Well, this deck has come a long way since I first built it.  Much help from a friend.  Birthing Pods, Elesh, and Sheoldred were definitely not in the first edition.  Slash Panthers, Metamorphs, and Pristine Talismans along with some other cards came out... Birthing into an Elesh turn 5 comes up quite frequently.

Generally speaking, I find a deck with too many 2-ofs to be pretty inconsistent. Your strongest cards in this theme are probably Metamorph, and Dismember. Because you're primarily relying on a 5-mana artifact and then casting stuff to win, I'd recommend shifting toward control and away from aggro. Tezzeret's Gambit, Gitaxian Probe, etc. (you've already got Norn's Annex). 

I'd probably lose the Blessings, Shards, and Mirrorworks to start.

Well, played this deck at MNCasual.  It dominated a couple other casual decks but when played against decks made by a really good play, it didn't hold up so well.  He suggested that I sub in some Sylvok Life Staffs and maybe some card draw.  So I will pull the Vault Skirges to add in a couple Sylvoks but I have to figure out how to get some cards in here for card draw.
