Bammo Card Walloper 2.0 by Bob Farmer

A deck is removed from its case, casually shuffled, and shown to be in no particular order. Half the deck is turned face up and half is turned face down and the two halves are mixed together. Spread face up on the table, the deck is seen to be a chaotic mess of face-up and face-down cards, suits, and valuse. The deck is squared, then immediately re-spread: now, impossibly, not only are all the cards face-up, but the entire deck is in order, by value and suit!
