Dark Willow
* 
Fortune's End not being disjointable is almost an ensured disable if Dark Willow tries to escape with Shadow Realm. Dispels Cursed Crown and Terrorize.
* 
Fate's Edict negates all her magic damage in case she catches a single hero.
* 
False Promise's strong dispel removes Dark Willow's disables.
Additional:
* Fortune's End can easily dispel 
Cursed Crown before it times out and stuns. He can also save a stunned ally with False Promise.
* Fate's Edict can easily negate 
Bedlam's over-time damage, since the spell provides no form of control. Similarly, he can also negate the magic burst from 
Shadow Realm.
* Fortune's End can dispel the fear effect from 
Terrorize, and it can remove the root from 
Bramble Maze if cast quick enough. Be mindful that Fortune's End only dispels your allies' debuffs on the primary target.
Dark Willow
* 
Magnetic Field lets Arc Warden or allies evade Dark Willow's shadow realm attacks. The duration of the evasion can be extended with the clone.

* Light Strike Array and Dragon Slave allows Lina to destroy trees, countering 
Nature's Guise and Eyes in the Forest.
* Lina has many tools to bypass Living Armor's protection.
Dark Willow
* 
Ancient Seal instantly shuts down Dark Willow's abilities, rendering her defenseless against his high burst damage spells, while she cannot cast spells of her own.
* 
Mystic Flare deals immense burst damage in an area, damaging Dark Willow through Shadow Realm.
Dark Willow
* Nyx Assassin's high burst damage can be the bane of Dark Willow, as her low health makes it difficult to survive long enough to escape through Shadow Realm.
* 
Spiked Carapace can be triggered by walking deliberately into Bramble Maze, leaving Dark Willow stunned and defenseless.
Dark Willow
*

Arcane Curse have the range to hit Dark Willow beyond Bramble Maze.

Dark Willow
*

Treant Protector
* 
Corrosive Haze will reveal Treant Protector even when he is under the effects of Nature's Guise.
Dark Willow
* All of Puck's abilities are area-targeted, and will hit Dark Willow when she uses Shadow Realm.
* 
Illusory Orb allows Puck to bypass Bramble Maze, close the gap and silence Dark Willow with 
Waning Rift.
* 
Phase Shift helps Puck dodge attacks charged by Shadow Realm, and is easily timed against Terrorize's long cast time.
Treant Protector
* Nature's Prophet's Nature's Call can destroy trees that Treant Protecter is hiding in, revealing him.
Dark Willow
* 
Quill Spray's constant AoE damage will hit Dark Willow even in Shadow Realm. Its automatic damage will hurt her if she tries to get close and use Bedlam.
Treant Protector
* 
Doppelganger can dispel Leech Seed. It can also destroy large amounts of trees, counteracting Nature's Guise and Eyes in the Forest.
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.
* Batrider's DoT spells are also good versus Living Armor.
Dark Willow
* Heroes with high burst damage and 
Black King Bar can take down Dark Willow quickly: 
Phantom Assassin, 
Sven, 
Wraith King
Treant Protector
* Invisibility reliant heroes: Heroes with invisibility abilities or those that have invested into invisibility items are hindered by Bounty Hunter's Track. Few examples of such heroes are:
Clinkz, 
Riki, 
Treant Protector, etc.
Treant Protector
* Heroes with the capability of removing or destroying trees greatly hinders the effectiveness of Treant Protector's abilities: 
Batrider, 
Nature's Prophet, 
Lina, 
Enigma, 
Mars
Treant Protector
* Heroes that depend on disrupting fights with ability combos or big ultimate abilities are vulnerable to the long stun of Fiend's Grip:

Medusa, 
Outworld Destroyer, 
Phoenix, 
Puck,

Alchemist, 
Troll Warlord, Wraith King, 
Tiny, Sven.
Dark Willow
* Heroes who can silence will shut down Dark Willow entirely: Death Prophet, 
Silencer, 
Drow Ranger
Dark Willow
* 
Blade Fury dispels most of Dark Willow's abilities, allowing Juggernaut to pass through Bramble Maze and cancel out Cursed Crown before the stun occurs.
* However, Dark Willow can tank 
Omnislash with Shadow Realm. As she is a valid target, but invulnerable to right clicks.
Additional:
* None of Dark Willow's spells pierce Spell Immunity, making Blade Fury a good counter against her. Additionally, it dispels Cursed Crown and Bramble Maze.
* Dark Willow is generally fragile, which results in Omnislash being devastating against her.
* However, if Shadow Realm is activated during Omnislash, then the attack damage is negated (though Omnislash can still jump to other enemies).
Treant Protector
* Heroes with abilities that can save teammates are also effective such as 
Shadow Demon, 
Dazzle, 
Oracle, 
Bane, 
Pugna, 
Tusk, Winter Wyvern, 
Io, Underlord, Treant Protector and 
Keeper of the Light.
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 
Aghanim's Shard upgraded Nature's Guise before he manages to escape.
* 
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.
Dark Willow
* Bramble Maze stops 
Charge of Darkness in its tracks. Its very long duration means it can be used as an obstacle to block off an incoming Spirit Break during teamfights.
* Shadow Realm and Bedlam can be activated when Dark Willow sees Charge of Darkness coming, preventing Spirit Breaker from using 
Nether Strike after the initial stun.
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.
Dark Willow
* 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.
Treant Protector
* Heroes with powerful rooting abilities will disable most of Pangolier's skills, a bonus point if it pierces spell immunity since it will also be able to stop Pangolier during his Rolling Thunder: Treant Protector, 
Meepo, 
Crystal Maiden, 
Dark Willow, Underlord, 
Naga Siren

Dark Willow
* Terrorize, Bedlam and Cursed Crown can damage Muerta through 
Pierce the Veil.
* Even if Muerta has Black King Bar and Pierce the Veil active, Dark Willow can still use Shadow Realm to protect herself against the Pierce the Veil's high damage, as Muerta cannot attack her for it's 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.
Treant Protector
* Treant Protector can usually scout out Magnus in the trees with Eyes in the Forest and disrupt his initiation attempts. He can also counter Magnus' initiation with Overgrowth.
Dark Willow
* Terrorize forces Faceless Void out of 
Chronosphere.
Treant Protector
* Living Armor and Leech Seed can be used to save a hero from a 
Relocate gank.
* Overgrowth can be used to cancel escape attempts with Relocate.
* Once Treant Protector buys Aghanim's Scepter, he will gain access to Eyes in the Forest, that will allow him to enchant a tree which will grant him unobstructed vision in that location, allowing him to keep his allies alerted on Io and his 
Tethered's attempts to gank them, and which can also allow Overgrowth to damage them and root them if they are within a 800 radius of an tree affected by Eyes in the Forest.
Dark Willow
* 
Windrun does not protect Windranger from Cursed Crown's stun or Dark Willow's magical nukes.
* 
Focus Fire cannot target Dark Willow in Shadow Realm and will be interrupted if targeted earlier, wasting the ultimate.
Additional:
* Windrun does not protect Windranger from Cursed Crown stun or Dark Willow's magical nukes.
* Focus Fire cannot target Dark Willow in Shadow Realm and will be interrupted if targeted earlier, wasting the ultimate.
Dark Willow
* Casting Bramble Maze on top of Meepo guarantees a root, as it is nearly impossible to leave the thorns with all of Meepo's clones.
* Terrorize and Cursed Crown offer great disables against the grouped Meepos and can prevent them from using 
Poof to escape.
Dark Willow
* Bramble Maze will very likely catch Marci midair, disabling Marci's chasing/fleeing ability.
* Shadow Realm prevents Marci from bursting Willow down since she relies on physical attacks and unit target spells. With Aghanim's Scepter, Willow can hit Marci while Marci can't hit Willow.
* Bedlam and 
Eul's Scepter of Divinity allows Willow to manfight if Marci initiates with Rebound.
* Terrorize and Cursed Crown combo can waste Marci's ultimate for almost half of its duration.
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.
* Treant Protector's very high damage allowing him to trade hits or contest last hits with Clinkz, while Living Armor can be used to sustain the harass.
* Living Armor protects any of Treant's allies ganked by Clinkz.
* In teamfights, Treant Protector's Overgrowth can disarm Clinkz, preventing him from turning invisible and holding him in place even if he has a Black King Bar.
* Leech Seed slows Clinkz, preventing him from repositioning or fleeing away from danger.
Treant Protector
* Monkey King is one of the few other heroes who can easily traverse through trees, counteracting Treant Protector's ability to hide in trees.
Treant Protector
* Heroes that can maintain vision on Monkey King can see when he uses Tree Dance: Bloodseeker, Treant Protector with Eyes In The Forest, Sniper, 
Weaver
Dark Willow
* Terrorize forces Monkey King out of Wukong's Command.
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
* 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.
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.
Dark Willow
* Primal Beast really suffers against supports he cannot bully in the lane: this includes Dazzle, Shadow Demon and Dark Willow since they can use their respective abilities to stop Primal Beast from dealing burst damage, or make it hard for him to stay in range.
Treant Protector
* Treant Protector's Living Armor will also negate Tidebringer's damage.
Treant Protector
* Heroes with global abilities can give Legion Commander's opponent an edge in Duels from anywhere on the map: Nature's Prophet, Ancient Apparition, Zeus, Invoker, Treant Protector
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.
Dark Willow
* Heroes with high burst damage and Black King Bar can take down Dark Willow quickly: Phantom Assassin, Sven, Wraith King
Treant Protector
* Overgrowth prevents Phantom Assassin from using 
Blink Strike even through her spell immunity.
* Living Armor reduces Phantom Assassin's physical damage whenever she attempts to gank an allied hero.
Treant Protector
* Heroes with invisibility will be detected by Thirst when they have low enough health: 
Bounty Hunter, Templar Assassin, Riki, Clinkz, Weaver, Treant Protector, 
Nyx Assassin.
Dark Willow
* Bramble Maze greatly hinders Bloodseeker's ability to run around in teamfights and pick off dying allies.
* Shadow Realm prevents Bloodseeker from attacking dark Willow, allowing her to safely teleport away.
Treant Protector
* Heroes with the capability of removing or destroying trees greatly hinders the effectiveness of Treant Protector's abilities: Batrider, Nature's Prophet, Lina, Enigma, Mars
Dark Willow
* Heroes with high magical or pure damage will bypass Bulwark: 
Timbersaw, Dark Willow, Enigma, Invoker, Pugna, 
Skywrath Mage, 
Tinker, Zeus, Oracle.
Dark Willow
* 
Counterspell negates Dark Willow's high magic burst damage. Its active blocks Cursed Crown.
* 
Blink allows Anti-Mage to dodge Terrorize during its long cast animation, as well as avoiding the obstacles from Bramble Maze. On the other hand, if Anti-Mage gets caught inside Bramble Maze, he's unable to Blink away.
* Dark Willow's chained magic burst requires a lot of mana, setting her up for damaging 
Mana Voids.
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.
Dark Willow
* 
Ball Lightning allows Storm Spirit to bypass Bramble Maze into the backline, and zip back into battle if he gets hit by Terrorize.
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.
Treant Protector
* 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.
Additional:
* 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.
Dark Willow
* Bramble Maze prevents Timbersaw from Timber Chaining away without getting rooted.
* Cursed Crown can still catch Timbersaw if he Timber Chains away.
* 
Reactive Armor offers little protection against Dark Willow's high magical damage.
Dark Willow
* 
Gust can hit Dark Willow beyond a defensive Bramble Maze, and before she gets close enough to hit Drow Ranger with Bedlam.
* Drow Ranger's long range allows her to hit Dark Willow's team without venturing into her Bramble Maze.
Treant Protector
* Another hero heavily based on attacks and no mobility, being an easy prey for Treant strong disarms and motion reduction skills.
Dark Willow
* Heroes with high burst damage and Black King Bar can take down Dark Willow quickly: Phantom Assassin, Sven, Wraith King
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.
Treant Protector
* With Dual Breath, Liquid Fire and Macropyre Jakiro can quickly remove all
Living Armor from a target.
Overgrowth while staying at a safe distance.
* Ice Path allows Jakiro to prevent Treant Protector from using
Dark Willow
* Jakiro's area of effect abilities can hit Dark Willow even while she is hidden during the
Shadow Realm.
Cursed Crown, Jakiro's Ice Path stun lasts slightly longer then Cursed Crown.
* Waiting about 2 seconds after Dark Willow casts Shadow Realm to cast Ice Path will stun her while her Shadow Realm is at it's maximum damage.
* Jakiro can stun Dark Willow when there is about 1 second left on
