Kunkka, 
Alchemist,

Treant Protector
* 
Corrosive Haze will reveal Treant Protector even when he is under the effects of Nature's Guise.
Techies
* Familiars can fly over the mines, rendering them safe from damage of Techies's mines. Visage can also use Familiars to check for mines on the map.
* Techies's low attack speed and damage will give them a hard time in destroying Visage's Familiars, and that can become even worse if they are affected by 
Grave Chill.
* 
Gravekeeper's Cloak allows Visage to survive Damage from Techies's mines.
Techies
* 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.
Additional:
* 
Borrowed Time's automatic activation will help Abaddon survive a field of Proximity Mines or a Blast Off combo. However, the damage from a single mine can kill him if his HP is low enough.
* 
Aphotic Shield's can easily break Techies' Etheral Blade combo.
Techies
* 
Fate's Edict gives 100% magic resistance, which prevents most of Techies' damage.
* Oracle's 
Fortune's End dispels Reactive Tazer buff from Techies allowing him to be attacked. However, Reactive Tazer will instantly perform the area of effect disarm that is normally applied at the end of the duration.
* Fortune's End will also dispel Blast Off silence, Techies' Etheral Blade, Proximity Mines' magic resistance reduction, and Sticky Bomb's slow. However beware that it will only dispel Sticky Bomb's first or second instance of slow and not the damage, which will trigger as normal.
Additional:
* Oracle can negate all of Techies' skills with Fate's Edict, as they are all magic damage. Fate's Edict can also be used to search and trigger 
Proximity Mines when crossing mined territory.
* Oracle can dispel 
Reactive Tazer off Techies, as well as the silence from 
Blast Off!, with Fortune's End.
* Oracle can further delay Techies' burst damage capability with False Promise.

Techies
* 
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.
Techies
* Rage protects Lifestealer from all of Techies' abilities. Reactive Tazer's disarm will also not work on Lifestealer under Rage.
* Rage can also be used to trigger Techies' Proximity Mines safely.
Additional:
* Lifestealer's 
Rage lets him clear Proximity Mines without taking damage, and allows him to hit heroes whom Techies has used Reactive Tazer on.
Treant Protector
* Living Armor can be destroyed quickly with Ion Shell.
Treant Protector
* Light Strike Array and Dragon Slave allows Lina to destroy trees, countering 
Nature's Guise and Eyes in the Forest.

Techies
* 
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.
* Death Prophet is a natural 
Eul's Scepter of Divinity carrier, meaning she can easily escape a Blast Off initiation.
Techies
* Shadow Demon's spammable illusions can be used to scout Techies' Proximity Mines. The illusion of your carries can be even used to trick Techies into detonating his precious Remote Mines.
Techies
* 
Refraction can be very useful in safely neutralizing Proximity Mine fields, or absorbing Techies' Blast Off combo.
Treant Protector
* All of Treant Protector's abilities are worth stealing, and Rubick is able to cast them with no animation time.
Treant Protector
* Not only are all of Timbersaw's active abilities capable of cutting down trees, but 
Whirling Death and 
Timber Chain also require it to be effective, counteracting both Treant Protector's Nature's Guise and Eyes in the Forest abilities.
Additional:
* Timbersaw can use his plethora of tree cutting abilities to level entire sections of the forest, making hiding in the trees more difficult for Treant Protector and his team.
* Timbersaw can easily cut down Treant Protector's Eyes In The Forest once his team has detection. He may even do it unknowingly due to the sheer destructive and chaotic nature of his abilities.
Techies
* Slow heroes that have a hard time escaping the Echo Stomp radius: 
Crystal Maiden, 
Pudge, Techies.

Techies
* Wraith King is not afraid to walk into mines, whenever he goes with his Reincarnation ready.
Treant Protector
* 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.
Techies
* 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.
Treant Protector
* Treant Protector grants protection against his attacks with Living Armor and his ultimate, Overgrowth is a massive AoE disarm and root that pierces spell immunity, causing trouble to Lycan. You will find yourself in need of an ally's dispel or forced to pop 
Black King Bar for its dispel.
Additional:
* Lycan has no kind of teleport, being only able to walk, and heavily relies on his attacks. As Overgrowth roots and disarms the targets, Lycan can't do much in an overgrowth field.
Techies
* Juggernaut can trigger Proximity Mines while in 
Blade Fury, and can walk away from a initiation with Blast Off if Blade Fury is activated before the silence.
* Juggernaut ignores Reactive Tazer when he uses

Bane, 
Pugna, 
Tusk, Winter Wyvern, 
Io, Underlord, Treant Protector and 
Keeper of the Light.
Techies
* 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.
Treant Protector
* Overgrowth has a great duration, which prevents the units caught from attacking, moving and Blinking. Heroes like 
Storm Spirit, 
Mirana, 
Anti-Mage and others won't be able to do much if they're caught.
Treant Protector
* If Storm Spirit is caught in an Overgrowth, he is shut down.
* With the exception of 
Electric Vortex, he won't be able to cast any relevant skill.
Techies
* If Storm Spirit isn't careful, he could fall into a trap set by Techies and another hero acting as bait.
* Stasis Trap roots Storm Spirit for 2/3/4/5 seconds and Blast Off! silences for 4/5/6/7 seconds, which effectively prevents Storm Spirit from using 
Ball Lightning to escape for a lengthy duration.
Treant Protector
* Treant can give chase should Hoodwink attempt to 
Scurry away, and 
Nature's Grasp can slow her down so Treant Protector's teammates can pin Hoodwink down.
Techies
* Remote Mines are frequently placed in trees, and can thus kill an unwary Hoodwink should she Scurry away due to her low HP pool.
* Blast Off! can clear out trees, denying the tactical advantages from Scurry.

Blink Strike even through her spell immunity.
* Living Armor reduces Phantom Assassin's physical damage whenever she attempts to gank an allied hero.
Techies
* Morphling usually has low max health due to shifting strength into agility, which combined with Blast Off's silence will prevent him from using 
Waveform and 
Adaptive Strike (Strength), leaving him defenseless and making him an easy target to burst down.
Techies
* After using Snowball, Tusk can't control where he's going, allowing Techies to make him roll onto mines.
Treant Protector
* Nature's Grasp severely slows down Spirit Breaker, reducing effects of Charge of Darkness and Greater Bash.
* Living Armor can mitigate a large portion of Spirit Breaker's damage since his attacks are slow.
* Treant Protector can also counter-initiate against Spirit Breaker with 
Leech Seed, Overgrowth and with his root from {I|Aghanim's Shard
* 
Aghanim's Scepter gives Treant Protector access to Eyes In The Forest ability, which allows him to turn trees into wards that provide vision, allowing him to keep his allies warned about Spirit Breaker's attempts to gank them. Eyes In The Forest will also trigger Overgrowth if Spirit Breaker is in range of the tree affected by it.
Additional:
* Spirit Breaker's slow attacks cannot harm a hero shielded by Living Armor.
Treant Protector
* Clinkz will often roam the map alone, and Treant Protector's Nature's Guise allows him to set up kills with his allies on Clinkz from invisibility.

* Blast Off silences Chaos Knight, stopping him from using his disables and allowing his teammates to walk away from his heavy damage.
* Reactive Tazer will disarm all of Chaos Knight's illusions even if he has activated his Black King Bar.
Techies
* Techies can easily catch Chen off guard and kill him quickly with Blast Off! and 
Ethereal Blade combo, especially because Blast Off! can silence Chen and stun him when upgraded with 
Aghanim's Shard.
* However, Chen's converted creeps can trigger Proximity Mines, wasting them.
Techies
* Reactive Tazer can lock multiple Meepos in place and prevent them from Poofing.
* Proximity Mines, 
Sticky Bomb and Blast Off! can deal heavy magic damage to multiple Meepos.

Techies
* Techies can turn his tree jumping ability against him, by placing Proximity Mines that will detect him near trees, and then destroying the trees around him with Blast Off, stunning him and dealing high damage, on top of him being silenced when the stun expires.
* Monkey King's mobility is also severely limited around Techies' mines as he will almost always trigger them due to the cooldown time between tree jumps. Monkey King will be forced to take mine damage or escape with 
Primal Spring.
Additional:
* Proximity Mines can be placed near trees to detect Monkey King.
* Follow up with Blast Off! to destroy the tree, causing Monkey King to take high damage, fall from the tree, and become stunned.

Techies
* Techies deals lots of magical damage with Sticky Bomb, Blast Off! and Proximity Mines that bypasses Terrorblade's high armor and can punish his low max life.
* Sticky Bomb is easy to land on a large clump of Terrorblade illusions and will damage and slow Terrorblade and all of his illusions if he can't quickly move the right one away.
* Reactive Tazer upgraded with Aghanim's Scepter can be used to protect an ally getting attacked by Terrorblade. Further, it disarms all of his illusions even while he has activated Black King Bar, greatly decreasing his damage.
* Blast Off! stuns Terrorblade, preventing him from casting 
Sunder.

Techies
* Thanks to 
Counterspell's magic resistance, Anti-Mage has a good chance of surviving a Blast Off combo.
* Anti-Mage is a natural 
Manta Style carrier, meaning he can dispel the silence from Blast Off and blink away when Techies initiates on him.
Treant Protector
* Anti-Mage relies on blinking and attacking. Overgrowth prevents both.
* Be wary that he will eventually farm up a Manta Style that fully dispels Overgrowth. Good players will wait for your ultimate to use their manta. Perhaps an ally has a silence or similar that would force him to use his manta before your ultimate.
Treant Protector
* Firefly will cut trees with ease, cleaning-up an area that's been enchanted with
Eyes In The Forest, and potentially revealing a Treant under the effects of 
Nature's Guise.
Living Armor.

Techies
* As long as Batrider is under the effect of Firefly, he can safely fly over
Proximity Mines (He does not receive vision over the mines).
