Death Prophet + Night Stalker

Why this works

Picking these two heroes together forces a choice between two very different game plans. Night Stalker's entire game revolves around using Dark Ascension and the night cycle to isolate and kill single heroes. He wants to hunt. Death Prophet, on the other hand, wants to group with her team, press Exorcism, and run at towers as a unit. While their silences can stack up, their fundamental objectives often clash. Night Stalker excels at creating chaos and skirmishes, while Death Prophet prefers a more organized, front-to-back siege where she can sustain through a fight.

This tension plays out across the mid-game. For this duo to work, one hero's plan has to directly enable the other's. For example, a successful gank from Night Stalker has to immediately convert into an objective for Death Prophet's team. More often, you see Night Stalker off on his own hunt while Death Prophet is trying to rally for a push, leaving her without a key initiator. Or, if the team commits to a five-man push, Night Stalker's potential as a lone predator is wasted as he's forced into a more generic frontline role. They aren't actively working against each other, but they don't naturally help each other win, either.
