Exile the top eight cards of your library. You may put a land card from among them onto the battlefield. Until end of turn, for each nonland card type, you may cast a card of that type from among the exiled cards without paying its mana cost.

Quote from master_of_the_universe »Imagine living the dream and hitting all eight card types in one shot. Now sure, that will likely never happen, but if you can get even four or five off of this, you've pretty much hit the jackpot.
