So, here's my 1000 point
SoB list for a game against guard tomorrow:
Now, there's very little I can change in this list. In fact, this list includes all my models minus four sisters, a seraphim superior and a penitent engine. So, what I'm mainly looking for is advice for how to play them, and things to be wary of when facing him. It's my first time facing guard, after all.
My tactic is to place the Aegis in a horseshoe-shape, with the open side placed against impassable terrain or a building of some kind. Within will be the exorcist, quad gun and the retributors. I know that my opponent is deathly afraid of exorcists (a remainder of the game where I rolled a six for the number of shots three turns in a row

), so it's likely to take a lot of fire.
Anti-air will be covered by the retributors. As this is a 1000pt game, it's not likely I'll be actually facing any, but it never hurts to be sure. For the rest, I'll be using them as a versatile unit, providing either anti-infantry or anti-tank where I deem it to be necessary. For this reason, I'll most likely have them fire last each turn.
The anti-infantry will be the task of both my
BSS and the seraphim with Celestine. I'm hoping to catch some densely-packed guardsmen behind cover with the latter.
Anti-tank will be done primarily by the dominions and secondarily by the exorcist. The exorcist only secondarily because it will probably draw bucketloads of fire, and I'll be lucky to have it survive turn two. However, that will allow my dominions to drive up to his lines relatively unhindered.
I'm somewhat concerned about having only two troops units, but since I don't have any more sisters, that's too bad.
So, any advice?
