Inspired by kamikazi1000's Double-Deck Wins (see http://www.mtgvault.com/ViewDeck.aspx?DeckID=268022) I thought I'd put this deck up. The idea is that for your first game you have a particular type of deck, then for the second game, sideboard for dramatic changes. The original deck is focussed on pumping out strong tokens. After sideboarding out the token buffing enchantments, Elspeth Tirel, Martial Coup and Conqueror's Pledge, the deck uses Mass Polymorph to mill the opponent with Halimar Excavator (4 x Excavator each triggering 4 times with 4 allies on the field = 64 cards into opponents graveyard) and Pact of Negation to ensure polymorph resolves. Hagra Diabolist is another option for a mass ally effect. I wonder if this could work...
