Hello, so I mess up evolving Clefairy into Clefable. I thought that if you evolve Clefairy you can still relearn Moonblast because of the move relearner..,,,,However, I was wrong and my Clefable is pretty much useless... Is there any way I can get Clefable Moonblast? Thank you so much if I can...if not alrighty...
