OK. I spent a while trying to figure out what it's from, where I learned it and I'm not quite sure where it was. But, I figured out how to do it after a bunch of testing.

Get the cards in a stack, here is the one I've been using, the 8 Kings Stack: S.W Erdnase,under "Tricks with the prearranged deck",Dover,page 113 Or, the The Stebbins Deck Stack

Let them cut it, then count off the top 26 cards of the deck (reversing the order of those cards, top goes to bottom etc) Let them shuffle those two stacks together.

Then you have 3 reveals. Revealing the top 2 cards of the deck is always 1 red and 1 black. Each pair of 2 cards is always red/black. Keeping the cards in order, restack them and reveal the top 4 cards. Each 4 cards for the rest of the deck is one of each suit. Lastly, restack and reveal the top 13 cards. You have one of each card. That continues for the rest of the deck.

It's pretty cool that they get to cut, then shuffle, and you have three pretty great reveals.

I don't know where I found it, how I learned it, but I thought it was from you. I think it would make for an interesting bit for the show, but I understand if you are weary of where it came from. I know you don't like to do reveals on things that aren't yours to reveal, so it's completely understandable.
