Debut of newly build Seluicid army. They are formidable force in paper, having very strong cavalry contingent and much stronger ranged units than Romans – Republicans incidentally have only velites.
I did have a plan – I would have the sarissa armed phalanx in two large units. They are quite poor when standing alone and best use is to keep them as roadblock. Of course I thought to use the cataphract elephants to punch Roman legions a bit, grind the remains with cataphracts and then mop up with phalanx. Archers would support from a far and peltasts would keep the enemy off the flank since the cavalry is hopelessly one sided.
Unfortunately short bows are not that efficient – which is hardly a surprise but they appear to be pretty good for picking enemy cavalry. Peltasts are essentially like any other light infantry, and would benefit from some hindrance.
Elephants were not used to most of their effect, albeit Romans did end up charging them and they served well to the end. Next time I think they could be used against legions as well as cavalry. Seleucid elephants are really powerful.
