Name: Reliable Status Inficter
Analysis: The Pokemon games possess many different status inflicting moves, from Thunder Wave to Toxic, Hypnosis to Will-O-Wisp. There are very few Pokemon which have access to a wide variety of status inflincting moves, and even fewer who can pull it off successfully. Most status moves suffer from a lack of reliability: 75 is a normal stat for a status inflicting move not named Thunder Wave or Confuse Ray.
However, there are several abilities which help boost accuracy or increase the chance of a move's secondary effect activating. For example: Compoundeyes. This ability raises all of the Pokemon's attack accuracy by 30%, which eliminates the unreliable accuracy troubles of moves like Sleep Powder and Will-O-Wisp. No Guard also stands out, raising the accuracy of all moves to 100%. Serene grace would be an interesting addition if we wanted this CAP to go a more offensive route.
With a good speed stat and a reasonable amount of defense, the Reliable Status Inflicter would have no problem outrunning and crippling a Physical sweeper with a burn, or prevent a wall from setting up. In theory, a reliable status inflicter could plug your team's weak spots.
Extra: I'm pretty sure there's no other Pokemon which fills this role successfully. I've seen dual status sets on plenty of UU and NU sets, but I'm not sure how well they work, if it all. It's a cool idea, I think, and has interesting potential in the competitive scene.
Balancing it could be tricky. Would super-fast status moves be broken?
Would increased accuracy on a Pokemon with strong offensive stats be too good?
Would a Pokemon like this even be useful, or just an interesting novelty?
