From publisher blurb:
Polymorph causes the target to change shape, but usually some part of the original target is left intact. That is similar to what polymorph the product line seeks to do. We take existing content and bring together concepts and abilities to create new and interesting stuff for you to use as a player or GM. The dealer is a full 1-20 class that is a gambling, card-throwing maverick of a character. The dealer relies on a luck, skill and daring to perform extraordinary combat tricks with their cards. Also included are rules for combat cards, and a multitude of subclasses for the dealer to be a card cutter, luck manipulating luckmaker or the divination-infused portent reader. Regardless of which flavor of dealer you choose, you will have a class of daring, skill and fun for players and GMs alike.
