That shrinking deck effect is more commonly known as the Inflated Deck concept, originated by Lin Searles. It was first published in the 1930's and later re-popularized by David Harkey. Gregory Wilson also used it and taught it in Pyrotechnic Pasteboards. It's a very, very simple and versatile concept that can be used for vanishing deck effects, Ambitious Card, etc. Recently, it's primarily been used as a throwaway sight gag, but it appears as though it's been re-modified to stand on its own as a solid effect again. I was pretty impressed seeing it revived on television.
Hope this helps,
