This trick has a couple of problems, mainly from the included video demonstration.
The magician
talks very fast, and he has a spectator that needs to have part of the trick translated into
Spanish. So the back and forth between English and Spanish doesn't help.
The other problem was
at then end, when it was down to two cards, the spectator was choosing the card on the video
viewer's right (magician's left), and the magician changed it to the card on our left (magician's
right).
Then bringing out the pendulum didn't help the viewer, as the magician said he didn't
need it, as he was the pendulum.
