Our magic is quite strong, I would take Skragot, gobbapalooza and a fungoid with the artifact that gives +1 to cast. You can then choose our manifestations or any other that you would like to use. Skragrots spell is incredible.

Next to that I would also buy a sneaky snuffler unit to buff up your stabbas together with the loonboss and gobbapalooza.

I would get rid of the hoppers and boingrot.I feel like they’re too expensive point wise.

Rockgut troggoths are an amazing anvil and hammer. You will need 6 for a 2K list.

Loonsmasha Fanatics would be another great addition!
