Sorted Affair by Sean Bogunia

Effect: You display an entire deck of cards, front and back. The cards are completely mixed in a random order. You remove three red cards and three black. The cards are openly mixed, red and black. But when you spread them face up, the colors have separated! The effect is repeated again and again. Each time you alternate the cards more fairly then the next, and still they separate. Finally, the deck is spread face up and the ENTIRE deck is separated into red and black! The special cards do all the work and you get all the credit!
