I'm really struggling to come up with small point lists for my Nurgle warriors. Mainly at the 1000 point level, i plan on using Festus but if I fit in a BSB then I'm limiting my options. Any ideas?

I have the following models available:

Lord on foot
12 nurgle great weapon warriors/chosen
26 flail/GW marauders
10 forsaken
5 war hounds
3 nurgle ogres
