I think amiibo concept is fine, it is just badly implemented.
Four amiibo should be enough to unlock everything; nothing more, nothing less.
Made a thread about it two months ago: http://gamrconnect.vgchartz.com/thread.php?id=213370
Things started going bad when the Toad amiibo was released,
releasing new amiibo to lock features on it is not good Ninty.
