Given how the game went over the course of 1.5 rounds (my Ironjawz opponent conceded in the middle of the first combat phase of Turn 2), I could have instead gone with Thunderquake Starhost and would barely have changed a thing about the army I was using.
The biggest takeaway I had from the game is that Ironjawz fall afoul of the debuff game way too hard.
Saurus Warriors, even left on their own and not contesting an objective (can't really do that against Ironjawz anyway, mind you), are tanky enough to hold their own against even big monsters. 340pts of 40 wounds with 41 3+/3+/1/1 attacks and 4+ saves (all before buffs) easily made them among the most terrifying units on the table.
The Trog didn't last more than the first turn as it got trounced by multiple units (including a maw-krusha), but in that single combat round it had been the focus of many more points than it had any right to attract, and even debuffed two of the three units that charged it with Noxious Roar. At the very least, it provided enough support as a 280pt monster-mounted wizard to be a reasonably effective distraction carnifex.
The Ark of Sotek was middling at best, really, which isn't surprising when its main attraction is 20 4+/5+/-/1 attacks with mortals on crits (3 mortals and 2-3 regular wounds is its average output, not including the d3 mortal wounds it can inflict on up to 3 enemy units within 9" *before it even fights*). A good tar pit all the same with its 2+ save, but you'd get a lot more use out of it with the Thunderquake Starhost battle formation and maybe the Itzl asterism (I went with Sotek as my first one in that game). Even then though, if you can spare an additional 20pts, you're probably better off taking a Solar Engine instead.
Beyond that, the rest of the army didn't really get much action to make a good judgement call on the units. Kroxigors didn't even get to see their time in the sun, as did the Saurus Oldblood on foot who spent the entire game running to keep up with other units. Even the Hunters didn't get to see much action beyond seizing a battle tactic objective and applying a -1 to wound debuff on a unit of ragers.
