Sith Team? But a Weird Version.

Hi, all -

I want to throw together a decent Sith team, but I'm not talking about an arena team. I'm talking about a team to have around for use in TW and TB. I'm a little rusty on my Sith and these Sith are a little rusty now themselves, so I'm counting on those of you who used to be all about the Sith back in the day to help me out here.

NOTE: Palpatine and Vader are unavailable as they'll be hanging out in my Empire Team for TW/TB.

Possible Ingredients: Maul, Oppress, Nihilus, Trooper, Assassin, Sion, Count Dookie-Poo-Poo, Sidious.
*EDIT: Ha, it stars out my nickname for Count Dooku. Classic EA.

So: who's my leader? And who is kind of 'necessary?' And who can I for sure leave out? The best I can come up with is Maul (L), Nihilus, Trooper, Sion, and... you know. Someone else. Am I on the right track, or should I be going for Nihilus (L)? And who's the 'someone else?' And who really, really needs to be Zeta'd?

Thanks!

SamUX
