A trick with eight cards. Two packets of four cards are put on the table. The first packet is counted and shown to consist of four 3s. The second is counted and shown to consist of four 7s. Then the packets are combined turned face up to show the Ace of Hearts through the Eight of Hearts. So essentially the four 3s and the four 7s have transformed into the Ace through 8 of hearts.
This effect can also be found in Cardwright. You will need to be able to do the Rhythm Count.
