Tried it yesterday with a list with no artillery and only one Strollaz rune, versus a pretty competitive WoC list. I lost (partially to a very stupid deployment move that resulted in my 19 Irondrakes not contributing to the actual battle - ouch) and learned how to futher tweak the list.
Smith, RoStone, Shield, 2 RoSpellbreaking (with longbeards)
Thane, BSB, shield, RoGrugni, 2 RoBattle (with longbeards)
Longbeards (22), Great weapons, Full command, RoBattle (will up this to 29 bodies)
Hammerers (20), Music.&SB
Irondrakes (19), RoStrollaz (will bring this down to 12 bodies)
Big block of Nurgle warrior, with Exalted BSB en Death mage
Charriots (2), some options
Chaos knight of Khorne, some options
We chose ETC2015 table 6 as a battle field. I wanted my death star longbeards to be straight opposite of his warriors, or anything else. I deployed gyro-longbeards-hammerers-gyro-LAKE-irondrakes. He deployed dogs-knights-chariot-warriors-chariot-hellcannon. Vanguarded my drakes up to be in reach of the hellcannon. I send one gyro up to annoy his knights, that worked fine. The other gyro landed next to his canon. Marched up my combat blocks. He moved up (except with units that were blocked by my gyro) and shot his hellcannon. WTF. Big template of S5 hits? Really? He took 50% of the longbeards off - bye bye death start. My drakes shot the cannon, but hitting on six, wounding on 5 or 6, 5+ ward save, I think I did a one wound. These drakes were miles away from where the action was. He couldn't make a safe charge, so he placed his units so that he was "safe". My gyro charged his cannon, and stuck around till end turn 5 . My (halved) death start charged his warriors, these guys were so eager they make the 13" charge. As did my hammerers, they hit the chariot. The Longbeards stuck around to make sure the hammerers (who vaporised a chariot) got to flank the warriors, who broke and got overrun by my hammerers. My deathstar was reduced the the battle BSB and smith (beer drinking veterans) and my hammerers were with 18 guys! Then doom happened ... He finally killed my gryo, and positioned his knights and chariot as an Iron and my hammerers were the waffle. My thane moved from the smith to the hammerers (I know, the b*st*@# left the smith to be a speed bump) and the hammerers faced the knights. The smith rear guarded the hammerers. Ouch..... A charging chariot with D6 S5 impact hits is not funny .... twice! First he ran over my smith, then he hit my hammerers. 18 bodies was not enough to withstand all these S5 attacks, so when the time came to hit back, there were not alot of hammers in the air to hit back. Lost combat, fled (I know, stubborn rerollable), banners exploded, warriors ran me down. The hellcannon got the better hand over my gyro (demonic monster versus excellent dwarven machinery), and had a go at the drakes, killed 4. The drakes then shot the knight to pieces, but got beaten up by his last chariot and hellcannon.
Excellent battle, had a lot of fun, really liked the ETC table set-up, liked the list! I think this set up is viable, to some extend. +3 combat res on top of ranks, SB and BSB is a big shocker for most units.
Lessons 1: alway vanguard the drakes in your opponent most dangerous unit and start blasting. You want this unit to be charged. Their stand-and-shoot will annihilate virtually any quick cav or chariot unit in the game. Thats their purpose imo. It also freaks your opponent out.
Lesson 2: The longbeards need more bodies... took some out of the Drakes, recruited them as longbeards (though they did not see it as a promotion)
Lesson 3: Do not forget Grugni when your opponent's hellcannon rolls 10 wounds on your deathstart.
