Moon design, not bicycle playing cards version
Spread a deck of cards face up on the table and ask a spectator to look at any card. No one could possibly know his card because he never touches or names it. You concentrate, then slowly but surely "read his mind" and name the card!
You can repeat it immediately and it will become even more baffling. In fact, even if several people simultaneously look at different cards, you can read each person's mind and name their card correctly every time! John Kennedy's Mind Power Deck is so eerie, so impossible, your audience will be convinced that you possess a sixth sense.
Mind Power Deck can be shown as a normal deck of fifty two cards and even be handled by a spectator without them noticing anything unusual. Yet you'll be able to "read their minds" correctly every time. And there's no system to memorize because the deck does the work for you. You'll absolutely love this trick!
