Aotoz, God of Splintered Seas

As long as your devotion to blue and green is less
than 7, Aotoz isn't a creature.
Whenever Aotoz would die, instead lose 2 life,
shuffle Aotoz back into your library and create
three blue 6/6 serpent creature tokens.
Whenever you tap a land for mana, add an
additonal mana to your mana pool of the same
type that land produced.
