The plan of the of the deck is to mill some units with
Fallen Oni then bring them back with
Argenport Ringmaster. There's
Memory Dredger,
Devour and
Dark Wisp for card advantage and the rest of the deck is removal to live long enough to make it to showtime. I'm considering adding
Dreamsnatcher to help against aggro but I'm not sure what to cut for it.
