Shadow Fiend + Weaver

Why this works

Stacking two fragile damage cores looks like it creates a ton of kill potential, but the reality is much different. Both Shadow Fiend and Weaver need another hero to create openings for them; neither one provides the lockdown the other requires to land their damage safely. Weaver is elusive but offers no stuns, and Shadow Fiend's entire kit is about hitting targets that are already controlled. While their armor reduction abilities can stack, it rarely matters if you can’t hold anyone down long enough to right-click them. They end up competing for the same role in a fight without enabling each other.

This lineup puts immense pressure on the other three heroes to provide all the team's control and frontline. Fights often go poorly because the enemy can simply walk at Shadow Fiend, forcing him out or killing him before he can have an impact. Weaver is then left alone, using Time Lapse to survive rather than to reset after a kill. Without a strong initiator to set the tempo, both cores struggle to find safe farm and are easily picked off. The game plan feels disjointed, with two heroes wanting to be the star of a fight that never gets a proper start.
