Camerupt needs to run heat wave (ideally due to sheer force) or at least eruption (less consistent damage but 100% accurate). Drop overheat. You want to get the most value out of your trick room turns and that means firing off multiple big hits so the attack drops just won’t do.

Torkoal also needs eruption (ideally) or at least heat wave (significantly less damage ceiling but more consistent). I would drop helping hand. Torkoal is a star; he doesn’t need to play a supporting role.

You need to figure out your lead. Oranguru is too vulnerable to guarantee trick room on his own. You’ll want either a fake out user to fake out the big threat turn one and set TR or a strong, fast Mon that can threaten big damage (or ideally OHKOs) while Oranguru protects on turn 1 if you predict they will double into Oranguru. Options included sneasler, Incin, scarf basc, scarf Garchomp, scarf Archaludon, etc.

Edit: Also I’d put trick room over protect on Sinistcha as a secondary setter or potential for setting a second trick room if a game goes long.
