Just like the other reviewer said, this likely will not be what you think to accomplish this effect.
It's really simple and brilliant (just like alot of Roddy's effects). The only consideration is that
you will have a deck setup prior to performing the effect, if you are wanting to continue to do
other card magic you will either need to steal off some extra items that help you accomplish the
effect or do a deck switch... other then that, its exactly what you see in trailer and as advertised
with a really simple method with no moving/messy parts.
