Here's the setup if my memory doesn't let me down: A, K, 6 indifferent cards, KH, X (first 10 cards) A-10 in order of any values (cards 11-20) 12 indifferent cards K (reverse breather) 4, 3, 2 12 indifferent cards K, 2, 3, 4 After they put the cards in the box, you must get a break under the bottom 3 cards and slip cut the top card off with the bottom 3 and place that 4 card packet on top. Now, cut the deck at your crimped K (this puts the K on bottom) to divide the deck into 2 packets. They can now select 4 cards off the top of the 2 packets and the number will always total the thought of number. (They must take at least 1 card from each half, they cannot take all 4 cards from just 1 packet.) To produce the A and 7 to create the #17 from his boxed packet, use the 2 card toss technique to slip out the top and bottom cards of the packet. The number will always be correct because of the A-10 stack. The rest of the way you are home free just doing what you see in the video. If you still need a video tutorial, let me know. 🤜🤛
