>>42555583That is hardly a gimmick when the whole game is double battles, btw, this was also a "gimmick" in the Mosdeep city gym (At least there, the gym leaders and their pokémon had a design that also played on the theme) but in SwSh there is a gym where "THAT IS THE GIMMICK, WOAH, LIKE.... 5 GENS AFTER IT WAS INTRODUCED", don´t even remember which gym it was, what a letdown of a fucking game.
But yeah, OP, I am open to more gym ideas like the Battle Frontier rules, would be much more interesting, even more if the levels of your pokémon were fixed when doing the challenge.
