Tiny + Undying

Why this works

Picking these two together often looks better on paper than it feels in-game. The core problem is that they want to win fights in completely different ways. Tiny's goal is to find a key target and delete them instantly with his Avalanche and Toss combo. Undying, however, thrives in long, messy brawls where his Tombstone can spawn a horde of zombies and Decay can wear down the entire enemy team. Tiny's Toss can easily move a key enemy away from the zombies or out of the fight, accidentally saving them from the slow death Undying wants to inflict.

This conflict of interest plays out in mid-game teamfights. A successful lane might create a false sense of security, but when full teams clash, the lack of synergy becomes clear. The Tiny player has to be extremely careful not to throw enemies to safety, while the Undying has to predict where a tossed hero will land to maximize his impact. More often than not, opponents can split their attention, dealing with the Tombstone while kiting the Tiny after his initial burst. The two heroes end up feeling like they are fighting separate battles on the same screen.
