Keeper of the Light
* 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.
Hoodwink
* 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.
Keeper of the Light
* Heroes with teleports to escape Solar Blind and Will-O-Wisp: Phantom Assassin, 
Puck, 
Queen of Pain, 
Storm Spirit
Hoodwink
* Storm Spirit can easily make his way to Hoodwink with his ultimate 
Ball lightning, and coupled with Hoodwink's low health and magic resistance, she can be nuked easily.
* Additionally, Ball lightning can destroy a small amount of trees in its destination. Combined with Storm Spirit's frequent usage of his ultimate, he can clear out an area of trees while simultaneously attacking him and dodging incoming attacks.
Keeper of the Light
* Heroes with hastes: 
Dark Seer, 
Lycan
Hoodwink
* With 
Normal Punch from 
Aghanim's Scepter, Dark Seer can gain an advantage against heroes who rely on evasion as Normal Punch has true strike: Phantom Assassin, Windranger, 
Hoodwink.
Keeper of the Light
* Keeper of the Light's Aghanim's Scepter upgrade loses much of its power, due to Night Stalker being able to reduce the duration of daytime by a lot.
Additional:
* 
Crippling Fear prevents Keeper of the Light from using his spells to keep his team alive during team-fights.
* 
Dark Ascension is very strong against Keeper of the Light, as it allows Night Stalker to jump the backline and quickly kill the squishy Ezalor, especially when combined with the slow from 
Void.
Hoodwink
* Treant can give chase should Hoodwink attempt to 
Scurry away, and 
Nature's Grasp can slow her down so Treant Protector's teammates can pin Hoodwink down.
Hoodwink
* 
Nether Swap can forcibly reposition 
Sharpshooter.
Keeper of the Light
* 
Blood Rite makes Ezalor chose between getting off Illuminate or getting silenced for a while, as Illuminate is a channeled ability.
* Blood Rite's silence can completely take Ezalor out of a teamfight, as he relies on his abilities to be useful.
* Keeper of the Light's only mobility source, his high movement speed (via his high base movement speed and through spirit form), is entirely countered by 
Rupture.
Hoodwink
* 
Chaotic Offering's vast area-effect can destroy trees and stun Hoodwink.
* 
Upheaval makes retreating with Scurry difficult.
Keeper of the Light
* Being a cast-oriented hero, Ezalor will suffer from all of Silencer's abilities.
* 
Global Silence is a guaranteed lengthy silence which will render Ezalor useless in a teamfight.
* 
Arcane Curse and 
Last Word are good against any caster, since they are extremely potent.
* However, it should be worth mentioning that a smart Ezalor will buy Eul's Scepter of Divinity to dispel Silencer's abilities. Combined with the level 20 talent (Chakra Magic applies a basic dispel), Ezalor can purge Silencer's abilities off allies and himself alike.
Hoodwink
* Powershot can destroy the trees to prevent Scurry's passive as well as end 
Bushwhack prematurely or prevent it completely.
* 
Acorn Shot creates a tree for Windranger to get an easy Shackleshot off.
* Acorn Shot does not grant True Strike, thus making it easy for Windranger to evade it with Windrun.
* Shackleshot stuns Hoodwink for a lengthy duration due to her often reliance on positioning with trees.

Hoodwink
* Due to Hoodwink's low health and Zeus's high magic damage from 
Arc Lightning, 
Lightning Bolt and 
Static Field as well as global abilities from 
Thundergod's Wrath and 
Nimbus, he can easily kill her throughout the game and also reveal where Hoodwink is positioned or when she's in trees.
Keeper of the Light
* Pugna easily copes on the line with the Keeper of the Light push with his 
Nether Blast, and in addition to 
Nether Ward, the Keeper of the Light is not able to throw 
Illuminate on creeps for a long time, so Pugna earns more gold and a level on the line

Hoodwink
* Timbersaw’s reliance on nearby trees means he’ll usually be close to Hoodwink.
* More significantly, Timbersaw's tree destroying abilities cut off Hoodwink's escape options, passive and easily foil Acorn Shot or Bushwhack combos.
* While channeling Sharpshooter, Timbersaw can simply sit his 
Chakram on top of her and unleash his full combo, forcing her to cancel and disengage.
* 
Timber Chain can be used to dodge Sharpshooter.
Keeper of the Light
* Heroes with dispels: 
Legion Commander, 
Oracle, 
Slark, 
Phantom Lancer
Hoodwink
* Slark's 
Pounce can be used to dodge Hoodwink's abilities or lock her down.
* 
Shadow Dance makes Slark unhittable from Acorn Shot.
* 
Dark Pact removes all slows from Hoodwink's abilities.
* Hoodwink's already low health output is a great target for Slark's 
Essence Shift.
Keeper of the Light
* Melee carries during the laning phase: 
Sven, Slark
Hoodwink
* 
Remote Mines are frequently placed in trees, and can thus kill an unwary Hoodwink should she Scurry away due to her low HP pool.
* 
Blast Off! can clear out trees, denying the tactical advantages from Scurry.
Keeper of the Light
* Heroes with dispels: Legion Commander, Oracle, Slark, Phantom Lancer
Keeper of the Light
* 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 allows him to be immune to all of Ezalor's abilities. Also, the increased movement speed combined with the slow from 
Ghoul Frenzy and the squishy nature of Ezalor allows Lifestealer to take him down very quickly.
Hoodwink

Tinker
Keeper of the Light
* 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.
Keeper of the Light
* Keeper of the Light's Blinding Light makes Juggernaut miss his attacks. However, it can be dispelled easily with Blade Fury.
Keeper of the Light
* Being an intelligence caster hero, Ezalor usually has a high mana pool and low health and armor, making him a prime target for 
Mana Void
* Ezalor's Illuminate damage and Solar Bind's magic resistance reduction are greatly reduced thanks to 
Counterspell. Counterspell can also block and reflect Solar Bind if timed properly.
* Anti-Mage usually is not hampered by Solar Bind or Will-O-Wisp thanks to 
Blink.
* However, despite all of this, if Keeper of the Light is played carefully and tops off his team's mana at all times, Anti Mage will not be able to get off a good Mana Void.
* By the same token once Keeper of the Light gets a 
Octarine Core, he can spam Charka Magic to keep his own mana ful
Keeper of the Light
* Keeper of the Light can stall pushes with Illuminate. This makes him strong against pushing heroes: 
Terrorblade 
Naga siren 
Nature's Prophet and 
Anti-Mage
Keeper of the Light
* Blinding Light can knock Monkey King outside of his ultimate, Wukong's Command and can blind him.
* Will-O-Wisp will stun Monkey King from Tree Dance by destroying his tree.
Additional:
* Blinding Light can easily push Monkey King out of Wukong's Command, as well as blinding him.
* Monkey King is vulnerable to burst damage, 
Solar Bind makes him more so
* However, Keeper of the Light can be easily ganked by Monkey King during early-mid game stage.

* Sharpshooter provides flying vision along the cast indicator while charging, which can be used to scout the trees for Monkey King.
Keeper of the Light
* Heroes with summons/illusions/neutral creep armies: 
Beastmaster, 
Chen, Naga Siren
Hoodwink
* Heroes with evasion will cause Chen and his creeps to struggle in attacking them and will waste much of Penitence's power: Phantom Assassin, Windranger, Hoodwink.
Keeper of the Light
* Keeper of the Light can stall pushes with Illuminate. This makes him strong against pushing heroes: Terrorblade Naga siren Nature's Prophet and Anti-Mage
Hoodwink

Nihilism from Aghanim's Scepter,

* Because Phantom Assassin is often reliant on critical strikes, Hoodwink can have enough time to simply move near a tree and escape with Scurry.
Keeper of the Light
