With Mawtribes you've got the two stonehorn heavy lists:
Firstly with a 6 model, but 6 drop list.

Secondly, you've got the one you see mostly when it comes to beastclaw lists, the Eurlbad list(or Jorlbad for less pts and a more likely triumph). It's 4 stonehorns instead of 6, but 3 heroes instead of 2 - and you've got some kind of screening in your mournfang and their huge bases.
