The original tarot decks used by Amberites had some or all of their major arcana cards replaced (or possibly augmented) with images of the royal family, and of at least one location, Castle Amber. These original decks were created by Dworkin, and a deck was given to each family member after they first walked the Pattern. Physically, these cards are cool to the touch. The decks may be used like normal tarots for divination, as Corwin does shortly after meeting one of his brothers.
