You are dealer once an orbit. You have one extra deck that is passed to a 3rd party during the orbit, and the deck is stacked. When it's your turn to deal, the deck is switched with your stacked deck; the previous deck is passed back to the 3rd party to be stacked again. The 2 decks rotate in this way. Deck switching seems trivial; passing the deck to another every orbit seems the tricky bit. But hey, I'm no con artist :)
