An impossible and amazing nested prediction. "Inside" is a card-at-number effect with a mentalism twist that will stun every audience.

You bring out a sealed envelope and ask a participant to freely name a card. A closed card box is then removed from the envelope and given to your volunteer. They open the box and find a deck of cards alongside a prediction folded into quarters. This prediction is shown to say, for example, "Your card will be at number 14". The participant then counts 14 cards and finds their freely-named card.
