This effect was just so-so for me. If the spectator is too close, they will likely see the gimmick.
If they are too far, they may not really appreciate the effect. This effect really invites close
scrutiny and because of that, they may see the gimmick. However, I did like one of the bonus ideas
that uses the gimmick, but could be better done with a simpler gimmick. It's not a bad trick, just
not so strong in my opinion. I really prefer effects where you can have more fun with people. One
I really like is the cardiologist deck by Tomas Medina. This card effect allows you to really
interract with people and lends itself to a lot of fun. It was ok, but I wouldn't recommend it.
