Brainwave Deck - Royal version
Magician asks a spectator to think of any card and call it out.
A deck of cards is removed from its case and spread face down until one face up card is seen to be the spectator's chosen card!
But wait… the card is turned over to reveal it has a different colored back! Magician explains that he inserted this card in the deck before his performance and controlled the spectator to think of this one card!
Deck and instructions included.
