Klefki

Klefki is the primary Trick Room setter and status enabler for the team. Prankster gives all non-attacking moves +1 priority, making Thunder Wave near-guaranteed to land and Rain Dance an instant weather answer to opposing rain teams. Bold nature with max HP and balanced physical and special defense investment keeps Klefki alive long enough to do its job. Shuca Berry covers the Ground weakness so opposing Earthquake users cannot easily pick it off. Thunder Wave synergizes directly with Mega Feraligatr's Facade and Basculegion's Hex, making Klefki the engine that activates both sweepers.
