When he came out, I built my own lands-matter deck, and... it was okay. Lord Windgrace was acceptably powerful, but just kind of generic. Obviously rewarded fetchlands. Had an acceptable +2 for cycling/generating value. I don't think I ever activated his ult, because it's best when you're behind, but Planeswalkers are the first thing to die when you're behind.
I could play him again someday, but, I suspect something more interesting will appear.
