So, the idea is the Mek guns +Big mek with hang back to provide heavy firepower threat while the kult moves into position. The Grot squads do the normal back point holding to generate extra CP.

The Wartrike to leads one of the full warbiker squads as the warlord and with the Wazblasta to add to the firepower of the squad, while the other bike squads and deffkopta squads follow to the front line for the waaagh call.

The Warlord with "faster than youz" will lead a 20 squad in the Battlewagon, allowing them to disembark and charge after the Battlewagon moved. This will let them get into combat as fast as the bikes or koptas. The Battlewagon then is just a mobile shooting platform with a deffrolla.

The warlord and weirdboy will lead the other 20 squad to let them jump in when it's combat time. Depending on the flow of the game, they could jump early and hit a small squad that is on its own, something like how we use our gretchin, or as I was envisioning the way my buddy uses his chaos cultists.
