In the Pokébase QnA section - Are we allowed to as moveset questions for unevolved Pokemon and Pokemon that do not fit in Singles battles that well, such as Mareanie? I read an article that was answered about 3 years ago, but I don't know if it has changed since. On a side note, apologies if this question has already been asked.
LC questions are fine, if you're looking for specific sets for a Pokemon. In fact we already have LC movesets for a ton of Pokemon, see the little-cup tag. But there's no requirement for going through every Pokemon like the regular movests, they just get asked as/when needed.
Please don't ask too many right now though, since we're also going through the regular moveset questions for Sun/Moon.
In the past we did popular LC pokemon, but I say you should just post it on the final evolutions page. Having a question for all the LC pokemon would just be chaotic and its not that popular of a tier anyways.
