Looks great! +1

Also, those alters look pretty awesome

Pretty cool deck! I have a similar Angel deck based on Eight-and-a-Half-Tails.

My one suggestions would be Story Circle. Perfect against everything but Eldrazi.

I've used Story Circle before, didn't quite work for me, often times it's less than effective in a 4 player pod.

Interesting and cool deck. I'm actually thinking of buying it.

Have you thought about putting in Silence for extra protection. I would also highly suggest putting in an Isochron Scepter, that way you can cast cards like Dawn Charm, Ethereal Haze, Holy Day, Path to Exile or Swords to Plowshares every turn to add an extremely frustrating lockdown for your opponents.

Isochron Scepter wouldn't stay on the field for very long, i'm not allowed to have nice things apparently, lol.

so Moat

Restoration Angel

Would be worthless because this deck is angel tribal?

and moat costs more money then i'm willing to spend.

Ever thought aboutMana Tithe?Really a surprise against combo decks, which is most likely what you will lose to most of the time. Also, i believe this deck is a bit low on draw, not sure what to run to get that in this.

Also, Eerie Interlude can save you so well from certain exile boardwipes

I love this deck. My favourite card will always be Avacyn, Angel of Hope (I bought a copy of V15 because she was in it (and I am poor too)) so I always love an avacyn themed deck, plus the not dying theme also sounds cool. I have to add, I do love those alters, they look great.

A few more protection ideas include Gift of Immortality, Favorable Destiny, Mask of Law and Grace, Crown of Awe (although both don't help against black removal, Martyr's Cause, Kami of False Hope and Mother of Runes.

Maybe Heartstone for a discount on her abilities and Eight-and-a-Half-Tails to make colorless sources white.
