The Spectator chooses any card from the deck. The magician rips off the corner of that card. One hand wave, and the corner changes color. The magician throws the corner on to the card, the card is restored and the whole card changes color. And that’s not the end. The magician places the card on the deck and the entire deck changes color. Four effects in one trick. (Supplies may have to be purchased in order to perform this effect.)
