I am a bit concerned that the working of this trick might appear at least a little suspicious to
some onlookers. I will say that if the pace of the performance is fast without hesitation even the
obvious part of the "gimmick" won't nescessarily give away how it is done. it is a good thing that
after the performance the deck (which is indeed a regular deck of normal cards) can be freely
inspected. But it should be noted that the deck can't be borrowed or inspected before performing the
trick.
