Actually, I would combine Fed Exed with Angle Zero, to create a much more stronger effect. It would be a smaller routine that could fit into a larger routine.
Opener - Fed Exed box disappearance
Angle Zero - disappear corner
Finish Fed Exed - reveal box with corner of card from Angle Zero inside
At least, that's what I would do. You'll need some good patter to make it really work, but it definitely has potential to be strong. The opener is good, because it's very quick and basically demands attention. Then with the corner disappear, and then the really strong climax of the box reveal with the corner inside. I just thought of this and now I'm going to be using it. Ha ha ha, thanks Sinful, you sparked an idea. (lol)

EDIT: OH SNAP! I thought of a way to perform this for Christmas! Make the disappeared card box appear underneath the Christmas tree, with the corner inside, WRAPPED! Ha ha, I'm definitely going to use that for our Christmas Eve party. Really, thanks a lot Sinful, you sparked a lot of ideas. Peace!
