I keep a set binder for Shining Legends, meant to hold every card of that set. This card is one slot in the Shining Legends set binder. A generation binder holds one card of each species. Mewtwo can fill a slot in Generation 1 binder (Kanto). Themed lists that include this exact card are Mew and Mewtwo. I still need this card.
