Razor
* 
Life Break along with 
Burning Spear can quickly kill Razor before Static Link steals enough damage for Razor to take down Huskar.
* 
Berserker's Blood can make stealing Huskar's damage and using it against him somewhat dangerous, as Huskar will be able to inflict more and more Burning Spears rapidly.
Keeper of the Light
* Vulnerable spellcasters with no escape mechanisms are easy targets for Huskar: 
Lich, 
Crystal Maiden, 
Silencer, 
Keeper of the Light, 
Venomancer, etc.
Razor
* 
Blink can easily break Static Link and 
Counterspell reflects Static Link on Razor.
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
Razor
* Any hero with teleport abilities (e.g. 
Ember Spirit, 
Storm Spirit) can easily break Static Link.
Additional:
* Ball Lightning breaks 
Static Link.
* Razor has no way to catch a slippery Storm Spirit.
Keeper of the Light
* Heroes with teleports to escape Solar Blind and Will-O-Wisp: 
Phantom Assassin, 
Puck, 
Queen of Pain, Storm Spirit

Sniper or 
Razor.
Keeper of the Light
* Heroes with dispels: 
Legion Commander, 
Oracle, 
Slark, 
Phantom Lancer
Razor
* 
Dark Seer can increase the movement speed of allies with 
Surge, breaking Static Link.
Keeper of the Light
* Heroes with hastes: Dark Seer, 
Lycan
Razor
* His increased attack range makes it very hard to get close enough for Static Link, Eye of the Storm and Razor's own attacks.
* 
Headshot procs will slow Razor heavily regardless of Storm Surge, as it will knock him back for a brief duration.
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
Additional:

Razor
* Centaur can use 
Stampede to break Static Link. It also prevents Razor from chasing Centaur Warruner or his teammates with Eye of the Storm, and Plasma Field's slow will do nothing to slow them down.
Razor
* 
Spell Steal can easily steal abilities from Razor. Since Rubick get steal Static Link, Rubick can recover of his stolen damage, or simply steal Razor's own
Razor
* 
Boulder Smash's and 
Geomagnetic Grip's (upgraded with 
Aghanim's Scepter) repositioning and disables make it very difficult for Razor to keep enemies within range of Static Link and Eye of the Storm.
Razor
* Outworld Destroyer doesn't care if Razor steals his damage because he does most of his damage through 
Arcane Orb.
* 
Astral Imprisonment can prevent Razor from using the stolen damage from Static Link or chasing with Eye of the Storm.
* 
Sanity's Eclipse will do a ton of damage to Razor due to his low mana pool.
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.
Razor
* Necrophos usually doesn't build itmes that give attack damage, minimalizing effects of Static Link.
* He can use 
Ghost Shroud to prevent Razor from attacking him with the stolen damage from Static Link.
* Razor is somewhat vulnerable to magical damage, and 
Reaper's Scythe prevents him from escaping with his high movement speed when things get dangerous.
Razor
* 
Shukuchi can break Static Link with little trouble.
* 
Time Lapse can easily be used to avoid damage from Plasma Field and can recover the damage done from Static Link and Eye of the Storm.
* Eye of the Storm can't kill bugs from 
The Swarm.
Razor
* 
Pounce can easily break Static Link, making it less powerful against him.
* Slark is one of the few heroes who can man fight a Razor, because of 
Essence Shift.
* 
Shadow Dance can prevent Razor from killing him and may provide an opportunity to kill Razor due to it preventing Razor from attacking Slark.
Keeper of the Light
* Heroes with dispels: Legion Commander, Oracle, Slark, Phantom Lancer
Keeper of the Light
* Melee carries during the laning phase: 
Sven, Slark
Razor
* Morphling can break Static Link with Waveform. Alternatively, Morphling can Morph into Razor and use the same ability against him.
* Morphling's high armor makes 
Eye Of The Storm mostly ineffective, enabling Morphling to fight Razor for longer.
* Razor has no disables, enabling Morphling to avoid his abilities as needed.
Additional:
* Static Link is almost completely useless against Morphling, as he is able to quickly break it off with 
Waveform or turn into Razor himself with 
Morph and recover all of his stolen damage, or simply steal Razor's own.
Razor
* Razor has no way to deal with Chaos Knight's multiple illusions from 
Phantasm.
Keeper of the Light
* Jakiro's reliance on his abilities can cause struggles for heroes who rely on evasion or blinds to get upper hand: Phantom Assassin, 
Windranger, 
Riki, 
Troll Warlord, Keeper of the Light.
Keeper of the Light
* Squishy heroes, usually supports, like 
Lion, 
Ancient Apparition, Keeper of the Light etc can die quickly to Tiny's magic burst.

Keeper of the Light
* Heroes with channeling abilities: 
Enigma, 
Witch Doctor, Crystal Maiden.
Keeper of the Light
* Heroes with silences: Puck, 
Doom, Riki.
Razor
* Heroes who rely on abilities to deal damage (e.g. 
Timbersaw, 
Tinker) can fight a Razor even after Static Link.
Razor
* Heroes who rely on abilities to deal damage (e.g. Timbersaw, Tinker) can fight a Razor even after Static Link.
Additional:
* Razor deals mostly physical damage towards the later game, and Timbersaw is also very mobile, making him a difficult kill to earn.
* Timbersaw rarely resorts to attacks, thus does not suffer when his damage is stolen with Static Link.
Razor
* Any hero with teleport abilities (e.g. Ember Spirit, Storm Spirit) can easily break Static Link.
Keeper of the Light
* Heroes with channeling abilities: Enigma, Witch Doctor, Crystal Maiden.
Keeper of the Light
* 
Finger of Death can instantly shred many targets, especially fragile Heroes like Keeper of the Light, Ancient Apparition or 
Bounty Hunter.
Keeper of the Light
* Heroes that can jump and kill him: 
Meepo, 
Clinkz, 
Templar Assassin
Keeper of the Light
* Large area-of-effect with delay or require channeling: Enigma, Crystal Maiden, 
Invoker, 
Shadow Fiend, 
Pugna, Keeper of the Light, 
Dawnbreaker.
Additional:
* 
Spiked Carapace can be used to reflect Illuminate damage and stun Keeper of the Light.
* 
Vendetta allows Nyx Assassin to follow Keeper of the Light around if he tries to split-push.
* Keeper of the Light is very squishy and will very quickly die to Vendetta and it's followup abilities.
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.
Razor
* Heroes with stronger lane presence that can threaten to kill him: 
Batrider, 
Juggernaut, 
Ursa, 
Monkey King, Razor.
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.
Razor
* Heroes that rely on right-clicks will find themselves unable to damage opponents seriously after being affected by Static Link, like Sven, 
Bloodseeker, and Juggernaut.
Razor
* Static Link can steal the bonus damage from 
Jingu Mastery and reduce the physical damage from 
Boundless Strike. It also reduces 
Wukong's Command's damage if it's used after stealing damage via Static Link.
* Static Link will give Razor shared vision on Monkey King if he tries to escape using 
Tree Dance or 
Mischief.
* Plasma Field can prevent Monkey King from using Tree Dance and Mischief.
* Eye of the Storm will remove the armor buff from Wukong's Command, as well as hitting Monkey King during Mischief.
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.
Razor
* Razor's 
Plasma Field and the passive from Eye of the Storm can damage and clear Chen's creeps.
* Chen has no escape mechanisms, making him easy prey for Static Link, which can also minimalize effects of 
Penitence.
* Eye of the Storm will rapidly strike Chen's creeps around Razor.
Keeper of the Light
* Heroes with summons/illusions/neutral creep armies: 
Beastmaster, 
Chen, Naga Siren
Razor
* Plasma Field and Eye of the Storm can help Razor clear waves of Terrorblade's illusions.
* Static Link can significantly weakens Terrorblade's damage, even during 
Metamorphosis, making Terrorblade's attacks tickle while strengthening Razor's attack damage. Terrorblade also lacks escape mechanisms, making Terrorblade a good target for Static Link and forcing Terrorblade to buy 
Linken's Sphere.
* 
Storm Surge makes it difficult for Terrorblade to catch Razor, and when upgraded with 
Aghanim's Shard, it can also deal damage to Terrorblade and his illusions.
* Eye of the Storm can rapidly weaken Terrorblade's armor, which combined with Terrorblade's low health and strength gain can almost completely discourage Terrorblade from even being present in teamfights.
* Static Link and Eye of the Storm cannot be dispelled neither with 
Manta Style nor blocked by 
Black King Bar, which can put Terrorblade in a big disadvantage against Razor.
* However, Razor's lack of disables makes it difficult for him to burst down Terrorblade before he can use 
Sunder unless Razor has either Black King Bar or Linken's Sphere to protect himself against it.
Additional:

* However, Razor's lack of disables can make it difficult for him to burst down Terrorblade before he can use Sunder unless Razor has either Black King Bar or Linken's Sphere to protect himself against it.
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
Razor
* Plasma Field can slow Magnus during Skewer, and when combined with Eye of the Storm, will potentially disable his Blink Dagger, preventing him from initiating.
* Static Link drains the bonus damage from Empower. However, it can be broken by Skewer and/or Force Staff.
* Storm Surge gives Razor and his allies high mobility needed to avoid Shockwave & Reverse Polarity.
Keeper of the Light
* 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,

Zeus, 
Shadow Shaman, 
Phoenix, Razor, 
Huskar, Batrider, 
Kunkka, 
Tidehunter, 
Wraith King, 
Sand King, 
Medusa, Dawnbreaker.
Razor
* With Static Link, Razor can effectively make Medusa useless in teamfights by reducing her main damage output. It can, however, be blocked by a Linken's Sphere.
* Plasma Field allows Razor to get on top of Medusa, slowing her already slow movement speed to a mere crawl.
* Eye of the Storm capitilizes on Medusa's low armor and causes her to be very vulnerable, even through 
Mana Shield.
Keeper of the Light
* Heroes with extremely slow movement speed will cripple against Solar Bind: Medusa, 
Viper
Additional:
* 
Will-O-Wisp will keep Medusa busy after she got hit by Blinding Light.
Razor
* 
Nether Strike can't remove Static Link and reduces Spirit Breaker's physical damage output.
* Eye of the Storm melts Spirit Breaker's armor, and makes him much less tanky.
Additional:
* Plasma Field can slow Spirit Breaker and reduce damage from Greater Bash.
* Static Link drains damage bonus from Greater Bash, and it cannot be removed by Nether Strike.
* Storm Surge will proc on Spirit Breaker every time he attacks Razor or if he uses Charge of Darkness on Razor, damaging him and alerting Razor to Spirit Breaker's incoming ganks, no matter how far Spirit Breaker is from Razor.
* Eye of the Storm can rapidly reduce Spirit Breaker's armor, making him much less durable, especially in teamfights.
Keeper of the Light
* Heroes that punish mobile heroes: Bloodseeker, Keeper of the Light, Kunkka, 
Disruptor.
Razor
* Heroes that rely on right-clicks will find themselves unable to damage opponents seriously after being affected by Static Link, like Sven, Bloodseeker, and Juggernaut.
Additional:
* Static Link saps Sven's insane attack damage, and goes through Black King Bar.
Keeper of the Light
* Keeper of the Light's AoE blind can keep Sven from landing hits.
Razor
* Static Link drains Tusk's base damage, and it also reduces the critical damage output from 
Walrus PUNCH!.
* Plasma Field and Eye of the Storm allow Razor to chase Tusk after he uses Snowball.
Razor
* Static Link is effective against Troll Warlord, as he mainly relies on attack speed more so than damage.
* Static Link is even more effective if Troll Warlord used 
Battle Trance, as he has no way to break the link.
Additional:
* Static Link can drain most or all of Troll Warlord's damage, making him useless in a teamfight or unable to last hit in lane. This is especially effective during Battle Trance, because Troll has no option to cancel the link.
* Storm Surge allows Razor to chase after or run away from Troll Warlord while doing damage with Eye of the Storm.
Razor
* Static Link weakens Drow Ranger's attack damage while strengthening Razor's attack damage.
* Plasma Field & Storm Surge keeps Razor close to Drow Ranger, continuously disabling Marksmanship.
Razor
* Static Link drains the damage bonus from Enchant Totem, until he purchase Aghanim's Scepter or 
Force Staff to break it.
* Storm Surge with Razor's high mobility items can easily avoid all of Earthshaker abilities.
* Plasma Field & Eye of the Storm prevents Earthshaker escaping from 
Blink Dagger.
Additional:
* Static Link drains Earthshaker's bonus damage from 
Enchant Totem until he purchases an Aghanim's Scepter or Force Staff to break it.
* Eye of the Storm and Plasma Field can disable Earthshaker's Blink Dagger, preventing him from initiating or re-initiating.
Razor
* Alchemist's reliance on fast attack speed to do single-target damage makes him vulnerable to Static Link. It also goes through Black King Bar, which is a standard item on Alchemist.
* Eye of the Storm is great against high health strength heroes as it reduces their survivability to physical damage.
* Razor has early lane push to counter 
Acid Spray.
Razor
* Static Link can steal Shadow Fiend's high physical damage output from 
Necromastery, lowering his damage output, and Static Link cannot be prevented by Black King Bar.
* Plasma Field and Eye of the Storm can melt down Shadow Fiend easily, due to his low health.
Keeper of the Light
* Illuminate clears Beastmaster's summons and is effective against his push.
Razor
* Static Link can lower the damage output from 
Focus Fire.
* Eye of the Storm strikes cannot miss, even if 
Windrun is active.

* Eye of the Storm strikes cannot miss, even if Windrun is active.
Razor
* Eye of the Storm melts Bristleback's armor, and makes him much less tanky.
* Static Link can completely drain Bristleback's bonus damage from 
Warpath.
Additional:
* Eye of the Storm melts Bristleback's armor, and makes him much less tanky.
* Static Link can completely drain Bristleback's bonus damage from Warpath.
* Storm Surge allows Razor to outdistance Bristleback, even with a few stacks of Viscous Nasal Goo on him. Also, if Razor has his Shard, it will deal full damage to Bristleback every time he uses Viscous Nasal Goo (as Bristleback will face him to cast it).
Keeper of the Light
* Illuminate wipes out Broodmother's spiders and prevents her from pushing the lane. It also gives vision to reveal where broodmother is hiding in the trees.
Razor
* Plasma Field can spot an Ursa sneaking into Roshan's pit
* Static Link has a 800 link break distance, meaning Razor can stay close enough to drain Ursa' damage, but not too close to get attacked
* Static Link cannot be dispelled by 
Enrage
* With Storm Surge, Razor will usually be faster than Ursa in most cases
* Eye of the Storm melts through Ursa's armor
Razor
* Static Link greatly reduces Underlord's attack damage, while benefits Razor himself, even when in 
Atrophy Aura's range.
* Underlord is a slow and low mobility hero, and cannot outrun Razor's high movement speed, easily for Razor to absorb his damage with Static Link to the maximum and burst him down from the bonus damages, combine with the armor reduction from Eye of the Storm.
* However, Razor has no way of preventing enemies to escape with 
Fiend's Gate. And his only way to counter this is by buying disabling items.
Keeper of the Light
* Heroes with teleports to escape Solar Blind and Will-O-Wisp: Phantom Assassin, Puck, Queen of Pain, Storm Spirit
Razor
* Static Link can lower the damage output from 
Coup de Grace procs, hindering Phantom Assassin's main source of damage.
* Eye of the Storm strikes cannot be evaded by 
Blur.
* Both Static Link and Eye of the Storm pierces spell immunity, as Phantom Assassin is often reliant on Black King Bar.
Additional:
* Static Link can lower the damage output from Coup de Grace procs, hindering Phantom Assassin's main source of damage. And Phantom Assassin is not a common Linken's Sphere wielder to counter this problem.
* Eye of the Storm strikes cannot be evaded by Blur.
* Both Static Link and Eye of the Storm pierces spell immunity, as Phantom Assassin is often reliant on Black King Bar.
Keeper of the Light
* Heroes which rely exclusively on right clicks will struggle somewhat against Blinding Light: Phantom Assassin, Wraith King, Medusa
Razor
* Heroes who relies on high armor such as 
Dragon Knight, Tidehunter, and 
Pudge can be melted by Eye of the Storm.
Additional:
* Kraken Shell's dispel does not restore damage stolen by Static Link, and the stolen damage easily offsets Anchor Smash's damage reduction. Razor can keep attacking Tidehunter from afar, denying his chance to use Anchor Smash.
* Eye of the Storm melts Tidehunter's armor and makes him much less tanky.
* Razor can chase Tidehunter by himself without relying on actual crowd control ability, so the strong dispel from Kraken Shell is less useful.
Razor
* Anti-Tank heroes like: Razor, 
Necrophos, 
Undying.
Keeper of the Light
* Certain heroes can mess up with Pangolier's positioning and timing (especially if he intends to use Rolling Thunder during combat): 
Vengeful Spirit, Keeper of the Light, Huskar, Dark Seer
Keeper of the Light
* Heroes that have AoE damage: Lina, Keeper of the Light, Timbersaw, 
Leshrac, 
Bristleback, 
Axe.
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
Razor
* Heroes that reduce the damage that Marci can deal during her ultimate, like Razor, Rubick, 
Bane, Dragon Knight and 
Underlord.
Keeper of the Light
* 
Press the Attack can dispel Blinding Light or Solar Bind from a hero.
* 
Duel can be used to instantly take Keeper of the Light out of a team-fight.
Razor
* Static Link drains Legion Commander's accumulated damage, effectively neutralizing her overall primary advantage, and prevents her from winning Duels.
* Storm Surge's movement speed buff makes Razor and his allies harder to catch and initiate.
* Eye of the Storm, if used beforehand, will always hit Legion Commander during Duels, due to her forced proximity. This drastically lowers her survivability during Duel.
Keeper of the Light
* Heroes with abilities that blind or cause Legion Commander to miss will prevent her from winning Duels: 
Arc Warden, Keeper of the Light, Riki, Tinker
Razor
* Heroes who relies on high armor such as Dragon Knight, Tidehunter, and Pudge can be melted by Eye of the Storm.
Additional:
* Static Link saps Dragon Knight of his already low base damage, making him even more useless in a fight if he gets kited.
* Storm Surge makes Razor much faster than Dragon Knight, and hard to catch.
* Eye of the Storm melts Dragon Knight's armor and bypasses Black King Bar, his core item.
Keeper of the Light
* Heroes which rely exclusively on right clicks will struggle somewhat against Blinding Light: Phantom Assassin, Wraith King, Medusa
Keeper of the Light
* Heroes with dispels: Legion Commander, Oracle, Slark, Phantom Lancer
Razor
* Plasma Field can destroy Phantom Lancer's illusions or damage them heavily.
* Static Link cannot be broken even with Doppelganger, serving as a marker for the real Phantom Lancer.
* Storm Surge gives Razor's high mobility to chase down Phantom Lancer making Spirit Lance and 
Diffusal Blade slow useless.
* Eye of the Storm along with Aghanim's Scepter can quickly reduce Phantom Lancer's armor.
Additional:
* Plasma Field and Eye of the Storm clears most of Phantom Lancer's illusions.
* Static Link is not dispelled by 
Doppelganger or Manta Style which can be used to mark the real Phantom Lancer while also draining his base damage.
* Razor's high mobility with Storm Surge makes it hard for Phantom Lancer to chase down with 
Phantom Rush. When upgraded with Aghanim's Shard, it makes a quick work of his illusions.
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.
Razor
* Static Link cannot be dispelled by Rage or 
Infest, so Razor will be able to track Lifestealer down during an attempted escape.
* Storm Surge makes it hard for Lifestealer to catch Razor.
* Static Link can stop 
Open Wounds from getting any additional lifesteal, but keep in mind Lifestealer can still utilize 
Feast.
* Eye of the Storm penetrates the spell immunity of Rage.
Additional:
* Razor's highly mobile nature allows him to control Lifestealer from a distance. As well, Lifestealer is already slow in comparison due to his lack of disables and move speed. Lifestealer is also an ideal target for Static Link, for its ability to pierce magic immunity and damage steal, which can render Lifestealer's Feast useless.
* Plasma Field can slow Lifestealer from a distance and force him to cast Rage too early.
* Eye of the Storm pierces magic immunity, deals physical damage, and reduces armor, allowing Razor to easily stand up to Lifestealer.
Keeper of the Light
* Heroes with channeling abilities: Enigma, Witch Doctor, Crystal Maiden.
Keeper of the Light
* Illuminate can wipe the pushing Eidolons in a lane with ease, diminishing Enigma's laning presence by a lot.
* Solar Bind will severely slow down Enigma and make him more vulnerable to magical damage more he moves for it's duration.
* However, Keeper of the Light does not have any way to cancel 
Black Hole outside from Will-O-Wisp provided by Aghanim's Scepter.
Keeper of the Light
* Heroes with silences: Puck, Doom, Riki.
Razor
* Static Link drains away Riki's damage while keeping his location revealed for its duration, allowing his team to accurately land detection or area-of-effect skills.
* Storm Surge procs on invisible heroes, making him aware of Riki's presence near him.
Razor
* Time Walk can break Static Link very quickly, preventing Razor from building up to attack damage.
Razor
* Heroes who can proc their respective passives while inside Chronosphere can still be a problem for Darkterror: Axe, 
Abaddon, Razor...
Keeper of the Light
* Any hero that can nullify effects of Chronosphere: (Keeper of the Light with Aghanim's Scepter during daytime, 
Winter Wyvern), banishing him or Faceless Void (
Outworld Destroyer, 
Shadow Demon, 
Earth Spirit with Aghanim's Scepter) or protecting him in other ways (
Dazzle, Oracle, Abaddon) can greatly limit Chronosphere's potential.
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.
Razor
* Heroes that rely on right-clicks will find themselves unable to damage opponents seriously after being affected by Static Link, like Sven, Bloodseeker, and Juggernaut.
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
* Low health spellcasters: Lina, Witch Doctor, Tinker, Keeper of the Light, all rely heavily on their spells and are fragile heroes. They all also have avoidable spells, allowing Puck to get to them and quickly burst them down.
Keeper of the Light
* Heroes who are strong against mobile heroes: Disruptor, Bloodseeker, Kunkka, Keeper of the Light.
Keeper of the Light
* Heroes with hastes: Dark Seer, Lycan

* Keeper of the Light has a blind, which causes Lycan to miss his attacks.
Keeper of the Light
* Heroes that can jump and kill him: Meepo, Clinkz, Templar Assassin
Razor
* Templar Assassin's 
Refraction will easily be removed by Eye of the Storm, and Static Link reveals Templar Assassin hiding with 
Meld and drain the bonus damage from Refraction.
Additional:
* Razor's Eye of the Storm damage-over-time easily wear off Refraction charges, allowing Templar Assassin to be damaged.
* Static Link empties Templar Assassin's damage output even with the bonus from Refraction, and will keep doing that even if the Razor cannot see her during Meld.
* Plasma Field can easily strike her during Meld.
Razor
* Viper's 
Poison Attack and 
Viper Strike that can slow Razor, and is one of the few heroes that can keep him immobile.
* Altogether, Viper's skills reduce Razor's attack speed, heavily reducing the benefit of the damage drain from Static Link.
Additional:
* Storm Surge is counteracted by Viper Strike, leaving Razor without his extra movement speed.
* Static Link's damage drain doesn't bother Viper a lot as most of his early to mid game damage is magical.
Keeper of the Light
* The Keeper of the Light easily farms on the line against the Viper, due to the fact that it has a long-range Illuminate, and the Viper, in turn, cannot use its advantage of dominance on the center line, due to the fact that it does not reach the Keeper of the Light
Additional:
* The Keeper of the Light easily farms on the line against the Viper, due to the fact that it has a long-range Illuminate, and the Viper, in turn, cannot use its advantage of dominance on the center line, due to the fact that it does not reach the Keeper of the Light
Razor
*
Blink can instantly break Static Link, making it useless against her.
* Queen of Pain doesn't fully rely on her physical attack damage, so she can still fight after being hit with Static Link.
Keeper of the Light
* Heroes with teleports to escape Solar Blind and Will-O-Wisp:
Phantom Assassin, 
Puck, 
Queen of Pain, 
Storm Spirit
