About this card
Mewtwo throws both arms out past the edges of the window, tail hooked up behind it, head dropped so the face stays in shadow. Masago is credited eight times in Expedition's numbering but painted four pictures for it, because each of his holos was reprinted without foil further down the list. The other three are Blastoise, Skarmory and Tyranitar, all of them inside the set's first thirty-two numbers.
