The move doesn't make a whole lot of sense. It encourages people to play more Moxen and fewer creatures that attack and block for small chunks, which is the opposite direction this format needs to go. I'm hoping I'm not the only one to whom that is so baldly obvious.
Plus doing this suggests that whining is rewarded over logic/reason, which I guess I shouldn't be surprised by when Chalice/Lodestone caved, but it still rankles.
Nevertheless. First-turn-kill combo didn't get appreciably better. They didn't do a ban. They didn't restrict any of the really critical stuff like Force of Will. They didn't unrestrict any of of the real critical stuff like Lotus Petal. I suppose we should chalk it up as a small victory that the format isn't smouldering in ashes right now.
