The 21 card trick from the how to read minds 2 download but instead of cards he uses business cards with images and different pattern kind of like a drawing duplication [...] very very good routine very fun routine once you know the principle you can use it with ABC by Spidey you could use it with MSP you can use it with any deck of picture cards that you want or literally make your own that will work as well.
