Hi, I usually play with two friends using ironjaws (dealing with the maw krushas is terrible) and slaves to darkness, and i'm quite noob with the lizard guys. the lists that i'm trying are not working. Can somone help me building a list if I tell you all the miniatures that I have. thank you very much.

eotg stegadon
skink chief stegadon
saurus eternity warden
10x saurus guard

20x skinks
2 salamander hunting packs
2 bastilladon with solar engine
3x terradon riders

(i also have the warhammer underworld lizard pack)

I've tryed koatl's klaw and thunder lizard.... I need a 2000p list, i know i'ts a bit much to ask, but i'd apreciate the help.
