Malygos + Innervate + Living Roots + Living Roots + Moonfire + Moonfire = 7 + 7 + 6 + 6 = 26 damage to the face. With Emperor Thaurissan you might not even need the Innervate. He can also help you to go for a one turn kill, but it's far more reliable to chip away some health and then do your big Malygos turn.

Also, Jungle Moonkin is not a good card for this deck, don't even bother.
