What do you think is canonically the most dangerous environment for a trainer?
My vote goes for deserts:
>Flygon and Hippowdon constantly spawning sandstorms because they're assholes
>trip and fall into a pit
>Trapinch rips your leg like it's paper mache
>get in range of a Vibrava hunting
>faint and die to the scorching sun
>literal sand sharks exist in this universe
And the best part
>can never, ever get some rest or sleep at night
>the Cacturne are coming
