Mosaico De Cartas

EFFECT: A card is freely chosen and, without being seen, is left face down on the table. A paper is then shown that has 16 cards printed on it; it is folded several times and, with a single scissor cut, the black cards are separated into one pile and the red cards into another. However, among the black cards, a red one is found, which turns out to be the one that is face down on the table.
