I've got a living spirit collection- I've got at least two of everything, except for the ones you need to combine for and the partner pokemon, as they've only shown up in the shop once.Whew, finally have a complete list of spirits (for now, anyway). All 1,300+ of them. Now I wonder if I'll ever be autistic enough to try to go for a living spirit collection, kind of like how some Pokémon players aim for a living Pokédex.
Spirit hunting is surprisingly easier to do than trophy/sticker hunting was back in the day.
Except for the same spirit I've been missing this whole time which STILL WON'T TURN UP.
