Harlan Versh finds his way into a lot of my lists. Midwinter I haven't got around to using yet but I am going to get old witch as a new caster and I think he will fit in her list.
I am sticking with the same colour scheme for all my mercs, Charon grey and Hormagaunt purple it works quite nice I think and stands them out from the rest of the army.
Versh has an annoying mold line on his face, I tried to file it a bit but was worried about taking the rest of the detail off, doesn't matter much on the table top as you never see it.
