Diminishing Returns is one of the most visual effects ever devised. A spectator names ANY CARD. This card is removed from the deck and tabled. Then impossibly, the ENTIRE DECK is found to have shrunk to MINI SIZE!

The normal sized card which was selected is put back in the middle of the mini sized deck, which is then re-spread.....only this time, the entire deck is back to normal size EXCEPT the spectator's selection, which is now a mini-card!!

As a kicker, the spectator then witnesses the mini-chosen card grow back to full size right before their eyes!

This is visual magic at its best. You get 52 factory made Bicycle cards and a professionally illustrated manuscript.
