Undying
* 
Reactive Armor makes Timbersaw very effective against heroes that control a lot of units, such as 
Broodmother, 
Lycan and 
Undying.
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.
Undying
* Sniper can easily destroy 
Tombstone from long range.
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.
Undying
* 
Chaos Knight's multiple illusions from 
Phantasm can destroy Undying, as Soul Rip can't offset the damage from the high amount of damage from his illusions.
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.
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.
Undying
* Split Shot can destroy Tombstone Zombies and Tombstone itself while still damaging heroes.
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
* 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
* 
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.
Undying
* Zombies summoned from Tombstone will amplify the damage of 
Echo Slam due to them increasing the echo damage.
Undying
* Chemical Rage will take down Tombstone in no time.
Additional:
* With 
Greevil's Greed, Alchemist can farm Tombstone zombies and gain a significant gold advantage.
Undying
* Geminate Attack works on Tombstone, allowing Weaver to kill it quickly.
* Zombies attacking Weaver disappear once he goes invisible with Shukuchi.
* Undying has no way to catch a mobile Weaver.
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.
Undying
* Tidehunter takes close to no damage from Undying's zombies once he maxes out his 
Kraken Shell, especially if he gets the level 20 Kraken Shell upgrading talent. This might allow him to blink away to safety.
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.
Undying
* 
Arcane Curse can effectively discourage Undying from casting his spammable abilities in a team fight, as Undying will have to suffer more damage and the slow due to the penalty duration of Arcane Curse.
* 
Last Word and 
Global Silence are able to silence Undying for up to 6 seconds, preventing Undying from gaining strength and healing his ally or himself.
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
Undying
* Luna's 
Moon Glaives and 
Lunar Blessing can help her destroy Tombstone easily, and this becomes more effective if Luna is equipped with 
Manta Style.
* Spell Immunity of Zombies from Tombstone is a total disadvantage against Luna because 
Eclipse will strike only Undying, which can turn Undying's own ability against him.
* Though Undying often builds Blade Mail which can turn Luna's burst damage against her, Luna often builds Black King Bar which will allow her to attack Undying freely because Blade Mail cannot pierce spell immunity.
Additional:
* Luna's Moon Glaives and Lunar Blessing can help her destroy Tombstone easily, and this becomes more effective if Luna is equipped with Manta Style.
* Spell Immunity of Zombies from Tombstone is a total disadvantage against Luna because Eclipse will strike only Undying, which can turn Undying's own ability against him.
* Though Undying often builds Blade Mail which can turn Luna's burst damage against her, Luna often builds Black King Bar which will allow her to attack Undying freely because Blade Mail cannot pierce spell immunity.
Undying
* Necrophos is a dangerous opponent to go against with. Regardless of how much strength Undying has gained from Decay, Necrophos can finish off Undying with 
Reaper's Scythe once Undying's HP falls below a certain threshold.
* 
Heartstopper Aura will do more damage to Undying if he gained strength from Decay, as it does damage based on a hero's maximum health.
Undying
* Tombstone can be stolen to counter-initiate the enemy team in skirmishes.
* Tombstone provides vision over the enemy around, use this to Rubick's advantage for more spells.
* Since Undying is melee and has low attack speed, the tombstone can be hard to taken down by Undying himself.
* 
Flesh Golem provides Rubick with increased Health pool and a powerful attack modifier.
* 
Rubick can apply the Flesh Golem debuff much more easily as a ranged hero.
* 
Decay is a decent damaging ability, making Rubick somewhat tankier in teamfights.
* 
Soul Rip can be used for extra heal or burst damage.
Additional:
* All abilities from Undying easy to steal to Rubick with 
Spell Steal.
Undying
* Flak Cannon rips through Tombstone's zombies.
Additional:
* 
Flak Cannon enables Gyrocopter to clear the zombies easily.
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.
Undying
* Phantom Lancer's many illusions will easily destroy Tombstone, provided he has sufficient farm.
* He also has no ways of dealing with the illusions, since Decay doesn't steal strength from illusions.
Troll Warlord
* Primal Roar and the slow from Boars make kiting Troll Warlord very easy.
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
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.
Undying
* Familiars will easily be able to kite heroes with a short range or with low attack speed. For example, 
Tiny and Undying have a very hard time killing Familiars.
Undying
* Lifestealer is able to endure Undying, especially in the laning phase, where Undying is strongest. Feast can offset Decay's strength steal for its percentage lifesteal. Rage delays Undying from stealing strength and can help Lifestealer destroy Undying's Tombstone uninterrupted. As well, none of Undying's abilities pierce magic immunity.
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.
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.
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.
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
* 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
* Melee heroes with low mobility can be kited and killed by Viper: 
Treant Protector, Kunkka, 
Alchemist, Troll Warlord, Wraith King, Tiny, 
Sven.
Troll Warlord
* Other heroes that rely on physical attacks to deal damage and not their abilities: Troll Warlord, Sniper, Monkey King, Sven.
Undying
* 
Death Prophet is able to 
Silence Undying up to 6 seconds. Besides, due to Undying's high strength during a team fight, 
Spirit Siphon is a powerful ability against Undying thanks to the percentage health drain.
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.
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
* Heroes that rely on physical damage are ineffective against Dragon Knight due to his high armor: Phantom Assassin,
Bloodseeker, Lifestealer, Troll Warlord, Sven
Undying
* 
Invoker's multiple spells can lock down Undying and disable him from doing much.
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.
Undying
* Mirana can destroy Tombstone, and evade zombies using Leap and Moonlight Shadow's invisibility.
Undying
* Heroes with summons that are destroyed by a fixed number of attacks: Undying's Tombstone, Gyrocopter's 
Homing Missile, and 
Zeus's 
Nimbus.
Undying
* Spectre must chase for kills and relies on movement speed for mobility in fights, and has no way to counter the Tombstone zombies.
* The potency of Soul Rip can be increased from nearby illusions from Haunt.
* Decay will shut down Spectre during the laning phase by effectively cutting down her initial health pool.
Additional:
* Spectre must chase for kills and relies on movement speed for mobility in fights, and has no way to counter the Tombstone zombies.
* The potency of Soul Rip can be increased from nearby illusions, so Undying can use 
Haunt against Spectre.
* Early game Decay will make Spectre easy to shut down in lane.
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.
Undying
* Undying can use Decay not only to reduce Sven's maximum health, but also to reduce the damage he can deal with his ultimate.
* Zombies spawned by Tombstone together with Flesh Golem slow Sven down significantly. Landing Sven's powerful but somewhat slow right-click on Tombstone would be a waste.
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.
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.
Undying
* Undying's Decay is a dangerous ability against Bristleback, as it makes him more vulnerable and reduces his tankiness.
* Undying's Tombstone together with Flesh Golem can slow Bristleback down significantly.
Undying
* Undying's Tombstone will cheerfully chew through treants, incidentally netting you some extra income during fights.
* The above interaction tends to ensure that skirmishes are heavily populated with units, thereby buffing Soul Rip
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.
Undying
* Due to Spirit Breaker's low attack speed, Tombstone is problematic for Spirit Breaker as the zombies summoned from Tombstone apply a stacking movement speed slow, which can significantly reduce Greater Bash's damage.
* Soul Rip and Decay allows Undying and his allies to survive and recover from any incoming ganks by Spirit Breaker.
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.
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.
Undying
* Undying saps strength from heroes with Decay, and Ogre Magi's high strength gain will allow Undying to steal more and more strength, becoming stronger with each use.
* Due to the Strength steal from Decay, Undying is normally very tanky, and has high health, making it harder for Ogre Magi to kill him.
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.
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.
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.
Undying
* Heroes with a slow attack rate will find themselves struggling to take out Tombstone, like Doom.
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.
Troll Warlord
* Mobility heroes will often be rooted by Troll Warlord and unable to escape, like 
Storm Spirit.
Undying
* Anti-Tank heroes like: 
Razor, 
Necrophos, Undying.
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.
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.
Undying
* Generally, any fragile heroes will have a hard time dealing with Undying's tankiness, and even more so if Decay is used on them. Some examples are 
Crystal Maiden and Witch Doctor.
Troll Warlord
* Troll Warlord's melee bash and high attack speed can often help him and his allies win Duels against Legion Commander.
Undying
* Terrorblade can destroy Tombstone with his 
Conjure Image and 
Metamorphosis.
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
* 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.
Undying
* Decay, Soul Rip and Flesh Golem all deal magical damage which ignores Bulwark.
* Decay reduces Mars' natural strength and therefore his health pool, which is what he relies on to trade effectively in lane.
Troll Warlord
* Troll Warlord's high speed attack makes Retaliate deal a lot of damage to him.
Undying
* Decay can be good against Centaur Warrunner, as reducing the health of Centaur can make 
Double Edge risky.
* His zombies do not proc 
Retaliate, as it only procs for regular attacks.
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.
Undying
* Generally, any fragile heroes will have a hard time dealing with Undying's tankiness, and even more so if Decay is used on them. Some examples are Crystal Maiden and Witch Doctor.
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.
Undying
* Huskar's huge damage output and attack speed can get rid of Undying and Tombstone quickly.
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.
Undying
* Tombstone's zombies rarely inhibit Anti-Mage, as he can either Blink away or onto the Tombstone and destroy it.
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.
Undying
* Meepo can quickly destroy Tombstone thanks to 
Divided We Stand.
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.
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.
Undying
* Winter Wyvern cannot handle the Zombies created by Undying's Tombstone very well. In most situations, Zombies will have more movement speed than her.
* Undying can gain one or two easy Decay stacks on an ally in Cold Embrace. The ally will still take the damage as well.
Additional:
* Winter Wyvern cannot handle the Zombies created by Tombstone very well. In most situations, Zombies will have more movement speed than her.
* Undying can gain one or two easy Decay stacks on an ally in Cold Embrace. The ally will still take the damage as well, since it is magical.
Undying
* Heroes without blink mechanisms or spell immunity will have a hard time positioning against
Pit of Malice: 
Sven, 
Tiny, 
Wraith King, 
Dragon Knight, 
Meepo, 
Doom, 
Bounty Hunter, 
Dark Seer, 
Undying, 
Alchemist, 
Legion Commander.
Troll Warlord
*
Atrophy Aura decreases Troll Warlord's damage.
Pit of Malice helps lock down Troll Warlord.
Firestorm and 
Pit of Malice.
*
* Battle Trance disallows Troll from running out of both
