Setup
For this trick, you need to prepare, from a deck of 54 cards (52 + 2 jokers), a special packet, containing 9 clubs, the ace of spades, and 15 red cards. Add one joker in what's left of the deck, and put all 2 parts together, seperated by the second joker. Each individual part can be shuffled.
Predictions : You also need to prepare predictions in advance, on a piece of paper or on your phone :
Spread the deck face-up to show the spectator the deck is completely "normal". Say you don't need the jokers and take them back, but be careful to note where they were !
Split it into 2 packets : the special packet and the other one, which you can recognize with the presence of a joker. Give the special packet to the spectator and ask them to do exactly like you.
Shuffle your deck how you want, and put it on the table. Take approximately half of it and put it next to the other's pile and turn it upside-down. Shuffle it again. Repeat this operation a second time.
Put the 2 parts together, but be sure to flip one of them upside-down !
Next, spread the deck. If you see the ace of spades, turn the deck over. If you see other spades, you're on the right side.
Reveal your first prediction and count the number of face-down cards. Reveal the next one and count the black cards, and say there is only clubs.
When a spectator sees the ace of spades, reveal your final prediction.
