Brainwave

Always a favorite amongst magicians the Brainwave deck will flabbergast anyone who witnesses it. A deck of cards is shown inside a box and a spectator is asked to merely think of ANY card. The magician takes out the deck, in this case, a red deck. One card is face-up and it is the thought of card! But the real kicker is when the card is turned over, it is the only blue card in the deck!
