I think you may be missing a card; you included you general in the list and it adds up to 99.

All fixed!

Have you thought about running Endless Ranks of the Dead ? You have enough zombies to make it relevant when you can cast it and it just gets nasty quick.

I have actually run that card before in my old playgroup and it was full of board wipes. I may include it again because I have changed the number of zombies, I just need something to cut :p

No Sanguine Bond to go with your Exquisite Blood ? :P Sheoldred, Whispering One and Spell Crumple will help you out a bunch. Sheoldred makes your opponent sac creatures which will superpump thrax, and spell crumple is a counter that you can use endlessly given that you draw and shuffle a bunch.

Sheoldred, Whispering One and It That Betrays . That does work.

Not a fan of Sanguine Bond with Exquisite Blood because I don't like infinite combos :P I have thought of the Sheoldred idea, however she is occupying a slot in my other deck. Spell Crumple has eluded me considering I can't find it in my massive piles of cards. XP

Sadness XD

Mox Diamond for a faster early game

Treachery - free creature woohoo!

Force of Will /Mana Drain if you can afford em, if not then Pact of Negation is always good

Contamination and/or Braids, Cabal Minion for control. Keep it going with Bitterblossom , Reassembling Skeleton or Kher Keep

my variant: Thrax the Assassin

Oh gosh, thank you so much! Yes, unfortunately this is a paper deck and there are a lot of cards I need to acquire, but I will definitely look for the suggested cards in the future!

Each time your commander comes out of the command zone you need to pay the extra +2 colorless mana, Rooftop Storm only makes the usual casting cost free. Still a big discount though.
