Oh nice! But I still think the cold one needs to be pumped up a bit. The cold one has sharp teeth and claws. So a bit of rend?
The 1 attack for a Saurus kight stinks.
Yes its nice, but look at the might skullscrushers warscroll
https://www.games-workshop.com/resources/PDF/AoS_Warscrolls/aos-warscroll-skullcrushers-en.pdf
They do D3 wounds on charge on a 4+. And they have nice attacks, and 5 wounds. Obviously there are only 3 of them, and I wound not expect the Cold One knights to be that powerful.
But the 6+ mortal wounds on charge to wound not even on hit rolls, is basically a waste of time on Cold One Knights, as you normally only have 5 of them in a unit, probably not all of them will get to attack. Seeing as their lance has a 1 inch range wtf?
Your telling me, Grimghast reapers have a 2 inch range with their scythes, but cold one knights with long lances don't?
I think your warscroll is nice, I would say 120 points for 5 models. At the moment I have used Cold One knights, the 5 + save is trash. So they are not survivable, they do no damage and they are slow as well?
They should be good at least one of these things. Your Warscroll is really nice with the 4+ save, 3 wounds and 2 and 3 attacks.
1 attack for the rider and 2 for the cold one, all with no rend. Why would the Old Ones even bother wasting their time designing such crap.
