MTG Salvation

It might have been mentioned and I could have just missed it, but Varolz, the Scar-Striped and Death's Shadow seem like too juicy of a combo for this deck to pass up, especially with Skullbriar.

I think hardened scales would be a good card in this deck

only costs 1, works really well with SB, can be cast turn 1 into SB turn 2
1/1 - 3/3 - 5/5 etc instead of 1/1 - 2/2 - 3/3
