Dragon Knight
* Counterspell can helpful blocked off to 
Dragon Tail.
Additional:
* 
Counterspell makes Anti-Mage exceptionally resistant to Breathe Fire, Dragon Tail, Fireball (requires 
Aghanim's Shard) and Elder Dragon Form's attacks. Its active component also blocks and reflects Dragon Tail back at Dragon Knight.
* 
Mana Break drains Dragon Knight's small mana pool, although it won't affect Dragon Knight much if he is in his Elder Dragon Form.
Brewmaster
* Blinking heroes like 
Anti-Mage or 
Queen of Pain can often chase down an injured Brewmaster after his ultimate expires.
Dragon Knight
* Because Exorcism's damage is not reduce by damage block abilities or items, Death Prophet can be very good against heroes who rely on armor to survive: 
Axe, 
Terrorblade, 
Morphling, 
Dragon Knight
Brewmaster
* 
Exorcism kills Primal Split's units very quickly.
Brewmaster
* After Brewmaster has committed Thunder Clap and Cinder Brew to gank, Bane can use 
Nightmare on Brewmaster to wait out the debuffs, and might even turn the tables by buying time for allied reinforcements.
* Bane can also prevent Brewmaster from using Primal Split with his long disables.
Dragon Knight
* Dragon Knight has no built-in disengage from 
Frost Arrows, and 
Marksmanship procs ignore base armor, bypassing Dragon Knight’s durability for the most part, making Drow one of the few heroes that can deal enough sustained damage to solo kill Dragon Knight.
* With 
Aghanim's Scepter, Frost Arrows also apply hypothermia stacks, reducing her target’s regen, which is especially potent against tanks like Dragon Knight. (A similar effect can also be achieved with an 
Eye of Skadi).
Brewmaster
* Brewmaster is slow and has low armor, making his laning stage very difficult against Geminate Attack.
* Apart from the slow moving 
Hurl Boulder, which can be disjointed, he has no control to catch Weaver.
Dragon Knight
* Lich's constant slows with 
Frost Blast and 
Chain Frost will slow Dragon Knight to a crawl, especially in a crowded teamfight.
Brewmaster
* 
Hex's instant cast time will force Brewmaster into the awkward situation of needing some form of spell immunity or block to prevent being immediately hex upon blinking in, or wait until Lion has used all his crowd control before entering a fight. His direct magic burst also makes Brewmaster's Drunken Brawler worthless versus Lion.
Dragon Knight
* 
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.
Dragon Knight
* In the early game, a Dragon Knight without Black King Bar is basically defenseless against Viper.
* Viper can harass Dragon Knight at any time with his 
Poison Attack and 
Nethertoxin.
* 
Corrosive Skin reduces damage from Dragon Fire and inflicts damage to him.
* 
Viper Strike disables Dragon Blood, negating his main survivability.
* Viper Strike and Poison Attack can severely slow him down even with his Elder Dragon Form.
Additional:
* Dragon Knight is easily harassed by Poison Attack after the laning stage ends.
* Corrosive Skin protects Viper from 
Breathe Fire and returns damage.
* Viper Strike can disable 
Dragon Blood, Dragon's Knight main source of armor and health regeneration.
* Between Poison Attack and Viper Strike, Viper can keep Dragon Knight permanently slowed even in 
Elder Dragon Form.
Brewmaster
* 
Ancient Seal's instant cast time will often silence Brewmaster before he can do anything.
* Brewmaster also has no defense against Skywrath Mage's massive magical damage.
Dragon Knight
* 
Viscous Nasal Goo slows down Dragon Knight and lowers armor, locking him down and making him more vulnerable.
Dragon Knight
* Timbersaw's pure damage will kill Dragon Knight surprisingly fast, especially if he gets caught in a bad position while laning.
Dragon Knight
* 
Slardar can chase Dragon Knight down with 
Guardian Sprint and stun him with both 
Slithereen Crush and his passive 
Bash of the Deep. He can also use 
Corrosive Haze to whittle Dragon Knight's armor.
Dragon Knight
* Heroes with long cooldowns on their abilities or ultimate will struggle against the relentless pressure provided by 
Fiend's Gate: Terrorblade, Dragon Knight, 
Omniknight.
Dragon Knight
* Heroes that relies on armor or other type of physical damage negation are easy for Gyrocopter to take down during the early game with his magical damage: Axe, Dragon Knight, 
Sven.
Brewmaster
* Blinking heroes like Anti-Mage or Queen of Pain can often chase down an injured Brewmaster after his ultimate expires.
Brewmaster
* Heroes with strong team-fight abilities (especially ultimates) like 
Tidehunter, 
Brewmaster, 
Death Prophet, etc.
Dragon Knight
* In general, heroes that can slow down Dragon Knight's movement speed will do well against him. This includes 
Venomancer and others in addition to the heroes mentioned above.
Dragon Knight
* Heroes that lose a great amount of their tankiness and become easier to finish off: 
Bristleback, 
Spectre, 
Phantom Assassin, 
Enchantress, Dragon Knight.
* Once you have an Aghanim's Scepter, Shadow Demon instantly reaches a new power spike and becomes a counter for a variety of heroes that have strong passives.
* Heroes that lose a great amount of their tankiness and become easier to finish off: Bristleback, Spectre, Phantom Assassin, Enchantress, Dragon Knight.
* Heroes that lose a great amount of damage output and become less threatening: Phantom Assassin, Sven, 
Slark, 
Phantom Lancer.
* You can always stack camps and farm the scepter with Shadow Poison.
Dragon Knight
* Heroes who rely on burst physical damage are affected by Lucky Shot's disarm: Terrorblade, Sven, 
Clinkz, 
Windranger, 
Alchemist, Dragon Knight, 
Legion Commander
Dragon Knight
* Durable heroes relied a lot on their main passive effects and items' effects such as Bristleback, 
Underlord, Spectre and Dragon Knight can be disabled easily with 
Sharpshooter's break, reducing their potential in teamfights.
Dragon Knight
* Heroes with no mobility will take some good damage from Sand King's spells: Dragon Knight, 
Jakiro, 
Pugna, 
Earthshaker.
Dragon Knight
* 
Heartstopper Aura and 
Reaper's Scythe go right through Dragon Knight's armor.
Dragon Knight
* Enemies that possess high defenses through magic resistance, damage reduction, or high regeneration will make it difficult to whittle their health down to get to Reaper's Scythe's threshold. Such heroes include Bristleback (although only from behind), Spectre, 
Ursa, and Dragon Knight.
Dragon Knight
* Despite the armor reduction from 
Meld, Templar Assassin's reliance on physical damage and medium attack speed is unlikely to harm Dragon Knight.
* Templar Assassin's Refraction charges also get quickly removed by the damage over time from Dragon Knight's ultimate.
Additional:
* The damage over time from Dragon Knight's Elder Dragon Form rapidly burns down Refraction, allowing him to attack her.
* Also, Breathe Fire reduces Templar Assassin's damage and Dragon Tail is a stun with a considerable duration, letting him and his team whittle her health down once her defenses wear off.
* Templar Assassin will struggle to kill Dragon Knight thanks to his high armor and health regen from Dragon Blood as she deals entirely physical damage.
Brewmaster
* The three Primal Split brewlings all attacking Templar Assassin at once will remove her 
Refraction quickly, especially with Fire's Permanent Immolation.
* Templar Assassin has no way to stop Brewmaster from using Primal Split by herself, and may get unlucky and miss her Meld if trying to burst him during her ally's disable.
Dragon Knight
* Dragon Blood's armor bonus greatly reduces the damage dealt by Phantasm.
* Breathe Fire and Elder Dragon Form's splash damage quickly destroy illusions and reduces their damage output.
Brewmaster
* Storm's Dispel Magic combined with Thunder Clap deals high damage against Chaos Knight's illusions even in the late game.
* Chaos Knight's reliance on physical damage is easily hindered by Drunken Brawler.
* Chaos Knight's lack of area effect and mobility makes him easily overwhelmed by Primal Split.
Additional:
* 
Dispel Magic from {U:Storm} can instantly kill Phantasms early on, and can still deal a lot of damage to them late game, revealing the real Chaos Knight.
Dragon Knight
* Dragon Knight's heavy armor negates 
Vendetta's burst physical damage. His large HP pool also gives him a good chance of surviving Nyx Assassin's follow-up nuke damage.
Brewmaster
* 
Cyclone from Storm in 
Primal Split can waste Nyx's Spiked Carapace, since its duration is shorter than the Cyclone's.
Dragon Knight
* Dragon Knight's insanely high armor and splash damage can cause Lycan to struggle taking him down.
Brewmaster
* Brewmaster can waste a large portion of Lycan's ultimate by putting him in Cyclone.
* Lycan has no way to stop Brewmaster from using Primal Split by himself.
* Lycan's team often tries to push towers as a group, and Brewmaster excels at winning teamfights while trying to defend a tower.
Dragon Knight
* Breathe Fire will clear Broodmother's spiderites while significantly damaging her spiderlings and decreasing their damage output.
* Dragon Blood's added armor and regen mitigates the damage done by Broodmother and her spiders.
* Elder Dragon Form at level 2 and above applies splash damage to Dragon Knight's auto attacks.
Brewmaster
* Heroes who produce many summons will have a hard time against Storm's Dispel Magic during teamfight: 
Broodmother, 
Enigma, 
Nature's Prophet.
Dragon Knight
* Heroes that rely on physical damage are ineffective against Dragon Knight due to his high armor: Phantom Assassin,
Bloodseeker, 
Lifestealer, 
Troll Warlord, Sven
Brewmaster
* 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.
Dragon Knight

Brewmaster
* 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.
Dragon Knight
* 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.
Brewmaster
* 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.
Dragon Knight
* The dragon's splash damage wears down his illusions.
* Early harassment with Breath of Fire hinders his farming.
* Fireball stops his pushes and allows for a defence.
Additional:
* Breathe Fire and Elder Dragon Form's splash damage takes out Phantom Lancer's illusions quickly.
* If Dragon Knight can Dragon Tail the real Phantom Lancer, he and his team can quickly kill him before he has a chance to escape.
Brewmaster
* 
Cinder Brew and 
Drunken Brawler makes it hard for Monkey King to stack Jingu Mastery.
* Cyclone can remove Monkey king for 6 seconds if his allies lack dispels.
* Dispel Magic can dispel Jingu Mastery's bonuses.
Dragon Knight
* Spirit Breaker's slow attack speed and moderate damage do very little to harm Dragon Knight, even if ganked with 
Charge of Darkness.
Dragon Knight
* Riki does little damage to Dragon Knight, as he relies only on physical damage with modest attack speed and lack of burst.
Dragon Knight
* 
Death Ward does little damage against Dragon Knight's armor, and Dragon Knight's high health regeneration minimizes damage from 
Maledict.
Dragon Knight
* If Silencer can't prevent Dragon Knight from using Elder Dragon Form, Silencer's spells aren't going to be that effective against him, as Dragon Knight relies on right-clicks and not spells.
* Dragon Blood's armor bonus and health regeneration allows Dragon Knight to stay in the lane against Glaives of Wisdom.
* Dragon Knight often builds Black King Bar, allowing him to remove Global Silence before engaging.
Brewmaster
* Brewmaster can make the Spirit Bear a much smaller threat with Cinder Brew.
* Cyclone removes the bear from a fight so that his team can easily focus on the hero.
* While most heroes would be worn down by a Spirit Bear 
Radiance in the time it takes to kill Lone Druid, Brewmaster is protected in Primal Split.
Brewmaster
* {U:Storm} can use Cyclone on Abaddon when he activates Borrowed Time, wasting its duration.
* Drunken Brawler and 
Thunder Clap hinder Abaddon from applying Curse of Avernus' silence on him.
Additional:
* Dispel Magic can remove Abaddon's 
Aphotic Shield or 
Curse of Avernus on an allied hero.
* Cyclone's lengthy duration wastes much of 
Borrowed Time's duration.
Dragon Knight

Magnus, Dragon Knight, 
Luna, 
Medusa, Templar Assassin, 
Gyrocopter,

Dragon Knight
* Durable heroes can stand against Tusk during 1v1: Axe, Dragon Knight, 
Night Stalker, 
Centaur Warrunner, 
Wraith King and more.
Dragon Knight
* Heroes that rely on physical damage are ineffective against Dragon Knight due to his high armor: Phantom Assassin,Bloodseeker, Lifestealer, Troll Warlord, Sven
Dragon Knight
* Heroes who can match Void Spirit's mobility (like the aforementioned 
Ember Spirit or Queen of Pain) or tank his spells (Dragon Knight or Centaur Warrunner) are very problematic for him.
Brewmaster
* Heroes who produce many summons will have a hard time against Storm's Dispel Magic during teamfight: Broodmother, Enigma, Nature's Prophet.
Dragon Knight
* Heroes with high armor and durability can be exceptionally hard for Bloodseeker to bring down: Dragon Knight, Axe
Additional:
* Bloodseeker's physical damage is unlikely to kill Dragon Knight, and therefore rarely get a chance to recover the large amount of HP from 
Bloodrage.
Dragon Knight
* Any hero who can survive Magnus's initiations and manfight him: 
Huskar, Faceless Void, 
Weaver, 
Abaddon, Troll Warlord, Alchemist, Dragon Knight, Night Stalker, 
Viper.
Brewmaster
* 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.

* Heroes that rely on physical damage are ineffective against Dragon Knight due to his high armor: Phantom Assassin,Bloodseeker, Lifestealer, Troll Warlord, Sven
Dragon Knight
* Shadow Fiend's 
Presence of the Dark Lord reduces Dragon Knight's armor considerably, and his strong base attacks are augmented by his 
Necromastery.
Dragon Knight
* Dragon Tail can be used to cancel Requiem of Souls.
* Breathe Fire reduces Shadow Fiend's damage even further.
* Dragon Knight's high strength and Dragon Blood means that he'll be able to tank Shadow Fiend's right clicks.
Dragon Knight
* 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
Brewmaster
* Dispel Magic from {U:Storm} instantly removes Heavenly Grace and Guardian Angel from Omniknight's allies in its radius of effect.
Dragon Knight
* Huskar can burn down Dragon Knight's health quickly during the early to mid game, but is not as effective during the late game. However, 
Life Break remains a constant threat due to the slow and percentage-based damage.
Additional:
* Huskar can negate Dragon Knight's passive with multiple trades of Burning Spear.
Brewmaster
* Brewmaster can use Cyclone to disable Huskar's healer for much longer than most other heroes can, to make Huskar vulnerable.
* Huskar has no way to stop Brewmaster from using Primal Split by himself, but can cut a good amount of his high health away if Huskar's team wants to burst Brewmaster down during a different disable.
Dragon Knight
* Heroes that withstand damage like 
Timbersaw, Bristleback, Dragon Knight and others will have their durability largely reduced when hit by an Ice Blast due to the risk of shattering.
Additional:
* 
Cold Feet and 
Ice Vortex both hinder Dragon Knight's movement greatly during teamfights.
* 
Ice Blast ignores Dragon Knight's armor, disables his health regeneration, and kills him prematurely.
Brewmaster
* Primal Split makes Brewmaster invulnerable for the duration, rendering effects of Cold Feet and Ice Blast useless.
* Dispel Magic can dispel Cold Feet from allies.
* Brewmaster can easily run Ancient Apparition down with the slow from Thunder Clap and Cinder Brew.
Dragon Knight
* 
Elder Titan's 
Natural Order completely nullifies Dragon Knight's high armor.
Brewmaster
* {U:Earth} has passive 
Spell Immunity, allowing him to walk into the Echo Stomp radius to stun Elder Titan with his Hurl Boulder.
* {U:Storm}'s Cyclone can cancel the channeling of Echo Stomp and take Elder Titan out of the fight for {show:A|Storm|Cyclone|value2} seconds.
Dragon Knight
* 
Fury swipes can tear Dragon knight down as it stacks infinitely.
Brewmaster
* If Ursa uses 
Enrage Brewmaster can use Cyclone to render him harmless during his ultimate.
* Brewmaster has two spells to slow down Ursa, allowing his team to kite around him easily.
Brewmaster
* 
Hex's instant cast time will force Brewmaster into the awkward situation of needing some form of spell immunity or block to prevent being immediately hex upon blinking in, or wait until Shaman has used all his crowd control before entering a fight.
* Brewmaster also has no defense against Shadow Shaman lockdowns.
Dragon Knight
* Dragon Knight can simply tank and destroy all Shadow Shaman's Serpent Wards.
Dragon Knight
*
Arcane Orb's constant pure damage output is devastating to Dragon Knight. 
Sanity's Eclipse, which also bypasses his armor.
