I keep a set binder for HeartGold & SoulSilver, meant to hold every card of that set. This card is one slot in the HeartGold & SoulSilver set binder. A generation binder holds one card of each species. Wigglytuff can fill a slot in Generation 1 binder (Kanto). Themed lists that include this exact card are Igglybuff, Jigglypuff, and Wigglytuff and Atsuko Nishida cards, early series. I still need this card.
