­Forest (new phyrexia if it matters) + Living Stone

Buff and animate statues and walls. Nice. A global Animate Wall. I'm not really sure how to make that green though. Green likes to animate lands; could do that? Nature's Revolt tells us both we can do it, and it's already been done.

How about going the other way - green likes to return artifacts to the land. So de-animate creatures? Um, the wording here is ugly. But meh. The idea is pretty clear. Articfact creatures stop moving; other artifacs become nothing more than stumbling blocks. The toughness boost both gives a more wally-form for things, and also keeps non-cretaure-artifacts alive (and nicely turns them into a Wall of Wood).
