A very clever take on a well-known principle produces astonishment every time.
The participating spectator becomes the star of the bit, and the reactions make this illusion immensely fun to perform.
Instruction is thorough, and the routine is completely explained.
Other routines suggest themselves.
If you are considering this illusion, or have purchased it, please read below!
There is a hint or recommendation that is given at the beginning of the tutorial, which I ignored.
It took quite a while to get back to square one, so I actually ended up purchasing a second one.
This allowed me to prepare one deck as recommended, which will suffice for almost all audiences.
And now I have a backup, in the event that I would perform before magicians (or frustrate those who like to expose tricks--even though this preparation has nothing to do with the trick itself.)
