never mind its a setup
This is directly from Ellusionist on the Ultimate Card Through Window page:
[Ellusionist note: please be aware that the majority of the tricks in this DVD involve a setup, sometimes a set up that involves building a gimmick. The DVD is a worthy investment to the magician who can be broadminded while watching, take what he gets, and get value out of the 'Outside the Box' methods delivered in Ultimate Card Through Window.]
It's going to involve somewhat of a set-up...Especially with a trick like this. You can almost always guarentee a set-up, everytime.
