Ok so, I like this deck.


First off all, Cry of Contrition is amazing off of Augur of Skulls. I'd bump both of them to 4 of's.


Second, Hymn to Tourach is strickly better than Wrench Mind in my opinion.


Bump the Liliana's Caress to 4 and drop Megrim - it's shittier.


Replace Hollowsage with Liliana's Specter.


I don't like Victim of Night as removal. Maybe Tragic Slip as it combos well with your Augur.


Painful Quandary is an awesome board stopper late game. Makes them make the decision: "Should I play the spell and lose 5 life, or keep my card....that I might be forced to discard anyways". Very powerful.


Tyrannize is not good enough. That late in the game they won't have any cards left.


You have a ton of discard sorceries, which I think may be overkill.
