Back to Treva, the Renewer !
I think that Treva is a cool commander for exalted because of the ability she has. Using Rogue's Passage or Jhessian Balmgiver, you can make her unblockable, and she kills in four turns. Also, gaining life could be interesting, though what color to choose could be hard....
id run a Martial Coup for the tokens and cause you have Sublime Archangel the tokens gain exalted boosting treva for the win and id also put in a Rafiq of the Many cause he'll give a creature double strike making your commander a one hit killshot
I don't like Martial Coup because I can only get four Soldiers without destroying my other creatures. It's not worth it to me.
