Description
Eight of the cards are all the same, for example - the "Jack of Spades." The ninth card is different, let's say it's the Ten of Hearts. You explain that in magic, the "Ten of Hearts" is considered a Wild Card and any card that touches it will also become a "Ten of Hearts." To illustrate your point, you proceed to slowly transform each Jack into a Ten - until all nine cards are shown to be the Ten of Hearts.
