Centaur Healer is a champ against zombies, granting 3 life certainly takes the edge off their rush and being a 3/3 allows him to block up to half of their creatures safely, and successfully trade with almost all of them. Great sideboard option for those running WG.

yeah the elixirs in the sideboard I could see easily becoming healers, I tried them mainboard for a good 25 games, but I found the healers to have been lackluster against w/g aggro as Rancor lets any of their creatures able to trade with them and a lot of their creatures are simply huge, but I can easily see them doing work against zombies. I've also decided to try out Redirect simply because there are a good number of strong removal spells going around and quite often a Redirect can act as a two for one version of card:Faith's Shield

after reading http://magic.tcgplayer.com/db/article.asp?ID=10749 I think I'll try out Deathrite Shaman in this deck, currently there's just one (because I own just one and since this deck'll be the one I'm using for states I'll have to be realistic while testing) but I do plan on finding more room so I can have 3-4 mainboard, the green ability will probably be the most used, but jace can help fuel the shaman and Abundant Growth can help me with his black ability.

I suggest Snapcaster Mage s for terminus and verdict if you need

I actually haven't touched this since states and it's simply still up here mostly as a reference in case I want to try a better version out sometime.
