I've been tuning and tweaking my Vorosh deck for EDH (U/g/b) for a while now and thought I'd get some community feedback on some of my card choices.

The deck is pretty much U/g control with a black splash for some extra removal and multi-player cards. When I get bored, I'll probably drop the black splash for white. Most of the black cards have equal (or better) functional replacements in white, plus I'll get marginally better mana (Obelisk of Bant, Seaside Citadel, Bant Panorama) and be able to open up Alara block, which has some great cards for EDH. For now though, Vorosh it is (my favorite color combo).

I should note that I have this deck sleeved up and ready to go, it's not a just on paper. Other than getting a few must-haves (like Damnation and Verdant Catacombs), I don't plan on picking up anything that costs more than $3-4 or so for now (so no Watery Grave or Overgrown Tomb), but if it's awesome, I'll add it to my Want List.

A lot of care has been taken to balance spell vs. creatures, mana curve, colored mana requirements, etc. so I'd rather not make large changes without revamping things (mainly the mana).

Cards that I'm not 100% on get a "?" Cards listed in blue/brackets are cards that that I plan to add in place of the cards not in brackets.

So, what am I missing and what changes would you make?
