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.
Troll Warlord
* 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.
Dragon Knight
* Timbersaw's pure damage will kill Dragon Knight surprisingly fast, especially if he gets caught in a bad position while laning.
Troll Warlord
* 
Timber Chain can kite Troll Warlord extremely effectively.
* 
Whirling Death and 
Chakram deals lots of damage to Troll Warlord.
* 
Reactive Armor makes Timbersaw extremely resilient to Troll's attack damage and extreme attack speed, especially during Battle Trance.
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.
Troll Warlord
* 
Atrophy Aura decreases Troll Warlord's damage.
* 
Pit of Malice helps lock down Troll Warlord.
* Battle Trance disallows Troll from running out of both 
Firestorm and Pit of Malice.
Dragon Knight
* 
Arcane Orb's constant pure damage output is devastating to Dragon Knight.
* Dragon Knight's relatively low mana pool leads to heavy damage from 
Sanity's Eclipse, which also bypasses his armor.
Troll Warlord
* Any heroes with low mana pools will die quickly or even instantly to Sanity's Eclipse: 
Doom, 
Phantom Assassin, 
Troll Warlord.
Additional:
* Outworld Destroyer's pure damage from Arcane Orb is very effective at killing Troll Warlord quickly.
* 
Astral Imprisonment removes Troll Warlord from a fight for four seconds, minimizing his contribution to a teamfight, and potentially wasting over half of Battle Trance's duration.
* Troll Warlord gains a measly 1 intelligence point per level, meaning Sanity's Eclipse is especially effective, often instantly killing him.
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.
Troll Warlord
* Melee heroes with low mobility can be kited and killed by Viper: 
Treant Protector, 
Kunkka, 
Alchemist, Troll Warlord, 
Wraith King, 
Tiny, 
Sven.
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
Troll Warlord
* 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
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.
Troll Warlord
* Heroes with high physical damage output but lack of reliable escape mechanisms are always a good target for a solo gank: 
Sniper, 
Shadow Fiend, Troll Warlord, 
Drow Ranger. Those heroes, however, are dangerous if they manage to close the gap, so take caution.
Troll Warlord
* 
Fate's Edict can disarm Troll, rendering him useless in a teamfight, especially if he has already used Battle Trance.
* 
Fortune's End and 
Purifying Flames can provide ample magic damage to help burst down Troll Warlord quickly in the early to mid game.
* 
False Promise can save an ally from Troll Warlord's initiation, forcing him to switch targets and lose his Fervor stacks, or waste time during Battle Trance.
Dragon Knight
* 
Fury swipes can tear Dragon knight down as it stacks infinitely.
Troll Warlord
* Troll Warlord's high attack speed means Counter Helix will proc extremely frequently even without creeps near him. This, combined with a 
Blade Mail means Axe can easily solo kill Troll Warlord even in later stages of the game.
* Battle Trance does not save Troll Warlord from a Culling Blade.
Additional:
* Troll Warlord has significant attack speed due to Fervor and Battle Trance, giving Axe a higher chance to proc 
Counter Helix and seriously injure Troll Warlord due to his relatively low maximum health.
* Axe often purchases Blade Mail, which can help Axe turn Troll Warlord's farm and high physical damage against him. The bonus armor provided by 
Berserker's Call means that Troll Warlord will take a lot more damage than Axe.
* 
Culling Blade is still capable of killing Troll Warlord during Battle Trance if his HP is low enough.
Troll Warlord
* 
Cold Embrace can protect Troll Warlord's target, especially during Battle Trance.
* 
Winter's Curse can turn Troll Warlord's high physical damage and attack speed against his allies.
Additional:
* Cold Embrace will protect your ally from being damaged if he gets focused by Troll, although be careful as 
Fervor will keep gaining stacks even while Cold Embrace is active.
* Fervor works on allies.
* His high attack speed will help to kill his cursed ally faster.
Troll Warlord
* Dark Willow's burst damage and stun prevents Troll Warlord from approaching her until he has Black King Bar.
* Troll Warlord's lack of burst damage makes it hard for him to kill Dark Willow before she slips into Shadow Realm.
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).
Troll Warlord
* Troll Warlord can't switch targets at will, in order to build Fervor stacks, which makes it easy to use Decrepify in order to save allies
* During Battle Trance, Pugna can easily use Nether Blast, Decrepify and Life Drain on him
Dragon Knight
* 
Viscous Nasal Goo slows down Dragon Knight and lowers armor, locking him down and making him more vulnerable.
Troll Warlord
* Troll Warlord is very susceptible to 
Pierce the Veil due to having low health and reliance on high armor.
* Troll Warlord's ultimate Battle Trance can simply be ignored by using Pierce the Veil.
* Troll Warlord's 
Rampage buff for allies can easily be countered by 
The Calling which will lower their attack speeds back to normal.
Troll Warlord
* Primal Roar and the slow from Boars make kiting Troll Warlord very easy.
Troll Warlord
* 
Clinkz, Sniper, 
Lone Druid, Troll Warlord, 
Legion Commander and Wraith King are some of the Heroes that base themselves on attacks with little or no spell power, so they suffer in the grassy hands of Overgrowth.
Dragon Knight
* 
Elder Titan's 
Natural Order completely nullifies Dragon Knight's high armor.
Dragon Knight
* Heroes with no mobility will take some good damage from Sand King's spells: Dragon Knight, 
Jakiro, 
Pugna, 
Earthshaker.
Troll Warlord
* 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.
Additional:
* 
Nightmare and 
Fiend's Grip help to control/disable Troll Warlord in team-fights.
Troll Warlord
* Troll Warlord's high speed attack makes Retaliate deal a lot of damage to him.
Troll Warlord
* Other heroes that rely on physical attacks to deal damage and not their abilities: Troll Warlord, Sniper, Monkey King, Sven.
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
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.
Troll Warlord
* 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.
Troll Warlord
* 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.
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.
Troll Warlord
* Heroes with mediocre health pools who rely on armor or evasion to survive fights such as Troll Warlord, Windranger, and Terrorblade can be killed by Zeus if caught off guard.
Troll Warlord
* Melee heroes who may struggle to get close to Sniper: Wraith King, Kunkka, Doom, 
Tidehunter, 
Underlord, Troll Warlord, and etc.
Additional:
* 
Shrapnel and 
Headshot allows Sniper to kite Troll Warlord effectively.
* 
Take Aim together with certain items such as 
Hurricane Pike allow Sniper to sit and fire at Troll Warlord from a safe distance.
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.
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.
Troll Warlord
* 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.
Troll Warlord
* Heroes who rely heavily on melee attacks and lack early spell immunity are easily blocked and interrupted by Ink Swell: Lycan, Ursa, Troll Warlord.
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
* 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
* 
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.
Troll Warlord
* 
Frostbite can disarm and root Troll Warlord if he doesn't have a Black King Bar or a 
Manta Style to dispel it.
* 
Crystal Nova and 
Freezing Field both significantly slow Troll Warlord, making him much more vulnerable to ganks or stuns.
* The magical damage from Freezing Field does a large amount of AoE damage, and Troll Warlord is not capable of cancelling Crystal Maiden's channel.
Troll Warlord
* Heroes with a low attack speed or are fragile will find themselves unable to deal with Troll Warlord's high physical damage and attack speed, like 
Crystal Maiden or Sven.
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.
Troll Warlord
* Heroes who build Black King Bar as either core or situational item will be able to fight back against Nyx Assassin and freely attack him as Spiked Carapace cannot pierce spell immunity at all: Axe, Broodmother, 
Dawnbreaker, 
Enigma, 
Huskar, Jakiro, Legion Commander, 
Lina, Luna, Lycan, Slardar, Slark, Troll Warlord, 
Witch Doctor.
Dragon Knight
* Heroes with high armor and/or durability can handle Juggernaut's ultimate, such as Sven and Dragon Knight.
Troll Warlord
* Troll Warlord's ability to attack as a ranged hero allows him to destroy Juggernaut's 
Healing Ward from afar.
* Battle Trance, when activated during 
Omnislash, allows Troll Warlord to survive the full duration of Omnislash and retaliate once it is over.
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
Troll Warlord
* 
Whirling Axes (Melee) makes it hard for Phantom Assassin to land a 
Coup De Grace.
* Troll Warlord often buys 
Silver Edge and 
Monkey King Bar, the items that greatly help against Phantom Assassin's Blur ability.
* Battle Trance completely negates Phantom Assassin's large damage output, preventing Troll Warlord from dying easily. The lifesteal also allows Troll Warlord to restore much of his health.
Additional:
* Troll Warlord can build a Silver Edge or a Monkey King Bar to completely ignore 
Blur.
* Whirling Axes (Melee) provides a 60% miss chance, making a Coup de Grace critical strike very hard to land.
* Battle Trance negates Coup de Grace, preventing Troll Warlord from dying to her critical hits.
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.
Troll Warlord
* 
Berserker's Rage will repeatedly trap Bloodseeker in a one-on-one fight.
* Whirling Axes (Melee) blinds Bloodseeker, causing him to miss 60% of the time, and therefore reduces his ability to gain the upper hand in teamfights.
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
Troll Warlord
* Whirling Axes (Melee)'s blind makes Sven nearly useless in the early game and allows Troll Warlord to take him on comfortably.
* Battle Trance will mean Sven will never take Troll out in a 1vs1 with equal farm.
Additional:
* Berserker's Rage together with Troll Warlord's high attack speed gives Troll a high chance of rooting enemies, which allows Troll Warlord to man-fight Sven.
* Whirling Axes (Melee) provides a 60% miss chance, and the passive armor provided by Berserker's Rage makes Troll resilient to physical damage in early game. Sven's 
God's Strength is much less effective as a result.
* Beware that Sven can farm much faster than Troll Warlord by stacking ancients and clearing them with 
Great Cleave.
Dragon Knight
* Heroes that are hard to gank: Dragon Knight, 
Mars, 
Centaur Warrunner.
Troll Warlord
* Whirling Axes (Melee) provides a 60% miss chance, which can make the attack speed bonus from Hunter in the Night largely ineffective.
* Berserker's Rage together with Battle Trance and Fervor stacks gives him a high chance of rooting Night Stalker, which allows Troll Warlord to man-fight Night Stalker in any stage of the game, regardless of whether or not it's night.
* Night Stalker is not a common Monkey King Bar carrier to counteract this problem.
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.
Troll Warlord
* Any hero who can survive Magnus's initiations and manfight him: Huskar, Faceless Void, Weaver, Abaddon, Troll Warlord, Alchemist, Dragon Knight, Night Stalker, Viper.
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.
Troll Warlord
* Terrorblade cannot go one on one against Troll Warlord as Troll Warlord will overwhelm him faster than the other way around thanks to Whirling Axes (Melee) that will cause his attacks to miss, and Fervor that can give Troll Warlord huge amounts of attack speed to outmatch Terrorblade, even during Metamorphosis.
* Troll Warlord's high attack speed from Fervor combined with 
Skull Basher and 
Abyssal Blade means that Terrorblade will have almost no chance to use 
Sunder to save himself.
* Even if Terroblade manages to use Sunder on Troll Warlord, Troll Warlord will simply be able to nullify it's effect with Battle Trance.
* Overall, any attempt for Terrorblade to engage and kill Troll Warlord will hurt him more than the other way around.
Additional:
* Terrorblade cannot go one on one against Troll Warlord as Troll Warlord will overwhelm him faster than the other way around thanks to Whirling Axes (Melee) that will cause his attacks to miss, and Fervor that can give Troll Warlord huge amounts of attack speed to outmatch Terrorblade, even during Metamorphosis.
* Troll Warlord's high attack speed from Fervor combined with Skull Basher and Abyssal Blade means that Terrorblade will have almost no chance to use Sunder to save himself.
* Even if Terroblade manages to use Sunder on Troll Warlord, Troll Warlord will simply be able to nullify it's effect with Battle Trance.
Troll Warlord
* Battle Trance and Fervor can help Troll Warlord deal with Enchantress through Untouchable.
Additional:
* 
Untouchable's attack speed slow is easily remedied by Fervor stacks and Battle Trance.
* Troll Warlord is a natural Silver Edge carrier, disabling Enchantress' Untouchable.
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.
Troll Warlord
* Generally speaking, Spectre is a strong teamfighter but a weak manfighter. She has no tool to deal with troll warlord once he has his sight locked on her.
* Troll often buys Silver Edge and Monkey King Bar, which greatly countered Spectre's passive and item build (Silver Edge can disable passive while providing some damage, Monkey King Bar provides accuracy to counter 
Radiance and 
Butterfly miss chance).
* Black King Bar allows troll to bypass the damage return from Blade mail should Spectre attempts to fight back Troll. However, Black King Bar is generally not very effective against Spectre as her skills can pierce the spell immunity. Still, it offers protection against Blade mail, a common item for Spectre in the mid game.
* Troll has high lifesteal from Battle Trance and 
Satanic, which help him survive the damage from 
Desolate should the break duration is over.
* Battle Trance and Fervor mean Spectre will have a hard time fighting troll and cannot take him down, even with equal farm.
Troll Warlord
* The ensnare from melee Berserker's Rage can prevent Primal Beast from dealing further Trample damage and can allow Troll Warlord to relentlessly build Fervor on him.
* 
Whirling Axes (Ranged) can slow down Primal Beast while trampling and allow Troll Warlord to better control him from range.
* Whirling Axes (Melee) can blind Primal Beast if he attempts to auto-attack Troll Warlord after a fully charged Uproar.
* Battle Trance will make Primal Beast a sitting duck should he be rooted and attacked to death.
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
* 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.
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
* 
Death Ward does little damage against Dragon Knight's armor, and Dragon Knight's high health regeneration minimizes damage from 
Maledict.
Troll Warlord
* Due to Fervor and Battle Trance, Troll Warlord has a significant attack speed, enabling him to crush 
Tombstone quickly.
* Undying usually stays at the front line with no disables, making him an easy target for Troll Warlord.
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.
Troll Warlord
* With Aghanim's Scepter upgraded 
Infest, Lifestealer can use it on enemy heroes to attack them and disarm them from inside, even if they are spell immune, which can give him the edge over the heroes he's weak against like Ursa, Phantom Assassin, Terrorblade or Troll Warlord.
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
Troll Warlord
* Lifestealer is a susceptible target to Fervor due to his non-mobile nature and lack of disables. Troll Warlord's ranged Berserker's Rage can also be used to kite Lifestealer safely. The root from its melee form also pierces magic immunity, which can potentially keep Lifestealer in place even while he is in Rage.
* Both Whirling Axes (melee) and Whirling Axes (ranged) can force Lifestealer to cast Rage too quickly and allow Troll Warlord to change strategies mid-fight, especially thanks to their separate cooldowns.
* Battle Trance allows Troll Warlord to survive Lifestealer's Feast and turn the fight in his favor.
Additional:
* The passive armor provided by Berserker's Rage makes Troll Warlord resilient to 
Feast in early game.
* The 60% miss chance given by Whirling Axes (Melee) is useful when 
Rage is not active.
* Battle Trance can purge 
Open Wounds, negating a large amount of Lifestealer's sustain in fights.
Troll Warlord
* Heroes that rely on right-clicks will find that their attacks will miss a lot, due to Whirling Axes (Melee)'s miss chance. Such heroes include Phantom Assassin, Terrorblade, and Morphling.
Dragon Knight
* Heroes with strong area-of-effect damage can make quick work of Chen's converted creeps and at same time gain farm: 
Magnus, Jakiro, Shadow Fiend, Kunkka, Luna, Dragon Knight, 
Medusa, Alchemist.
Dragon Knight
* Durable heroes can stand against Tusk during 1v1: Axe, Dragon Knight, Night Stalker, Centaur Warrunner, Wraith King and more.
Dragon Knight
* Heroes whose attacks can affect multiple enemies at once will clear Naga Siren's illusions. Such heroes include Sven, Magnus, Dragon Knight, Luna, Medusa, Templar Assassin, Gyrocopter, 
Muerta.
Dragon Knight
* Dragon Knight's insanely high armor and splash damage can cause Lycan to struggle taking him down.
Troll Warlord
* Mobility heroes will often be rooted by Troll Warlord and unable to escape, like 
Storm Spirit.
Troll Warlord
* 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.
Additional:
* Due to Fervor and Battle Trance, Troll Warlord is one of the best heroes to deal with Supernova.
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.
Troll Warlord
* Troll Warlord can root and deal a lot of damage to a single Meepo while lifestealing through the assault from the other Meepos. Meepo needs expensive items like 
Ethereal Blade or 
Heaven's Halberd to be able to fight him.
Dragon Knight
* Heroes that reduce the damage that Marci can deal during her ultimate, like 
Razor, 
Rubick, 
Bane, Dragon Knight and Underlord.
Troll Warlord
* Troll Warlord's melee bash and high attack speed can often help him and his allies win Duels against Legion Commander.
Troll Warlord
* Phantasm gives Chaos Knight a significant advantage against single-target damage dealers: Lifestealer, Wraith King, Night Stalker, Troll Warlord.
Additional:
* Chaos Knight's tanky illusions easily take advantage of Troll Warlord's lack of AoE damage.
* 
Chaos Bolt can stun Troll for up to 4 seconds and 
Reality Rift prevents Troll Warlord from chasing down foes.
* 
Phantasm increases Chaos Knight's physical damage output up to 4 times and can easily kill Troll Warlord before he has a chance to use Battle Trance or a Black King Bar.
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.
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
* 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.
Troll Warlord
* Carries that can out damage Huskar will do well against him: Legion Commander, Faceless Void, Troll Warlord, Phantom Assassin.
Additional:
* Whirling Axes (Melee) provides a 60% miss chance, resulting in Huskar's attacks missing a lot of the time if it isn't dispelled.
* Troll Warlord's Fervor ramps up in a very similar way as Huskar's 
Berserker's Blood: as soon as Huskar has high enough health regeneration, Troll Warlord has a high enough attack speed to negate it.
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.
Troll Warlord
* Troll Warlord's passive root, high attack speed, and blind from 
Whirling Axes makes him an exceedingly difficult opponent for Anti-Mage to take down in a one-on-one fight.
* Troll Warlord's low mana causes him to take little damage from Mana Void.
Additional:
* Whirling Axes (Melee) provides a 60% miss chance, preventing Anti-Mage from burning Troll Warlord's small mana pool.
* Troll Warlord's passive root allows him to very effectively fight an Anti-Mage by preventing Anti-Mage from 
Blinking away. This is even more effective when combined with a Skull Basher or Abyssal Blade.
* Counterspell will do nothing to prevent Troll Warlord's high physical damage.
* Due to Troll Warlord's abysmal base intelligence and intelligence gain, he is one of the worst targets to use 
Mana Void on.
Troll Warlord
* 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.
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.
Troll Warlord
* Shadow Shaman's long disables are effective at kiting and wasting the duration of Battle Trance.
* 
Mass Serpent Ward are especially effective against Troll Warlord during Battle Trance, as trapping him inside them during the duration is effectively another hard disable, as Troll cannot attack the wards or use Phase Boots to escape.
Dragon Knight
* Dragon Knight can simply tank and destroy all Shadow Shaman's Serpent Wards.
Dragon Knight
* Lich's constant slows with
Frost Blast and 
Chain Frost will slow Dragon Knight to a crawl, especially in a crowded teamfight.
Troll Warlord
*
Frost Blast and 
Chain Frost can kite Troll Warlord effectively.
Frost Shield can single-handedly waste most of the duration of Battle Trance, due to the extreme resistance to physical damage Frost Shield provides. In addition, Troll Warlord is incapable of switching targets during Battle Trance, so he cannot pick an easier target.
Frost Blast together with 
Frost Shield can harass him effectively.
*
* Troll Warlord has little to no ability to regenerate HP, so
