82 Darth Bane
24 Mistryl shadow guard
11 Human Bg
5 Caamasi Noble
27 Lobot
-11 Human Bg
-9 uggos x3

149 points, 9 activations

want to use bane in a 150pt tourny coming up, basically trying to keep bane alive while he takes out the enemy

I find that Bane is probably not enough, While you have given him an extra 100 hp, there is not enough Damage output per round to justify him as an offensive option. you need a secondary threat.

ok hows this:

Darth Bane 82
Mistryl Shadow Guard 24
Lando Calrissian, Dashing Scoundrel 18
Darth Sidious Hologram 11
Caamasi Noble 5
Ugnaught Demolitionist x3 9

Total Cost: 149 8 acts

Holo Sid is basically wasted points, because Bane already has renewal. I don't think that 150 is the best format to play bane in, he really shines in 100 point games.
