I’m not going into all the details here but this “ACAAN” isn’t going to hit 100% of the time and it is NOT the “holy grail of magic”. There are many times when the card the spectator chooses is not going to be at the chosen number, and since this isn’t a normal deck, you will have to put it away and move to another trick. None of the ad copy discusses this and that’s become a huge problem in magic.
