Gym Heroes set binder is where a full Gym Heroes set goes. This card fills one slot there. A generation binder holds one card of each species. Graveler can fill a slot in Generation 1 binder (Kanto). Themed lists that include this exact card are Trainer's Pokémon, Kanto Gym Leaders and their Pokémon, and Brock and his Pokémon. I still need this card.
