Dobie, Wolfgang and Fang are my favourites. Fang is the only card I'm missing but I'd love to have him back again. I had him for almost a year before deciding to try new villagers with the update and I really miss him
Fang - I like his design best, and it doesn't hurt that he's been suggesting to play hide-and-seek every other day.
Wolfgang and Chief have nicer house exteriors though imo
I'd have to choose Fang, I had him in my campsite once but my town is currently full so I might consider him when/if I decide to swap out a dreamie for another villager.
