Hey. Recently got the game, so I've only played a few matches. The internet consensus seems to be that The Reavers are the weakest faction, however as new expansions and new cards keep coming out, it could help them if GW prints cards that strenghthen a existing strategy or enables a new one. So if we may indulge in some wishful thinking: What are some made-up cards that would help the Reavers?
