A freely selected and signed card is returned to the deck. The magician puts two rubber bands around the deck, one along its length and one across. The magician hold the deck so the bottom card is visible. The visible card suddenly changes to the chosen and signed card without any cover.
A totally visual change!
The deck of cards is not included. Can be done as a trick on its own, or used as a final grand climax to your favorite ambitious card routine.
