Unsettle anyone who owns a pack of cards!
You bought a box of vintage things in an estate sale and inside the box you found a creepy old cassette tape. You managed to find a tape player and what you heard was somewhat unsettling causing you to go quickly look at the pack of playing cards you have sitting on your coffee table. It's apparently a recording of some kind of preacher responding to a friend who wrote him a letter, concerned that his daughter was getting into playing cards. As you know, playing cards are sinful, evil, and the Devil's work.
They're not called the Devil's Pasteboards for nothing ...
Listen to a short clip of the nearly three-minute recording here:

It's almost certain that your friend will find in their deck of cards (any deck) what the tape suggests they look for. And when they do, an eerie chill should come over them. Plus, I tip a different way you can use the sneaky knowledge found in the tape to amaze your audiences. A presentation I've used for groups countless times in the past decade or so.
