From the great mind behind the best selling effect "Unwritten", this is Lyndon Jugabolt's new effect "DROP".
The spectator freely chooses any card from the deck, they sign their name on the back of the card and the signed card is lost somewere in the deck. Instantly, the signed card jumps straight to the top of the deck and the spectator can take that card back straight away.
This is very visual and very easy to do. Enjoy performing "DROP".
