I cant remember the list exactly but it was something like
2 big meks with
SAG each in his own bastion,
2 squads of lootas in battlewagons,
the rest was spammed 20 shootaboys in wagons with as many big shootas as possible!
All wagons had 4 big shootas i think.
Sooo much firepower! and against assault armies when they try and assault your wagons you get another free round of shooting!
As for now I run an Badmoons Deffwing
4 mega warboss
4 mobs of 6 meganobz
4 battlewagons with 4 big shootas each
this is surprisingly competitive untill your opponent starts spamming vendettas
Im thinking about dropping 1 boss, squad and wagon which will allow mw to add 2 squads of fire warriors 3 suicide crisis suits and a commander with 3 broadsides,
not really to combat fliers but more so i can play tactically and wait a turn then counter charge
