With lots of details:
What I want to know is how many Pokémon are ___ type in card? Like for dark types, how many Pokémon can be dark type in card and have at least one dark type in card? I want to know because I’m organizing my non-hit section of my binder, and I wanted to have a space for every Pokémon. Then I realized that I should do it by type and dex number. But it’s not that simple, because a single Pokémon could have multiple cards of different types.
