The online training video you are led to will give you a bit of training on one use of the cards for
the effect. Unfortunately, it's a fairly lackluster presentation. It's presented very
straightforward, with no demonstration of the effect, just an explanation.
That being
said, the cards do lend themselves to some promising routines if you are creative enough. I don't
think you could do a 15 minute gambling demo using them, but you could do a nice, quick transpo that
a spectator would enjoy. You could also do the included routine as long as you put some enthusiasm
into the presentation.
The cards are (of course) not the least bit examinable afterward,
but if you can do a good switch you might be able to work around that.
