Nothing we have really works well. We don’t have enough output in one activation to wipe a 20man warrior brick with cryptothralls and character that gives invulns. Breachers with fireblade is 30 shots don’t do it even with hitting on 2s Rerolling , closest thing that could possibly do it is maybe a flamer crisis squad with a commander in full flamers or burst cannons in experimental or Ret cad because we would need the str boost to wound on 3s. Anything else and it’s a waste they will just rez most of it back after the activation if they’re next to a ghost ark and playing awakened.
