Supermind by Henry Evans- Card (M10)

Effect

The magician deals a group of cards to each of seven spectators and ask them to shuffle the cards and think of any of them. Then all cards are put together reassembling the deck. The deck is shuffled and the magician takes it for the first time and starts spreading the cards for himself. After some concentration he names some cards at random and guess the chosen cards, also saying who chose which card.
