An envelope containing a prediction is presented to the spectator and remains in plain sight until the end. The spectator then generates a random number. Next, use that number to try to guess a card from the deck. The card chosen by the spectator is then returned to the deck, and the magician reveals their prediction inside the envelope. However, the prediction seems to be completely wrong, and the situation seems to get worse and worse. Until, in the end, the magician reveals the hidden meaning of the prediction and manages to guess the location of the spectator's card. Furthermore, the magician manages to prove, in the end, that they knew which card the spectator had from the beginning and, finally, reveals that the rest of the deck is completely blank.
Bonus effect: Jacob will also teach an improvised version of the trick, which uses a common, borrowed, and shuffled deck. Sounds too good to be true? Believe it, it's not. Both effects taught in this download require little manual skill and are practically automatic.
Note: You will need to purchase your own blank decks to be able to perform the trick version!
