Black Deck
Black Deck adds one Joker slot and removes one hand every round, changing two listed run resources.
How it works
The source lists +1 Joker slot and -1 hand every round as its effects. The unlock requirement is discovering at least 100 items from the collection. These are the Black Deck effects described in the retrieved passage; it does not specify further starting changes.
