Although the demo video fooled me, once I learnt this trick, I know I am not going to perform it. I
don't mind a non-sure-fire effect, but this trick requires a quite complicated set up, which does
not it, especially when you fail to predict the card correctly in the effect. There're lots of other
card prediction routines that look better than this one and are more practical than this one. To
conclude, I don't recommended this trick.
