You display a group of cards each with a target printed on its face.  There is also a hole going through each card.  Unfortunately, your aim was way off and the holes are nowhere near the target.  With one exception... one card has a perfect bullseye! 

With a magical flair, you begin to move each hole so that it is now located right in the center of the target!  You repeat the process with each and every card, until all the holes are perfect buls-eyes!  Who needs target practice, when you are a magician?!  Custom cards on Bicycle Card Stock!  A visually striking effect to behold... and perform!
