I have gotten him down to his clefable once, but most of the time one of his pokes will sweep the rest of my team. And the Porygon's coverage is so hard on my team
Currently, the best luck I've had is with this loadout:
Togedamaru - Nuzzle + Zingzap, quickclaw to nuzzle the lead before it flinches me, can also OHKO the swellow but it often dies to something else
Empoleon - honestly the weakest link rn
Mr Mime - Dual screens, psychic
Arcanine - just a heavy hitter, helps with the Bewear
Mawile - Kinda neither here nor there
Primeape - can kill Porygon if it low-rolls Psychic
I've levelled up around 6 or so pokes at this point to try to get a new team, tried Avalugg against the lead and it works pretty well but it just gets OHKO'd by the Porygon immediately after.
What Pokes helped you beat him? Where can I find them? I wanted to try Aron but I can't find it.
