Shadow Moment of Exile Deck
This deck is shooting for the late game when Moment of Creation brings down 2 enormous golems and a 7-cost unit to boot.
It runs an enormous removal suite to keep the board clear but watch you don't get overrun by tokens (see Plague) or have a New Tomorrow/Scourge dropped on you (race them/ shepherd those Sabotages). Sleepless Nights can help you refill an empty hand and throw you a potential Scion or Marisen as well.
Edit: Swapped out Vara Choice and 2 Seek Powers for 4 Trail Stories.
