Doom + Snapfire

Why this works

Trying to coordinate your biggest spells can feel a little awkward. Doom's entire game plan revolves around his ultimate, which isolates and silences a single key enemy. That hero is effectively out of the fight. Snapfire, on the other hand, wants to unload Mortimer Kisses on a group of enemies that are locked down or moving predictably. The hero that Doom targets is often not the ideal target for Snapfire's ultimate, as they're silenced and trying to disengage. This can force you to choose between focusing fire on the Doomed target or splitting your damage, which makes fights less decisive.

Early on, the lane can feel fine. Snapfire's Firesnap Cookie can help set up for Doom or save him from a gank. The problems show up later. When Doom gets his blink and starts looking for pickoffs, Snapfire doesn't offer the instant, long-range lockdown that helps guarantee a kill before help arrives. In big teamfights, they often feel like they're executing two separate plans instead of one. Doom jumps a backliner while Snapfire tries to find a separate setup for her ultimate on the enemy frontline. It can work, but lacks the clean synergy of a true combo.
