I feel like both Deathrite Shaman and Shadow Alley Denzine are both better options then Tormented Hero, and 2 Corrupts to replace the one copy of Rakdos, and Dark Prophecy. The Tymaret is cute though. good call there. I'd also recommend another two Doom Blades and side out the Thoughtseize. (and four in the sideboard along with Pithing Needles)
Lastly, I'd say get rid of the Nykthos entirely and one of the Guildgates, and get another 2 swamps.

I'd also say, Read the Bones over Underworld Connections.

hey joz - read the bones isnt a permanent, and it just slightly worse than underworld connections because of gray merchant. deathrite is cool, but w/o sac land all he does is burn for 2 on sorceries...tried it, not impressed. denizen is also worse than hero because you REALLY want to be dealing extra dmg w/ your 1 drops. remember - you are attempting to kill them with the gray merchant.
