Hi. I am probably starting CSM soon, but I am unsure which God to follow, or if I should go for undivided.. My main enemy will be Necrons, but also some Ultrasmurfs, and on rare occasions, Eldar (not dark).. I do not want Nurgle, and I like Khorne and/or Tzeentch the most, but Slaanesh or undivided might be acceptable.. Any advice would be appreciated
