Although the effect by itself is very strong, you'll most likely get a better reaction if you use it
at the end of an ambitious card routine of some sort. The packaging is very well done. Solid box and
extra material if needed. When constructing the gimmick, really take your time and make sure it's as
close to perfect as you can craft it. The sleight that you need to learn shouldn't be too new to
most magicians, but it'll take a good amount of practice to get it up to performance level. Jon
Allen's dvd teaches a second method that makes the sleight much easier if you're not too comfortable
with the regular method as well, which is a huge plus. All around a great effect that will blow
audiences away.
