[AreaOfEffect]

Well, I excluded Ashdod from the my example mostly. Ashdod shouldn't have to worry about counters to it's own troops. I also excluded nations from other ages. Ideally you would want to choose Marverni. Your also mostly wrong. Only the Talmai Elder could have E3S1, and his chances are 1 in 120. You however could easily find Zamzummites with E2S1. Cast Summon Earthpower and your set.
