Hello friends!

I'm been following the forums for quite a while, staying in the shadows most of the time :O

But as I started to figure out, pokemon Isn't really just a catch your fav pokemons and use them for battles (atleast not for some people)
Well to get to the point, I started seening the interesting part of pokemon.
The "strategic" side, and I was wondering where you guys keep a track of all the pokemons? How did you learn what was the best moves for a pokemon?
Or what kind of pokemon is the best in the meta at the moment? or the nature for that matter?

I don't know if it's just me who's overthinking it too much, but I like to find out before it drives me crazy
