And I especially like Mr Lucky, a sneeky 10 card poker effect which looks impossible. From the Cellar is another false deal demo, the bottom deal in fact, with the sprectators being entertainingly led up the garden path into believing the magcian has fluffed the deal.
Face Up Centers is a great middle deal demo showing how to deal out aces shuffled to different depths within the deck. The dealer is then found to have the four aces instead. Also, The Cross is another excellent deal with the kings arriving to the dealers hand only to then magically appear in the sucker hand. So far I have seen nothing impromptu to touch it save for Jack Carpenters D.C. Among my gambling favorites are The Sting, an amazing triple duke from a borrowed and shuffled deck. I managed to get hold of a second hand copy of Cardshark recently.
I have to echo Michael Vincents thorough post.
