* Hard-hitters who relies mostly on raw stats or good passive and therefore make a perfect target for Dark Portrait: Naga Siren, Faceless Void, Terrorblade, Luna, Anti-Mage

* 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.

* 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.

* Phantom's Embrace can silence Crystal Maiden and disrupt Freezing Field's channeling. Her slow movement speed and fragile nature will also make her an easy target for Stroke of Fate and Ink Swell.

* 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.

* Ghost Shroud amplifies damage taken from all of Grimstroke's abilities. Necrophos is particularly vulnerable to Ink Swell and Phantom's Embrace while in Ghost Shroud.
* Death Pulse works against Necrophos in lane by keeping his creeps alive and add damage to Stroke of Fate.

* Blade Fury and Omnislash allows Juggernaut to avoid Gyrocopter's area attacks entirely.

* Phantom's Embrace silences Viscous Nasal Goo and Quill Spray.
* Ink Swell stuns Bristleback and gets allies in position faster with increased movement speed to attack his front, countering his passive ability.

* Blade Fury dispels the slow from enchant, and can burst her 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.

* 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.

* 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 picks the level 20 talent that removes the mana cost from Reincarnation.

* Stroke of Fate deals more damage when it hits more targets which makes it very effective in dealing with Lycan and his units.
* Soulbind prevents lycan from running away and makes him very easy to deal with.

* Blade Fury protects Juggernaut from all of Tiny's magic burst damage, as well as dealing magic damage that bypasses the armor from Grow.

* 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.

* Blade Fury allows Juggernaut to simply move out of Kinetic Field and to dodge Glimpse.
* Healing Ward can keep heroes trapped in the Static Storm alive.
* Omnislash can be used to dodge Glimpse.

* Phantom's Embrace and Soulbind prevent Weaver from using Shukuchi or Time Lapse to escape.
* Ink Swell discourages Weaver from moving through and damaging allies with Shukuchi.

* Soulbind ignores spell immunity, forcing Pangolier to roll in place during his ultimate as well as anchoring the other victim to his vicinity.

* Juggernaut can attack Remote Mines and trigger Proximity Mines while in Blade Fury.

* Timbersaw relies heavily on his abilities so Phantom's Embrace's silence makes it more difficult for him.
* Timbersaw cannot use Return Chakram or attack the phantom during Phantom's Embrace, forcing him to take full damage and refreshes Phantom's Embrace's cooldown.

* 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 > Sun Strike combo a threat if he does not dodge Tornado.
Additional:
* 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.

* None of Dark Willow's spells pierce Spell Immunity, making Blade Fury a good counter against her.
* 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).
Additional:
* 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.

* Phantom's Embrace stops Anti-Mage from Blinking away.
* Soulbind stops Blink and lets allies cast abilities on the tethered target to avoid Counterspell. It cannot be reflected by Counterspell.

* Juggernaut's low mana pool means that Mana Break and Mana Void will deal little damage to him. His Blade Fury allows him to Block the damage from Mana Break

* Blade Fury completely counters all of Nyx Assassin's abilities except Vendetta, and does not allow him to disengage with Spiked Carapace.
* Omnislash makes quick work of Nyx Assassin, and Spiked Carapace offers no protection at all.

* Soulbind pierces spell immunity and prevents Faceless Void from escaping with Time Walk.

* 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.

* Grimstroke's Soulbind will always reliably connect onto both of them if they are close together.

* 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, any engagement with Power Cogs will hurt Clockwerk a lot more than 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

* 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,Drow Ranger.

* Heroes with powerful channeling abilities are easily interrupted by Phantom's Embrace: Bane, Pudge, Witch Doctor, Crystal Maiden, Enigma.

* 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.

* 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.

* 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.

* 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.

* Heroes with spell immunity: Juggernaut, Pangolier, Huskar.

* Heroes with stronger lane presence that can threaten to kill him: Batrider, Juggernaut, Ursa, Monkey King, Razor.

* Heroes with area of effect abilities that increase in power based on the number of units struck: Legion Commander, Grimstroke.

Additional:
* Stroke of Fate can deal heavy damage to Broodmother and her spiders, and with enough spiders it can kill her instantly.
* Phantom's Embrace provides vision on Broodmother when she's fleeing into the trees.

* 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.
* Keeper of the Light has low health, low armor, and no natural defense against Omnislash.

* Stroke of Fate clears Phantom Lancer's illusion easily as it deals bonus damage to more targets.
* Ink Swell can be used on an allied hero or Grimstoke himself to stun Phantom Lancer and his illusions.
* Phantom's Embrace and Soulbind have an undispellable debuff that can be used to mark the real Phantom Lancer.
Additional:
* Stroke of Fate's damage increases the more units are hit by it, making it effective against Phantom Lancer's army of illusions.
* Phantom's Embrace and Ink Swell's stun can prevent Phantom Lancer from escaping with Doppelganger if properly timed.
* If he has already used Doppelganger, Soulbind can tie Phantom Lancer to one of his own illusions to keep him in place, or to ensure a kill if Grimstroke's team is unsure which one is the real hero.

* Terrorblade's lack of escape mechanisms makes it hard for him to escape both Ink Swell and Stroke of Fate.
* Phantom's Embrace's silence will also prevent him from casting Sunder to save himself.

* 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.

* Grimstroke can catch Io and his ally easily with SoulBind as Io has a tendency to tether himself with an ally frequently.
* Io is highly vulnerable to disables. Hence, Grimstroke's Phantom's Embrace is a great ability to hinder Io's potential.
Additional:
* Soulbind can target both Io and its Tethered ally, allowing Grimstroke and his team to target both with single target spells. Should Io try to Relocate, Phantom's Embrace can stop its channel to prevent escape.

* 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.

* 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.

* Heroes who are reliant on illusions or summons: Chaos Knight, Broodmother, Naga Siren.

* Skywrath's pitiful defences also make him easy meat to heroes with high physical burst like Juggernaut or Phantom Assassin, the latter occasionally downing a support Skywrath in a single Stifling Dagger.

* 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.

* 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.

* In general, heroes with spell immunity abilities won't be caught inside by Pit of Malice: Juggernaut, Lifestealer.
