I gave it a 5 but thought strongly about dropping it to a 4 for 1 reason. He did everything he could
to make a 15 minute explanation into a 30 minute one. I wish creators would get on with the trick
and explanation and leave out all the "don't do this" and "first I tried this but it didn't work
well".
With that being said I went with the 5 because the actual effect is perfect. Well within
every ones grasp and very well thought out. It is pretty much an any card at number called for that
can be performed impromptu with a borrowed shuffled deck. And it is easy enough for a novice to
perfect.
