Doom + Tiny

Why this works

Trying to eliminate a key enemy often goes wrong because these heroes work against each other's goals. Doom's entire game plan revolves around his ultimate, which isolates one opponent and makes them vulnerable. He needs that target to be focused down. Tiny, however, wants to use Avalanche and Toss for area burst damage and repositioning. A stray Toss can easily move the Doomed target to safety or pull them out of Scorched Earth's radius, completely negating Doom's setup. Their primary tools for starting fights are fundamentally at odds, with one wanting to pin a target down and the other wanting to throw enemies around.

This lack of coordination creates problems throughout the mid-game. After the laning stage, both heroes look to make plays, but their attempts to gank together can feel clumsy and ineffective. One hero's initiation often ruins the other's. In larger teamfights, the Doom player has to worry about Tiny accidentally saving his target. To succeed, this duo requires an unnatural level of communication to coordinate who Tiny can and cannot Toss. Most opponents will exploit this by clumping together, making it impossible for Doom to find a clean ultimate without Tiny disrupting the whole fight.
