I hope this deck works, because it should be fun. So you want to play your huge minions as fast as possible.
First way, draw Nozdormu the Timeless with Call to Adventure, and get to 10 mana crystal. Or defend yourself until you can play Duel! or Commencement. Most of the minion played here have reborn, a strong deathrattle or a end of turn ability. If you can stick one of them to the born make a copy with Gift of Luminance .
