A chooser of the slain rides beside your army: for your opponent's next 3 turns, any knight, bishop, or rook of yours they capture is carried home to your pocket instead of being lost for good. Drop it back onto an empty square on a later turn.

As a pieces card, it summons, revives, promotes, or converts a piece.
“Not this one. This one still has work to do.”
