New Master Trainer Details for Pokemon Let's Go!

Finally, some decent sounding post-game content for a Pokemon game. Basically, once you clear the main story, there will be "master trainers" across the entire region for you to face. There's a master trainer for each Pokemon in the game, and each master trainer is an expert at their Pokemon.

Personally, I think this is a great way to add some post-game content to Pokemon. Something a bit better than going fully autistic managing EVs and IVs.
