Look, P-coach, I see your concern for the meta, but I have this handled, ok? Plenty of priority moves will be given out and volt switch, u-turn, etc will be spread among their respective types too, I will also handle the learnsets personally since you did the Pokedex stuff and banlists, which I will fix for non-changed pokes, making them banned as well.
I have another BST meta I came up with. Not sure on the name though, it aims to make the metagame more dynamic by buffing each pokes strongest stats (Equal Stat Pokes get buffs of smaller proportions to all stats).
For example, Arceus gets 122s across the board, Mew gets 103s, but then Scizor gets: 70/150/120/55/100/65, which is epic, IMO
