Hrm in honor of the Warriors of Chaos army book coming out in November, and seeing as the Captain has seemingly beaten me to calling the WoC lists, I'll do up another set of lists with a different god focus for you
. Since Sarathai wants Nurgle, I'll go for either a Mono Tzeentch, or perhaps a Tzeentch/Khorne or Tzeentch/Slaanesh mix.
