Good morning,
I had to google what an Escalation League is and must say it sound's awesome! I can imagine it helps greatly with motivation, wish my Playgroup had held one.

The Scarnosaur has really good pointvalue and is strong without much support. Together with your Skink Starpriest you can make two Units of Kinghts really scary with the Scarvet's CA on one and the Starpriest Staff on the other. Saurus Knights are the way to go in KC and 3x five Knights could be your battleline even in a 2k points army. All Units here are a solid foundation to expand your army on.
Beware of your Skink Starpriest, between him and the Sun, he is a clear target and at 750 points you dont have much units to protect him. With the Purple Sun out he can deal a good amount of damage, still it could be the better move to cut the Sun and get 10 Skinks to give him a screen.
