A collectible card game, or CCG, is a type of card game where players build decks of cards by purchasing randomized booster packs or individual cards, and then use those decks to play against other players. The cards typically feature unique artwork and abilities, and may be based on a wide range of themes such as fantasy, science fiction, sports, or popular culture. Some popular examples of CCGs include Magic: The Gathering, Pokémon Trading Card Game, and Yu-Gi-Oh!.
