Marvel - Who Is The Mightiest? is a 2014 pack that features classic retro comic art versions of Marvel characters. Three alternate versions were released due to certain character license issues, plus a 'Mini Trumps' pack for younger players, packaged inside a card tuckbox. This is the original release, which includes X-Men characters and the Silver Surfer. Due to film/character ownership license rights, all X-Men characters plus the Silver Surfer were removed and replaced by other Marvel characters.
