Bat Credit Card

The Bat Credit Card is an artifact in the Tiradesverse that allows any character possessing it to buy anything they want.  It has no known expiration date.  It was forged in the bowels of Tartarus by Akiva Goldsman and is one of the most stupidly offensive things ever put into cinema.  Legends say that if Nic Cage's Career ever came into possession of it, the entire multiverse would be put in grave danger.
