A card is selected, returned to the deck and the deck is shuffled.
The magician claims he will find the card, You are so confident that if you fail you will give them a chance to win 50,000 dollars!!
You fail to find their card. From your pocket, you remove a lottery scratch-off card. “Here is your chance to win, 50,000. I never said it was a good chance”.
The scratch card is placed onto the deck, Faster than the blink of an eye it changes into their selected card.
Custom-made gimmick, it’s all magnetic locking, you can casually toss the card into the air. Then hand it back to them.
