Rocket Racoon and Groot join the list of heroes with fully pre-built and ready-to-play player decks filled with new cards. Whether playing these new heroes or relying on old favorites, players can test their strengths against four brand-new villains: Drang of the Brotherhood of Badoon, the Collector (who appears in two separate scenarios), Nebula, and Ronan the Accuser.

Each of these five scenarios offers a unique challenge that can be played independently or as part of a larger campaign.
