Aside from the Angel weakness, I would say you look like you have too many artifacts. I haven't seen the deck work, but is Hezekiah's Signet Ring really necessary? It looks to me like you will almost always have a better artifact to have active, especially with 2 Nazareths in the deck.
Is there a reason you don't have New Jerusalem Dominant?
You also might want to consider Site Access, I don't think it will be a dominant strategy, but most T2 decks will probably have a few sites that can at the very least get annoying, I would consider and Ends of the Earth or two.
