This effect is a jaw-dropper, and is easy to do with a modicum of audience management and some
practice to smooth out the one 'move'. Also, there are zero angle problems. Mainly, though, this is
stronger (i.e., more magical/mystifying) than any other OOTW effects I know. I will definitely be
using this unless I am stuck with an ungimmicked deck, in which case I will use Harry Lorayne's
Impromptu OOTW.
