This is a good idea and solves the problem of carrying around a card box for one trick or piece of a
trick. The only downside is that the switch (if one is not careful) looks like a switch. By
spending some time in mirror work and making sure not to rush the throw down of the card, I believe
this could become a thing of beauty. It will take some time, practice, and thinking; but isn't that
what we all want?
