I've been doing magic for over 17 years, with a heavy focus on card stuff.
Daryl Martinez,
Brian Tudor, Juan Tamariz, Dan and Dave, Apollo Robbins
and David Blaine were some of card
experts that I studied. So for what its worth,
my opinion of this slight is this.. It looks
killer in front of a mirror at
precisely the right angle. If someone is either left or right of
you, forget it!
AND, if its quiet, you can HEAR the shift!
There are WAY better ways to
control a card to the top than the selenium
shift. But like I said, Its looks nice from the
perfect angle.
