An amazing mentalism effect where the magician, using three special cards that he shows represent three different superheroes shown on both sides of each of the cards, instructs a spectator to arrange them in the order she prefers and to shuffle them, at first with one hand, then using both at the same time.
When finished, she will cover with the palm of her hand at first only one of the cards and then, after the next two-handed shuffle, as many as two out of three cards, with both her hands.
The illusionist, even though his back was turned or blindfolded the whole time, will always be able to divine the superheroes hidden under the spectator's hands, as if he were endowed with X-ray super-vision!
