Do you still need the diglett?
Yep, I still need Diglett and Geodude. Both should be adamant natured, and be caught outside Pokemon Sun and Moon. Then you should be able to transfer them to Sun and Moon through Poke Bank.
The reason why I would ask for them to be adamant is because when you breed even two
kantonian Pokemon in Alola
without the everstone, the offspring will become an
alolan pokemon. (i.e. a fire vulpix plus a fire vulpix is a fire vulpix in gen 1 to 6, but is an ice vulpix in gen 7). If you use the
everstone in breeding, they will become a
kanto pokemon instead of an alolan pokemon, but the nature will always be passed down with no exceptions. I only have a mild golem and bashful dugtrio in their kantonian forms. I do not want an electric type geodude or a steel type diglett, and I can't get a pure ground diglett or a ground/rock geodude with the correct nature based on what I have now.
I do think Marowak, Raichu, Vulpix/Ninetales, and Sandshrew/Sandslash were better in their Alolan forms, but not Diglett/Dugtrio or Geodude/Graveler/Golem. I don't care about the rest.
