You can only get Pumpkaboo line via Pokebank transfer and Inkay was only a thing in USUM nativly. In SUMO, you needed to transfer it.Wobbuffet can be pretty damn OP though, when the writers care enough that is... it's an on-off thing
It sure was interesting when both TRio members had more than one battle Pokemon though... now that they only have one a piece, it actually does feel repetitive when they attack. Especially when it came to Inkay, who never changed or gained new moves :/
If Mareanie really does evolve here, I think that's basically proof enough that the TRio Pokemon are staying for Galar. Mimikyu's popular, and they don't seem to be making effort at giving closure to it's Pikachu hatred... it'd be better if they stayed, so so much better....
I'm still baffled as to why Gourgeist and Inkay couldn't stay, their species literally live in Alola. And the two could have benefited greatly from staying, especially Inkay. Darknium for James would have made a heck of a lot more sense then... come to think of it, James needs to win so we can see him pull off the Dark z-move on the next round. Poor guy's barely gotten to use it compared to Jessie
