Anti-Mage + Treant Protector

Why this works

Chasing down a split-pushing Anti-Mage gets harder when he has a Treant Protector on his team. The moment a gank begins, Living Armor can arrive from anywhere on the map, providing just enough of a buffer for Anti-Mage to survive the initial burst and Blink away to safety. This global presence allows the carry to farm more aggressively in otherwise dangerous parts of the map, taking towers and applying pressure without needing his support to be physically present. This can sometimes lead to him getting his core items a bit sooner than he normally would.

The main issue is that these two heroes operate on different timelines. Treant Protector wants to group up with the team and force fights using Overgrowth to secure kills and objectives. Anti-Mage, on the other hand, wants to avoid those exact situations for most of the game, preferring to farm in isolation. This often leads to a disconnect where Treant sets up a great fight, but his carry isn't there to contribute damage. The partnership really only comes together in the late game, assuming the team can survive that long playing one man down.
