This is a decent concept, but it really should be a $5-$10 download (especially when compared to the
tremendous value you can get from any of the Dan DaOrtiz ACAAN downloads). The description is quite
a bit hyperbolic and somewhat misleading. This is definitely not a game changer or a must-have, but
it does steer you towards developing a somewhat useful ability with limited applications.
What this is not: a system for memorizing/controlling a shuffled deck or block of cards
quickly. (That was my interpretation from the description.)
What this is (generically): a
system for quickly identifying the position of a selected card and a few effects that apply that
system. The effects are nice, but they are also of the sort that will elicit a smile reaction more
than a "wow!" reaction.
I will practice the technique and use it, but probably more as a
utility than as an effect.
