>>16261525>gengar got very low physical defense which means one brave bird from my crobat and it's done>252 Atk Crobat Brave Bird vs. 0 HP / 0 Def Mega Gengar: 184-217 (70.4 - 83.1%)>252 SpA Mega Gengar Shadow Ball vs. 0 HP / 0 SpD Crobat: 193-228 (62 - 73.3%)And you're both at the same speed, so you have a 50% shot of killing it turn 2, assuming you haven't died due to recoil+his attack.
If you run any set besides Jolly+252 Speed, you get outsped every time and lose 100% of the time to max speed Gengar.
This is all assuming he doesn't just destiny bond turn 1 and take you out with no effort, already doing his job and losing you a crobat.
Tons of broken things can be killed. That doesn't matter when its job is to kill you, and if you die trying to kill it, it's successfully done its job, it doesn't need to be alive anymore.
