Well that explains it. I watched the video and can see how it is done as a packet trick.
I learned the Vernon version and after some considerable practice got it right.
I was deployed in Al Udied at the time and my friend and I were doing a magic session once a week.
You should have seen the cards I was practicing with, I wore the color right off the backs on several sets before I was done.
I have also spent much time doing it because it is fun, visual and easy. But it is pretty well one sleight, and if you are sufficient at the sleight (Elmsley count) 2 easy block push offs, and 1 card displacement, it is a pretty easy effect. I think that effect is a big factor in which made me so efficient and the ghost count. But yes, I have have practiced this effect a considerable amount as well, but more for the ease and fun of it. It can be quite a strong effect if performed properly but very lame and boring if performed incorrectly. Like every effect I guess but this one is particular since it is not on my list of an astounding effect even to the lay.
