* Heroes who can summon illusions and summons because Terrorblade has no abilities to deal with multiple enemies at once outside Reflection: Shadow Shaman, Naga Siren, Broodmother, Lycan, Enigma, Chaos Knight, Phantom Lancer, Shadow Demon, Dark Seer, Nature's Prophet, Invoker, Morphling, Visage, Grimstroke with Aghanim's Scepter.

* 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.

* Heroes with both illusions and summons, for Io has nothing to deal with multiple enemies at once outside from Spirit's weak area-of-effect: Broodmother, Chaos Knight, Lycan, Naga Siren, Nature's Prophet, Phantom Lancer, Shadow Shaman, Terrorblade, Visage, Warlock.

* 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.
Additional:
* 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.

* Lycan's ultimate makes him immune to slows from Ursa's Earthshock as well as allowing him to outmaneuver Ursa during Enrage. Lycan can also easily chase down Ursa while shapeshifted, should Ursa try to flee.

* Heroes who rely heavily on melee attacks and lack early spell immunity are easily blocked and interrupted by Ink Swell: Lycan, Ursa, Troll Warlord.

* Heroes with single-target abilities will be overwhelmed by Lycan and his summons: Wraith King, Bane, Phantom Assassin.

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

* Howl reduces a good chunk of Marci's attack damage that she relies heavily on, and the armor reduction works better on her because of her low armor.
* Shapeshift renders Lycan immune to slow from Rebound and Unleash.

* He can send wolves to defuse Proximity Mines, and he can catch up Techies and kill him before they can deny themselves. Even if the suicide is successful, Lycan can still survive because of his tankiness.

* 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.

* Shapeshift allows Lycan to chase down Earth Spirit.

* Phantom's Embrace is very threatening due to Primal Beast being quite spell reliant, and not being able to attack during Trample and can immediately cancel Pulverize.
* Soulbind can prevent movement in a way that's very hampering for Primal Beast's Trample and Onslaught. It can also cancel Onslaught very abruptly.
* Ink Swell can stun Primal Beast and give the holder a strong dispel with the shard. The stun can easily stop Trample damage or Pulverize from continuing even if it's not Primal Beast's main target.

* Lycan's high HP easily shrug off Nyx Assassin's burst damage and fend him off.

* Shapeshift increases Lycan's movement speed and renders him unslowable, allowing him to easily avoid and escape Ancient Apparition's abilities.
* Lycan has fast summons, both his wolves from Summon Wolves can do heavy damage to Ancient Apparition due to his immobility and low armor.

* 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.

* 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.
Additional:
* 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.
* Soulbind has an undispellable debuff that can be used to mark the real Phantom Lancer. It also prevents him from using Doppelganger.

* 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.

* Shapeshift allows Lycan to escape from Upheaval with maximum movement speed.
* Warlock doesn't have a good solution to deal with Lycan's wolves from Summon Wolves.

* Lycan doesn't care much about Lich's slows thanks to Shapeshift.
* Chain Frost can bounce to the wolves that Lycan summons.
Additional:
* Lich possesses a lot of slows, which Lycan doesn't care about when he Shapeshifts.
* Lich has no in-built escape, which makes him a good target for Lycan.

* Shapeshift allows Lycan to get close and disable Marksmanship.
* Shapeshift also makes him immune to slows like Drow Ranger's Frost Arrows.
Additional:
* The Wolves' speed causes the knockback from Gust to be ineffective.
* She lacks escapes and loses her Marksmanship when someone is near her. Lycan takes advantage of these weaknesses.

* The movement speed granted from Shapeshift means that Spectre has no way to punish Lycan if he wants to splitpush or pick off supports. Furthermore, he will kite Haunt and cannot be slowed by Spectral Dagger.
* Lycan is often part of an early game push strategy which is often the best counter to Spectre because she needs a lot of time and space to come online as a late game carry.

* Void's slow is useless against Lycan by activating Shapeshift.
* Night Stalker's single target abilities (with the exception of Void upgraded by Aghanim's Scepter) is not very effective against Lycan's Summon Wolves during the early and mid game.

* Shapeshift is useful for killing or escaping Silencer.
* Summon Wolves, can be used to hunt and harass silencer - even when Lycan himself can't fight.

* Magnetic Field is useless against melee heroes, so Lycan can attack Arc Warden without missing.
* Flux doesn't affect Lycan that much, because Shapeshift grants immunity to slows and because he is never alone.
* If their Tempest Double has been called, Lycan can still kill Arc Warden before the double expires.

* Mirana's Leap is ineffective if Lycan uses Shapeshift. It also allows him to dodge Sacred Arrow.

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

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

* Heroes with single-target abilities will be overwhelmed by Lycan and his summons: Wraith King, Bane, Phantom Assassin.

* Windranger heavily relies on her abilities for any form of tactical advantage and damage. A well timed silence will make her useless: Puck,Silencer, Death Prophet, Skywrath Mage, Drow Ranger, Earth Spirit, Grimstroke.

* Heroes with summons: Lycan, Broodmother, Visage, Nature's Prophet, Warlock.

* Heroes who do not have nor rely on passive abilities make Nethertoxin much less effective: Clinkz, Pugna, Nature's Prophet, Dark Seer, Lycan, Tusk

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

* 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

* Heroes who rely heavily on melee attacks and lack early spell immunity are easily blocked and interrupted by Ink Swell: Lycan, Ursa, Troll Warlord.

* Illusion and heroes with summons are difficult to kill with Chen's single-target offensive spells: Terrorblade, Phantom Lancer, Chaos Knight, Broodmother, Naga Siren, Lycan, Visage. And even though Chen can convert enemy summons with Holy Persuasion, their much greater numbers will often overwhelm Chen and his creeps.

* Heroes with low armor and little mobility, like Huskar, Io, etc. will also have an unfortunate fate.

* 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.

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

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

* Phantom's Embrace can't be dispelled by Slark's Dark Pact.

* A combination of Soulbind and Phantom's Embrace can prevent Anti-Mage from casting spells.
* If Grimstroke has Aghanim's Scepter, Dark Portrait can reflect Anti-Mage's Mana Break making useful in team fights.

* 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.

* 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.

* Multiple attackers thanks to summoned units or clones: Meepo, Witch Doctor, Lycan, Enigma, Shadow Shaman
* Heroes that can quickly deal damage to her, regardless of how weak they are, can easily break through her Refraction:
* Multiple attackers thanks to summoned units or clones: Meepo, Witch Doctor, Lycan, Enigma, Shadow Shaman
* Multiple attackers thanks to illusions: Phantom Lancer, Chaos Knight, Naga Siren (bonus for her Ensnare). Also despite the visual effects, Templar Assassin does not spill damage against illusions or buildings, so she is not a really good hero to clean up illusions.
* Weak damage but high tick rate or persist in a long time: Slark, Gyrocopter, Queen of Pain, Shadow Shaman (Shackles), Jakiro, Pugna

* Heroes with hastes: Dark Seer, Lycan

* Once you get a Black King Bar, squishy spellcasters like Zeus, Skywrath Mage and others will be probably easy to deal with.
