Marvel Champions: The Card Game Core Set required to play.

Each Hero Packs of a cycle will introduce a brand-new hero to play from the Marvel Universe. Each 60 card Hero Pack features a playable hero with a new identity card and a 40 card deck that can be played right out of the pack. Some of the cards in this Hero Pack are specific to the new hero, whereas others can be mixed and matched with the rest of the card pool. As with the heroes in the Core Set, this pack also contains a side quest and rival villain for the featured hero.
