What team without Grievous should I farm and gear to unlock 7 star Padme in 1-2 months (next return)

Whoever you use, try to avoid using b1, dooku, sun fac, geosol, dooku and droideka (if zetad).

They all have out of turn attacks which will grant the enemy they hit 50% health as indispellable not removable protection up that may prevent all debuffs from landing.
