I brewed this chaos deck with Maelstrom as commander a while back. The first draft version (0.5) was just chaos cards with mass land type destruction. {boil}, {Flashfires}, the whole troupe. I then proceeded to make a somewhat nicer version, still with the cascade enabler. Then C15 gave me {Arjun, the shifting flame}, which was way more suited for the combo aspect, so this build returns to its hatred baseline. Cascade into mass destruction of mostly {U} & {W}, set up locks that make control practically impossible to play, and make everyone ragequit when you proceed to resolve a {warp world} or {thieves' auction} with {hive mind} on the board.
