>>54802743Perrin points out that Ursaluna is considered uncommon, and no particular fanfare is given to Hisuian Growlithe (in fact, it's implied they're still kicking in rural and religious places around Poke-Japan, considering there's komainu statues modeled after the line in Kitakami) or White-Striped Basculin. So generally speaking it's safe to say they're all uncommon at best, rare at worst.
Another example courtesy of SV's Pokedex is that we DO know for a fact however that Wyrdeer is extremely rare, because the conditions a Stantler lives in need to be harsh enough to force it to draw out its full potential, learn Psyshield Bash and master the Agile Style of battle and thus be eligible to evolve, which is currently only possible in Hisui.
