Klefki @ Leftovers
Ability: Prankster
EVs: 252 HP / 4 Def / 252 SpD
Careful Nature
- Spikes
- Thunder Wave
- Magnet Rise
- Play Rough
This team has lots of fast mons, but outside of that lacks speed control for scarfers and dragon dancers. Scizor has bullet punch but it isn't very powerful without investment or swords dance. Klefki's priority thunder wave cripples dragon dancers before they get out of control such as charX, Altaria that threaten this team as well as random scarfers and faster mons such as megaZam, megaLop etc which can also wreak some havoc.
Priority spikes are also fantastic for this team due to the large number of switches that VoltTurn causes, racking up significant damage to net easy late-game KOs with bullet punch.
Play rough is chosen over foul play as the team already has pursuit and knock off but other than Raikou's HP ice has no way to deal with dragons.
Finally, magnet rise to take advantage of ground types who resist thunder wave to allow klefki to set up more layers of spikes.
Klefki also offers decent defensive synergy with this team, with many resistances, in particular grass for Starmie and Keldeo.
SpD investment was chosen because earthquake being the main physical attack that scares Klefki is neutered by magnet rise, and the team already has Lando as a physical tank.
