Alright so I'm satisfied by how the 750pt list is looking now I'm ready to build on that

Characters:325pts
Necrarch Thrall: Noble Blood, General-125pts
Necromancer: Lvl 2-100pts
Necromancer: Lvl 2-100pts

Core: 430pts
18 skeletons: Standard Bearer-154pts

9 ghouls-72pts
5 direwolves-50pts

Special: 245pts
4 fell bats-80pts
5 Black Knights: Barding, Full Command-165pts

I was thinking maybe I should drop a necromancer for banner of the barrows, an extra knight and the book of arkhan for my remaining necromancer. notsure though if it's worth the magic levels.
