I usually like running units of 15 and use them to go against other units. I usually have 2 tzeench warriors with 1 unit of khorne. the tzeench warriors would be my anvil while my khorne will do the butchering. i also have units that go around them like chariots, hellcannon, shrine, chaos lord and sorcerers. it works pretty effective for me. just need to give them jobs to kill
