Warriors of chaos for me. Units of 35 marauders with MoT and LA and shield rock as a army centre, along with 18 warriors with halberds and shields with MoT, great in either offence or in defence. Have done about half the marauders 90 infantry and 20 cavalry so have made a good start.
I'm thinking 3 blocks of 30 maurauders, each with a chariot at their side.
A small block of chaos warriors to support the Lord (for the leadership).
2 units of fast cavalry and 4 small packs of dogs.
And then some anti-magic stuff.
