A visiting magician performed this for me. I had not ever seen it before.
I shuffled the cards and he took the deck back, showed the cards thoroughly shuffled. He then quickly cut it into 10 piles. The first packet had just one card! The second packet contained two cards, the third three cards and so on, all the way through to the last packet containing exactly 10 cards!
I was mildly impressed but that was just the start.
The top card of each packet is then turned over (remember I shuffled the deck!), and the first card is the Ace of Spades. The card on top of the second packet is the Two of Spades, on top of the third packet is the Three of Spades and so on all the way through the rest of the packets! My jaw began to drop.
The Ace through Ten of Spades are then set aside and the deck is reassembled.
I was more impressed.
The Jack, the Queen and King of Spades were produced with a flourish!
I was reeling from this when he cut the deck again into three piles and each contained thirteen cards of the remaining suits, in numerical order!
I was blown away. Knocked me off my barstool.
Yes the deck is gimmicked ...to the max... but I have been using this as an encore trick at my private parties and it plays extremely well. It is the perfect "Oh, can you do one more!?" trick!
Comes complete with the necessary deck of Bicycle cards and detailed instructions.
