So I'm new to OU and was wondering what makes Clefable so good. On paper, it seems pretty bad with 95 / 73 / 90 defenses. Sure it can run calm mind and get a free life orb boost thanks to magic guard and it's immune to toxic, but does that really make up for its low stats? I guess it gets access to fire blast as a niche over other fairies, but they have better stats than Clefable. Clefable is also pretty ineffective against Mega Metagross, Magnezone, Mega Venasaur, most fire types, and is completely walled by Heatran. I can see that it definitely has a niche in OU but why does that niche warrant an A+ rank?
