10 MORE Best Pokémon You Never Bothered Catching

Yes, we're talking about the Pokémon that's just a bunch of keys. It looks ridiculous and that might be why it remains in your PC.

If Whimsicott was the original Prankster, then Klefki is the one that probably best uses it. This sixth generation steel and fairy type Pokémon might not have a great HP base stat, but it's a defensive wall that can set up some horrific obstacles for your opponent to wade through.

The typical move set for Klefki revolves around laying entry hazards. Thunder Wave increases the chance of your opponent becoming fully paralysed, while stacking multiple uses of Spikes increases how much damage swapped in Pokémon takes.

It combines these two moves with either Dazzling Gleam or Play Rough, depending on whether your physical or special attack stat is higher. The final move can be either Toxic (to badly poison enemies), Foul Play (a dark type move that exploits an enemy Pokémon attack stat gains), or Magnet Rise (to levitate, making Klefki immune to ground type moves).

It may just look like a set of keys that you have lost in between the sofa cushions, but it's worth unlocking the PC, and taking Klefki out for a spin.
