Are we allowed to link to other fora?
I hope we are because you can read more about the Juice at the

Tbh it looks like more of a gamblers tool and you
must use Bees or similar back design. If you just want marks for magic/mentalism it's going to be much simpler to go the Ted Leslie route or use one of the nice pre-printed decks that I reviewed a while ago. Or, depending on what you want to do, there's the to-all intents-and-purposes-totally-indetectable Sense of Touch by Ian Rowland, although this has limitations and the book is now oop (and I've just sold mine).
