AoS 1500 first in store event

Hey guys,

This weekend I have my first in store event and I'm wondering what you guys think of this list (see picture).
the rounds are as followed:

Round 1: Warm-up: Kill points. At then end of the round, count up the points cost of every completely destroyed enemy unit. The player who destroyed the most earns a major victory if he destroyed at least 300pts more than the opponent, or a minor victory if he destroyed 10 - 290pts more than the opponent.

Round 2: Starstrike.

Round 3: Scorched Earth

My idea was to use the shadowstrike starhost for capturing objectives or taking down lone units or heroes. The saurus for combat and the troglodon wherever i can use him, maybe teleport him to help the shadowstrike with his spittle. not sure about the Saurus Knight weapons... and the astrolith for buffing obviously.

If you guys think I should swap something out, the other units I have left are:
10 Saurus Warriors
1 Saurus Oldblood
1 Saurus Sunblood
