Welcome to Librarium Online!
This is my list i've been using recently, what do you think? the only change iver been contemplating is swapping out the Exalted Hero's power familiar for the dragon helm and a spell familiar (but that is kinda counterproductive to the 3rd eye).
Chaos lord, MoT, Axe of Khorne, talisman of preservation, charmed shield, barded steed. 339 pts.
Sorcerer Lord, lvl 4, MoT, Disc of tzeentch, Enchanted shield, Golden eye of Tzeentch, Infernal Puppet, Bloodcurdling Roar. 405 pts.
Exalted Hero, shield, MoT, Book of Secrets, Power Familiar, 3rd eye of Tzeentch, Battle Standard Bearer. 205 pts.
17 Warriors, MoT, shields, Musician, standard, Blasted standard. 350 pts
12 Warriors, MoK, shields, add. hand weapons, musician, standard, Razor standard. 297 pts.
6 Marauder Horsemen, Light armour, Flails, Musician. 102 x 2 units = 204.
12 chosen, MoK, Shields, Halberds, Full Command, Wailing Banner, Favour of the Gods. 375 pts.
5 Knights, MoN, standard, musician, Banner of Rage. 295 pts.
Hellcannon. 205 pts.
Warshrine, MoT. 150 x 2 units = 300.
Total - 2995
I think the Lord looks good, and I think the sorcerer should be OK too [Golden Eye stops so many magic spells & is awesome against anything that shoots], just keep him well hidden from cannons I'd say.
I agree about the exalted not needing the familar, he has third-eye which is enough for knowing lots of spells anyway. I'd give him Collar of Khorne and a halberd, and drop the shield.
Chosen are awesome with MoT, +3 wardsave against everything?!
Your knights look like good fun, if you get Fear on your target, it's party time!
Overall, I really like the list, especially your Lord & Hero builds. Just lacking a bit against magic, but that is why I suggested Collar before.
