AoS Bloodclaw Starhost question

[SimonDread]

Bloodclaw starhost consist units:

• 1 Saurus Oldblood, or 1 Saurus Oldblood on Carnosaur
• 3 Heres of any combination:
[Is that means tha we can choose 3 SV on CO or not so]
Saurus Sunblood, Saurus Scar-Veteran, Saurus Scar-Veteran on Cold One, Saurus Scar-Veteran on Carnosaur, Saurus Etenity Warden
• 3-9 battleline uniits

Is that the mistake? They mean Scar-Veteran with Battleline Standard from Lizardmen Warscroll, witch is Saurus Astrolith Bearer, the only one Scar-Veteran without mount in Seraphon battletom.
Actualy it there Is a 6th ed and 8th model of Scar-Veteran on foot with melee weapon, but Im not shure they thought about this ones.

If those models are usless it would be easy to convert them to Cold One Riders?

 

[Bowser]

Sayrus scar-vet is a mistake. Should be Oldblood on foot. Otherwise any combination you like. If you want 3 scar-vet on cold one then absolutely have at it.

 

[SimonDread]

I will get
Scar-veteran on Carnosaur
Scar-veteran on Cold One
Oldblood

And
20 sourus guard
20 Saurus Warriors
10 Saurus knight

Got too
Stegodon
Bastiladon
3 terriadon
10 skink chameleons

Is that any Good base for bloodclaw starhost?
Wich should be 4th hero, eternal warden, Sunblood, or another oldblood
