Cards with the “G” regulation mark will no longer be legal for play in the 2026 Standard format. Cards with “H,” “I,” and “J” regulation marks will be legal to use (as will any future regulation marks that may be released). A card’s legality status is not based on which expansion it’s from. Even if a card is from a recently released expansion, players will need to refer to the regulation mark on the bottom of the card to see whether that card is legal for play. New cards still must follow the appropriate waiting period to become tournament legal, which is typically two weeks after their release.
