This is a gaffed deck like you have never seen before. It is produced using a stock that is very similar what the USPC uses and the faces are very similar. All the cards are gaffed in different ways except for 20 which are the ones that have backs. This is important since you can switch those 20 cards with any back design you like that has matching faces. So even though these come in an Empire back design you can easily convert it to your favorite Bicycle deck.
Along with the special deck you also get a link to an instructional video that teaches you two simple triumph routines that do not require any sleight-of-hand.
Basically, the effect is of the deck being cut face up and face down until it looks like a face-up and face-down mess. You can then immediately spread the cards to show that all the cards are now face up. You can then immediately re-spread the cards to show that they are now in new deck order. The two versions taught are with and without a selected card.
By using some ingenuity and adding some sleight-of-hand to this deck you can probably create a masterpiece of card control.
