This effect is technically easy to do. If you can do an overhand shuffle and overhand shuffle
control (OSC), you can do this trick. In fact, Dani doesn't actually use a traditional (OSC) so you
don't even really need that. There are no real sleights required.
It does however require
some good audience management and the only way to get good at this effect is to do it for live
audiences. So you will have to learn the sequence, and then just go out and do it. Note that you
MUST have at least 3 spectators to get it to the level of miracle he shows.
This effect
performs exactly as he shows in the demo. It doesn't seem possible that the last spectator shuffles
the deck, selects a card, and it turns out that it is in fact his own card. But that is precisely
what happens. This is a real miracle. I think it is one of the best in this series.
