Juan Tamariz travels the world fooling everyone. Pro magicians. Card experts. Guys who never get fooled.
He's a living legend, and Royalistic is his reputation making 5-card poker trick.

HERE'S WHAT HAPPENS

1. Show 5 indifferent cards, front and back.
2. Do a "secret move" to demonstrate your skills
3. Show that you've instantly swapped the 5 cards out for a ROYAL FLUSH.
4. And the kicker: to hammer home the point that you really switched these cards out right under their noses .. their backs are ALL DIFFERENT, TOO.
