I got through gyms 8-16 with wobbuffett and sharpedo destiny bonding everything. I set up trick room on bronzong, let it die, then counter/mirror coat would take out one or two, then destiny bond would take out another. Once trick room faded sharpedo took over as another sacrificial KO.
I finished episode 17 with a team of level 70s using these filthy strats. Though admittedly an 8 turn long freeze while I set up against amaria helped.
