This is a great deck idea. I think it has some real potential.
I have been trying various versions of this trying to make an arena farming deck out of it. For Bronze and Silver, I found that a version of this with 6 Novas instead of life towers, no Feral Bonds and mark of life could usually outrush the arena decks. I am still experimenting with a version of this that drops the life element and uses Shard of Sacrifice to stay alive.
