Flash deck switch is great!
Video provides different ways in using this gimmick which is great
because it opens up many possibilities.
Only downside is that it is a gimmick that at first is
hard to manipulate. It takes time to master. Difficulty is raised when using a full 52 card deck.
But, as they all say: Practice makes perfect. Time has to be put into this to master not only the
technique but also misdirection.
