Wow! That was actually very clever. I was watching after the spades wondering where the cards were, because I saw your hand completely as opposed to having them palmed! It never occurred to me that you were ditching them as you dealt. Amazingly clean too!
Could I make a suggestion though? If you were to deal out the last 4 cards (the aces) on to the top of the pile, I think it would be a lot cleaner. It would separate the deal from the reveal even more. Besides that, there isn't much more I can add. It's been one of my favorite moves to watch ever since I first ran across it in a TEDx Talk. I've been wanting to buy the Snap Deal booklet ever since, though it's been sold out for a while. I've been thinking of learning it from Takumi Takahashi's "A Study on Lennart Green", though I've been practicing other stuff for a while. Where did you learn it?
Mad props!
