Bluebear and Zucker were in my first town, Stardust, and I loved them to death but their houses were in bad spots. So I moved them to my second town, Valhalla. I was planning on moving them back in later when I could buut I'm really impatient so I might just wind up using their amiibo cards. Lucky though, I did manage to get Bluebear's pic before she left.
I usually only move villagers from one town to another if I'm planning to delete a town but I'm really sentimental about particular villagers and I don't want to adopt them "fresh" from someone else. Except for one case, where I moved hamphrey from Pyrena to Luferna because his house ended up in a dumb place...
None, I only have one active town that I use and the other is to store my villagers that I need to move into my current town at some point. I can't handle multiple towns as it is, so transferring villagers to live in another would probably give me a headache. Even if I did have the patience for it, moving out villagers takes a lot of time and effort if you don't have amiibo cards.
