First of all, welcome to the forum!
Now, let's see what we can do with your models (pick asap a bastiladon!

)
Bloodclaw starhost (100)
Saurus oldblood general (100) if you face shooting or long range abilities, protect him with something as "legendary Warrior", "master of defence", "Phoenix stone".
Saurus Sunblood (120)
Saurus scarvet on carno (260)
Saurus Scarvet on cold one (100)
30 x saurus warriors 300 (your main hitters, that will roll the battlefield at the center, and will be able to suffer casualties from mortal wounds given their number)
5 x saurus Knights 120
10 x Saurus knights 240
Shadowstrike Starhost (120)
Skink Starpriest (100)
5 x chama skinks (120)
5 x Chama skinks (120)
3 x rippers (140)
Total: 1940 / 2000
The shadowstrike will be your deep strike utility, then harassement / objective taker tnx to chama skinks
The bloodclaw will be the bulk of the army:
All the 4 heroes will be able to use command abilities, which will buff to stars you main troops. remember that the ability of the oldblood afoot, will give you basically a 3" additional movement, thus taking (for example) saurus warriors to 8" instead of 5". pretty fast.
The warriors will be your main hitters, that will roll the battlefield at the center, and will be able to suffer casualties from mortal wounds given their number. I woul like more than 30, but hey.
Basically, your block of saurus will march at the center as fast as they can, with knights on the wings, protected by the magic of the starpriest and buffed by all of your heroes' command abilities.
Rippers will snipe some key target, and skinks will harass the enemy or take objectives.
And with 2 battalions, you will be able to pick additional artefacts for your melee heroes!
You still have 60 pts to spend:
1) some meta allow to take partial units, in this case you could field also the 6 remaining warriors for 60 pts and have a nice block of 36 fighters.
2) Another option for those 60 pts would be to proxy a salamander, or use a skink chief for objectives control.
3) Or use the oldblood on carno instead of the scarvet (losing a buff to troops, but gaining buffs for heroes)
