Supreme Victors set binder is where a full Supreme Victors set goes. This card fills one slot there. A generation binder holds one card of each species. Articuno can fill a slot in Generation 1 binder (Kanto). Themed lists that include this exact card are Mitsuhiro Arita cards. I still need this card.
