You show a deck of cards in your hand.
You ask a spectator to name any card in the deck (Free choice).
You show them that on the deck there is a small STICKER with a note….. saying a number (20).
You tell them this note
A spectator freely chooses one of two decks, red or blue (not a force). The other deck is set aside. From the chosen deck the spectator reverses any card sight unseen. The deck that was placed aside is now spread on the table by the spectator.
