Doom vs Undying

How this matchup plays

Using Doom on Undying feels like the obvious answer, but it's a trap. The main threat is his Tombstone, and a good Undying player will have it on the ground before Doom can get his ultimate off. Once placed, the zombies keep spawning and attacking regardless of whether Undying himself is silenced. This means you can spend your longest cooldown silencing a hero who is still actively winning the fight for his team. In lane, Undying also bullies Doom relentlessly with Decay, stealing strength and making it impossible for Doom to farm or trade effectively.

As the game progresses, Doom finds himself under-leveled and trying to force a pickoff, while Undying wants to create a chaotic teamfight. The moment Doom initiates, Undying can drop Tombstone and activate Flesh Golem, turning a simple gank into a messy brawl that Doom is not equipped to handle. The swarm of zombies and area damage makes it difficult for Doom to stay on his target or survive after his spell ends. Doom has to catch Undying completely off-guard to have a chance, which is a much harder task than Undying simply staying with his team.
