Forcing to use poliweath just for bb gren? Tangrowth and gastrodon get 2hko by ash gren. Mantine doesnt like switching in and out too much cuz of stealth rocks and gren can just pit on spikes on ur switch in.
that's why i said that only mach punch is able to take down gren. the vacumn wave is counted but it's way too rare to see spatk lucario on h.o, and look ex speed 2hko sucker punch 3hko while 1 hydro pump can easily take them down
I know the others have already talked about this but. Literally the only priority that can potentially kill ash gren is breloom's mach punch. Gren is just laughing on all other ones
