I've thought about it... the reason I hesitate to put Jitte MD is that we don't have all the fliers of Esperblade. Put a Jitte on a flier and go to town. Put a Jitte on a Snapcaster or Mishra's Factory and you're trading creatures for Jitte counters. That's fair in some cases, but UW has so few dudes that it seems better to suit up with Pro-Green and just get in there. Against the Esper builds, it just seems like a matter of bringing in some Surgicals to deal with Lingering Souls and saving your Brainstorms for their discard.
