Magic cards appear in Kingdom Hearts Chain of Memories as a type of playing card which casts magic spells. They can be identified by their blue borders, which they share with summon cards. The seven magic cards in the game represent the spells Sora learned in Kingdom Hearts, and are used in much the same manner; though each spell can be upgraded to more powerful levels as in Kingdom Hearts and Kingdom Hearts II, in this case by stocking multiples of that spell card, they can also be used in various combinations with other magic cards, as well as attack, summon, item, and friend cards to perform completely different spells unavailable in the other games. Many of these new combinations are Kingdom Hearts versions of traditional spells from the Final Fantasy series, such as "Tornado" or "Quake".
Magic cards are only available in Sora's story, though several bosses use their own versions of the cards which depict their faces instead of a specific spell. Sora can also use two special magic cards during the Bumble-Rumble minigame.
