* 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 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.

* Mortimer Kisses can deal a large amount of damage to Void during Chronosphere, either outright killing him or forcing him out before he can kill any allies caught in his ultimate.

* Living Armor can mitigate a large portion of Spirit Breaker's damage since his attacks are slow.
* Treant Protector can also counter initiate Spirit Breaker with Leech Seed and his bash from Nature's Guise before he manages to escape.
Additional:
* Spirit Breaker's slow attacks cannot harm a hero shielded by Living Armor.

* 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.

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

* 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.

* Another hero heavily based on attacks and no mobility, being an easy prey for Treant strong disarms and motion reduction skills.

* Mortimer Kisses can make quick work of Naga Siren's illusions.
* Scatterblast and Firesnap Cookie's AoE damage are also decent ways to deal with Naga's illusions.

* Living Armor can be used to save a hero from a Relocate gank.

* Mortimer Kisses will quickly destroy Chen's creeps and might waste Hand of God.

* 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.

* Mortimer Kisses can reduce Omniknight's impact in teamfights. Omniknight's Heavenly Grace cannot purge multiple stacks of Mortimer Kisses. The damage is also magical, making Omniknight's ultimate, Guardian Angel, useless.

* 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.

* Heroes with nukes that can jump her: Clockwerk, Snapfire, Spirit Breaker, Techies

* Treant Protector's Living Armor will also negate Tidebringer's damage.

* Heroes reliant on illusions or summons: Broodmother, Chaos Knight, Naga Siren.

* 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

* 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.

* Heroes with summons that are destroyed by a fixed number of attacks: Undying's Tombstone, Gyrocopter's Homing Missile, and Zeus's Nimbus.

* 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.

* Heroes with summons that are destroyed by a fixed number of attacks: Undying's Tombstone, Gyrocopter's Homing Missile, and Zeus's Nimbus.

* Heroes with summons that are destroyed by a fixed number of attacks: Undying's Tombstone, Gyrocopter's Homing Missile, and Zeus's Nimbus.

* 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.

* 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 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.

* Firesnap Cookie can be fed to Snapfire herself or to an ally caught inside Power Cogs.
* A badly placed Power Cog makes it easier for Snapfire to aim Mortimer Kisses on Clockwerk

* Snapfire's AoE abilities in general are effective in clearing Phantom Lancer's illusions.

* 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.
