As for tournament legality, SPM cards are Standard-legal, SPE cards are only Eternal-legal, and the rest are legal in whatever they've also been printed in.

Magic Arena will be getting legally-distinct versions of these cards, since Marvel didn't want to extend the license to digital play. Only three have been revealed so far.
