I do love Unova for it's epic story and many interesting characters, introducing a lot of great items, moves and mechanics like unlimited tms, eviolite, hidden abilities end the shiny charm. It's got cool facilities, things to do and places to explore like the battle tree, nature preserve, join and avenue and pokestar studios. The music is lit. It's got some great Pokemon too like the Tao Trio, Hydreigon and Volcarona. I just don't think the Trubbish line is one of them though. I'm not trying to hate on this region, I'm just not seeing it with this particular Pokemon.
