1. If you are new to card magic you will not be disappointed as you will learn one of the best card
sleights in magic, once you have it down you will not stop doing it in or out of this effect trust
me.
2. Oz does an ok job, but i think the presentation needs altering as the effect doesn't
quite make sense at the beginning where the spectator can only peek at the chosen card as if the
magician is withheld from this information he tears a piece off then looks for the other half
straight away, just too fishy! but this is easily fixed with some creativity.
3. Of course
it can be done with a borrowed deck if they have the same deck as YOU! i can't condone this being
stated in the demo.
All credit to the creator of this effect though.
