The magician before you start the magical effect of laying on the table an envelope tied with an elastic band inside with a previsone which will be shown later. A deck of cards is handed to a spectator and asked one at a time to serve the papers on the table, face up, deciding when to stop himself. Incredibly, when the envelope is opened, inside you will be the exact same card randomly chosen by the viewer. 
 
A killer effect, from the fertile mind of Steve Shufton. 
 
• A diabolical effect, simple and stunning. 
• Only one paper in an envelope completely normal. 
• The viewer will be used on the table face up cards from a deck which is also normal. 
• You will not have to make any exchange, there is no skill required, but open your prediction will match perfectly with the card chosen by the spectator.
