>>30913714maybe not existed before Arceus, but some of it seems like a bit of the Ultra-beasts mixed with Girantina.
I mean, if we didn't already have those, I'd like to see it, and in a way it makes me annoyed they sort of broke up the concept than bundled it together.
>>30913849As someone whose main Pokemon experience draws from Gens 1 to 3, the funny thing I find with Island trials is that it's often still similar, in many ways, to the various puzzles which fill many gyms, especially towards the late games.
But that's just my perspective.
I do like your suggestion of gyms who break up the monotyping, though my own suggestion would have been for Gym Leaders or whoever replaces them would be MOSTLY monotype but keep one to two pokemon completely and wildly outside their standard typing, sort of meant to goose players with something unexpected and force them to change up their strategies after they've gotten comfy with having one or two pokemon ace through the rest of the Gym Leader's pokemon.
