A card with a status of not yet released in the TCG or OCG refers to a card that doesn't yet exist in the format in question, but has a confirmed debut. It is sometimes possible to own a card before it is officially released (like from a Sneak Preview Event or an English Duel Terminal). However, it is not considered a legal card until the release date. This status is by definition temporary, so the lists below are constantly changing, and may at times be empty.
