Lifestealer + Undying

Why this works

Picking a carry to pair with Undying's lane dominance can be tricky, but Lifestealer is a natural fit. Undying excels at creating a chaotic brawl with Tombstone and Decay, slowing enemies and draining their health pool. This creates the ideal scenario for Lifestealer to use Rage and simply run at the weakened, slowed targets without fear of being disabled. While opponents are distracted by zombies, Lifestealer gets free rein to attack. The strength drain from Decay also makes his job easier, turning tanky heroes into much softer targets.

This duo wants to group up and force objectives as soon as possible. Dropping a Tombstone on an enemy tower forces a difficult choice: deal with the zombies and the tanky Undying, or deal with a spell-immune Lifestealer tearing through the backline. To win, opponents have to find a way to clear the Tombstone zombies from a safe distance or have enough mobility to disengage from the fight entirely. If they try to stand their ground and fight head-on, they'll usually be overwhelmed by the combined pressure.
