Before I bought this deck, I already had several marked or reader decks and I realize now that they were "cool, nice, but not much else ". In cardistry, or in cards in general, a half microscopic piece of information hidden on the back of the cards are good for in reality...nothing. U don't know how much of a tool it can be when the system is practicable and applicable. Just get it. I got 2 more and the Passport (booklet) that has multiple examples of how to do different things. They are concepts that you can build on or just do it word for word like DMC did it. They have a new one now with the alphabet. I'm getting it to. The price is for the technology. This is not easily printed and easily designed. You get what you pay for.
