Swap Cards allow handlers to, when one of their characters is rolled, kill another of their characters instead. Each handler gets one Swap Card per Mini or AU. Swap Cards have been in play since the beginning of Mini. Thus far, the only time Swap Cards have not been used has been SOTF: Evolution, because each handler was only allowed one character.

Together with Hero Cards and Roll Nulls, Swap Cards are one of the only ways to save a rolled character.
