Imho you have a good Counter against the Dragon with Skarbrand, otherwise you could use Slaughterpriest's Blood Boil. About the Skeletons... you need a Lot of Rend 1 wounds to get rid of them. There are several Units who are very good at this: Chaos Chosen, Khorgoraths, Wrathmongers and Chaos Knights with Lances.
I was even thinking in block and then ignore them, with some fleshounds mb. which are cheep and fast and get to unbind. But I' can try to fit some knights. I defenetly don't want to get rid of the 3th priest, I love blood points, and another WoKBT is always good. Or, leave the WoKBT out for the beginning, I can farm 8 point pretty fast.
Mongers are expansive but can defenetly do the trick. I might switch the second unit of blood warriors, but 5 mongers, still, are not many and not fast.
We also are not considering the first round, which with this deploy (bloodwarrior/priests/secrator/reavers) is dropped in 4 .
However, I would highly recommend the Mortal Options. Khorgoraths are nice, gut they cannot bei buffed AS Well as Mortal Units. Mortal Units can gain +2 Attacks ( Bloodsecrator+ Aspiring Deathbringer), +1 to wound from the Juggerlord,+ to Hit from the Slaughterpriests and re-rolling 1s to wound from Mister Whippy.
You think is a good option to leave skar out and let a Juggerlord in?
If you count in these buffs, all three units- Chosen, Knights and Wrathmongers- are able to delete these skellies in one Turn.
As before, I can try mongers, like them.
And remember- you can dictate the enemie's movement with your Slaughterpriests as well- so no Objective camping.
Very true.
Against Magic, however, there is little you can do. The Khorne Dragon has a -3 to Cast...yeah, that's all - to Cast Khorne has.
Not shure if he can stand skeletons alone, in a 2k match, buffed by some priest, might be not enough. (2+/6+ with the warshine is still poor).
Just try to Blood Boil or Lure His casters Out.
