There was a routine that I loved. It used three cards, two of them were the same (the joker's for example) and one of them was different (a queen, for example) and placed in the middle. The routine consists in having the espectator holding the "three cards" and the middle card would be pulled and placed between the other two cards, when it was pulled again the queen vanishes. The same thing would be done again but this time face up, and when the card was pulled again, it's back changed to another color. Can anyone help me?
