Changes from Adrian Sullivan's list:
  -1 Oppressive Rays
  -1 Azorius Keyrune
  +1 Trading Post
  +1 Eidolon of Rhetoric

  -2 Nullify
  +2 Disperse


I like the idea of early counter spells, but really I think bounces might just be more flexible.  Might be a mistake to cut them though.  Other options to make room for counterspells + disperse would be Keyrune and other copies of Nyx-Fleece Ram / Oppressive Rays.

Eidolon of Rhetoric has just got to be good in this deck, and Adrian likes Keyrune just a little too much.

I want Post for the 4 life a turn.

Additional Eidolon of Rhetoric might be worth slots, but it seems like it'd be bad main deck vs monoblack etc. 

Consider 1-2 Jace 5 for wincon.
