I have never played before, but just got a lot off of ebay, so what I have compiled so far is

2 fall of the jedi

2 web of the Emperor

2 agent of the emperor

2 the executor arrives

I'm arguing in my head between

2 Counsel of the sith

or

2 Killing cold

For more control card draw, and resources Counsel would be great

Killing Cold offers more triggers for Executor, control of force balance and both offer twist of fate. so being a noob where do i go?

Two Counsel of the Sith is good. That's what I have in my deck and I was able to win local tournaments with it. But like I tell every new player who joins us and doesn't know what to do in my area, try different combinations like I do and see what you like the most. =)

Every time I try Killing Cold over CotS I end up disappointed, for whatever that's worth.

Try Killing Cold with more Hoth objectives. The Desolation of Hoth is killer.

Try this too for a Mono Sith deck

Vader x2

Emperor x2

Jarric x2

Sariss x2

Council

Executor

I also run this but minus Council and Executor and put in Tat Crash x2. It's just not Mono Sith obvioulsy
