Hey, if your a magician IRL, or like to do card tricks, I spent like 40 minutes making a GAFF card for you. Its a tainted ripped from reality smudged card. It looks cool. And well just photocopy it onto a card and viola.
If you are a magician, use a card force to the ace of spades. Then say itll reveal itself, and lookinside there is a unique backed card, you pretend to like shift the card and your done.
