I keep a set binder for Team Magma vs Team Aqua, meant to hold every card of that set. This card is one slot in the Team Magma vs Team Aqua set binder. A generation binder holds one card of each species. Poochyena can fill a slot in Generation 3 binder (Hoenn). Themed lists that include this exact card are Trainer's Pokémon and Team Aqua and Team Magma. I still need this card.
