Lucario? I get that its metal claw can take out fairy types (Tapus, Mimikyu) And fightings nice to have for electric types. You would HAVE to get the Trick room up and make lucario 0iv in speed. It does not want to take a Tbolt/Discharge from fast pokemon like Tapu Koko, Raichu and Xerkitree (usally running choice something to make it faster)
