Do you think that Naturalize could be a better option than Unravel the Aether ? or you more concerned of God cards? Any thoughts to Scavenging Ooze for future decks that may try to run Athreos, God of Passage or Pharika, God of Affliction as some form of reanimation deck?

Let me know how Keranos, God of Storms works out. I see the combo potential with Courser of Kruphix .

He works the same as if he was used in conjunction with scry at that point. You can set it up as you please. but anything that allows that set up, scrying, courser, and domri all help you get where you want to with him. I find i don't play him as much as i would like to though. It may just be my play style, but since he hardly turns on as a creature I find in this deck there are juicier options to save that mana for.
