If I added blue, I'd rather use it for the countering than take up Black's slot for whatever purpose it'd serve in such a deck 
But I just throw out ideas from cards I remember; since my playgroup broke up a couple of months ago, I haven't actually played Magic in a while (except for on the forums here) so I'm not really devoting the energy needed to make such a deck analysis worthwhile as you guys do with Making It Work
