Troll Warlord
* Primal Roar and the slow from Boars make kiting Troll Warlord very easy.
Phoenix
* Inner Beast helps Beastmaster's team destroy 
Supernova quickly.
Troll Warlord
* Melee heroes with low mobility can be kited and killed by Viper: 
Treant Protector, 
Kunkka, 
Alchemist, 
Troll Warlord, 
Wraith King, 
Tiny, 
Sven.
Phoenix
* 
Corrosive Skin gives Viper additional resistance to Phoenix's magical damage, and since they deal damage over time, Phoenix would be constantly afflicted by his passive's own debuff, making him not an ideal target for Phoenix's harassment. Phoenix's abilities also constantly drain its own health away, becoming more vulnerable to 
Poison Attack.
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.
Phoenix
* 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.
Phoenix
* Tempest Double, Magnetic Field's attack speed bonus, and Arc Warden's high attack range will easily destroy a Phoenix using Supernova much faster than usual.
* Phoenix is very weak against pushers, especially those like Arc Warden who can kill him easily, as his skillset works best in teamfights.
Additional:
* His 
Tempest Double is not an illusion, but rather a full hero unit, which effectively reduces half of the Supernova's health. His 
Magnetic Field can tremendously boost his attack speed, allowing him to destroy Supernova in no time even when he's affected by 
Fire Spirits.
Phoenix
* Ursa can easily unleash a number of attacks in an incredibly short amount of time, easily destroying the Supernova in a couple of seconds regardless of Fire Spirits' debuff. His 
Enrage also dampens any damage Phoenix might toss at his direction, as well as remove any debuffs Phoenix may place on him.
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.
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
* 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.
Phoenix
* Marci can destroy Supernova by herself with Unleash at any stage of the game.
* Phoenix is squishy hero with low armor and is very vulnerable for Rebound and Sidekick at the laning stage.
Phoenix
* Chemical Rage kills Phoenix very quickly in Supernova.
Phoenix
* Phoenix's limit AoE, damage-over-time abilities give Io plenty of time to save allies with Relocate.
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.
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.
Phoenix
* Silencer will most likely disrupt an initiation with his ultimate, 
Global Silence, prevent escape with his 
Last Word, and if Phoenix happens to die to him (or near him) enough times, he would sap enough of Phoenix's much needed Intelligence to make him a stronger foe and Phoenix with less mana than it already had.
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
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.
Phoenix
* Phoenix constantly depletes its own health due to the health costs of its abilities. Unlike heroes that have a similar mechanic, Phoenix does not benefit from low health, nor does it really have a countermeasure for it. As such, Phoenix is a very vulnerable target for Necrophos to prey on, especially when caught off guard before it can cast Supernova.
Additional:
* Necrophos becomes a bigger threat the lower one's health gets, and unfortunately for Phoenix, most of its spells have noticeable health costs. Those costs, coupled with his 
Heartstopper Aura, means that staying in a teamfight for too long under Necrophos' presence will make Phoenix a more valid target for his ultimate, with its stun completely preventing any form of retaliation or protection. Necrophos players are also likely to buy more durability items such as 
Hood of Defiance, making him more able to withstand Phoenix's damage despite having no escape mechanisms.
* However, it is also important to remember that a Scepter-upgraded Supernova can help protect an ally from his ultimate.
Phoenix
* As a hero with uncommon traits, 
Phoenix's abilities require more health than mana. It is advised for Rubick to purchase health regeneration items such as 
Tranquil Boots, 
Urn of Shadows or Hood of Defiance to keep up with the HP loss.
* Phoenix's signature Supernova, if casted successfully, can turn a teamfight around if being stolen.
* The initial lift and the following crowd control from the drop of 
Telekinesis can protect the egg from being attacked if casted right before Supernova with quick fingers.
* A successfully reborn Supernova refreshes the cooldown of Telekinesis as well as 
Fade Bolt, so don't hesitate to spam both of them before Supernova with the reasons mentioned above.
* Supernova has a stun range of 1200, which requires Rubick to have Level 3 
Arcane Supremacy at least to exceed its range. Consider buying 
Aether Lens or 
Blink Dagger to help with positioning.
* It is not possible to cast Supernova (as of 7.31c) with 
Aghanim's Shard's extra 
Sun Ray even with both spell stolen, since Sun Ray takes up two stolen ability slots.
* 
Icarus Dive is a useful repositioning ability for scouting, initiation or escaping.
* Fire Spirits aids with Rubick farming given enough HP regeneration. In early skirmishes, the stolen ability can slow the attack speed of the enemy team to a crawl.
* Combined with Fade Bolt, both the attack damage and attack speed of the enemy team are reduced if they have no source of dispel, effectively nullifying their physical attack damage.
* Sun Ray thrives in and after a teamfight by damaging enemy heroes and healing allies at the same time.
* Rubick can interrupt both Icarus Dive and Sun Ray by casting Telekinesis.
Phoenix
* Although Phoenix has many ways to disable a Blink Dagger, the high cooldown of all of its spells makes them not as reliable for this. Also, its spells cost a lot of health to use, making it easy to get nuked down.
* Waning Rift prevents Phoenix from using Supernova to refresh itself, giving Puck's team time to finish it off, or allow Puck to burst Phoenix down.
* Dream Coil prevents Phoenix from using Icarus Dive without consequences. Waning Rift and Dream Coil are also able to cancel Sun Ray, which is its main source of damage in the late game.
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.
Phoenix
* 
Lil' Shredder will make quick work of Supernova.
* 
Mortimer Kisses can easily hit a Phoenix using Sun Ray.
Phoenix
* Heroes that deal damage over time will also fail to bring down Abaddon and his allies, such as 
Huskar, 
Venomancer, or Phoenix.
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.
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
* 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.
Phoenix
* Heroes that depend on disrupting fights with ability combos or big ultimate abilities are vulnerable to the long stun of Fiend's Grip: 
Disruptor, 
Death Prophet, 
Enigma, Faceless Void, 
Invoker, 
Lich, 
Magnus, 
Mars, 
Medusa, 
Outworld Destroyer, Phoenix, 
Puck, 
Queen of Pain, Shadow Fiend, Treant Protector, 
Underlord, 
Winter Wyvern, 
Witch Doctor, 
Zeus.
Phoenix
* Heroes with hiding abilities can protect disabled allies: Outworld Destroyer, 
Shadow Demon, 
Tusk, Phoenix with 
Aghanim's Scepter.
Troll Warlord
* Troll Warlord's high speed attack makes Retaliate deal a lot of damage to him.
Phoenix
* 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.
Phoenix
* Silence (and mana burns) will be a persistent problem for Phoenix, as it is heavily reliant on its abilities whether defensively or offensively, so heroes like Death Prophet, 
Skywrath Mage, and even 
Nyx Assassin must be closely observed to prevent being shut down by these heroes.
* Hexes are a greater threat to Phoenix as they also disable items, preventing Phoenix from dispelling the debuff on its own.
Troll Warlord
* Other heroes that rely on physical attacks to deal damage and not their abilities: Troll Warlord, Sniper, Monkey King, Sven.
Phoenix
* Silence (and mana burns) will be a persistent problem for Phoenix, as it is heavily reliant on its abilities whether defensively or offensively, so heroes like Death Prophet, Skywrath Mage, and even Nyx Assassin must be closely observed to prevent being shut down by these heroes.
* Hexes are a greater threat to Phoenix as they also disable items, preventing Phoenix from dispelling the debuff on its own.
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.
Phoenix
* Heroes with blink or movement abilities, which are disabled by Pounce's leash: Anti-Mage, 
Earth Spirit, Faceless Void, Magnus, Mirana, Monkey King, Morphling, 
Pangolier, Phantom Assassin, Phoenix, Puck, Queen of Pain, Riki, 
Sand King, 
Spirit Breaker, 
Timbersaw, Tusk.
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.
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
* Heroes who rely heavily on melee attacks and lack early spell immunity are easily blocked and interrupted by Ink Swell: Lycan, Ursa, Troll Warlord.
Phoenix
* Earthbind can prevent Phoenix from using Icarus Dive, the only escaping mechanism of this hero.
* Heavy burst damage from Poof can easily kill Phoenix even when it slows down all the Meepos with Fire Spirits.
* Meepo's clones destroy the Phoenix Sun from Supernova in no time, even when they are slowed down by Fire Spirits.
* Meepo's naturally high magic resistance gives Phoenix a hard time with bursting him down. He can even turn the tide if Icarus Dive is on cooldown.
Additional:
* Meepo is unlike any other multi-unit enemy Phoenix may face in the battlefield. Unlike illusion-based heroes like Phantom Lancer or 
Chaos Knight, Meepo's clones are not illusions, meaning they can deal full damage to the Phoenix Sun if all four (or five) are present.
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.
Phoenix
* Spiked Carapace reacts on any of the damage over time from Phoenix's abilities and can interrupt Sun Ray and Icarus Dive.
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.
Phoenix
* Huskar's high attack speed can counteract Fire Spirits, and easily destroy the Supernova.
Additional:
* 
Berserker's Blood will let Huskar easily face down a Supernova with increased attack speed.
* Icarus Dive may not be an easy escape from Huskar either as he can chase Phoenix during it with 
Life Break if Huskar times it right.
* However, Phoenix can buy items which can
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.
Phoenix
* 
Song of the Siren does not affect Supernova, which allows her and her team to focus the egg while the enemy team is affected by sleep.
* Phoenix cannot use Icarus Dive for escaping when rooted by 
Ensnare.
* However, Phoenix has many area-of-effect abilities that allow him to clear Naga Siren's illusions from 
Mirror Image.
Phoenix
* Sand King and Phoenix have many tools to deal with multiple enemies at once, which will work well against a crowd of illusions.
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.
Phoenix
* Heroes with spell immunity-granting spells will render Phoenix useless against them, as Phoenix has almost no spell immunity-piercing ability, other than the stun at the end of Supernova: Lifestealer, Juggernaut.
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
* 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.
Phoenix
* Primal Beast is disarmed during Trample so will be unable to destroy a Supernova no matter how close it is to him.
* The same ability can also be used to save allies with the help of an Aghanim's Scepter.
* Sun Ray will do thousands of damage to Primal Beast if surviving a full channel time due to his high health scaling for the ability.
* Icarus Dive is a fantastic way to escape Primal Beast after he has used Onslaught.
* Phoenix has a naturally very high health pool making it hard for Primal Beast to deal with him with his magical damage.
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.
Phoenix
* Fire Spirits applies a severe attack speed slow, severely hindering Phantom Assassin's damage output.
* Phantom Assassin cannot cast Phantom Strike on Phoenix during Supernova.
Additional:
* While her 
Phantom Strike does give limited extra attack speed, she cannot use the ability against the Phoenix Sun, and while her Blur may protect her from attacks, Phoenix's strong magical DPS burns away her small health pool quickly, and the attack speed slow makes her unable to fight back (provided she has no source of spell immunity).
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.
Phoenix
* Phoenix will usually be on the sidelines or further back ready to use Sun Ray. Even after Magnus successfully uses Reverse Polarity and skewer Phoenix's teammates, Phoenix can usually counter-initiate using all of its abilities.
Troll Warlord
* Troll Warlord's melee bash and high attack speed can often help him and his allies win Duels against Legion Commander.
Phoenix
* Heroes who can hide the Dueled target (Outworld Destroyer, Shadow Demon, Tusk, Phoenix with Aghanim's Scepter etc).
Additional:
* Legion Commander relies on her powerful attack and her 
Duel to be effective. But if Phoenix gets the jump on her first, she can find herself severely slowed, taking heavy damage, and find herself unable to Duel a burning Supernova.
* It must be noted that 
Press the Attack will both dispel the attack slow of Fire Spirits and grant her or whoever she targets bonus attack speed. This allows her to easily destroy a Supernova if caution is not taken to prevent this from occurring. As such, it would be a better decision to simply avoid a farmed or skilled Legion Commander instead of attempting to overpower her.
* If an ally is caught by Duel, Phoenix can use Sun Ray to heal the ally and damage Legion Commander, possibly swinging the Duel in their team's favor. Or with Aghanim's Scepter, Phoenix can save an ally from dying in Duel with Supernova and cancel the Duel as well.
Phoenix
* Phoenix's AoE abilities can prove troublesome for Phantom Lancer.
* Fire Spirits dramatically reduces Phantom Lancer and his illusions' attack speed.
* Icarus Dive's movement speed reduction makes retreating difficult.
* Supernova burns away illusions, and is invulnerable to attacks from illusions.
Phoenix
* Phoenix's large damage over time with Icarus Dive and Fire Spirits can kill Chen's allies before he can use Hand of God.
* Phoenix naturally buys 
Spirit Vessel, which allows him to reduce healing from 
Divine Favor and 
Hand of God.
* Phoenix's Supernova cannot be damaged by Chen's creeps, and their normal speed means they will often not be able to kill Phoenix whenever he uses Supernova.
Additional:
* Not only Phoenix is able to disrupt Chen's jungling with Fire Spirits, but its high damage over time can also force Chen to use Hand of God prematurely, potentially wasting any chance to save his allies during teamfights.
* Creeps' damage and attack speed are very abysmal, so Chen often cannot kill Phoenix whenever it casts Supernova.
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.
Phoenix
* Icarus Dive and Supernova can destroy the tree Monkey King is standing on.
* Fire Spirits reduces Monkey King's attack speed, preventing Monkey King from building up Jingu Mastery.
* Supernova can be casted next to Wukong's Command, forcing Monkey King to step away of it or to withstand its massive AOE damage
Additional:
* Icarus Dive, Sun Ray, and Supernova all destroy trees that Monkey King relies on to use his ability 
Tree Dance. If you spot him, you can quickly Icarus Dive in his direction and then follow up with Fire Spirits and Supernova. If you manage to cut the tree he is on, he will be stunned for 4 seconds and will be forced to take a lot of damage. However, most Monkey King players tend to build attack speed items to make use of their passive, 
Jingu Mastery, so a battle against a farmed Monkey King will depend on who gets the jump on the other first.
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.
Phoenix
* Her 
Refraction charges can and will be easily burned away by Phoenix's damage over time abilities, and 
Meld can't protect her from Phoenix's AoE abilities, even without detection.
Additional:
* Phoenix's abilities target and deals damage over time, making them a threat against Meld and Refraction. His abilities' nature makes them pretty hard to correctly land on the target, but that is not a problem against a Templar Assassin that needs to stand still during Meld.
* Icarus Dive allows Phoenix to shrug off the slow from her trap and make an easy escape from her ambush.
* As Templar Assassin relies on her quality-over-quantity bursting attacks to make quick work on fragile target, Fire Spirits' attack speed reduction can cripple her ability to deals any damage during combat. With the debuff applied in early-mid game, a Meld-breaking hit from her is significantly slowed to the point that her target can travel a safe distance before she even lands the hit.
* Sun Ray has a quick damage tick and will burn through her Refraction in no time.
* Supernova deals damage over time in an incredibly large area, and again with her quality-over-quantity style, she may not be able to attack quickly enough to break through the Phoenix Sun by herself. (not to mention the debuff from Fire Spirits) This can lead to a failed ganking attempt or even a turnaround.
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.
Phoenix
* Fire Spirits greatly reduces Slardar's already low starting attack speed (which Bash of the Deep relies on), making the laning phase very hard for him and discouraging Slardar from aggressively threatening lane kills.
* Supernova, ignoring Phoenix's lack of armor and Slardar's high damage single hits, is extremely hard for Slardar to take down on his own, especially after being hit by Fire Spirits.
* Icarus Dive is one of the longest distance escape spells in the game, and can help a good Phoenix escape from Slardar before he gets a Blink Dagger. However, the high cooldown means Phoenix is vulnerable to backstabs from any roamers after said spell is used.
* Slardar can interrupt an Icarus Dive from completing the flight with both of his stuns, however, likely leading to death if Supernova is on cooldown.
* A lot of the items a Phoenix builds throughout the game naturally counter Slardar. 
Shiva's Guard, Heaven's Halberd and 
Eul's Scepter of Divinity all stall Slardar's normal attacks in some way, while Spirit Vessel's percentage-based damage is good against his innate durability.
Phoenix
* Fire Spirits does damage over time, preventing Faceless Void from backtracking the full damage with Time Walk.
* Fire Spirits applies a big attack speed slow, stopping Faceless Void from doing many attacks while in Chronosphere.
* Sun Ray can heal allies and damage Faceless Void from outside Chronosphere.
* Supernova can be cast outside of Chronosphere, forcing Faceless Void to step away from it, lest he'll take a lot of damage
Phoenix
* Due to Spirit Breaker's low attack speed, Supernova is problematic for Spirit Breaker to take down, and even more so with Fire Spirits debuff applied.
Phoenix
* Supernova negates Kunkka's combo entirely, as it can't be affected by spells while using Supernova.
* Icarus Dive also allows Phoenix to dodge Ghostship and Torrent.
Phoenix
* Supernova allows Phoenix to save himself (or an ally, with Aghanim's Scepter) through 
Echo Slam. Earthshaker will also have a difficult time destroying the supernova, due to his low base attack time and poor agility.
* Icarus Dive can pass through Earthshaker's 
Fissure.
* Most of Phoenix's abilities disable Earthshaker's Blink Dagger for a good period of time due to the damage-over-time nature of its spells.
Phoenix
* Clockwerk being confined in his own Power Cogs means Clockwerk is unable to quickly escape from Phoenix's Sun Ray and Supernova.
* Sun Ray will also heal the enemy Clockwerk is fighting, making it unlikely for Clockwerk to take an enemy down with him.
* For the same reasons, Phoenix also makes a powerful ally for Clockwerk when the situation is reversed.
Phoenix
* Sand King has nothing to deal with Supernova, as none of his spells are effective.
* The damage-over-time abilities of Phoenix disable Sand King's Blink Dagger very often.
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.
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.
Phoenix
* Lone druid's bear attacks on Phoenix's Supernova Egg don't increase the hit count. Given that Lone Druid's main hero often doesn't have much farm, the Supernova Egg is less likely to get killed.
Phoenix
* Phoenix's Supernova cannot be damaged by Familiars.
* In the early and mid game, Sun Ray won't deal enough damage to be reduced by Gravekeeper's Cloak.
* Once Sun Ray deals enough damage to protect Visage, a layer of Gravekeeper's Cloak is burnt every 0.2 seconds.
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.
Phoenix
* Heroes with high health especially Strength heroes will take more damage on Sun Ray: Axe, 
Pudge, 
Bristleback, Mars.
Phoenix
* Heroes that are able to slow Tiny's attack speed, like Tusk and Phoenix, will greatly limit his Physical damage output.
Troll Warlord
* Mobility heroes will often be rooted by Troll Warlord and unable to escape, like 
Storm Spirit.
Phoenix
* Heroes who depend on attacks (such as Shadow Fiend or Drow Ranger) can be nullified by Fire Spirits' attack speed slow.
Phoenix
* Heroes with high health especially Strength heroes will take more damage on Sun Ray: Axe, Pudge, Bristleback, Mars.
Phoenix
* Heroes who depend on attacks (such as Shadow Fiend or Drow Ranger) can be nullified by Fire Spirits' attack speed slow.
Phoenix
* Heroes with slow movement speeds and small health pools (supports like 
Crystal Maiden or Witch Doctor) are easy targets for Phoenix. Should they be inflicted by its DOT debuffs, they will be very quickly killed without even getting a chance to fight back.
Phoenix
* Phoenix with Supernova
* 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
Phoenix
* 
Void can interrupt Icarus Dive.
* His 
Crippling Fear's silence will shutdown a spell caster Phoenix.
* However, Phoenix punishes Night Stalker with Supernova because it will turn night into day, and it has a higher priority than 
Dark Ascension, effectively canceling the passive bonuses Night Stalker gets from 
Hunter in the Night.
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.
Phoenix
* Phoenix turns night to day, overriding Dark Ascension during Supernova.
Phoenix
* Since all of Phoenix's abilities (except for Supernova) have health costs, heroes like 
Ancient Apparition or 
Necrophos can turn Phoenix's abilities against it. However, Supernova does completely protect Phoenix from 
Ice Blast.
Phoenix
* Icarus Dive helps Phoenix escape from Cold Feet.
* However, all of Pheonix's basic abilities do cost health, which can be harmful under the effects of Ice Blast.
* Supernova can save Phoenix from Ice Blast.
Additional:
* Supernova with or without Aghanim's Scepter allows to save ally or himself through Ice Blast.
* Icarus Dive quickly escapes from 
Cold Feet.
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.
Phoenix
* Icarus Dive quickly escapes from Shadow Demon abilities, especially 
Demonic Purge.
* Phoenix AoE abilities remove Shadow Demon's illusions created by 
Disruption.
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.
Phoenix
* Heroes with slow movement speeds and small health pools (supports like Crystal Maiden or Witch Doctor) are easy targets for Phoenix. Should they be inflicted by its DOT debuffs, they will be very quickly killed without even getting a chance to fight back.
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.
Phoenix
* Heroes with high health especially Strength heroes will take more damage on Sun Ray: Axe, Pudge, Bristleback, Mars.
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.
Phoenix
* Heroes with strong area damage to destroy Phantasm illusions: Axe, Ember Spirit, Legion Commander, Phoenix
Phoenix
* Anti-Mage dispels Phoenix's slows with Manta Style.
* Anti-Mage can Blink directly next to Supernova, giving him more time to destroy the egg.
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.
Phoenix
* Juggernaut's high attack speed lets him destroy a Supernova easily. He can even attack a Supernova during Blade Fury with his regular attacks.
* 
Blade Fury protects Juggernaut from all of Phoenix's spells (except Supernova, which pierces spell immunity).
* Blade Fury can also dispel the attack speed slow from Fire Spirits and the movement speed slow from Icarus Dive.
* Phoenix's Icarus Dive will not protect it from Omnislash unless it dives into creeps, and Phoenix's low armor makes for an easy kill.
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.
Phoenix
* Phoenix expends health to use its abilities, making it a good target for Thirst.
* Rupture deals heavy damage against Icarus Dive.
Additional:
* Although 
Blood Rite can be easily avoided, if it does hit, its lengthy silence and pure damage can be a severe punishment for a slow, unobservant, or simply unfortunate Phoenix.
* His 
Rupture can turn Icarus Dive into a suicide option, and it cannot be dispelled, meaning even if Phoenix completes a Supernova, choosing to Dive may just cut its health back down.
* And finally, due to Phoenix's health costs, too much careless ability spamming may just put Phoenix into Bloodseeker's vision through 
Thirst, making it a very tempting ganking target.
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
* 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.
Phoenix
* Sun Ray allows Phoenix to heal any allies caught in Berserker's Call while burning away Axe's high HP at the same time.
* Icarus Dive and Fire Spirits puts Axe's Blink Dagger on cooldown.
* Axe's slow attack speed makes it difficult for him to destroy Supernova on his own.
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.
*
*
Phoenix
* Phoenix does significant magic damage over time which can either be dispelled or negated by Fate's Edict.
* Oracle's burst damage potential can prove lethal to Phoenix, as they already have to sacrifice health to cast their basic skills.
