Factory Seconds by Satish B

This is a fun card trick with multiple climaxes. It starts off as a 4-Ace production trick, then it goes wrong as 4 random cards are produced instead of the 4 Aces. Next, these random cards are shown to be predicted on the magician's Facebook page. Not to be outdone, the magician also produces the mates of the 4 random cards. At last, the magician produces the 4 Aces. Of course, the best part is that the deck is face-down almost the entire time and it is handled by the spectator.
