Clinkz
* 
Scorched Earth deals damage to Clinkz during Skeleton Walk.
* 
Doom shuts down Clinkz entirely, as it prevents him from casting any of his spells and contributing a large amount of damage in teamfights.
Omniknight
* Doom applies a basic dispel upon cast, so it can remove 
Guardian Angel.
* Casting Doom on Omniknight will also prevent him from healing allies with 
Purification, or casting buffs like 
Repel and Guardian Angel, basically turning him into a harmless creep.
Additional:
* Doom turns Omniknight into a walking creep, or completely takes out his buffed cores, also removing Heavenly Grace and Guardian Angel in the process.
* With 
Devour used on Satyr Banisher, Doom will have access to Satyr Banisher's 
Purge, which will allow him to remove Heavenly Grace and Guardian Angel.
Clinkz
* 
Untouchable prevents Clinkz from harassing Enchantress in lane by lowering his attack speed.
* 
Nature's Attendants helps Enchantress to sustain through Clinkz's harassment in lane.
Omniknight
* Impetus is not blocked by Guardian Angel. A {U:Satyr Banisher} can also be controlled to dispel Guardian Angel.
Additional:
* Enchantress's 
Impetus deals pure damage instead of physical damage and ignores Guardian Angel, thus fully negating one of Omniknight's most important abilities for teamfights.
* Similar to Doom, Enchantress can use 
Enchant on Satyr Banisher, which will give her access to Satyr Banisher's Purge, and allow her to remove Heavenly Grace and Guardian Angel.
Clinkz
* The long silence at night prevents Clinkz from escaping with invisibility if Night Stalker can sneak up on him. He also has really low base health, so Night Stalker can usually kill him alone during one cast of Crippling Fear at night.
Omniknight
* Heroes that have a weak laning stage: 
Spectre, 
Nyx Assassin, 
Clockwerk, 
Spirit Breaker, 
Omniknight, 
Pudge.
Clinkz
* In general, Brewmaster's Cinder Brew and Thunder Clap makes him good against physical damage carries: 
Ursa, 
Clinkz, 
Faceless Void, 
Troll Warlord, 
Templar Assassin, 
Phantom Assassin.
Omniknight
* 
Dispel Magic from {U:Storm} instantly removes Heavenly Grace and Guardian Angel from Omniknight's allies in its radius of effect.
Clinkz
* 
Hex and 
Earth Spike can hold Clinkz down, giving him no chance to use 
Black King Bar or Skeleton Walk.
* 
Finger of Death quickly kills Clinkz due to his low health.
Omniknight
* Heroes who can drain mana can make Omniknight useless after he uses one or two abilities: 
Lion, 
Anti-Mage, Nyx Assassin.
Clinkz
* 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.
Omniknight
* Heroes with large physical resistance do not counter Muerta's Pierce the Veil such as Omniknight or 
Tidehunter.
Omniknight
* 
Global Silence takes Omniknight out of the fight completely.
* 
Glaives of Wisdom are a great harass vs Omniknight during the laning stages of the game, since it doesn't aggro creeps & ignores his high base armor. It deals pure damage, which means it can also go through Guardian Angel.
* Silencer's intelligence steal can also cause Omniknight to falter in the early phases as it reduces his ability to use his spells.
Omniknight
* 
Arcane Orb's pure damage penetrates Guardian Angel's defense.
* 
Astral Imprisonment's mana steal is devastating to Omniknight's already low mana pool.
Clinkz
* Zeus can reveal Clinkz with 
Lightning Bolt.
* He is vulnerable to Zeus's magical nukes, due to his low health pool.
Clinkz
* Clinkz will often roam the map alone, and Treant Protector's 
Nature's Guise allows him to set up kills with his allies on Clinkz from invisibility.
* Treant Protector's very high damage allowing him to trade hits or contest last hits with Clinkz, while 
Living Armor can be used to sustain the harass.
* Living Armor protects any of Treant's allies ganked by Clinkz.
* In teamfights, Treant Protector's 
Overgrowth can disarm Clinkz, preventing him from turning invisible and holding him in place even if he has a Black King Bar.
* 
Leech Seed slows Clinkz, preventing him from repositioning or fleeing away from danger.
Omniknight
* Guardian Angel does not offer protection from 
Eclipse, though it will negate damage from 
Moon Glaives.
* Luna's high magical damage from 
Lucent Beam and Eclipse can often finish allied heroes before Omniknight can save them with Purification.
* Likewise, Luna's high physical damage from Moon Glaives and 
Lunar Blessing is strong enough to counter debuff immunity from Repel.
Additional:
* Guardian Angel does not offer protection from Eclipse, though it will negate damage from Moon Glaives.
* Luna's high magical damage from Lucent Beam and Eclipse can often finish allied heroes before Omniknight can save them with Purification.
Clinkz
* Slardar can reveal Clinkz with 
Corrosive Haze and make him easy to kill, and his 
Bash of the Deep also hits hard against Clinkz's naturally low health pool.
* Slardar's 
Guardian Sprint can catch up with Clinkz's Skeleton Walk.
* The stun and slow from Slardar's 
Slithereen Crush can hold Clinkz in place.
Additional:
* Clinkz survivability depends entirely on 
Skeleton Walk. Corrosive Haze not only makes its invisibility useless, but also makes Clinkz even more vulnerable to physical damage.
Omniknight
* Jakiro's area-of-effect abilities that deal magical damsge make it hard for Omniknight to save multiple enemy heroes at once with Purification and Repel, and Guardian Angel and to harass Omniknight on lane.
* 
Aghanim's Scepter upgraded 
Macropyre allows Jakiro to deal pure damage and slow enemy heroes which can pierce debuff immunity, rendering both Repel and Guardian Angel useless.
Clinkz
* By using 
Morph, Morphling can use Burning Barrage and Searing Arrows to counter Clinkz himself.
* 
Waveform can allow Morphling to easily chase down Clinkz.
* Clinkz's low health pool also makes him vulnerable to Morphling's magical nukes, especially his 
Ethereal Blade and 
Adaptive Strike combo.
Omniknight
* Even though Naga Siren relies on direct attacks to deal damage for most of the time, Song of the Siren allows her to easily waste Guardian Angel.
* Ensnare fully works on targets affected with 
Heavenly Grace. However, Ensnare is dispellable with any dispel, and so can be dispelled by Heavenly Grace.
* As an agility hero that relies on illusions, Naga Siren is one of the most natural 
Diffusal Blade carriers, the bane of every hero with a small mana pool. Naga Siren can also buy items that deal magical damage like 
Radiance, 
Dagon, Ethereal Blade, 
Revenant's Brooch, 
Veil of Discord and 
Gleipnir to attack Omniknight's allies protected with Guardian Angel.
Additional:
* Although Naga Siren relies mostly on physical damage, 
Song of the Siren can be used to time out Guardian Angel, giving Naga Siren's team an easy opportunity to counter-initiate.
* Radiance allows it's owner to deal magical damage to multiple enemy heroes at once, and since Naga Siren often buys it, Guardian Angel is not a very good ability for protection against Naga Siren.
* Likewise, Nuker build Naga Siren (which primarly consists of items such as Radiance, Ethereal Blade, Dagon and Veil of Discord) can render Guardian Angel useless. Although Nuker is not a role Naga Siren should be playing.
Omniknight
* 
Mortimer Kisses can reduce Omniknight's impact in teamfights. Omniknight's Heavenly Grace cannot purge multiple stacks of Mortimer Kisses. The damage is also magical, making Omniknight's ultimate, Guardian Angel, useless.
Omniknight
* Jingu Mastery will still add stacks even through Guardian Angel.
* Monkey King can join a fight whenever he chooses to, meaning he can simply go directly onto Omniknight.
* During the laning phase, Jingu Mastery with Boundless Strike will kill off Omniknight, while Purification is weak.
* Heavenly Grace is useless against Monkey King's ultimate and Jingu Mastery bonuses.
Omniknight
* Heroes with large magical AoE damage will fare well against Omniknight: 
Lich, 
Ancient Apparition, 
Jakiro, 
Disruptor.
Clinkz
* Heroes that excel at grouping up with their team very early will be able to take advantage of a Clinkz that tries to pick off heroes that are alone: 
Brewmaster, 
Dazzle, Tidehunter.
Omniknight
* Heroes who can drain mana can make Omniknight useless after he uses one or two abilities: Lion, Anti-Mage, Nyx Assassin.
Clinkz
* Sand King is a strong ganker, allowing him to shut down squishy heroes in the early game: Phantom Assassin, Clinkz, Sniper, 
Enchantress.
Omniknight
* Heroes with long cooldowns on their abilities or ultimate will struggle against the relentless pressure provided by 
Fiend's Gate: Terrorblade, 
Dragon Knight, Omniknight.
Omniknight
* Heroes that can purge buffs can dispel Guardian Angel: 
Invoker, 
Shadow Demon, 
Oracle.
Additional:
* Demonic Purge can dispel Guardian Angel on the key target during combat, allow your allies to finish them.
Clinkz
* Heroes with high armor like Dragon Knight, or with abilities to cause attacks to miss like Phantom Assassin, 
Riki and 
Tinker will be hard to deal with, as Clinkz relies almost entirely on physical attacks.
Omniknight
* Heroes with naturally low mana can be easily shut down by E.M.P.: 
Sven, 
Tiny, 
Wraith King, Omniknight
Additional:
* 
Tornado dispels Heavenly Grace and Guardian Angel from multiple targets.
* Guardian Angel is generally useless against Invoker as he primarily relies on magical damage.
* 
E.M.P. depletes Omniknight's already small mana pool.
* Invoker's many disables keep Omniknight's team occupied until Guardian Angel times out.
Clinkz
* Even though 
Linken's Sphere will block your silence, you can cast Arcane Bolt to break it or wait until someone on your team breaks it. In addition, Linken's Sphere builders are usually squishy targets vulnerable to silences: 
Weaver, 
Queen of Pain, 
Morphling, Clinkz, etc. Don't forget that Ancient Seal also increases the magical damage these enemies take, along with silencing them.
Clinkz
* Heroes who rely on burst physical damage are affected by Lucky Shot's disarm: Terrorblade, Sven, Clinkz, 
Windranger, Alchemist, Dragon Knight, 
Legion Commander
Omniknight
* Heroes who cannot escape from Trample early might be easy first blood. Heroes like 
Witch Doctor and Omniknight should play very cautiously alone...
Omniknight
* Heroes that rely on slows or low-duration stuns have trouble catching Weaver: Omniknight, Lich.
Clinkz
* Heroes that excel at grouping up with their team very early will be able to take advantage of a Clinkz that tries to pick off heroes that are alone: Brewmaster, Dazzle, Tidehunter.
Clinkz
* Fragile carries with no reliable escaping mechanism can be bursted down in no time: Sniper, Drow Ranger, Clinkz
Omniknight
* 
Fortune's End's AoE dispel will remove Heavenly Grace and Guardian Angel.
Additional:
* Oracle can dispel Heavenly Grace (which he can also bait out with Fate's Edict).
* With Fortune's End, Oracle can dispel Guardian Angel in an area of effect.
Clinkz
* Heroes who can take advantage of Oracle's low mobility or catch him out of position, such as Clinkz and Anti-Mage, can easily pick him off.
Clinkz
* Heroes who build mana boosting items but have low mana regeneration are especially vulnerable against Mana Break and Mana Void: 
Timbersaw, 
Slark, 
Shadow Fiend, Clinkz, 
Bristleback Nyx Assassin, 
Magnus
Omniknight
* Heroes who can drain mana can make Omniknight useless after he uses one or two abilities: Lion, Anti-Mage, Nyx Assassin.
Clinkz
* Anti-Mage's 
Counterspell provides no protection against Clinkz's physical damage output.
* Clinkz can easily rush an 
Orchid Malevolence to prevent 
Blinking, although Anti-Mage can easily dispel it via 
Manta Style.
* Clinkz does heavy damage to towers, and can take map control away from Anti-Mage to limit the space he has to farm early game. If Clinkz is ahead he is capable of ending the game before Anti-Mage becomes a threat. He can also match Anti-Mage's ability to split push.
Clinkz
* Clinkz's high damage output and insane attack speed late-game can take Kunkka out of the fight before it begins.
* 
Burning Barrage and 
Searing Arrows together can kill allies easily even under Ghostship's buff.
* Skeleton Walk can allow Clinkz to make a quick escape after Kunkka's combo, or even avoid it all together.
Omniknight
* Guardian Angel makes allies immune to all physical damage, effectively causing Tidebringer to do no damage.
* Purification is a powerful, pure damaging heal that can save Omniknight's allies after Kunkka's large damage.
Clinkz
* Ember Spirit's 
Flame Guard provides no protection against Clinkz's physical damage output.
* Ember Spirit's low armor and health make him easy to kill quickly if a teammate can hold him down.
* If Clinkz has farmed an item that can disable, he can sneak up to and hunt down Ember Spirit while he farms or split pushes alone.
Omniknight
* The pure damage provided by Purification is a great addition for killing Ember Spirit, as well as a good way of saving teammates.
* Guardian Angel will temporarily save his allies from Sleight of Fist's physical damage, and Ember Spirit is not a hero that will get Orchid Malevolence to counter it.
Clinkz
* Searing Arrows makes Clinkz one of the hardest heroes for Clockwerk to lane against.
Omniknight
* Purification does great damage to Clockwerk when fighting an enemy inside Power Cogs.
* Due to Clockwerk's very low damage output, Omniknight will have more than enough time to Purification and Heavenly Grace any enemy hero Clockwerk initiates on.
* For the same reasons, Omniknight also makes a powerful ally for Clockwerk when the situation is reversed.
Clinkz
* Invisible heroes all have the element of surprise. Provided they deal enough damage, Sniper should be vanquished very quickly: Clinkz, Riki, 
Bounty Hunter.
Omniknight
* Being mostly a physical damage dealer, Sniper's effectiveness is greatly reduced by Omniknight's Guardian Angel.
* Omniknight's 
Degen Aura allows him to slow sniper and catch him. Sniper has to then use some escape item.
* Omniknight can also protect an ally from being finished off by Assassinate by using Purification and Repel which grants a massive strength boost.
Clinkz
* With 
Bloodthorn, Clinkz becomes a strong counter to heroes who rely on evasion and blind such as Windranger, Phantom Assassin, Troll Warlord and 
Keeper of the Light.
Omniknight
* Heroes who rely strongly on melee physical damage will fare badly against Omniknight's Guardian Angel: Phantom Assassin, 
Juggernaut, Dragon Knight, Lycan, Ursa, Troll Warlord
Clinkz
* Clinkz's Skeleton Walk allows him to easily sneak on Chen and bypass his creeps. It also allows him to escape from them.
* Clinkz can easily kill Chen's creeps with 
Death Pact and gain gold, health, damage and abilities from them when upgraded with Death Pact Steal creep abilities talent.
* Clinkz naturally loves buying Gleipnir, which allows him to easily root Chen and his creeps and to kill them more easily with Burning Barrage from 
Aghanim's Shard.
* Clinkz can kill Chen or any of his allies with his physical damage burst from 
Strafe, 
Tar Bomb and Burning Barrage from Aghanim's Shard before he can use Hand of God. Especially when Clinkz has Gleipnir and 
Daedalus. Clinkz can also buy Bloodthorn to prevent Chen from even trying to use Hand of God.
Clinkz
* Nature's Prophet is often by himself. Clinkz can use invisibility to hunt him down and kill him, although a Quelling Blade may be needed to cut through his 
Sprout. Orchid Malevolence may also be needed if 3-4 seconds are not enough time to kill him, as he can teleport away.
* Clinkz can match Nature's Prophet's ability to split push.
Clinkz
* Clinkz's item build often counters Hoodwink, including Black King Bar, 
Monkey King Bar, 
Heaven's Halberd, and 
Scythe of Vyse.
* Skeleton Walk can quickly escape Hoodwink abilities.
Omniknight
* Purification heals a teammate targeted by Reality Rift and heavily damages Chaos Knight and his illusions in the process.
* Guardian Angel blocks all of Chaos Knight's damage for a long duration.
Additional:
* 
Phantasms can be easily killed with Purification.
* Heavenly Grace dispels the stun from 
Chaos Bolt and the armor reduction from 
Reality Rift.
* Guardian Angel works well against Chaos Knight's overwhelming reliance on physical burst damage.
Omniknight
* Slark's dependence on Pounce and close range makes him very easy to hit with Purification and 
Hammer of Purity.
* Slark's damage, even with a high count of Essence Shift stacks, is easily negated by Omniknight's heals and Guardian Angel.
Omniknight
* Guardian Angel negates most of Gyrocopter's physical АоЕ damage.
* Heavenly Grace dispels Homing Missile stun.
Omniknight
* Guardian Angel protects allies from Death Ward's physical damage.
* Purification and Heavenly Grace will most likely save teammates from dying to Maledict.
Clinkz
* Heroes with high armor like Dragon Knight, or with abilities to cause attacks to miss like Phantom Assassin, Riki and Tinker will be hard to deal with, as Clinkz relies almost entirely on physical attacks.
Clinkz
* With Bloodthorn, Clinkz becomes a strong counter to heroes who rely on evasion and blind such as Windranger, Phantom Assassin, Troll Warlord and Keeper of the Light.
Omniknight
* Purification and Hammer of Purity can easily catch Phantom Assassin once she jumps with 
Phantom Strike in to attack.
* Heavenly Grace can be used to dispel slow from 
Stifling Dagger, and disables from the items Phantom Assassin relies on.
* Phantom Assassin depends entirely on physical attacks and her damage output is 100% physical. Therefore, since she has no any sources of magical damage output and hates going for items that deal magical damage like Dagon, Ethereal Blade and Revenant's Brooch, Guardian Angel will render her completely useless.
* Purification, Heavenly Grace and Guardian Angel can be used to save an allied hero before Phantom Assassin can finish them off with 
Coup De Grace.
Additional:
* Purification and Hammer of Purity can easily catch Phantom Assassin once she jumps with Phantom Strike in to attack.
* Heavenly Grace can be used to dispel slow from Stifling Dagger, and disables from the items Phantom Assassin relies on.
* Phantom Assassin depends entirely on physical attacks and her damage output is 100% physical. Therefore, since she has no any sources of magical damage output and hates going for items that deal magical damage like Dagon, Ethereal Blade and Revenant's Brooch, Guardian Angel will render her completely useless.
* Purification, Heavenly Grace and Guardian Angel can be used to save an allied hero before Phantom Assassin can finish them off with Coup De Grace.
Omniknight
* Guardian Angel nullifies the physical damage from Exorcism during teamfights. And when upgraded with Aghanim's Scepter, it also prevents Death Prophet from pushing towers. However, Death Prophet can partially counter this issue with 
Eul's Scepter of Divinity, a common item on Death Prophet.
* Heavenly Grace dispels 
Silence.
Additional:
* 
Exorcism's damage is blocked by Guardian Angel.
* Heavenly Grace can dispel Silence allies if Omniknight is able to cast it.
Clinkz
* Huskar's 
Berserker's Blood provides no protection against Clinkz's physical damage output.
* Huskar has no way to disrupt Clinkz's attacks and no way to kill Clinkz alone, as Clinkz can easily go invisible, teleport away, or even fight back.
* Clinkz will often build the items that counter Huskar and the items he usually builds. These include Black King Bar or Monkey King Bar for Heaven's Halberd, or a disable item like Scythe of Vyse or Bloodthorn to prevent him from using 
Inner Fire to disarm.
Omniknight
* Heroes with large magical AoE damage will fare well against Omniknight: Lich, Ancient Apparition, Jakiro, Disruptor.
Clinkz
* Heroes that can pick you off: Clinkz, Nyx Assassin, 
Puck, Riki.
Omniknight
* Purification allows Omniknight to keep a hero trapped in the Static Storm alive.
* Repel is a reliable source of immunity to the effects of Static Storm.
Clinkz
* Strafe, Tar Bomb and Burning Barrage from Aghanim's Shard allow Clinkz to quickly kill Io due to its low armor.
* Clinkz iz a hero that very often goes for Orchid Malevolence, and its upgrade Bloodthorn. Alternatively, Clinkz also loves to buy Gleipnir. And if Clinkz has both of them, he will be able to root and silence Io and prevent him from escaping with either 
Tether or 
Relocate.
Omniknight
* Heavenly Grace reduces Fireblast stun time and dispels Ignite.
* Purification can heal damaged heroes if needed.
Omniknight
* Guardian Angel completely negates all of Lycan's damage since Lycan mainly deals physical damage.
* Purification can also be a problem for Lycan, as Purification deals damage around the target, which poses a problem for him and his summons.
Omniknight
* Guardian Angel completely negates all physical damage, including 
Omnislash.
Additional:
* Omnislash (and 
Swiftslash) is blocked by Guardian Angel.
Omniknight
* Omniknight's healing prevents allies from dropping low enough for 
Culling Blade
* Heavenly Grace dispels 
Battle Hunger.
* Axe also tends to get close to allied heroes in order to damage them with his 
Counter Helix, which can easily be punished by Purification.
Clinkz
* 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.
Clinkz
* With Bloodthorn, Clinkz becomes a strong counter to heroes who rely on evasion and blind such as Windranger, Phantom Assassin, Troll Warlord and Keeper of the Light.
Omniknight
* 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.
Clinkz
* Heroes with a high degree of mobility and invisibility are hard to catch with Meat Hook: 
Ember Spirit, Riki, Clinkz, Queen of Pain.
Clinkz
* Due to Tiny's non-existent agility gain, high physical damage heroes are more effective against him (Clinkz, Templar Assassin, Ursa, Wraith King etc).
Omniknight
* 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.
Omniknight
* Heroes who possess abilities that can save targets from being killed by Reaper's Scythe: 
Abaddon, 
Bane, 
Outworld Destroyer, Shadow Demon, Omniknight, etc.
Clinkz
* Clinkz can use 
Burning Army in teamfights which will cause a problem for Alchemist.
Clinkz
* Heroes with invisibility and high mobility can jump on and focus down Earthshaker before he has a chance to initiate: Clinkz, Slark, 
Storm Spirit
Omniknight
* Heroes who rely strongly on melee physical damage will fare badly against Omniknight's Guardian Angel: Phantom Assassin, Juggernaut, Dragon Knight, Lycan, Ursa, Troll Warlord
Clinkz
* Spectre can instantly escape Burning Army or hunt Clinkz with 
Haunt.
* Spectre can catch up to him with 
Spectral Dagger, even if he uses Skeleton Walk.
* 
Desolate allows Spectre to hit Clinkz through Skeleton Walk.
* 
Dispersion makes Spectre tanky and also reflects some damage back to Clinkz.
Additional:
* Spectre can catch Clinkz with Spectral Dagger, even if he uses Skeleton Walk.
* Spectre can instantly reach a ratting Clinkz with Haunt.
* Desolate's damage will melt him quickly, as he's alone most of the time.
Clinkz
* Heroes with good escapes can usually outmaneuver and escape from Spectre: Slark, Clinkz, Weaver
Omniknight
* Global Guardian Angel will protect his allies from Spectre's Haunt, both when they are alone and in teamfights.
* Purification is a major problem for melee enemies, Spectre included, since they must be next to an enemy in order to attack. The AoE damage also allows Spectre to be singled out from her illusions.
* Degen Aura will prevent Spectre from chasing Omniknight, further exacerbated by her terrible mobility outside Haunt.
Clinkz
* With Bloodthorn, Clinkz becomes a strong counter to heroes who rely on evasion and blind such as Windranger, Phantom Assassin, Troll Warlord and Keeper of the Light.
Clinkz
* 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.
Omniknight
* Omniknight can dispel Hex or Shackles with Heavenly Grace. He can also heal teammates who you disabled. The same goes for Abaddon's 
Aphotic Shield.
Clinkz
* Heroes who rely on invisibility, such as Bounty Hunter, Clinkz, 
Mirana, Nyx Assassin and Riki, as they will be revealed if caught by Chronosphere.
Omniknight
* Guardian Angel can negate all the physical damage output during Chronosphere.
* When Faceless Void Time Walk's on top of an enemy it becomes a perfect target for Purification
Additional:
* Guardian Angel can negate all the physical damage output from Faceless Void during 
Chronosphere.
* If Faceless Void 
Time Walks on top of an ally Purification + Heavenly Grace can turn the fight around.
Clinkz
* Heroes with high armor like Dragon Knight, or with abilities to cause attacks to miss like Phantom Assassin, Riki and Tinker will be hard to deal with, as Clinkz relies almost entirely on physical attacks.
Additional:
* Smoke Cloud prevents the use of Death Pact, Searing Arrows and Skeleton Walk, so Clinkz can neither defend himself against Riki nor fight back effectively.
* It's hard to gank Riki as Clinkz has to find him first.
Omniknight
* Riki takes a lot of damage from Purification while ganking Omniknight's allies or himself.
* Heavenly Grace instantly purges the slow from Diffusal Blade, while also providing a large amount of survivability for his victim.
* Degen Aura can hinder Riki's positioning tactics and put a heavy toll on Riki's already poor movement speed.
* Omniknight can easily save his allies by using Guardian Angel in combat.
Omniknight
* Heroes who can harass Omniknight out of lane will keep him weak in the mid game: 
Viper, Venomancer, Clinkz.
Clinkz
* Clinkz does not have any passive abilities at all, making 
Nethertoxin nearly useless.
* Viper's 
Corrosive Skin provides no protection against Clinkz's physical damage output.
Omniknight
* Although Sven relies often on physical damage, an Aghanim's Scepter upgraded 
Storm Hammer can dispel Guardian Angel with its wide radius.
Omniknight
* Purification can heal allies while dealing pure damage to Sven.
* Heavenly Grace can remove Storm Hammer's debuff immediately or make it a very mediocre stun.
* Guardian Angel negates Sven's massive damage during God's Strength.
* It should also be noted Sven can remove Omniknight's active spells with Aghanim's Scepter.
Omniknight
* All of Omniknight's abilities are valuable for Rubick to 
Spell Steal, and Omniknight has no throwaway ability to cover his last used spell.
Clinkz
* Considering Rubick's abysmal armor, Rubick is a squishy target for Clinkz to gank on his own.
* None of his spells are useful except for Skeleton Walk.
* Clinkz usually builds Orchid Malevolence, which disables Rubick's ability to retaliate.
* Vast numbers of 
Sentry Wards are needed to deal with Clinkz because of Skeleton Walk, making it harder for Rubick to buy more expensive and more useful support items like 
Glimmer Cape or 
Mekansm.
Clinkz
* Heroes who cannot fight back during Arena of Blood in the early and mid game: Abaddon, Anti-Mage, 
Broodmother, Luna, Sniper, Troll Warlord, Weaver, Clinkz.
Omniknight
* Heroes that can save their allies can be a big problem for Mars: Dazzle, Omniknight.
Clinkz
* Heroes with high armor like Dragon Knight, or with abilities to cause attacks to miss like Phantom Assassin, Riki and Tinker will be hard to deal with, as Clinkz relies almost entirely on physical attacks.
Additional:
* The extra damage from Searing Arrows is largely blocked by Dragon Knight's armor.
* Clinkz has too low health to survive a gank.Getting stunned keeps him down long enough for a reaction.
* Breathe Fire reduces his damage, as he almost exclusively deals physical damage.
Omniknight
* Heroes who rely strongly on melee physical damage will fare badly against Omniknight's Guardian Angel: Phantom Assassin, Juggernaut, Dragon Knight, Lycan, Ursa, Troll Warlord
Clinkz
* Frostbite will reveal invisible heroes for its duration, making it a good tool against any such hero (Riki, Bounty Hunter, Weaver, or Clinkz for example), or as a soft counter to 
Shadow Blade, if it is used first. This can be an amazing tool to ensure that 
Dust of Appearance is used on the unit in question, and not wasted in not catching anything.
Clinkz
* Heroes who can easily harass Crystal Maiden out of lane in the early game (Clinkz, Viper) can prevent Crystal Maiden from being able to level effectively, and can ultimately slow down her level 6, 12, and 18 to a point where enemy carries already have items to address her ultimate.
Omniknight
* Heroes who can harass Omniknight out of lane will keep him weak in the mid game: Viper, Venomancer, Clinkz.
Clinkz
* Any hero that can outrange Plague Ward can neutralize them without putting themselves at risk of receiving Poison Sting: 
Arc Warden, 
Chen, Clinkz, Drow Ranger, Lina, Mirana, 
Nature's Prophet, Pugna and Sniper.
* Special mention to heroes that outrange Plague Ward after obtaining talents that increase attack range.
Omniknight
* Heroes with large magical AoE damage will fare well against Omniknight: Lich, Ancient Apparition, Jakiro, Disruptor.
Clinkz
* Ancient Apparition has no escape or reliable control and is very fragile, which makes him an easy target for anyone who can get on top of him, like Phantom Assassin or Clinkz.
Clinkz
* Possibly Clinkz's worst enemy. He has many tools to utterly destroy Clinkz.
* 
Charge of Darkness can be used on Clinkz if Spirit Breaker's team spots him anywhere. This charge will track his location through Skeleton Walk's invisibility and movement speed bonuses.
* When Spirit Breaker charges onto Clinkz, he can easily use Dust of Appearance to guarantee a reveal on him while stunned.
* All three of Spirit Breaker's spells help him and his team quickly close the gap to Clinkz even at the edge of his attack range or when running away with Skeleton Walk.
* Spirit Breaker's high strength and above average armor makes him able to endure Clinkz's onslaught, meanwhile Clinkz will be heavily threatened if Spirit Breaker procs a 
Greater Bash.
Additional:
* Once caught with dust, Clinkz could be locked down for a long time by Spirit Breaker and has nowhere to escape.
* Charge of Darkness provides shared vision over its target, showing Clinkz even when he is in Skeleton Walk.
Omniknight
* In the early game, Omniknight can look like an easy target for Spirit Breaker, but with Purification and Hammer of Purity, what could be an opportunity could quickly turn into disaster.
* Repel can be used to counter Charge of Darkness by minimizing the damage and lowering the stun duration with status resistance.
* Spirit Breaker's Greater Bash from all sources (Charge of Darkness or normal attacks) will deal no damage at all if Omniknight and his allies are protected with presence.
* Due to this, Spirit Breaker's damage will always be lower when targeting Omniknight.
Clinkz
* Skeleton Walk is not enough to outrun Bloodseeker, and is detected by Thirst.
* Because of his low health and high damage output, Clinkz will get obliterated by 
Blade Mail
Additional:
* 
Thirst reveals Clinkz if he tries to escape with Skeleton Walk with low health. It also allows Bloodseeker to match or exceed Clinkz's speed.
* 
Rupture negates the mobility provided by Skeleton Walk in any attempt to escape or reposition in fights.
* Bloodseeker can easily build items to counter Clinkz, including 
Talisman of Evasion upgrades, Blade Mail, and armor items.
Omniknight
* Guardian Angel's near invulnerability denies Bloodseeker the bonuses from Thirst, preventing him from gaining the upper hand in teamfights.
* Purification's pure damage makes it hard for Bloodseeker to pursue enemies, and prevents him from replenishing his health by finishing off enemies.
Omniknight
* Heroes under Guardian Angel can be still damaged from the pure damage of 
Black Hole and magical damage of 
Midnight Pulse.
Clinkz
* Despite Clinkz's fragility, his harassment in the early game can be devastating; as he can kite Enigma and his Eidolons and claim their bounty with Burning Barrage and Tar Bomb.
* Clinkz often goes for a disabling item like Bloodthorn or Gleipnir, which allows him to cancel Enigma's Black Hole until Enigma gets Black King Bar. Gleipnir can also root Enigma, preventing him from using 
Blink Dagger to escape from Clinkz.
* Even with Black King Bar, Clinkz can still easily kill Enigma as all of his abilities ingore spell immunity, and Enigma is a very easy target for Burning Barrage, which means Clinkz can solo Enigma at any stage of the game unless Clinkz is caught in Black Hole.
Clinkz
* Clinkz has no stun and likes to keep his distance from targets, making Marksmanship very deadly.
* Clinkz also has low health, making him a perfect hero to initiate onto with Gust.
* Gust can also prevent Clinkz from using Burning Barrage.
Omniknight
* Repel can be used to dispel 
Gust on the allies affected by it.
* In team fights, Guardian Angel renders Drow Ranger's physical damage useless, and Drow Ranger has no way to purge it. And to make thing worse, Drow Ranger is not a common 
Nullifier wielder to counter this problem at all.
Clinkz
* 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.
Omniknight
* Heroes with strong dispels can dispel Bane's disables from their allies: Oracle, Legion Commander, Omniknight.
Clinkz
* 
Cold Embrace can heal herself or an ally, as well as protecting them from Clinkz's physical attacks and wasting his mana if Searing Arrows is on autocast.
* 
Winter's Curse allows Winter Wyvern to turn Clinkz's high damage and high attack speed against his allies, or take advantage of Clinkz's fragility if he can't use Skeleton Walk.
Omniknight
* Guardian Angel completely counters Winter's Curse if Omniknight is able to cast it.
Additional:
* Guardian Angel completely counters Winter's Curse, allowing his team to survive Winter Wyvern's initiation.
* Purification and Repel are very useful against Arctic Burn, Splinter Blast and Winter's Curse as well.
Clinkz
* Searing Arrows and Clinkz physical damage items are almost suicidal when used on Legion Commander, as it invites an instant Duel and Legion Commander herself is a natural Blade Mail carrier.
* Duel locks down Clinkz for a long duration, preventing him from escaping with Skeleton Walk.
Omniknight
* Purification prevents Legion Commander from killing her target, and will always hit her during Duels.
* Guardian Angel completely wastes Duel's duration and can save an ally across the map when upgraded with Aghanim's Scepter.
Additional:
* Both Guardian Angel and Purification are perfect counters against 
Duel.
Clinkz
* Invisibility reliant heroes: Heroes with invisibility abilities or those that have invested into invisibility items are hindered by Bounty Hunter's Track. Few examples of such heroes are:Clinkz, Riki, Treant Protector, etc.
Additional:
* 
Track reveals Clinkz if he tries to escape with Skeleton Walk, allowing Bounty Hunter to gain lots of gold if he kills Clinkz.
* 
Jinada with physical damage items can quickly kill Clinkz due to his low health.
Omniknight
* Omniknight with Heavenly Grace
* 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.
Clinkz
* Lina's damage burst can quickly kill Clinkz before he saves them with
Skeleton Walk.
Burning Army easily in all stages of the game.
* Fiery Soul attack speed bonus removes
Omniknight
*
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.
