I got the idea of playing with Desolation and fiddling with land in some interesting ways. With a half dozen Zendikons and 9 non-land mana sources, it should at least be interesting. A lot of the BW stuff I own is hybrid, so I built around that at the core of the fighting component, but the lovely part would be Stuffy Doll with Pariah on it (Demonic Tutor and Enlightened Tutor increase my odds of getting them, too).  The 11/17/11/0/1 curve gives a nice little 2.08 average, and with 70% below the three-spot, this could be quite fast.
