First off, this IS a great effect and haffless version of DaOrtiz' triple i intuition. This is
clever and yea the audience won't be able to backtrack it.
But, to novices or magicians
that are not used to DaOrtiz' work and style... don't read the advertising and see "hands off" and
"borrowed shuffled deck" and take that literally. There is a stack, A SMALL stack and unless you're
proficient at culling, you would have to set this up BEFORE you perform. So keep in mind you'll
definitely have to practice some culling if you truly want to do this with someone elses deck. And
as far as hands off goes... there is some things you have to do before that becomes accurate, so
just be aware this effect will take some practice and it should, because it really deserves it.
