got to love deception. magic tricks can be extremely simple while complex at the same time, so simple your mind cant really comprehend obviously unless shown. watch in the video at 1:09 look at his left (your right) elbow then look at the same side at 1:14 ITS THE INSIDE OF HIS ELBOW. when they cut away at 1:10 to show the audience they did that so you cant see the switch. watch him on stage... its a little hard to see him flip his arm around
the card trick is the same way every time they switch from the over top view to the view where you can see the 2 girls there are changes made so the process looks like its a "trick"
