I like everything I've got by Rafael including this.
It works identically to what the
trailer looks like, but don't think it's a self-working trick. This is going to take some handling,
so I'd recommend the purchaser have been in card magic long enough to know some of the basics.
The Beginning phase is not difficult, but very clever. The exchange packets phase will take a
bit of work and belief in yourself.
The ending is a give-away of a pretty cool move and
should not be a problem with a little practice.
So... beginner or self-working, no... but
definitely worth the price.
