I decided that dawnwalker didn't make the cut since double white mana cost made it so I couldn't play him turn 1. He would be okay in this list though. The hope is to draw an Ageless Mentor or Avirax Familiar and then just beat them down with hugeee creatures. Only using one mystic ascendant because that's all I own. Whichever high drop white legendaries you own will work for the late game.
