Sideboard looks great. I can't believe I forgot to mention Leyline of Sanctity! Or that it has gotten so inexpensive compared to how it was. I think I spent close to $90 on my playset.

Goblin Rabblemaster? Synergizes pretty well with Norin the Wary. Either way, cool concept

What about the soul sisters Soul Warden and Soul's Attendant? With all these tokens coming into play, they could be a great source of life gain.

You could possibly cut a single Oblivion Ring for a Stasis Snare. It only hits creatures, and the double could be detrimental to run all 3. But in all other aspects, it's an O-Ring with flash.

Also, since Pillow Fort games naturally run long, would a singleton Avacyn, Angel of Hope be out of the question?

I chose not to run soul sisters in this deck because it is counter to the purpose of the deck which is to altogether prevent damage so life is not of large importance to me. As for Stasis Snare I choose to run Oblivion Ring as an answer to planeswalkers and other non creature permenants. If I need instant speed creature removal I utilize Path to Exile. Additionally for Ajani Vengeant I don't see him surviving for very long and other than his final ability I can say that I require his other abilities so in most cases he would end up as dead weight.

As for Avacyn she is dead weight in hand for an incredibly long time and becomes removed to easily by path to exile. At best I would run Elspeth, Knight-Errant which offers fuel to my decks core but I Favor the removal potential of the other 2 elspeth as I would rather remove than protect.

What about Norn's Annex instead of Archangel of Tithes? It's easier to cast and the cost is more restrictive. Also harder to kill than the angel.

Archangel also stops you from blocking too, which I only just noticed.

Annex is far to easy to by pass as most players would happily pay 2 life to let a buffed creature through. That and you may not have noticed but white is not a restrictive cost for me as I posses only 2 lands out of 22 that do not produce white mana. Beyond that as I require a high devotion to make effective use of my finishers I require the 3 devotion that Angel produces as a lose of which would inhibit my general play. Alternatively angel also triggers my Purporos and impact tremors so I can even use it offensively which gives it extremely versatility and efficiency in this deck. Thankyou though for the comment I alway appreciate seeing constructive critisim and differing view points.

Archangel of Tithes doesn't stop you from blocking. It says "As long as Archangel of Tithes is attacking, creatures can't block unless their controller pays for each of those creatures."

If it said as long as she is tapped, then yes. But it says attacking. And ArchFline is right--Norn's Annex isn't nearly as good as Archangel of Tithes, or Ghostly Prison for that matter. Giving someone the option to pay life instead of mana for attackers doesn't really work.

Yoked Ox is a good cheap blocker. Some older cards with the rampage ability might help as well.

I don't really rely on creatures as my ETB damage comes from token generation. As well I'm most situations I'm not expecting to ever get attacked due to the deck being a pillow fort
