I have been using a jumbo invisible deck for years and it plays like Dan Harlen shows in the video.
However the one flaw in the trick I never like was that you have to get the spectator to name the
card before you remove it from the box. But if you also have a jumbo marked deck you can have the
onstage helper select any card from a real deck, all spread out on a table. As they touch the card
you already know it. You turn your head as they pick it up and hold it tight against their body.
The rest is showmanship with the jumbo invisible deck. And it does close a show with a seemingly
real miracle.
