Conk is prediction reliant and slow- every time you manage to mitigate the effect of an attack with a switch or just clicking protect, conk burns a little closer to death and possibly into range of being killed in one hit by a faster mon (as long as mach punch doesnt kill it of course). Sometimes you can switch in something that hits conk supereffectively so long as you read what button he's pressing and force him out thanks to his low speed.What beats conk. I legit can't stop this monster and now that it has knock off I am extra terrified.
Or, dont let them deploy conk in the first place. It doesnt have too many switch ins cuz its slow as fuck. It is pretty reliant on slow volt/turn, sacking, doubles, going in on a passive mons, or going into attacks it resists.
