Rule of Three | Jon Allen Liam Thanks to his bookFrom the creative mind behind Flexion, Double Back, The Destination Box, The Silent Treatment and more, Jon Allen brings you an incredible new effect: Rule of Three . After naming the QH & AS as the two most popular cards, you ask someone to name a third card. A prediction shows you knew the card they would name! While all the other cards have different numbers on their back up to 52, the QH & AS have #1 and #2 on their back and the named card has #3.
