This  deck can be utterly devastating, but it could stall out with no defenses to speak of. I decided to use Crosstown Courier instead of traditional unblockables, and that seems to be a limitation, though when it is working and paired with Trepanation Blade and Mindcrank, the effects are huge. The real risk is that this tries to do a few too many things and doesn't do any of them as well as some others, but it manages it in such a way as to be a serious threat. The 15/13/11/1 curve is insanely low, averaging 1.95 only.
