One of the best selling decks in magic.
The Spectator thinks of any card and tells the magician.
The Magician removes a deck of cards, lets say blue back, spreads the deck face down and the only card face up in the deck is the spectators’ card! Not only is it face up, but it is red back!
A companion to the “Invisible Deck” the debate is ongoing as to which is more powerful… get both and save yourself the headaches!
