This packet trick is a wonderful opener: imagine "All the Non-Conformists" on steroids and then having a precocious lovechild with "Dr. Daley's Last Trick." Mentalism, transformations, multiplications, vanishes, and transpositions all meet in one sweet (and totally examinable) little package. This pdf also comes with the cards so you can perform the effect as written. And buy two and use the second one as a gift for that person you really love!
