I really like this effect. The first sleight isn't hard and after a few minutes you'll have it. The
last sleight where the cards comes to the top is your angle problem if you can call it one, you just
can't be surrounded. I've played with it enough that if you wanted to erase the last move you could
do a double in the beginning so the specs see the card move up and the last time a traditional push
the card in and now it's on the top. Actually working on pushing it in and pulling top card out to
create same illusion. Well worth it and not a huge amount of time, a nice close to ambitious card
for sure.
