Pokémon enthusiast's collection

CARDS

Think of what many fans trade or store in binders, often featuring creatures like Pikachu or Charizard. These paper collectibles are a staple beyond just the games.

A Pokémon enthusiast often collects trading cards featuring their favorite creatures, so "collection" hints at something they gather. The word "cards" fits perfectly because Pokémon trading cards are a core part of the franchise’s fan culture. The clue plays on the idea of a hobbyist’s prized items, making "CARDS" the straightforward answer.
