I am finding that the Eldrazi control cards are the real deal. The biggest pay off of the processors is Ulamog's Nullafier and there seem to be plenty of great early interaction cards that exile to set it up. Besides Horribly Awry, Fathom Feeder, and Complete Disregard, Silkwrap slots rather naturally into this sort of deck. So far it seems quite effective in my early testing but I am looking for some feedback.

Trying to avoid adding Jace though I would agree that he might fit well in here. Since I play a lot of reactive spells, his -3 is not nearly as potent as it could be in a red deck.
