This is a lovely, brief piece using 2 cards. It's too brief I think to be it's own effect-and makes sense to then link to a a more substantial routine-a sandwich type being an obvious choice. The problem I saw is that the ad clip shows no usage of the pocket. With 2 cards transforming out in the open, leaving the cards clean. That actually can't happen with this method-so I may only conclude that the inventor ditched 'the sin' off camera. Sin or not, the card that goes into the shirt pocket never goes out of sight, which is critical. The card in the mouth aspect adds interest I think. Going from spot cards to Kings also enhances impact. You will need one gaff to do this trick and it's a standard one. Beyond m.o. presented here, a competent card handler will be able to do this sans pockets. It can actually be done by dropping the pocketed card onto the deck. So, it's a sweet piece of business-but, not worth $7.99.

Great visually with little effort
