Oh here's a funny story, you can try it out sometime. I was performing for what seemed like a really smart ass guy. He would try to call me out on all of my tricks like my coin and rubber band tricks. So i decided to mess with him a little bit. After doing a few card tricks, i knew he would want to see the deck. So i handed it to him and said "No, but it's really simple. I do all this with a trick deck. Here take a look, see how they're not normal. They REALLY look real dont they? But they're actually all the same card. Convincing isnt it?" In reality, it was a regular deck but he fiddled with the deck for like 10 minutes trying to find some kind of gimmick. It was pretty funny.
