Suicide Black

[Duel]

Okay, so I just finished my suicide black deck. It needs some improvement (why I'm writing in) but is generally very effective. The deck cost me a grand total of $10 and consists of

4x Dauthi Slayers
4x Dauthi Horrors
4x Preist of Gixes
4x Carnophages
4x Dark Rituals
4x Lotus Petals
4x Grave Servitudes(or Twisted Experiment)
4x Unholy Strengths
4x Scare Tactics
2x Bad Moon
8x Swamps

Any suggestions for additions/replacements?

Yeah, put in Parallax Dementia in instead of Grave Servitude. I've heard it's an excellent card.

Also, don't you mean 18 Swamps?
