I apologize if this has already been reviewed but I could not find it.
I saw the video and thought it was great.
Magician writes down a prediction and keeps it in plain sight. Has spectators shuffle cards. then spectator deals out 4 ples of cards in any order and stop when they want. Then by process of elimination the spectator elimanates 3 of the piles (completely their choice no force ) and the top card of the remaining pile is the prediction . At no time after handing the cards to the spectator does he touch the cards. I hope this is not a thumb marker. I do not think it is as it seems to be done to quickly. Thanks in advance.

Better to make a mistake here than when performing .
