[CINEMENTAL]

This doesn't just fool people. It fools MAGICIANS! The spectator can literally cut to a card, shuffle their packet, and hide the remaining cards without you even looking in their direction. And yet, you will always know what card they were thinking of! That alone is impressive! But then you can do that with multiple people! AND....to top it off, you can end it with an open prediction where you know exactly what card they will deal down to! And NO, this is NOT a marked deck. You don't need to peek at anything, or perform any sleight of hand. TWO THUMBS UP from me!
