I keep a set binder for Diamond & Pearl, meant to hold every card of that set. This card is one slot in the Diamond & Pearl set binder. A generation binder holds one card of each species. Mantyke can fill a slot in Generation 4 binder (Sinnoh). Themed lists that include this exact card are Baby Pokémon. I still need this card.
