A Mordheim warband is pretty simple to put together and because I have this small number of models that I'm not modifying it really makes my choice easy...

Chief, Sorcerer(using the musician from the unit) 5 PestiGor and a Centigor. Not much to paint and nothing to modify. The biggest issue I've had was to stick them to round bases, which was pretty easy!

Priming with Rust-Oleum Surface Primer Matt Grey

I'm specifically going to base these the same as my Skaven I brought to SCGT 2016
