Here's a "WILD CARD" effect that makes sense!
Effect:
You openly display six full-color, laminated cards, all identical, say Nine of Diamonds, some of which you place faces down, some faces-up. You then show a seventh card, your business-card, also full-color and laminated. Each of the Nines visibly transform to your business-card, so that you are eventually left with seven full-color laminated business-cards!
