It's part Fairy and part Steel, which can be quite useful to cover its Fairy weaknesses...though adding a weakness to Fire and Ground.
Stat-wise, its HP is low, but the other stats are decent I guess. Its move-pool is quite restricted, but I actually don't mind that too much.
I'd really like to have a Fairy type...I'm fully aware about other good Fairy types such as Sylveon, Gardevoir and others, but I really like Klefki, personally.
Should I add him to my team?
