 Unicorn Paladin, I'm calling it now.

I've played a very similar deck and my advice is that Murloc Tinyfin is hard to pull off without any extra card draw. I've gotten around this by running one Murloc Tinyfin for every one Coldlight Oracle. You need some way to pull those Divine Favors when they're in the bottom half of your deck.

I like one of Argent Protector in murloc decks to promote synergy. Running Steward of Darkshire without Murloc Tidehunter seems like a missed opportunity, especially when you need 1/1 murlocs for your Hungry Crab. Even in a deck like this, Hungry Crab might still be better as a one of.

Surprisingly, Tirion Fordring fits pretty well in a deck this size. You might want to test it out, but I think you could easily work one in.

My prediction is that, for this deck to succeed as a tempo deck, either Zoobot or Menagerie Magician should be cut. We'll see as time goes on, but Zoobot is the one I see making the most consistent impact.
