A card is chosen and we take out of an envelope (the Joker) we say that it is valid for all the cards and then the magician turns it over it is blank and with a candle he makes the card that the spectator took appear. The magician takes out of his wallet a prediction the King of Diamonds, the sample says that now the spectator draws a card and that it will coincide with the prediction, the spectator draws the 5 of hearts.
It does not fit! but the magician borrows a lighter and the 5 of hearts appears on the white back. These are some of the things that can be done. The limit is the imagination, you will find in the videos the complete presentation, a video to make our secret and finally the explanation of the three routines, all the videos are recorded in Spanish, but they are subtitled in English and are easy to understand.
