This stage returns after being in the WiiU version of Smash 4. It’s based on the elite league arena from the Pokemon X/Y games. I vaguely remember the area in the games as it’s been quite a number of years now.
I like how the stage changes and implements something from every (or almost) type of pokemon.
And it’s not just cosmetic either, many stage hazards will pop up now and then. So you should be careful.
While far from my favorite stage of all time, it’s one of the better ones from the WiiU era.
