I took a list for a spin last night, went 1-2. Mostly won round 1 due to bad hands from Reanimator Depths, then lost to 4c Control and DnT 0-2. DnT I beat in an extra game, but effectively lost each round due to not being able to wipe out Vials or Shamans. Boards of like, landing a Crucible just after a Shaman hit, then more shamans and a Leovold joining the party, not being able to cleanly get through Strix to get walkers, or being locked out by Sanctum Prelate on 2. I think 2x Ratchet Bombs are definitely necessary. I liked the Tombstalkers definitely, and might consider the other Delve demon as extra removal.
I did bring in a Culling Scales that would have cleaned up the 4C game and had it wipe out DnT's board to seal that game.
