Premium Cards
Premium Cards are cards in Kingdom Hearts: Chain of Memories that can be equipped at lower Card Point(CP) cost than regular cards, but do not reload after use. They are distinguished by their shining surface and yellow numbers.
Premium cards can be either found in battle or bought from the Moogle shop at random chance. Alternately, a card may be changed from normal to premium. This can be accomplished in a room synthesized with a Premium Room map card. Upon defeat of an enemy, a yellow P symbol may appear. If it is picked up, at the end up the battle, a roulette will appear of all the attack and magic cards that are in the currently equipped deck. The card selected from the roulette is turned into a premium card.
