Teleport one of your pieces back to a vacant starting square of its own type, once. A rook warps to an empty a1 or h1, a knight to b1 or g1, a pawn to any open square on its second rank, and so on.
You draft Warp Home in Buff mode. Activated: you choose when to use it, and using it is your move for that turn.
As a movement card, it changes how one of your pieces is allowed to move.
