A triple HITTING Deck Effect! A spectator is asked to think of a time of day. The magician then sets down 12 cards forming a clock. After some joking around, the magi knows what time the spectator selected! The card that corresponds with the chosen time matches a prediction made earlier. AND THE BACKS MATCH! You then show that each card has a different back design.That right Clock-O-Rama is a 'Rainbow Deck as well. 52 different back designs.
