Like battle cards, a map card has a value ranging from 0 through 9, with the exception of Keycards, which are unique. Map cards are only acquired at the end of a standard combat encounter, provided no enemy card drops, and the limit of 99 cards has not yet been reached (Keycards excluded).
They are used by Sora and Riku to create rooms within the floor-worlds of Castle Oblivion through room synthesis. Map cards are cards in Chain of Memories and Re:Chain of Memories.
