Hybrid Format

Hybrid Format is an informal title for the phenomena of Western TCG duelists incorporating Japanese OCG cards into their decks, but still playing by TCG rules. Such duelists usually play by Traditional Format rules by default (as there is no Traditional Format in the OCG, and the Hybrid style of dueling itself is unofficial), and are mostly 'for fun' duelists (duelists who play the game as a social hobby and do not attend tournaments, where they cannot play such a format).
