i would suggest maybe adding in a Grave Betrayal for things like using damnation. also it would probably be good to replace Reassembling Skeleton with Gravecrawler :)

Have you considered Slave of Bolas ? It seems to fit the theme you're going for.

I like your style! +1 from me! Skullclamp ? works wonders with sack outlets and Bitterblossom . Also Hatred is a cheesy wincon if you have more health than your opponent (or use it for commander damage!). check out my version for ideas and comment/upvote if you feel like it. Thrax the Assassin

@kaleb11 Reassembling Skeleton can be played on other people's turns AND can block (which he happens to do often in this deck) while Gravecrawler cannot, plus I don't have enough zombies to play him as Thraximundar tends to get owned every time he hits the battlefield.

Rooftop Storm = instant Thrax

yeah, Rooftop Storm is kind of really a staple for any thrax deck. you should really run it since it is so good...

@Droxium and @mcm93, Rooftop Storm is such a niche card for the deck that grabs such a huge amount of hate for the limited amount of zombies I run that it's just not worth it. Pretty much it will either guarantee one of two things. One, that I cast it and someone will instantly use removal/counter it, or two, everyone will look at me and I'll be the next person to die. When you play a lot of 4+ player FFA's you'll realize that with cards like these you either have to win the game with them or you just don't play them.

TL;DR, attracts too much hate and it doesn't win me the game
