Roaring Skies set binder is where a full Roaring Skies set goes. This card fills one slot there. A generation binder holds one card of each species. Taillow can fill a slot in Generation 3 binder (Hoenn). Themed lists that include this exact card are Atsuko Nishida cards, later series. I still need this card.
