Have any of you made any changes at all to nitewolf's original list in the OP, either the maindeck or the sideboard?
Eight threats just seems way too meager for me, so I cut Sinkhole to play the biggest threat of all time.
From the build in the OP...
+2 [VI] Vision Charm
+4 [MI] Phyrexian Dreadnought
-2 [MM] Snuff Out
-4 [UN] Sinkhole

Basically, you're opting to cut Sinkhole to play an additional kickass threat, a 12/12 trampler along with Vision Charm which is plenty capable of color screwing your opponent.
Regarding the original sideboard, neither the Blue Elemental Blasts nor the Diabolic Edicts seem really optimal compared to options like Pithing Needles (far more versatile) and Misdirections (to protect your threats).
