In this expansion/variant to the DC Deck Building, the players are working co-op against specific challenges. Unknown to the table is the one player who has been marked as the Mastermind and who is secretly working against the rest. Once the Mastermind is revealed, it is a race to the finish with the main deck as the timer.
The game play is fun and there's a fun wrinkle to the new main deck cards - all of the cards are incredibly destructive every time they are played. Like a monkey's paw, they give a lot of power or bonuses but burn cards quickly from the main deck. The strategy is to either destroy or negate these cards and keep them out of the hands of the Mastermind.
Combining with regular play: I knocked off 1 star from the total because while it's a really fun variant, you can't/shouldn't incorporate any of the 11 new main deck cards into your regular play. The over-sized hero cards are fine to sort in, and there are no supervillains in this variant.
