Magician by Sam Schwartz and Mamma Mia Magic

Effect

A packet of cards is shown to consist of red backs on one side, blue on the other. The performer says, "These are factory rejects and only one person could do a trick with cards like these." The cards are dealt out and then turned over to reveal that each contains a letter of the alphabet; the letters spell out the word M-A-G-I-C-I-A-N! (or any word of your choice)

Comes complete with an envelope of 10 cards and routine.
