Senseless Destruction

Each player puts all permanents they control randomly into {x} piles. They then exile one pile, destroy another and return the rest to the battlefield.
"In my dream, the world had suffered a terrible disaster. A black haze shut out the sun, and the darkness was alive with the moans and screams of wounded people. Suddenly, a small light glowed. A candle flickered into life, symbol of hope for millions. A single tiny candle, shining in the ugly dark. I laughed and blew it out."
