Thanks. I became a mod last month.
There are a couple of guides out there you can use. Blade has been working on a guide herself. (Link)
There are also a few videos you can watch.
Standard abuse for Legends & Wild Pokémon Part 1
Standard abuse for Legends & Wild Pokémon Part 2 (Natures, ability, shininess)
Standard abuse for Bred Pokémon
If yo have any questions feel free to ask me.
