This is my first guide.
Take your deck of cards. Then shuffle the deck.
Peek at the bottom two cards. Don't let the spectators see. Then think of a card they would make together, I thought the 7 of Diamonds. You could also choose 8 of clubs.
Take out the card the bottom two would make. And say "I picked a random card for you"
Starting at the bottom divide the deck into two different piles one card at a time.
Flip the piles over and say "I made your card out of two cards."
This is a pretty simple trick ill make more soon. Thanks!
