Book Cube Change Set by Syouma & Tsubasa
You scramble a puzzle cube and you announce that it is going to be a magical prediction. You then show a book with dozens of pictures of various mixed cubes that you flip through and ask your audience to say, "Stop" at any point in the book. You then ask them to choose either the right or left illustration.
When you compare the mixed cube to the illustration, the cube's face and the chosen illustration match! The performer then solves the cube instantly, and when you look at the book, all of the cubes in the illustrations have been solved as well!
