So I have this idea for a trick and was wondering if there was anything similar. So you start off with a playing card and "transform" it into a butterfly, bug, something like that and then you cover it with your hand cupped. After its covered you flatten the cupped hand with the other hand, so to the observer you just killed something. When you remove your hand, you do so while picking up the card you started out with, nothing on the table ie. dead animal. To finish off, you "transform" it again and let the animal go on its merry way
