Ar'kazail Out!

Looks decent to me. You might want to try ghouls in units of 9 though they work best in that number (takes more to panic them)

Combine the knights. 5 is far too small to be a hammer.

Make the bunker into a straight zombie necro bunker.

I, personally, would switch the thrall to a periapt/scroll necro, and then switch the count to have NNB, Dark Acolyte, cynosure, and biting blade.

And get another magic level on the count. Why get NNB when you haven't even purchased the regular upgrade. Which is cheaper.

Get an extra ghoul in each pack, and sling musicians in the big skellie units.

leaves you at 1995 points with an additional 3 models, 3 more PD, 1 more DD, and another scroll.

Oops sorry I forgot to purchase the normal Lv:2 upgrade for my count, so I will % skeletons from the unit of 10 to pay for it.

Then since you cant have a unit of 5 I will use the remaining 65 pts to add 2 ghouls to eack ghoul unit(48 pts, so I have 17 pts left so i will.....I dont know what to do with the last 17 pts.

I want to keep my count having the ring of the night for the ward save, so I dont want to get rid of that.

I dont like taking knight units bigger than 6 because they tend to become the attention of every war machine, gunline, and spell my opponent has. And I think that having 2 units will force him to seperate fire on two different targets (plus I dont tend to have any luck with knights in general, let alone big units)

Small units of knights should be unbarded and largely free of anything outside of a standard bearer. Cheap flankers is what small units of knights should be used for, nothing else.
