>>33225048It can only 2HKO if it has Charti Berry. Otherwise, it's a OHKO. Still, you could achieve that with just about any Rock type. I mean, fuck:
196+ Atk Geodude Rock Throw vs. 0 HP / 0 Def Volcarona: 352-420 (113.1 - 135%) -- guaranteed OHKO
I'd personally use Mega Aerodactyl instead of Lycanroc, though.
