I had to decide what to keep on and what to get rid of, and Clefable was one that I had to omit
I understand but Clefable is actually very, very good. If played right it's one of the biggest threats. Between it's ability to heal, cosmic power, Magic Guard, and how versatile it is, I'd easily put it among the top 5 fairies.
Before it's biggest weakness was fighting, but now it resists it. And sure BP Scizor can run it's course with it, but any half decent player won't let that happen. It also carries flamethrower/fire blast for the more skilled players who'll predict the switch.
