>>47273702If you ever want to get into 6v6 competitive, Pokeaim is the best channel for that. It used to be shofu back in the day (he's the one who got me into competitive), but he's kind of sort of retired with Pokeaim now being the best source.
For VGC, Wolfey is a former world champ and CybertronProductions (Aaron Zheng) who made top cut in Worlds multiple times are the best sources you could ask for.
For non-competitive, it's hard to say, but it's worth noting that some of the above have done in-game runs/nuzlockes you may find interesting to follow given they're from a competitive player's angle.
