Property: You can attune this deck of cards to yourself by shedding six drops of blood on it during a short rest. From that point forward, whenever you draw or deal a card from this deck, it is of a suit and value of your choice. Anyone else who interacts with the deck finds it to be a normal deck of whatever game it is designed for. Only one creature can be attuned to the deck at a time.
