How can I build an effective 1k orcs and goblins list for 8th edition?

I'm mostly interested in night goblins, black orcs, and mangler squigs.

I currently have access two doom diver catapults and some spear chuckas but no other artillery. I dont really care to buy a stone lobba or whatever, but can if the army is unplayable without it.

so far I'm looking at
2 doom divers
1 mangler squig
lv2 night goblin shaman
lv4 night goblin great shaman
7x5 night goblins (spears) with all the shit
5x4 archers with just fanatics
the rest of the points spent on black orcs

What units are a waste of time in this edition? normal orc boys and normal goblins?

how are boar boys?

generally how do i deploy this army? I figure black orcs in the middle, one doom diver and unit of night goblins on each side. not entirely sure where to put the squig and wizards.

thanks!
