* Inner Beast helps Beastmaster's team destroy Supernova quickly.

* Call of the Wild Hawk can scout Techies as they are placing mines.
* Call of the Wild Boar can clear Proximity Mines.
* The stun of Primal Roar will usually be enough to deal with the squishy Techies before they can try to suicide with Blast Off!.

* 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.

* Juggernaut can attack Remote Mines and trigger Proximity Mines while in Blade Fury.

* Since Techies' skills are all magical damage, casting Fate's Edict immediately upon hearing the warning sound from Proximity Mines and Blast Off! can render Oracle or an ally immune to the burst damage from these skills.
* If timed correctly, Remote Mines can also be countered using the same technique.
Additional:
* Fate's Edict gives 100% magic resistance, which prevents most of Techies' damage and his Fortune's End dispels Stasis Trap root.

* Phoenix does significant magic damage over time which can either be dispelled or negated by Fate's Edict.
* Since Phoenix sacrifices some of his health to cast abilities it makes him very vulnerable to Oracle's burst potential

* 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.

* Thanks to Counterspell Anti-Mage can fight Techies head on and trip multiple mines once the late game hits.

* Heroes that deal damage over time will also fail to bring down Abaddon and his allies, such as Huskar, Venomancer, or Phoenix.

* Borrowed Time's automatic activation will help Abaddon survive a massive Remote Mines explosion; however, the damage from a single one can kill him if his HP is low enough.
Additional:
* Aphotic Shield makes it less likely for allies to be killed by mines.
* Because they explode in very short intervals, a stack of Remote Mines will always trigger Borrowed Time, making them impossible to kill Abaddon unless his resistances are lowered enough or Abaddon is affected by Break.
* Abaddon can easily dispel the long-lasting root of Stasis Trap on himself and on an ally, while at the same also providing protection against the other mines' damage.

* Exorcism's ghosts will automatically clear all Proximity Mines revealed when Death Prophet walks near them, provided that the ghosts do not have a specific target at that time.

* 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.

* Lifestealer's Rage lets him clear Remote Mines and Proximity Mines with proper vision.
Additional:
* Rage protects Lifestealer from all of Techies' magic damage and disables and dispels Stasis Trap's debuff .
* Usually teams will have a hard time pushing high-ground against Techies, but Lifestealer can just pop Rage and walk uphill without fear of Techies.

* 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.

* In general, heroes such as Lion, Silencer, Skywrath Mage, Sven, Ogre Magi and others with reliable disables are crucial to killing Techies before they can suicide.

* 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.

* With Dark Ascension Night Stalker gains unobstructed vision during night-time allowing him to easily detect mines if he has a Gem of True Sight, but Night Stalker is a melee hero so he has to use Quelling Blade to safely defuse Remote Mines and Stasis Trap.
* Dark Ascension also allows Night Stalker to fly over Proximity Mines without triggering them.
* Crippling Fear is effective in stopping Techies from using Blast Off! and Void is effective in stopping them from running to the safety of their mines.

* 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.

* 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.

* In general, heroes such as Lion, Silencer, Skywrath Mage, Sven, Ogre Magi and others with reliable disables are crucial to killing Techies before they can suicide.

* Chemical Rage kills Phoenix very quickly in Supernova.

* 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.
Additional:
* 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.

* Although Phoenix has many ways to disable a Blink Dagger, the high cooldown of all of his spells makes them not as reliable for this. Also, his spells cost him a lot of health to use, making it easy for him to get nuked down.
* Waning Rift prevents Phoenix from using Supernova to refresh himself, giving Puck's team time to finish Phoenix off, or allow Puck to burst him down.
* Dream Coil prevents Phoenix from using Icarus Dive without consequences. Waning Rift and Dream Coil are also able to cancel his Sun Ray, which is his main source of damage in the late game.

* Due to Reincarnation and his general tankiness he can live through at least one major Remote Mines stack or Blast Off!.
* Special mention for a bug with his Aghanim's Scepter. If enemies get killed from your mines under the effect of "Wraith Delay", they get denied instead of crediting the kill to you.
Additional:
* Wraith King is not afraid to walk into mines, whenever he goes with his Reincarnation ready.

* Due to Fervor and Battle Trance, Troll Warlord is one of the best heroes to deal with Supernova.

* Techies spends lots of time standing still planting stacks of Land Mines away from creep waves.
* Sacred Arrow can be used to scout hidden Land Mines among trees and at uphill places. It can also be used to catch Techies while he's planting them.
* If Techies is hit with a Sacred Arrow, he can be killed before he has a chance to use Blast Off!.
* Mirana has a high attack range to destroy his traps from a safe distance.

* 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.

* 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.

* 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.
Additional:
* 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.

* Plague Wards may reveal a hiding Techies. If there's a sentry nearby, they may also reveal a stack of mines hidden in a juking spot.

* As long as Batrider is under the effects of Firefly, he can safely fly over mines.
* Sticky Napalm also punishes low mobility heroes that like to kite, such as Techies, by lowering their turn rate dramatically. This can also potentially delay Techies' Blast Off! if Techies tries to cast Blast Off! in a direction he's not currently facing.
Additional:
* As long as Batrider is under the effect of Firefly, he can safely fly over Proximity Miness (He does not receive vision over the mines).

* Phoenix's limit AoE, damage-over-time abilities give Io plenty of time to save allies with Relocate.

* Due to the fact that Lightning Bolt gives True Sight, Zeus is able to reveal where Techies' remote mines are. He can also cancel Blast Off! due to the mini-stun on the Lightning Bolt.

* 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.

* Lil' Shredder will make quick work of Supernova.
* Mortimer Kisses can easily hit a Phoenix using Sun Ray.

* Equipped with Necronomicon 3, Sentry Ward or a Gem of True Sight, Nature's Prophet can use Teleportation to position himself outside the reach of Techies' Remote Mines to clear them.
* Treants are useful in clearing Land Mines and Remote Mines.

* Heroes with summons like Broodmother,Enigma, Invoker, Nature's Prophet, Lycan, Visage;or illusions, like Naga Siren, Phantom Lancer, Terrorblade are effective at keeping the choke points and rune spawns safe from Proximity mines in the early game.

* Heroes with summons like Broodmother,Enigma, Invoker, Nature's Prophet, Lycan, Visage;or illusions, like Naga Siren, Phantom Lancer, Terrorblade are effective at keeping the choke points and rune spawns safe from Proximity mines in the early game.

Additional:
* He can send wolves to defuse Proximity Mines, and he can catch up Techies and kill him before they can deny themselves. Even if the suicide is successful, Lycan can still survive because of his tankiness.

* Heroes with summons like Broodmother,Enigma, Invoker, Nature's Prophet, Lycan, Visage;or illusions, like Naga Siren, Phantom Lancer, Terrorblade are effective at keeping the choke points and rune spawns safe from Proximity mines in the early game.

* 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.

* Slow heroes that have a hard time escaping the Echo Stomp radius: Crystal Maiden, Pudge, Techies.

* In general, heroes such as Lion, Silencer, Skywrath Mage, Sven, Ogre Magi and others with reliable disables are crucial to killing Techies before they can suicide.

* Techies struggles early game against heroes with naturally large strength and health regeneration such as Pudge, Axe or Ogre Magi, as the player is forced to lay down more mines than usual to kill these bulkier heroes.

* Heroes with summons like Broodmother,Enigma, Invoker, Nature's Prophet, Lycan, Visage;or illusions, like Naga Siren, Phantom Lancer, Terrorblade are effective at keeping the choke points and rune spawns safe from Proximity mines in the early game.

* Heroes with summons like Broodmother,Enigma, Invoker, Nature's Prophet, Lycan, Visage;or illusions, like Naga Siren, Phantom Lancer, Terrorblade are effective at keeping the choke points and rune spawns safe from Proximity mines in the early game.

Additional:
* Techies' mines can be destroyed by Terrorblade's spammable illusions.
* Terrorblade can push without the fear of dying to mines; he can instead use his illusions to push.

* 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.

* Heroes with flying vision such as Visage, Beastmaster, Keeper of the Light, or Night Stalker can scout your mines from outside their trigger radius.

* 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.

* In general, heroes such as Lion, Silencer, Skywrath Mage, Sven, Ogre Magi and others with reliable disables are crucial to killing Techies before they can suicide.

* Phantasm's illusions can be used to push towers and force Techies to detonate Remote Mines.
* Phantasm's illusions can be used to sweep Proximity Mines and Stasis Traps.
* Chaos Knight can easily kill a lone Techies before they Blast Off!.
