There's a trick David Blaine performs on his show, "What is Magic?" where a participant selects a card (I believe in his mind) and then begins naming off the suits that aren't his card. The deck then visually gets smaller, eliminating all the suits that aren't his card. It ends up being a heart that is left and David Blaine then reveals which card he chose. Does anyone know what trick this is or if it's even available?

This was a trick that was supposed to be released but never was. Its called Compression by Dan White and Doug McKenzie

The concept is called the Inflated Deck. It is most recently taught in Greg Wilson's Pyrotechnic Pasteboards.

The rest of the trick you can figure out yourself.
