Yeah that's why I wrote the (?) near Tier 1. I think that when this deck works, it works beautifully but it cares too much on its strategy rather than thinking about adapting to the opponent's strategy. Whatever the opponent plays, all you can do is exert to death. That could work or could not work. I still think that the deck probably uses the exert mechanic to its full potential, but it is just not enough to make it to tier 1, or at least to make it constantly. As you said, there's too many things that this deck can't answer.
