Ok, so I got my first game of AOS 2 in with the Ironjawz, list was:
Realm = Hyush (which I think is amazing just for Aethrquartz Brooch)
Megaboss on Mawkrusha (Mirrored cuirass)
Warchanter (boss Stika)
Wierdnob (Aetherquartz Brooch)
10 brutes
5 brutes
5 brutes
10 ardboyz (opponent allowed 20 points extra to get these in as my 2nd 3 gore gruntas not painted)
3 gore gruntas
ironfist
blood toofs
cogs
I was against sylvaneth
Treelord
Durthu
Drycha
3 units of 3 x kurnoth hunters
2 units of spite revenants
1 unit of dryads
The stacking of command abilities and movement buffs was decisive in this, I did the 1 drop and gave first turn to my opponent who blocked off the center with wildwoods around deadly terrain and then move his army into the woods to occupy them thinking he would only be in range of a possible turn 2 charge with durthu being 18" from the closest unit.
Of course cogs was cast, and then I successfully destruction moved 2 units of brutes forward followed by rolls of 4 or more on both units of brutes for the ironfist and before the movement phase had even began I had closed that gap to 8", giving me movement to skirt the nasty trees with my 10 brutes, and my 5 brutes simply waded through a forest taking a casualty to slam into a unit of kurnoth hunters. On the flank my gore gruntas tore across the table towards a little unit of spite revenants on an objective.
The charge phase was big, 10 brutes into durthu (the picture below is the hole left by durthus demise) - 2 units of 5 brutes into the kurnoth hunters on the right, and surprised my opponent with a big charge from my mawkrusha which sailed over durthus head into drycha.
The waagh was most brutal, 3 waaghs done in one turn, 2 of which were 6's giving +5 attacks per weapon to my guys. I even recovered a command point on a 5+ allowing me to finish my turn with another in the bank.
With smashing and bashing and the +5 attacks it was a slaughter, durthu, drycha and the kurnoth hunters on the right were slaughtered before striking, and on the left barely in camera shot the gruntas killed the revenants.
The sylvaneth responded in their turn by sending 1 units of kurnoth hunters into the warchanter and slaying him, and sending another unit plus the treelord into the 10 brutes, killing 5 of them but the treelord taking 3-4 wounds in the process.
In the Ironjawz turn 2 it was mop up. Movement shenanigans put the remaining 5 man brute units into a kurnoth hunter unit and the dryads, the megaboss went into the last kurnoth hunter unit and I left the 5 remaining brutes from the 10 man unit to fight the treelord with some waagh support.
Again - 5 additional attacks from Waagh. Used 2 Waaghs and got +2 attacks on a 6 and +1 and recovered another command point I used for a 3rd waagh which gave a +2 attacks. Everything died horribly without striking back.
Ironjawz total victory!
A lot based on luck for command abilities and movement so not representative. 4 of my 6 command rolls were 6s which is a bit stupid, but even if I had no 6s I think +3 attacks would have done the job. Ironjawz are even more lopsided than they used to be - in your turn they can do an almighty crushing alpha strike that sweeps the table of those in contact, and all your buffs and abilities expire for your opponents turn and they become fragile things that fight like wet noodles, only to explode again in the next Ironjawz turn.
I liked the list - the hyush artifacts are really good for us. I dont like the glaring weakness in the army that if the mawkrusha dies the army loses all effectiveness.
