Ok, thanks. My play style is very flexible - I tend to just respond and attack rather than heavily strategise. I have 10 skinks, 20 saurus, 15 saurus knights, 10 saurus guard, 1 stegadon, 1 stegadon with Eotg, 1 Oldblood on carnosaur and 3 terradons (with bolas as their weapons).
Ideally I would like something which has an anti-chaos buff as my brother is a Chaos warrior, and he is quite strong physically but his tactics are awful. They consist of shoot at stuff, charge at stuff and fight stuff, so I need some special rules that can really mess up his "strategy".
I was thinking ark of sotek as a ranged attack in the hero phase could really confuse and weaken him. Also, I have a knack for rolling 1s and 2s when I need to.
But searing beam is mental! Summon in a bastilodon nine inches away from a monster and blow it into oblivion! But I was expecting it to be more useful in combat though.
