Weather Slayer
Momentum is way too broad, and we should keep CAP to more specific aspects of the game. A concept like Momentum is too broad, it's like having "Typing", or "Offense" as a concept. Momentum is an integral part of the metagame, and doesn't need an pokemon specifically dedicated to it in order to be important. However, anti-weather barely exists in the metagame and would be maybe the most interesting concept CAP has done in a while.
