Camerupt is made for Trick Room, having huge offenses boosted further by Sheer Force, and one of the slowest base Speed on any viable pick at 20. Camerupt is not meant to be a lead, since its defenses are not especially great. Its best use is to come in after Trick Room is set up, then start dealing heavy damage. Priority blockers like Indeedee or Farigiraf are greatly appreciated, since Fake Out is a way to stall out Trick Room and slow down Camerupt. Rain teams give Camerupt a lot of problems, so having a way to change the weather or beat the water types will let Camerupt shine.
