Klefki currently resides in the Borderline (BL) tier of competitive battling, meaning that it is banned from the Underused (UU) tier but not used enough to be a part of the Overused (OU) tier. Klefki has an amazing Steel/Fairy typing that allow it to check many omnipresent threats, such as Latios, Weavile, and Mega Gardevoir. Klefki's ability Prankster can be utilized to its full potential due to an array of great supporting moves, such as Spikes, Thunder Wave, Reflect, and Light Screen. Prankster Thunder Wave is especially notable because it can allow Klefki to slow down most set-up sweepers and effectively stop them from tearing a team apart. Klefki's downfall is its relatively underwhelming stats that give it little offensive prowess, but it is regardless an amazing support Pokemon in OU.
Klefki is also a very viable support Pokemon in the Ubers metagame. Most of what makes Klefki great in OverUsed translates to the Ubers metagame as well, as its typing allows it to check top-tier threats such as Darkrai, Xerneas, Latias, Latios, and Yveltal. Prankster Thunder Wave is huge in a metagame like Ubers where set-up sweepers like Geomancy Xerneas and Mega Salamence could easily sweep through teams if given the right support. Klefki's access to Spikes allows it to rack up hazards, while it can use Toxic on Defog Arceus forms to wear them down. However, Klefki has no reliable recovery and is shut down by Primal Groudon, the biggest threat in the Ubers metagame. Despite this, it remains one of the most effective support Pokemon in the Ubers metagame.
