Several years ago, after the debut of Animal Crossing: Happy Home Designer, Nintendo released amiibo cards featuring the extensive list of Animal Crossing characters. At the time, reception was pretty mixed. The cards’ primary use was to invite specific villagers to Happy Home Designer to decorate a home for them.
Later, Animal Crossing: New Leaf was updated with amiibo support, allowing RV-riding villagers into your town. Nintendo eventually released four different series of amiibo cards, featuring hundreds of villagers. Outside of those two games, the cards also worked with Animal Crossing: amiibo Festival, which few people played. For many years, you could pick up a pack of cards on Amazon or eBay for relatively cheap. But now that we’re all playing Animal Crossing: New Horizons, they’re are making a comeback in a big way.
