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.
Ember Spirit
* The pure damage provided by Arcane Orb is a great addition for killing Ember Spirit.
* Astral Imprisonment fully negates all magic damage of Flame Guard and Searing Chains and will temporarily save himself from Sleight of Fist's physical damage, and Ember Spirit is not a hero that can counter these skills.
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
Ember Spirit
* 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.
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.
Ember Spirit
* 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.
Troll Warlord
* Primal Roar and the slow from Boars make kiting Troll Warlord very easy.
Ember Spirit
* Heroes who rely on high mobility are especially vulnerable to Primal Roar: 
Storm Spirit, 
Ember Spirit, 
Queen of Pain.
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.
* Troll Warlord has little to no ability to regenerate HP, so Frost Blast together with Frost Shield can harass him effectively.
Ember Spirit
* Lone Druid becomes unkillable and impenetrable for Ember Spirit on the central line, as it has a huge reserve of health from the 
Summon Spirit Bear and a large regeneration from 
Spirit Link, which is why 
Sleight of Fist practically does not break through either one or the other on the line, and Lone Druid at this time can easily expel Ember Spirit from the line, push and gain gold and level
* 
Entangling Claws and 
Savage Roar abilities completely disable Ember Spirit's ability to dodge abilities or get out of an unpleasant fight for him on 
Fire Remnant, which can give the Lone Druid team the opportunity to kill him

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.
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
* 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.
Ember Spirit
* 
Global Silence and 
Last Word can prevent Ember Spirit from casting Activate Fire Remnant to escape.
* 
Glaives of Wisdom also provide high pure damage that is not negated by Flame Guard.
* 
Arcane Curse is also a potent harassing tool in the laneing stage as its cooldown is lower than Flame Guard's.
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
Ember Spirit
* Ember Spirit has a small mana pool, which is why QW-Invoker can burn it out very effectively with his own 
E.M.P., do not give Ember Spirit the opportunity to play with his abilities and cause damage with them in a fight.
* QW-Invoker Destroys Ember Spirit's Flame Guard with his own 
Tornado, which is why Ember Spirit cannot defend against Invoker's strong magic damage.

Ember Spirit
* Lion possesses two strong disables in 
Earth Spike and 
Hex and heavy magic burst with 
Finger of Death which help lock him down and prevent him from escaping with Activate Fire Remnant. When getting his 
Blink Dagger Lion can punish Ember Spirit's overextension immediately, or initiate a fight on him with disables.
Ember Spirit
* Using 
X Marks the spot Kunkka can prevent Ember Spirit from escaping with Activate Fire Remnant, until he purchase 
Eul's Scepter of Divinity or 
Linken's Sphere.
Ember Spirit
* Ember Spirit cannot use his 
Activate Fire Remnant to escape while affected by 
Doom.
Ember Spirit
* 
Shadowraze can easily remove the protection from Flame Guard and kill Ember Spirit due to his low health.
* Ember Spirit is very vulnerable to physical damage from 
Necromastery.
Ember Spirit
* Faceless Void is one of the best heroes against Ember Spirit, providing a lot of ways of dealing with him. Ember Spirit becomes a lot weaker if affected by 
Time Dilation, as he can no longer spam Sleight of Fist.
* 
Chronosphere is also a reliable lockdown for Ember Spirit, although it can be evaded sometimes by Activate Fire Remnant. Additionally, Void can easily negate Sleight of Fist damage with 
Time Walk.
* And finally, Void is a great 
Diffusal Blade carrier. Not only 
Manabreak's physical damage not negated by Flame Guard, but it also burns Ember Spirit's mana. That, in turn, prevents him from escaping if he survived Chronosphere.
Ember Spirit
* Batrider has huge damage from his 
Sticky Napalm and hand strikes on the target, with this effect. And Ember Spirit not only has a small reserve of health, but also has a melee type of attack. If these two collide on the center line, then Ember Spirit will have to finish off several creeps from afar with a Sleight of Fist, otherwise he will lose a lot of health from long-range Batrider attacks under Sticky Napalm, and possibly even kill, because Ember Spirit does not have the ability to interrupt Batraider with his damage if he decides to attack
* Ember Spirit is a very tasty target for 
Flaming Lasso, because it has a small reserve of health, and all the power lies in the abilities that Flaming Lasso forbids using, this can help the Batraider team quickly deal with the unpleasant "jumping" Ember Spirit in a fight if he gets into Flaming Lasso

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
* Troll Warlord's high speed attack makes Retaliate deal a lot of damage to him.
Troll Warlord
* Melee heroes with low mobility can be kited and killed by Viper: 
Treant Protector, 
Kunkka, 
Alchemist, Troll Warlord, 
Wraith King, 
Tiny, 
Sven.
Ember Spirit
* Any Hero with high mobility will be neutralized by dream coil: Queen of Pain, Storm Spirit, Ember Spirit, Lycan, 
Bloodseeker, 
Anti-Mage, 
Timbersaw.
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.
Ember Spirit
* Queen of Pain can be a good hero for dealing with Ember Spirit with Orchid Malevolence, her pure damage nuke in 
Sonic Wave and a slow in 
Shadow Strike. However, Queen of Pain can be punished by Ember Spirit, as his Searing Chains prevents her from getting 
Blink off.
Troll Warlord
* 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
* 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.
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.
Ember Spirit
* Huskar can destroy Ember Spirit both on the line and in the game. It will be extremely difficult for Ember Spirit to finish off the creeps, because Huskar will not let him approach them, and if Ember Spirit does come up, Huskar just shuts him up with his 
Burning Spear and Ember Spirit will have to go to the base or bring himself treatment, or continue to stand and die. In all cases, Ember Spirit will go into negative
Additional:
* Ember Spirit does minimal damage to Huskar until the very late game.
* Huskar can destroy Ember Spirit both on the line and in the game.

In all cases, Ember Spirit will go into negative
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.
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.
Ember Spirit
* Heroes with strong area-of-effect damaging and/or disabling abilities will be able to intercept Underlord and his team when they exit from Fiend's Gate: Luna's

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.
Ember Spirit
* Any hero with teleport abilities (e.g. Ember Spirit, Storm Spirit) can easily break Static Link.
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.
Ember Spirit
* Heroes with high physical and magical damage alike are a huge hazard for Muerta, as they can deal serious damage to her even if she has Pierce the Veil active: Luna, Lina, 
Tusk, Broodmother, Shadow Fiend, Ember Spirit, Gyrocopter, 
Vengeful Spirit, 
Arc Warden, Medusa, 
Shadow Shaman.
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.

* Even if Terroblade manages to use Sunder on Troll Warlord, Troll Warlord will simply be able to nullify it's effect with Battle Trance.
Ember Spirit
* Ember Spirit can deal devastating damage to illusion heroes like Terrorblade with Sleight of Fist. Terrorblade also has no way of preventing Ember Spirit from getting Activate Fire Remnant off. Additionally, Ember Spirit's ability to fight from long range as well as his wide skill set won't give many opportunities for Terrorblade to get Sunder off.
Additional:
* Ember Spirit can deal devastating damage to Terrorblade and his illusions with Sleight of Fist, Flame Guard and Fire Remnant.
* Terrorblade has no disable to lock down Ember Spirit and prevent him from escaping with Fire Remnant. In addition, he doesn't like purchasing disabling items like 
Scythe of Vyse or Abyssal Blade, which are the only solutions to deal with Ember Spirit.
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.
Ember Spirit
* Fire Remnant allows Ember Spirit to escape while Ruptured.
Additional:
* Fire Remnant allows Ember Spirit to escape Bloodseeker while 
Ruptured.
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.
Ember Spirit
* Heroes with escaping and disjointing abilities can be good against Juggernaut:Anti-Mage 
Riki, Queen of Pain, Puck, Storm Spirit, Ember Spirit, 
Slark etc.
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.
Ember Spirit
* Searing Chains and Flame Guard quickly burn through 
Refraction instances exposing her low health pool.
* Templar Assassin has no inherent way to prevent Ember Spirit from escaping, a good Ember player also will be able to dodge her meld attack
* Ember Spirit`s 
Searing chains give true sight into invisibility, why Templar Assassin can't hide from it in 
Meld and get out of the fight using Blink Dagger
Additional:
* Flame Guard burns quickly through Refraction charges, which is why it can interrupt Templar Assassin, giving his team the opportunity to kill her.
* Ember Spirit can dodge a blow from Meld with Sleight of fist, providing him an advantage in a 1v1 situation.
* Searing Chains give true sight into invisibility, why Templar Assassin can't hide from it in Meld and get out of the fight using Blink Dagger.
Ember Spirit
* Ember Spirit can easily deal with 
Nature's Call by using his Flame Guard and with 
Battle Fury. He also has multiple ways of escaping 
Sprout. Additionally, Ember Spirit can break Sprout's trees with Activate Fire Remnant and interrupt 
Teleportation with Searing Chains.
Additional:
* Sleight of Fist with Battle Fury deals a lot of damage to Nature's Prophet's team if they stand close to his Treants, as well as killing all the Treants with ease.
* Ember Spirit with Fire Remnant and 
Boots of Travel can be very active around the map, which enables him to quickly teleport and defend the objective Nature's Prophet is attacking whenever he tries to push.
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.
Ember Spirit
* Sleight of Fist is the natural counter to Phantom Lancer's army of illusions, especially when combined with Battle Fury.
Additional:
* Sleight of Fist, allows Ember Spirit to destroy all of Phantom Lancer's illusions.
* Flame Guard also deals significant damage to illusions, and protects against Spirit Lance.
* Phantom Rush is unable to catch Ember Spirit when he teleports to his Fire Remnants.
Ember Spirit
* Flame Guard makes Dark Seer not deal any damage with his skills to Ember Spirit.
Ember Spirit
* Searing Chains can stop Charge of Darkness if timed correctly.
* Activate Fire Remnant can be used to escape an approaching Spirit Breaker, or lead Spirit Breaker into a bad situation.
* Fire Remnant and Sleight of Fist allows Ember Spirit to dodge Charge of Darkness if timed correctly.
Ember Spirit
* Ember's magic damage build is able to burst down Alchemist due to his low strength gain and Alchemist's normal item pick up.
Ember Spirit
* A pre-placed Fire Remnant allows Ember Spirit to escape Upheaval.
* Flame Guard blocks Shadow Word's damage.
* Sleight of Fist allows Ember Spirit to attack from outside of Upheaval's range, and Searing Chains lets him interrupt it.
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.
Ember Spirit
* Ember Spirit easily finishes off all creeps on the line against Earth Sprit, exchanging health with him under his Flame Guard, which is why Earth Spirit can leave the line for ganks very early and without the necessary amount of gold and levels, which will give the Ember Spirit team an advantage to fight off such ganks
* The Sleight of Fist ability helps Ember Spirit dodge all of Earth Spirit's abilities, which makes his gank potential practically useless against Ember Spirit, and with the purchase of 
Black King Bar, Ember Spirit can use Sleight of Fist to combine with Searing Chains to catch and kill Earth Spirit.
Additional:

* The Sleight of Fist ability helps Ember Spirit dodge all of Earth Spirit's abilities, which makes his gank potential practically useless against Ember Spirit, and with the purchase of Black King Bar, Ember Spirit can use Sleight of Fist to combine with Searing Chains to catch and kill Earth Spirit.
Ember Spirit
* Ember Spirit has much higher mobility in Fire Remnant than Void Spirit.
* Ember's Flame Guard is effective against Void Spirit's spells, as most of them deal magical damage.
* The root from Searing Chains prevents Void Spirit from using Dissimilate or Astral Step.
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
* 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.
Ember Spirit
* Heroes with high mobility can be prevented from using it to their advantage with Earthbind, even if they pack a dangerous arsenal: 
Earth Spirit, Ember Spirit, Storm Spirit, 
Nature's Prophet, Phantom Assassin, Riki, Anti-Mage, Weaver.
* See items and abilities disabled by roots
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.
Ember Spirit
* Meepo is quite fragile in the early game and can be easily taken down by Flame Guard's and Searing Chains' damage. Later on, Meepo is very vulnerable to Sleight of Fist's damage due to Battle Fury's cleave on multiple Meepos.
Additional:
* Sleight of Fist combined with Battle Fury, 
Maelstrom and 
Daedalus will allow Ember Spirit to make a quick work of Meepo if his clones are crowded around each other.
* Searing Chains interrupts Meepo's initiating because Meepo's clones do not have spell immunity.
Ember Spirit
* Ember Spirit absorbs quite a large amount of magical damage with its Flame Guard, and in addition dodges the abilities of 
Dragon Slave and Light Strike Array with its Sleight of Fist
Additional:
* Ember Spirit absorbs quite a large amount of magical damage with its Flame Guard, and in addition dodges the abilities of Dragon Slave and Light Strike Array with its Sleight of Fist.
Ember Spirit
* Sleight of Fist keeps Ember Spirit invulnerable until he hits every unit in its area of effect allowing him to stall for large amounts of time against Broodmother and her large amounts of spiderlings, or potentially damaging them enough if equipped with an item to improve wave clearing such as Battle Fury or Maelstrom to prevent her pushes entirely.
* Flame Guard will damage any of Broodmother's spiders in an area, deterring her from attempting to kill him. It can also be used during Sleight of Fist to amplify damage done.
* Fire Remnant allows Ember Spirit an escape from Broodmother that is unaffected by her Incapacitating Bite.
Ember Spirit
* Ember Spirit's Fire Remnant is an easy way to escape from Clockwerk's Power Cogs.
* Flame Guard blocks most of the magical damage Clockwerk does.
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.
Ember Spirit
* Certain Hero's potential lies on the combo of their abilities. As an example, Ember Spirit can cast Sleight of Fist and Searing Chains together to root and damage enemies from a far distance. Yet for 
Rubick, casting Searing Chains can only catch enemies at a close distance, and Sleight of Fist does little more than a scratch of right click.
* It is arguably possible to group spells together after getting Aghanim's Scepter, but stealing two separate spells from one single enemy is somewhat luxurious in an intense fight.
Ember Spirit
* Heroes with considerable mobility can easily escape from a rolling Pangolier: Anti-Mage, Queen of Pain, 
Void Spirit, Storm Spirit, Ember Spirit, Earth Spirit, moreover, if a player is familiar with how Rolling Thunder works, they can adjust their movement to avoid it entirely and of course outplay the Pangolier player.
Ember Spirit
* Heroes that heavily depend on illusions or summons, (Naga Siren, 
Terrorblade, 
Phantom Lancer, Lycan,...) are vulnerable to Sleight of Fist and even more so if Ember Spirit has Battle Fury.
Ember Spirit
* Heroes with high mobility will be able to avoid Gyrocopter's area attacks: Storm Spirit, 
Morphling, Ember Spirit
Ember Spirit
* Heroes that can easily bypass Chen's creeps to get to Chen: Riki, Tusk, Clinkz, Sniper, Slark, Phantom Assassin, Void Spirit, Storm Spirit, Ember Spirit, Earth Spirit, 
Spirit Breaker.
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.
Ember Spirit
* Crystal Maiden is extremely fragile and she's an easy target for him. She has no real disables that can lock Ember Spirit down, and all of her skill damage can be negated with Flame Guard. The damage from Searing Chains, Flame Guard, and Sleigh of Fist can easily take her down.
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.
Ember Spirit
* Heroes with a high degree of mobility and invisibility are hard to catch with Meat Hook: Ember Spirit, Riki, Clinkz, Queen of Pain.
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.
Ember Spirit
* Storm Spirit is not only a potent Orchid Malevolence carrier, his 
Electric Vortex provides an additional disable and 
Overload provides a great slow. When paired with 
Static Remnant, they can cut through Flame Guard fast.
* 
Ball Lightning not only provides great initiation upon Ember Spirit from any position anytime, but also helps dodge Sleight of Fist.
Troll Warlord
* Mobility heroes will often be rooted by Troll Warlord and unable to escape, like Storm Spirit.
Ember Spirit
* Flame Guard absorbs up to 500 magical damage (700 with Level 10 talents), which helps Ember Spirit survive against Storm Spirit's high magical damage.
* Searing Chains can root enemies up to 3 seconds, making Storm Spirit unable to escape with Ball Lightning.
* Fire Remnant deals high magical damage when casting multiple instances at once, granting Ember Spirit the damage to burst Storm Spirit down in the early to mid game.
Ember Spirit
* Heroes that can reliably kite out Dispose, Unleash and dodge Rebound, like Ember Spirit, Void Spirit, Storm Spirit, Anti-Mage, Faceless Void, Puck or always build items like Blink Dagger and 
Force Staff.
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.
Ember Spirit
* Ember Spirit with Sleight of Fist and Activate Fire Remnant
* Heroes that can dodge Glimpse:
* Puck with 
Phase Shift
* Riki with 
Tricks of the Trade
* Phantom Lancer with 
Doppelganger
* Ember Spirit with Sleight of Fist and Activate Fire Remnant
* 
Chaos Knight with 
Phantasm
* Naga Siren with 
Mirror Image
* Tusk with 
Snowball
* Juggernaut with Omnislash
* 
Brewmaster with 
Primal Split
* Lifestealer with 
Infest
* 
Phoenix with Supernova
Ember Spirit
* Heroes that heavily depend on illusions or summons, (Naga Siren, Terrorblade, Phantom Lancer, Lycan,...) are vulnerable to Sleight of Fist and even more so if Ember Spirit has Battle Fury.
Troll Warlord
* Troll Warlord's melee bash and high attack speed can often help him and his allies win Duels against Legion Commander.
Ember Spirit
* Heroes with either magical, physical or pure damage burst: 
Bane, Ember Spirit, 
Leshrac, Lina, Luna, 
Nyx Assassin, Phantom Assassin, 
Skywrath Mage, 
Tinker, Ursa, Void Spirit.
Troll Warlord
* Other heroes that rely on physical attacks to deal damage and not their abilities: Troll Warlord, Sniper, Monkey King, Sven.
Ember Spirit
* The high mobility provided by Fire Remnant makes it hard for Windranger to find a good position to land Shackleshot or a full duration of Focus Fire.
* Flame Guard and Searing Chains deal considerable magical damage to Windranger which she cannot avoid with Windrun.
* Searing chains also negates the mobility from Windrun.
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.
Ember Spirit
* Ember Spirit can close the distance between Sniper easily with his Activate Fire Remnant and further keep Sniper in place with Searing Chains.
* With the help of Aghanim's Scepter, Sniper cannot outrun Ember Spirit or chase him, even if Sniper builds mobility items.
Ember Spirit
* Anti-mage is potentially good against Ember Spirit since he can burn Ember Spirit's mana, prevent him from escaping or using his skill. Anti-Mage has high magic resistance, which will reduce most of the damage from Ember Spirit's skill set. However, Anti-Mage lacks any form of stuns or lockdowns, and may struggle to kill Ember Spirit if he still has some mana left.
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
* 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.
Ember Spirit
* Disruption is not reliable enough to catch an Ember Spirit with a backup Fire Remnant.
* Sleight of Fist will also make quick work of the spawned illusions.
* The best you can do against an Ember Spirit is to dispel his Flame Guard with your Demonic Purge.
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.
Ember Spirit
* Zeus laneing against Ember is going to be punished with Sleight of Fist due to his low health pool
* Zeus's chip damage from 
Arc Lightning and other spells is nullified from Ember's Flame Guard.
Additional:
* Ember Spirit has a built-in antimagic shield, and Zeus has nothing but this magical damage, because of this, their confrontation on the center line can turn out to be sad for Zeus. If on such a line Ember Spirit will finish off all creeps under its Flame Guard, and Zeus with the help of Arc Lightning, then eventually Zeus will lose mana faster, and will be forced to look for ways to replenish it
* Ember Spirit can interrupt Zeus with his "jumping" abilities, the fact is that Zeus deals damage from his abilities directly, while Ember Spirit disappears for milliseconds from the battlefield when flying during the Sleight of Fist action or when flying into Fire Remnant
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.
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.
Ember Spirit
* With 
Vendetta, Nyx Assassin can move closely to Ember Spirit when he's farming with his Flame Guard and use 
Spiked Carapace with 
Impale to provide a reliable and long disable.
Additional:
* Spiked Carapace can be easily triggered by Flame Guard or Battle Fury, setting up a deadly Impale.
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.
Ember Spirit
* Heroes who rely on damage over time as Spiked Carapace can block and reflect only one instance of damage: Jakiro, Viper, Venomancer, Huskar, Ember Spirit, Dark Seer, Sand King, Doom, Dawnbreaker. However, this also means they are easily stunned.
Ember Spirit
* Impetus will deal huge amounts of damage when he uses a Fire Remnant to escape.
* Flame Guard is useless against Impetus as it deals Pure damage.
* Enchant can be used to dispel Flame Guard.
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.
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.
Ember Spirit
* Searing Chains prevents usage of Timber Chain.
* Timbersaw is vulnerable to magical burst damage, which Ember Spirit provides with Fire Remnant and Flame Guard.
* Timbersaw's abilities deal pure damage, thus they cannot remove Flame Guard.
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.
Ember Spirit
* Heroes with good mobility to avoid Jakiro's abilities and with good chase to punish Jakiro from pushing a tower: Bloodseeker, Ember Spirit, Juggernaut, Phantom Assassin, Weaver.
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.
Ember Spirit
* Heroes with strong area damage to destroy Phantasm illusions: Axe, Ember Spirit, Legion Commander, Phoenix
Additional:
* Ember Spirit is evasive and can dodge close encounters with melee heroes like Chaos Knight. Ember Spirit can't be caught with the slow from Reality Rift, and Flame Guard and Sleight of Fist can bring Phantasm's illusions down quickly.
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.
Ember Spirit
* Flame Guard blocks Dark Willow's magical burst damage, and harms her if she tries to get close to attack with Bedlam.
* Sleight of Fist and Fire Remnant makes it hard for Dark Willow to fully disable Ember Spirit.
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.
Ember Spirit
* Heroes who commonly buy Linken's Sphere: Luna, Weaver, Morphling, Queen of Pain, Ember Spirit.
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.
*
*
Ember Spirit
* Oracle can shut down both of Ember's early game abilities. Fortune's End can dispel
Flame Guard on Ember Spirit and 
Searing Chains on allies.
Fire Remnants move at 0 movement speed.
Sleight of Fist ability, possibly making him useless for a few seconds in the late game without a dispel or spell immunity. This is especially good if he has a rapier or two. However, positioning for this is difficult when Ember plays far back.
* When Ember Spirit is affected by Fortune's End, his
* Disarming him with Fate's Edict does affect Ember's
