I doesn't seem to have the early board to make the trades to support Volcanic Drake nor to make Abusive Sergeant or Power Overwhelming reliable (i.e., it's draw Egg or bust). It doesn't seem to have the taunts to support, well, not dying. It doesn't have any big swing plays, like free 8/8s. I don't get it? How is this not terrible?
