Beyonder would have been reprinted to reflect a proper inherent ability. Galactus would have been reprinted to give him an 8 Intellect and modify his inherent ability to lower his point total to 24 for tournament deckbuilding.

Legality
The legality of the Marvels OverPower expansion varies. Some groups prefer to play OverPower with the official printed cards and do not consider the Marvels to be legal. Other groups like the new variety of special cards, especially the ones that make characters more useful. The Toronto group of players have decided that the Marvels are legal at tournaments and meetups.
