About Marvel Overpower Powersurge (Mission Subset)
The Powersurge expansion set included two 7 card mission sets.
These cards are more similar to trading cards, having sharp corners. The mission cards were not used in deck building. Instead, each team chose a 7 card mission at the start of the game. These are then ventured during battles, and a player can win the game by "completing" all of their mission cards.
