Exciting battle ahead it looks like. Do you have any idea of what sort of units he/she likes to field?
Regardless, Vampire counts have no shooting, which helps our Hammerers for example, and GW Warriors. But do we do need to watch out for a few things, so let me recommend a few edits.
In general, the Lords/Heroes all should get new runes.
Let's start with the thane:
So here, we can choose to put a rune on the banner, or on him. Many here choose the Master Rune of Grugni because of the 5+ ward against shooting and4+ for the wearer. However, Vampire counts have no shooting. So you could instead go with the Master Rune of Valaya for some magical defence (+4 to casting, so it acts as if you had a lvl 4 dispelling).
If not, you can tank him out with something like3x rune of Warding (4+ Ward), Rune of Stone, Rune of Iron. This makes him very surivable.
Can't do both as it's either the banner or him.
Master rune of breaking - if you meant the Master Rune of Spellbreaking, then yes.
if you meant the Master Rune of Spellbreaking, then yes. I'd maybe even do 2x Rune of Spellbreaking, Rune of Stone, Shield. That gives him a dispel scroll, a chance to eat the spell for the remainder of the game on a 4+, and a 2+ armor save.
for the Master Engineer, I would look at giving him a brace of pistols for the stad and shoot and extra attack, rune of stone, and that should be good enough to keep him on the cheap. I assume he'll go with an Organ Gun?
On to Core:
Dwarf Warriors x 30 w full command and great weapons
Good all round. And since there's no shooting, this is good.
Longbeards x 20 w full command
- Great! Could give him the rune of stoicism to make them stubborn. But consider upping their numbers a bit. Maybe 25-ish?
Thunderers x 10
Thunderers x 10
On to Special:
Rune of Forging
Rune of Forging, Rune of Burning
Runes are good. But do we need two cannons? Vampires can field a Terrorgheist (or 2), Mortis Engine and not much else that's competitive in terms of large monsters. Maybe 1 might be enough. If not, keep both. All good!
Hammerers x 20 w full command
I like! do you have more? A horde of 30 can be very good.
What I notice here is lack of Ironbreakers, and Gyrocopters. My recommendatino would be to drop a cannon, and add 1-2 Gyrocopters. Great for things with regen and vs Grave Guard.
Onto Rare and I see the Organ Guns. I can never say no to Organ guns. I love me some organ guns.
What you could do is try to add a 2nd Master Engineer, and part each organ gun with accuracy and an engineer. Nasty stuff, but also could be seen as starting to get a bit... emmm.. "mean". I don't know how well you know your opponent, and whether you like to play competitive games, or not so much.
Beware a blender lord with Vampires - he/she will have red fury, quickblood, and I cant remember what else. He can dish out a lot of pain.
