What do you guys think of the new walker, lord wondgrace?
Although it competes in another league because of its 5cmc, I think it might be worth trying as sideboard card. Obviously, the first two abilities are perfect for the deck. I also like that it destroys permanents and has a win condition as an ultimate, this can help remove permanents with more than 3cmc like eldrqzos, leyline, humility etc which this deck struggles to remove. It also races jace decently.
