The cards cannot be examined before the effect due to the use of an obvious gimmicked card. They can
be "shown" before, but not examined. Afterwards you have to come up with your own approach for
dumping and replacing the gimmicked card with an ungimmicked one before the cards can be examined.
I gave this a 3 and not a 2 only because it got me thinking about how to do the effect
without using a gimmicked card at all. My resulting reworked approach allows you to end clean with
everything able to be examined before and after.
