So I first thought of the idea of a cut and restored deck of cards around 2002, I believe. I have always loved stage illusions and liked the idea of doing similar effects on a smaller scale. I have also created two methods for a zig-zag deck.
Playing with a deck in my hand, I instantly knew what a great method would be, and I used a blue Waddington card case to make a physical mock-up. I stuck two rope magnets on the side as the catch.
The effect worked well, but of course, the thin card case was too flimsy. Sometime after, I made a prototype out of balsa wood. I loved working with balsa back then. It worked great, and I made a video of it too!
