Could not find the exact list but , I am willing to bet it was one of the fallowing
fateweaver, blood thirster , 2-3 big units of crushers with wound allocation, couple of plague bearers maybe a unit of horrors 3 daemon princes of nurgle or tzeench.
4 heralds on chariot with bolt and maybe breath / master of sorcery
2-3 units of fiends, 1 unit of flamers couple of plague bearers maybe a unit of horrors 3 daemon princes of nurgle.
Only things that change are hq and elites mostly.
