12 cards, dealt face down.
Face down means face down: you do not get to read your own hand either. Nothing else about the game changes.
- You are dealt 12, all face down.Nobody can see them — not your opponent, and not you. Choosing one is a gamble.
- Play one instead of a move.It turns over and names itself as it resolves: teleport a piece, freeze one, reshape the board.
- Then it is chess again.A played card is public and permanent. Every other rule still holds.
