Blade can kill Morphling quickly before he shifts into 
Attribute Shift (Strength Gain).
Lina
* Lina's high damage burst from Dragon Slave, Light Strike Array and Laguna Blade can easily kill Chen's allies or Chen himself before he can use 
Hand of God.
Additional:
* Lina's high damage burst from Dragon Slave, Light Strike Array and Laguna Blade can easily kill Chen's allies or Chen himself before he can use Hand of God.
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.
Juggernaut
* Illusion-based heroes are effective against Omnislash and Juggernaut's single-targeted damage: Naga Siren, Chaos Knight, Terrorblade,Phantom Lancer.
Juggernaut
* Heroes whose core item builds includes 
Monkey King Bar: Faceless Void, Windranger, 
Weaver, Juggernaut.
Lina
* Laguna Blade is one of the best tools to kill Terrorblade before he can use 
Sunder due to its high magical damage.
* Dragon Slave and Light Strike Array allows Lina to clear Terrorblade's illusions from both, Conjure Image and 
Manta Style.
* Lina commonly buys items that allow her attacks to deal magical damage to Terrorblade that can ignore his high armor, like 
Gleipnir, Monkey King Bar or Revenant's Brooch.
Additional:
* Laguna Blade is one of the best tools to kill Terrorblade before he can use Sunder due to its high magical (pure with Laguna Blade damage is Pure and pierces Spell Immunity talent) burst damage.
* Dragon Slave and Light Strike Array allows Lina to clear Terrorblade's illusions from both, Conjure Image and Manta Style.
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.
Lina
* Venomancer has low health, which makes him vulnerable to Lina's heavy magic damage.
* Fiery Soul attack speed bonus removes 
Plague Wards easily in all stages of the game.
Lina
* 
Moonlight Shadow does little good against Dragon Slave and Light Strike Array.
* Lina's damage burst can quickly kill Mirana's teammates before she saves them with Moonlight Shadow.
Additional:
* Eul's Scepter of Divinity is an item Lina commonly buys, which in combination with and Light Strike Array can disable Mirana if she tries to Leap away.
* Laguna Blade's magical (pure with Laguna Blade damage is Pure and pierces Spell Immunity talent) burst damage takes advantage of Mirana's below average health.
Juggernaut
* Illusion-based heroes are effective against Omnislash and Juggernaut's single-targeted damage: Naga Siren, Chaos Knight, Terrorblade,Phantom Lancer.
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.
Lina
* Heroes with summons and illusions can find themselves easily bested by Lina, like Broodmother, Nature's Prophet, Chen, Terrorblade, Naga Siren, Visage, Wraith King, Lycan, Phantom Lancer, Shadow Shaman.
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.
Juggernaut
* Blade Fury protects Juggernaut from all of Tiny's magic burst damage.
Lina
* Lina can outlanes Shadow Fiend on the central line, due to the fact that Lina's attack range exceeds the attack range of Shadow Fiend, which makes it difficult for him to fend off her attacks and approach creeps, thus Lina has more level and gold.
* Lina can defeat Shadow Fiend with the combination of her abilities on lane and during teamfights: Light Strike Array, Dragon Slave, Laguna Blade, Shadow Fiend does not have a large pool of health before buying items for extra strength and health like 
Satanic, which is why Lina's strong magic damage is enough to kill him quickly.
Additional:
* Outlanes Shadow Fiend on the central line, due to the fact that Lina's attack range exceeds the range of Shadow Fiend, which makes it difficult for him to fend off her attacks and approach creeps, thus Lina has more level and gold
* Defeats Shadow Fiend` from Burst with a combination of skills: Light Strike Array, Dragon Slave, Laguna Blade, Shadow Fiend does not have a large pool of health before buying an item: Satanic , which is why Lina's strong magic damage is enough to kill him quickly
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.
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).
Juggernaut
* Blade Fury allows Juggernaut to simply move out of Kinetic Field and 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.
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.
Lina
* Lina's damage burst can quickly kill Clinkz before he saves them with 
Skeleton Walk.
* Fiery Soul attack speed bonus removes 
Burning Army easily in all stages of the game.
Lina
* Light Strike Array in combination with Dragon Slave can easily clear Broodmother's spiders.
* Laguna Blade offers extensive damage that can kill Broodmother early on or before she is able to use Insatiable Hunger in attempts to salvage a fight.
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.
Lina
* Heroes with powerful spammable abilities will prove problematic for Grimstroke as Ink Swell does not protect him from them: Zeus, Skywrath Mage, Tinker, Lina
Lina
* Abilities that can destroy trees can give Hoodwink a disadvantage: 
Timbersaw, Windranger, Lina.
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, Medusa, Dawnbreaker.
Lina
* Heroes with summons and illusions can find themselves easily bested by Lina, like Broodmother, Nature's Prophet, Chen, Terrorblade, Naga Siren, Visage, Wraith King, Lycan, Phantom Lancer, Shadow Shaman.
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.
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.
Lina
* 
Mind Flare does tons of damage against Lina because of her high intelligence.
* 
Vendetta can deal heavy damage to Lina while also burning her mana, preventing Lina from casting her abilities.
* 
Spiked Carapace can easily be used to counter Lina's abilities because of their long cast animation, and could probably kill Lina outright if Laguna Blade is reflected. However, Lina can counter this with Eul's Scepter of Divinity, a common item on Lina.
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.
Lina
* Heroes who build Black King Bar as either core or situational item will be able to fight back against Nyx Assassin and freely attack him as Spiked Carapace cannot pierce spell immunity at all: 
Axe, Broodmother, Dawnbreaker, Enigma, Huskar, Jakiro, 
Legion Commander, Lina, Luna, Lycan, 
Slardar, Slark, Troll Warlord, 
Witch Doctor.
Lina
* Heroes who rely on armor or evasion to survive can easily be bursted down, like Phantom Assassin, Terrorblade, Underlord, Spirit Breaker.
Lina
* Heroes who have channeled abilities can be stunned by Light Strike Array, like Witch Doctor with 
Death Ward and Bane's 
Fiend's Grip.
Additional:
* Light Strike Array cancels out Death Ward from a long distance.
Juggernaut
* Heroes with spell immunity: Juggernaut, 
Pangolier, Huskar.
Lina
* Heroes that can kill Death Prophet with nukes can prevent her from using Exorcism to its full duration or using it at all: Lina, Lion, Puck, Morphling.
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
* 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.
Lina
* Heroes with summons and illusions can find themselves easily bested by Lina, like Broodmother, Nature's Prophet, Chen, Terrorblade, Naga Siren, Visage, Wraith King, Lycan, Phantom Lancer, Shadow Shaman.
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.
Lina
* Heroes who rely on armor or evasion to survive can easily be bursted down, like Phantom Assassin, Terrorblade, Underlord, Spirit Breaker.
Lina
* Heroes with summons and illusions can find themselves easily bested by Lina, like Broodmother, Nature's Prophet, Chen, Terrorblade, Naga Siren, Visage, Wraith King, Lycan, Phantom Lancer, Shadow Shaman.
Lina
* Heroes with long animations can be frequently interrupted with Cold Snap: 
Earthshaker, 
Monkey King, Shadow Fiend Lina
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.
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.
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.
Lina
* Lina has a very long range of attack, which completely overlaps the range of Queen of Pain's abilities and attacks, which is why even a single 
Shadow Strike roll can become deplorable, since Lina will shoot Queen of Pain from a long distance before and after the Shadow Strike roll. And with the help of the abilities of Light Strike Array and Laguna Blade, Lina can even kill Queen of Pain because of her small health reserve if she is exposed to a blow

And with the help of Light Strike Array and Laguna Blade, Lina can even kill Queen of Pain because of her small health reserve if she is exposed to a blow.
Lina
* Fragile support heroes are all ideal targets for the Phantom Assassin. Heroes such as Lina and Witch Doctor are all prime targets that may not be able to react quickly and fight back due to Phantom Assassin's sudden appearance.
Lina
* Laguna Blade is one of the best tools to kill Phantom Assassin before she can do anything in early-to-mid game due to its high magical (pure with Laguna Blade damage is Pure and pierces Spell Immunity talent) burst damage.
* 
Blur offers no protection against Lina's abilities. Likewise, Lina can counter Blur's evasion by buying either Silver Edge or Monkey King Bar.
* Lina just has to be careful about 
Fan of Knives from Aghanim's Shard and 
Coup De Grace, as Fan of Knives can deal pure damage to Lina and disable Fiery Soul awhile Coup De Grace can deal serious damage to her even if she is spell immune, which may force Lina to buy Ethereal Blade to deal with Phantom Assassin.

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.
Lina
* Dragon Slave will make quick work of the spawned illusions from Disruption.
* An attempt to save an ally using Disruption can easily become a perfect setup for a Light Strike Array for the enemy.
* Shadow Demon doesn't have the burst damage to take Lina out of the fight quickly, although Demonic Purge can help his allies kill a squishy Lina.
Juggernaut
* Juggernaut's Omnislash is meaningless for Meepo who can share the damage across clones to save other allies.
Lina
* Light Strike Array can catch Meepo and his clones off-guard if he tries to gank Lina with 
Earthbind & 
Poof.
* Laguna Blade can quickly kill Meepo and his clones before they escape with Poof.
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.
Lina
* Light Strike Array and Dragon Slave allows Lina to destroy trees, countering 
Nature's Guise and 
Eyes in the Forest.
* Lina has many tools to bypass 
Living Armor's protection.
Lina
* Templar Assassin can outmatch Lina on the center line thanks to her own 
Psi Blades, which is why the advantage of Lina's long-range attacks become turned against her.
* 
Refraction is good defense against Lina's burst damage. But remember that Lina can partially counter this with Dragon Slave's damage over time.
Additional:
* Outlanes Lina on the center line thanks to her own Psi Blades, which is why the advantage of Lina's long-range attacks become turned against her
* Closes from Lina's magic attacks with her own Refraction, which is why Lina can't make her combination: Light Strike Array, Dragon Slave, Laguna Blade and kill Templar Assassin quickly
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
* 
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.
Lina
* Dragon Slave deals reliable magic damage during the laning phase against Mars.
* Lina's Eul's Scepter of Divinity and Light Strike Array combo can interrupt Mars from being disruptive for a decent amount of time and leave him vulnerable for follow up stuns.
* Laguna Blade deals massive magical damage, and pure damage with Aghanim's Scepter.
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.
Lina
* Lina defeats Sniper on the mid, because she has the same attack range as him, and her Dragon Slave ability deals much more damage to creeps, as well as to Sniper himself, than 
Shrapnel, which creates uncomfortable conditions for Sniper to farm on the line, which is why Lina either punches Sniper harder than he either pushes a pack of creeps up to the tower and finishes off his creeps under it, preventing Sniper from earning gold and a level.

Lina
* Heroes with high burst damage through their physical attacks or spells can kill Dazzle or his allies before he has a chance to use Shallow Grave. (Lina, Lion, etc.)
Additional:
* Laguna Blade can kill Dazzle quickly before he casts 
Shallow Grave.
Lina
* 
Spectral Dagger and 
Haunt allow Spectre to get close to Lina.
* 
Desolate is very strong against Lina, who's usually a bit isolated in fights because of her high attack and cast range.
* 
Dispersion can mitigate a good portion of Lina's burst damage, allowing Spectre to turn on her afterwards.
Additional:
* Spectre can very easily close the distance on Lina with Haunt and Spectral Dagger, and due to Lina's abysmal mobility without a Blink Dagger and terrible health pool and armor, Lina easily gets slaughtered due Desolate.
* Dispersion can mitigate a good portion of Lina's burst damage, allowing Spectre to turn against her afterwards.
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.
Lina
* Heroes that can close the gap can easily chase Lina down, such as Timbersaw with 
Timber Chain and Anti-Mage with Blink.
Lina
* Timbersaw has a difficult time against magical and pure damage: Lina, Leshrac, 
Enchantress, Queen of Pain
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.
Lina
* Heroes with either magical, physical or pure damage burst: Bane, Ember Spirit, Leshrac, Lina, Luna, 
Nyx Assassin, Phantom Assassin, Skywrath Mage, Tinker, Ursa, 
Void Spirit.
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.
Lina
* Heroes who have channeled abilities can be stunned by Light Strike Array, like Witch Doctor with Death Ward and Bane's Fiend's Grip.
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.
Lina
* Heavy nukers will do well against Cold Embrace (Lina, Zeus etc).
Lina
* Heroes with low mobility that rely on spells: Zeus, Lina, Crystal Maiden.
Juggernaut
* Heroes with stronger lane presence that can threaten to kill him: Batrider, Juggernaut, Ursa, Monkey King, Razor.
Lina
* Heroes with a lot of burst damage, especially those who rely on casting spells: Lina, Zeus.
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.
Juggernaut
* 
Guardian Angel completely negates all physical damage, including Omnislash.
Additional:
* Omnislash (and Swiftslash) is blocked by Guardian Angel.
Lina
* Guardian Angel is generally useless against Lina as she primarily relies on magical damage. Lina can also dispel it with Eul's Scepter of Divinity as she is a hero who often goes for it. Eul's Scepter of Divinity can later be upgraded into 
Wind Waker, which will allow Lina to escape from Omniknight.
* Laguna Blade can often finish off Omniknight's allies before he can save them with 
Purification and 
Repel. This can become even worse once Lina picks Laguna Blade damage is pure and pierces spell immunity talent, which will allow it to ignore both, any form of spell immunity and Guardian Angel.
Juggernaut
*
Fury Swipes is not protected by 
Blade Fury and allows Ursa to harass Juggernaut anytime.
Enrage reduces the damage taken from 
Omnislash.
*
Lina
*
Light Strike Array has a long delay, making her vulnerable for Ursa's burst.
* Enrage can protect Ursa against Lina's high magical burst.
