Tiny
* Heroes with Evasion or abilities that cause Tiny to miss like 
Phantom Assassin and 
Tinker are very effective because of Tiny's low attack speed. Additionally, 
Monkey King Bar is not a good item for Tiny because of its reliance on high attack speed to proc for magical damage.
Grimstroke
* Heroes with powerful spammable abilities will prove problematic for Grimstroke as Ink Swell does not protect him from them: 
Zeus, 
Skywrath Mage, Tinker, 
Lina
Grimstroke
* 
Nether Swap breaks one ally out of Soulbind, and can be used to redistribute the shared damage to Vengeful Spirit herself.
Tiny
* Dual Breath and Liquid Fire reduces Tiny's already abysmal Attack Speed.
* If Tiny 
Tosses a hero onto Jakiro, he can react with Ice Path, and potentially Macropyre.
* Tiny's 
Avalanche is easily countered with Ice Path.
* As Tiny has a very high Health, Liquid Frost is particularly effective against him.
Grimstroke
* 
Stampede can allow Soulbinded heroes to just ran away.
Tiny
* Avalanche and Toss will never be enough damage to take out Sven in a clean way.
* Tiny is very slow with low armour growth and does not buy items to sustain Sven's damage output.
Tiny
* Tiny has low movement speed and attack speed, making him vulnerable to Viper's slows.
* 
Corrosive Skin provides magic resistance to lower Tiny's magic burst damage.
Tiny
* 
Feast will deal a enormous amount of damage because of Tiny's huge health pool.
* 
Rage protects Lifestealer from Tiny's magical burst damage.
Grimstroke
* 
Disruption instantly removes Phantom Embrace, and can potentially save allies affected by Soulbind.
* 
Demonic Purge dispels Ink Swell.
Tiny
* 
Blade Fury protects Juggernaut from all of Tiny's magic burst damage.
Grimstroke
* 
Phase Shift can easily disjoint Phantom Embrace and waste half of the Soulbind's duration.
* Puck is very mobile hero who can jump backsides and burst Grimstroke before he can cast anything.
Tiny
* Primal Roar and the slow from Boars make kiting Tiny very easy.
Grimstroke
* 
Stroke of Fate provides Rubick with a short cooldown nuke.
* Note that Rubick uses a fixed 0.15 second cast time for the skill, much shorter than the 0.6 second cast time for Grimstroke.
* 
Phantom's Embrace is an unique ability with extra silence and damage.
* 
Ink Swell is a great initiation/counter-initiation ability for frontliners.
* With 
Telekinesis, Rubick can grant extra duration for Phantom's Embrace's phantom latch, or throw an enemy within the area covered by Ink Swell.
* 
Soulbind, as a powerful ultimate, gives Rubick extra crowd control and sows chaos among enemies.
* Both Telekinesis and 
Fade Bolt are single-target abilities, and can be applied twice on the enemy. The damage of Fade Bolt is effectively doubled as the bounce is very likely to happen as the bound heroes must walk together.
Tiny
* Heroes with naturally low mana can be easily shut down by E.M.P.: 
Sven, 
Tiny, 
Wraith King, 
Omniknight
Grimstroke
* Heroes with powerful spammable abilities will prove problematic for Grimstroke as Ink Swell does not protect him from them: Zeus, Skywrath Mage, Tinker, Lina

* Heroes with Evasion or abilities that cause Tiny to miss like Phantom Assassin and Tinker are very effective because of Tiny's low attack speed. Additionally, Monkey King Bar is not a good item for Tiny because of its reliance on high attack speed to proc for magical damage.
Tiny
* Due to Tiny's non-existent agility gain, high physical damage heroes are more effective against him (
Clinkz, 
Templar Assassin, 
Ursa, Wraith King etc).
Tiny
* Due to Tiny's non-existent agility gain, high physical damage heroes are more effective against him (Clinkz, Templar Assassin, Ursa, Wraith King etc).

Tusk and 
Phoenix, will greatly limit his Physical damage output.
Tiny
* He can quickly take out heroes with low armor (Tiny) with his great physical damage.
Tiny
* In general, melee heroes without blink mechanisms or spell immunity will have a hard time positioning against Pit of Malice: Sven, Tiny, Wraith King, 
Dragon Knight, 
Meepo, 
Doom, 
Bounty Hunter, 
Dark Seer, 
Undying, 
Alchemist, 
Legion Commander.
Grimstroke
* Heroes with powerful spammable abilities will prove problematic for Grimstroke as Ink Swell does not protect him from them: Zeus, Skywrath Mage, Tinker, Lina
Tiny
* Due to Tiny's non-existent agility gain, high physical damage heroes are more effective against him (Clinkz, Templar Assassin, Ursa, Wraith King etc).
Grimstroke
* Fragile supports with low armor are always a good prey, also her Psionic Trap will wear down most attempts to flee with their built-in disables: 
Silencer, 
Crystal Maiden, 
Warlock, 
Ancient Apparition, 
Grimstroke, 
Witch Doctor
Tiny
* Heroes that have disposable area-targeted spells can force her to undo her Meld: 
Leshrac, 
Puck, Tiny, 
Jakiro,. An experienced Templar Assassin could try to use Refraction before Meld so she can tank through those damage without getting her Blink disabled.
Tiny
* Heroes that are able to slow Tiny's attack speed, like Tusk and Phoenix, will greatly limit his Physical damage output.
Tiny
* Long ranged heroes like 
Sniper or 
Drow Ranger can kite Tiny effectively if he doesn't get the jump on them first.
Grimstroke
* Heroes with mobility spells can quickly escape from Stroke of Fate or break out of Soulbind: Anti-Mage, Queen of Pain, Morphling, Storm Spirit
Grimstroke
* Heroes with mobility spells can quickly escape from Stroke of Fate or break out of Soulbind: Anti-Mage, Queen of Pain, Morphling, Storm Spirit
Tiny
* 
Chaos Bolt and 
Reality Rift makes Tiny's low mobility non existent.
* 
Chaos Strike means Chaos Knight will most likely survive longer in a duel between the two because Tiny has much lower attack speed.
* Chaos Knight has a 3.2 strength growth, making him one of the most tanky heroes and a very difficult target for Tiny to burst.
Grimstroke
* Heroes who are reliant on illusions or summons: 
Chaos Knight, 
Broodmother, 
Naga Siren.
Tiny
* Toss and Avalanche deals heavy damage to Slark in the early game, making Tiny a very dangerous target to gank.
* Tiny has 0 agility, which means Slark's 
Essence Shift permanent agility steal does not do much against him.
Grimstroke
* Phantom's Embrace cannot be dispelled by Slark's 
Dark Pact, and will cause him to suffer damage if he doesn't kill Phantom fast enough.
* Soulbind also cannot be dispelled by Slark's Dark Pact, and will cause Slark to suffer from a single-targeted ability used on his ally that is also affected by it.
Tiny
* Avalanche and Toss combo makes short work of 
Mirror Image's illusions.
* Tiny's cleave with Tree Grab and area of effect damage with Tree Volley will easily wipe out illusions.
Grimstroke
* Heroes who are reliant on illusions or summons: Chaos Knight, Broodmother, Naga Siren.
Tiny
* Tiny can quickly clear Spiderlings with his active abilities and cleave.
Grimstroke
* Heroes with area of effect abilities that increase in power based on the number of units struck: 
Earthshaker, 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.
Grimstroke
* 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.
Grimstroke
* 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.
Grimstroke
* Soulbind ignores spell immunity, forcing Pangolier to roll in place during his ultimate as well as anchoring the other victim to his vicinity.
Grimstroke
* Soulbind pierces spell immunity and prevents Faceless Void from escaping with Time Walk.
Grimstroke
* 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.
Grimstroke
* 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.
Grimstroke
* 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.
Grimstroke
* Grimstroke's Soulbind will always reliably connect onto both of them if they are close together.
Grimstroke
* Heroes with powerful channeling abilities are easily interrupted by Phantom's Embrace: 
Bane, 
Pudge, Witch Doctor, Crystal Maiden, 
Enigma.
Grimstroke
* 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
Grimstroke
* 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.
Tiny
* Squishy heroes, usually supports, like 
Lion, Ancient Apparition, 
Keeper of the Light etc can die quickly to Tiny's magic burst.
Grimstroke
* Heroes with powerful channeling abilities are easily interrupted by Phantom's Embrace: Bane, Pudge, Witch Doctor, Crystal Maiden, Enigma.
Tiny
* Side lanes with disables will greatly reduce the likeliness Void Spirit will be willing to rotate: Sven, Tiny, Wraith King, 
Ogre Magi.
Grimstroke
* Heroes with powerful channeling abilities are easily interrupted by Phantom's Embrace: Bane, Pudge, Witch Doctor, Crystal Maiden, Enigma.
Grimstroke
* Any ganking heavy support can be a big problem for Primal Beast, such as: Earth Spirit, Grimstroke before he has a 
Black King Bar.
Tiny
* Squishy heroes, usually supports, like Lion, Ancient Apparition, Keeper of the Light etc can die quickly to Tiny's magic burst.
Grimstroke
* Heroes with powerful channeling abilities are easily interrupted by Phantom's Embrace: Bane, Pudge, Witch Doctor, Crystal Maiden, Enigma.
Grimstroke
* Heroes who rely heavily on melee attacks and lack early spell immunity are easily blocked and interrupted by Ink Swell: 
Lycan, Ursa, 
Troll Warlord.
Grimstroke
* Heroes who rely heavily on melee attacks and lack early spell immunity are easily blocked and interrupted by Ink Swell: Lycan, Ursa, Troll Warlord.
Additional:
* 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.
Tiny
* Tiny's Avalanche affects all Meepos and Toss can send a singular Meepo into death.
Additional:
* Avalanche and Toss prevents Meepo's from using 
Poof to escape.
* Tiny doesn't need to target the weakest clone while he is affected by Tree Grab.
Tiny
* Heroes with high base damage (Morphling, Tiny, Drow Ranger), heroes with mana burning abilities (Anti-Mage), and 
Diffusal Blade users (
Juggernaut or 
Riki) will suffer from Reflection's illusions.
Grimstroke
* 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.
Grimstroke
* Heroes with mobility spells can quickly escape from Stroke of Fate or break out of Soulbind: Anti-Mage, Queen of Pain, Morphling, Storm Spirit
Grimstroke
* 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 it useful in team fights.
Tiny
* 
Mana Drain has an fair long range and low cooldown. It can easily deplete most heroes of their entire mana pools, especially those with smaller mana pools such as Tiny or 
Spirit Breaker.
Additional:
* Lion can continuously Mana Drain Tiny in the early game, depleting his small mana pool for his abilities.
Tiny
* Squishy heroes, usually supports, like Lion, Ancient Apparition, Keeper of the Light etc can die quickly to Tiny's magic burst.
Tiny
* Due to Tiny's non-existent agility gain, high physical damage heroes are more effective against him (Clinkz, Templar Assassin, Ursa, Wraith King etc).
Grimstroke
* Heroes who rely heavily on melee attacks and lack early spell immunity are easily blocked and interrupted by Ink Swell: Lycan, Ursa, Troll Warlord.
Tiny
* Tiny's nonexistent armor in the early game makes him very vulnerable to 
Quill Spray's large amounts of physical damage.
* 
Bristleback decreases Tiny's high burst damage against Bristleback.
* 
Viscous Nasal Goo can slow Tiny to a crawl and allows Bristleback to easily kite him with his high movement speed and Quill Spray's long range, as Tiny has no ability to escape.
Grimstroke
* 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.
Tiny
* 
Reaper's Scythe will turn Tiny's high health against him.
* 
Heartstopper Aura does substantial damage to Tiny as a result of his high max health.
* 
Ghost Shroud protects Necrophos from Tiny's physical damage with Tree Grab and Tree Volley.
Grimstroke
* 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.
Tiny
* Familiars will easily be able to kite heroes with a short range or with low attack speed. For example, Tiny and Undying have a very hard time killing Familiars.
Tiny
* Tiny can deal with 
Visage's 
Gravekeeper's Cloak quickly, as Avalanche deals damage in enough instances to completely remove all 4 layers of the passive. With Visage's lower than average Armor, a well positioned stun can allow Tiny to kill Visage easily.
Additional:
* Tiny's Avalanche removes a significant number of layers from Gravekeeper's Cloak. When combined with Toss burns through all of Gravekeeper's Cloak while doing triple times Toss damage to Visage in midair.
* Tiny's already high damage coupled with 
Tree Grab's attack modifier will make short work of Visage's Familiars.
Tiny
* Long ranged heroes like
Sniper or 
Drow Ranger can kite Tiny effectively if he doesn't get the jump on them first.
Grimstroke
* Sniper's position in the far back line makes him unlikely to be hit by any of Grimstroke's abilities during teamfights.
* Sniper is relatively unaffected by the silence from Phantom's Embrace.
* Sniper's long range and fast projectile speed allows him quickly to destroy any Phantoms attacking his allies.
