H: Phyrexian obliterator, grove of burnwillows(promo) W: to trade them

I'm just looking to trade away the obliterator and the grove atm, I'm mostly looking for Jace belerens and a few other things for a modern murica deck.  But i'm also interested in just equal value of things in standard or modern.  Just let me know if you're interested and if you have some value cards I'm sure i'll be interested in them.
