Attack Card

Attack Cards appear in Kingdom Hearts: Chain of Memories and Kingdom Hearts Re:Chain of Memories as a type of playing card which allow Sora and Riku to use their weapons. They can be identified by their red borders. Sixteen of the Attack Cards in the game represent the Keyblades and sword that Sora and Riku used in Kingdom Hearts; the only Keyblades missing are the Jungle King, which was removed when the estate of Edgar Rice Burroughs forbade Disney from reusing Tarzan in the game, and the Keyblade of People's Hearts, which was left out due to storyline issues. The original set of Attack Cards also includes two Keyblades that were introduced in Kingdom Hearts Final Mix ("Diamond Dust" and "One-Winged Angel"). Kingdom Hearts Re:Chain of Memories introduces six additional Attack Cards based on Keyblades that Sora obtained in Kingdom Hearts II, which can be obtained as game completion bonuses. Each Attack card can be used alone to perform normal attacks, but they can also be combined with other Attack Cards, as well as Magic, Summon, Item, and Friend Cards to perform different attacks and spells that are otherwise unavailable. Many of these combinations are reuses or variations of the special attacks from Kingdom Hearts, such as "Strike Raid" or "Ragnarok".

Attack Cards are available in both Sora's Tale and Reverse/Rebirth, but are only used by Sora and Riku, excluding the battle with Zexion in which he can steal Riku's Attack Cards. Sora can also use a special version of the Kingdom Key during the Bumble-Rumble mini-game, and Riku can use a fake version of the Soul Eater during the battle with Zexion.
