I run a 4 man squad on offense: Nute lead, Dooku, AV, NS Zombie. It has pretty niche use and banners aren't that great, so it's better in TW, where keeping prot doesn't matter, but with just one relic (R6 Dooku) it can deal with high relic BH squads on offense. Zombie ten down helps land the stuns and as long as Dooku and AV can crowd control the AOEs, the enemy is stuck hitting Zombie for most of the fight while Nute whittles them down with Extortion.
