https://en.wikipedia.org/wiki/Collectible_card_game

"A collectible card game (CCG), also called a trading card game (TCG) or customizable card game, is a kind of card game that first emerged in 1993 and consists of specially designed sets of playing cards. Terms such as "collectible" and "trading" are used interchangeably because of copyrights and marketing strategies of game companies. The rudimentary definition requires the game to resemble trading cards in shape and function, be mass-produced for trading or collectibility, and it must have rules for strategic game play."
