G-slowbro gets a few options. I’ve been using
Modest, 252HP, 252SpA, Quick draw Quick claw
Shell Side Arm
But that’s because I’m using Porygon to set trick room, so if you want to use as a trick room setter you could remove slack off and go min speed. I’m still not sold on the quick draw + quick claw combo, so it may be better to do life orb/berry/black sludge for the item.
You can also add a third move for coverage. Shadow ball, flamethrower/fire blast, hydro pump, ice beam/blizzard, and focus blast all seem viable depending on the rest of your team
