I also play an Avacyn Deck except mine is centered around board wipes, and land destruction. It's basically board wipe tribal lol. If you have time you should totes check out mine. As far as it goes we have two very different ideas on playing the deck which is cool.

Avacyn, Angel of Hope

I like it. Have you considered these two? Angelic Destiny and Angelic Armaments? They are two of my favorite angel themed cards.

BringerOfStorms I hadn't actually. Destiny slipped my mind and I'd never actually run into armaments before. Definitely gonna look into making some room when I have the time, for destiny if only one of them.
