This trick only requires 11 cards!

Imagine the magician shows a spectator 11 facedown cards. The spectator thinks of any number from 0 to 10. After that, they move that amount of cards they thought of from the top of pack to the bottom of the pack. The magician can figure out what number they thought by picking only 1 card present for that number.
