A incredible deck that at times doesnt get the recognition it deserves, I professionally Pitched Svengali Decks at trade shows for years, some days would easily sell 300 decks. The key I found was as you mention having a combined routine involving as many of the people watching as possible and making it quick and lots of fun do your pitch and sell the decks, I baffled so many people as the deck was shuffled, handled by the spectators, cut the cards, count to the card etc.. and as you mention dont over emphasise the deck is just a normal deck etc. Many times you did not need to show all the deck as 1 card, its a great option and finale but not necessary in your pitch. Honing your routine over tens of thousands of demos you get really good at it and just concentrate on the fun with the large crowds gathering to watch
