Path of Heroes
This enchanted deck of cards guarantees victory for its owner in any games of chance by allowing their owner to rearrange the deck as they see fit.
Property: You can attune this deck of cards to yourself by shedding six drops of blood on it during a short rest. Once attuned, whenever you draw or deal a card from the 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 may be attuned at a time.
