What my buddy did was like this:
BA chaplain with super black space marines
Inquisitor Lord with guns and little guys with more guns
A bunch of them daemonhost things
2 squads of stormtroopers with dual plasma
a squad of sniper scouts with a veteran sarge
a couple squads of las/
plas BA with a veteran sarge
2 predators (either all las or he might have converted them to baal now that ass-cans don't suck)
Dev squad with missile launchers
He had some other crap I forget, and it wasn't a great army - but he did OK with it by using a lot of finesse and luck with those daemonhost guys. He might also have had a callidus assassin but I forget the rules
tbh
