La routine des rois is a mixture of a packet trick and a production of Kings and Aces. You can do it with a normal deck of cards. It is a climax of twists, as you can see from the demo video. You need to know only the Elmsley Count. In any case, I also give you a little tutorial on it. No gaffed cards and no gimmick.
