Playing around with some lists for a small tournament next weekend. Currently I'm looking at this.

Sorceror lord-Lvl4, Preservation, Blood of Tzeentch, Conjoined Homunculous, Enchanted Shield, Stream of Corruption

2+/4+ Saves, decent in melee, and should be able to cast something terrible out of the Lore of Shadows.

Hero-BSB, Book of Secrets, Dispel Scroll

Main job is to help Lord warp around with the Lore of Shadows cantrip, and to carry around a Dispel Scroll. Other than that he'll hopefully prevent a few Berserker charges.

15 Chaos Warriors-Mark of Khorne, Halberds, Full Command 300
15 Chaos Warriors-Mark of Khorne, Halberds, Full Command 300
5 Chaos Knights-Full Command, Banner of Rage-285
I learned from my last 1600 game that I played that being able to move more than 4 would have been very helpful.

Warshrine 130

Other things I've been considering is dropping the BSB and stripping the Lord down to basics to either add another Block of Khorne Warriors or a 10 man block of Khorne/Tzeentch Chosen. The other option is dropping magic entirely since I don't really like my spell options on a basic Sorcerer. The Lord may be expensive, but Lore of Shadows is at least fairly versatile.
