Like the Ghost Deck you know from Balatro, only it won't cause Spectral cards to appear in the shop. 

This official deck of cards, based on LocalThunk’s original in-game designs, includes 52 standard playing cards as well as four Jokers: Seance, Mr. Bones, Sixth Sense, and Castle. It's printed by the United States Playing Card Company and packed in a tuck box accented with silver foil.
