I would try running Bring it On / Shield in a Control deck. Use it mid to late game to block your opponents creatures and keep yours safe for a turn or two.

As for Thariel's Scale, I'm not too sure about that one. Sure, there are times where it could be a useless 7 mana card, but there are other times would it could just be an extremely frustrating, toxic play. I think there needs to be some sort of negative side to it (aside from mana cost), though I dont know what that would be. Maybe something like ' Destroy your God Power'? But then it might an extra buff. Perhaps give Ward and/or Protection?
