In the One Piece Trading Card Game (TCG), the Standard format is the primary and most widely played format, where players construct decks using only officially released and legal cards as determined by Bandai. Decks must follow a specific construction rule: exactly 50 cards in the main deck and one Leader card, with no more than four copies of a card with the same card number allowed. The Standard format includes only cards from booster packs, starter decks, and promotional sets that are currently legal, and it excludes certain banned or restricted cards as listed in the official rules. This format emphasizes balanced competition and strategic variety, reflecting the evolving metagame of the One Piece TCG.
