# Erratic Mutation Erratic Mutation is a common from Planar Chaos that appeals primarily to casual players and limited format enthusiasts rather than serious collectors. The card's straightforward instant-speed effect—randomly mutating a creature—makes it a fun, unpredictable inclusion in draft decks but rarely sees constructed play. Collectors view it as a standard common with minimal investment value. The foil variant exists but holds little premium over nonfoil copies due to the card's limited demand. Most interest comes from players completing full Planar Chaos sets or building quirky casual decks around randomness effects. It's the type of card that fills binders without commanding attention.
