I personally don't know how to feel about Klefki. A part of me just wants to forget Klefki exists because of a juvenile design and all around bad stats. But another part of me wants to have Klefki on a lot of teams because of a great typing, and priority hazards. In fact, a suicide lead with priority Spikes seems to be it's best, if not one of it's only movesets. It can be a good Pokemon for what it's worth, but it certainly won't be replacing Ferrothorn for setting up hazards, or Whimsicott for utility on my teams. Just my opinions though.
