OCG-only

An OCG-only card is a card which has only been released in the OCG. OCG-only cards are not the same as OCG exclusives; OCG-only cards are all cards that have been released in the OCG but not the TCG, whereas OCG exclusives are cards that have no planned "regular" TCG release (e.g. Booster Pack cards are not OCG exclusives because they have a "regular", anticipated TCG release planned several months after their OCG release, whereas OCG promotional cards are usually OCG exclusives because they do not have a "regular", anticipated TCG release - they may be released in the TCG via Booster Packs, as Shonen Jump Magazine Promotional Cards, in a Gold Series set, or via a number of other possible releases).
