Legendary: A Marvel Deck Building Game – Guardians of the GalaxyExpansion

From BoardGameGeek:

Legendary: Guardians of the Galaxy, an expansion for Legendary: A Marvel Deck Building Game, adds five new heroes to the game for players to recruit. Using these heroes, players can create their own powerful combos on the fly, combining their heroes' awesome abilities to take down nasty Marvel Masterminds like the Kree Supreme Intelligence! Note, this is not a standalone product. A core Set (including Villains) is required for game play.
