Look, if I know anything about NFC, it is that unless the amiibo tags are NFC locked (meaning they cant be read or written to by a regular device), you should just be able to rip the NFC code off of the amiibos using a cheap android phone or a cheap NFC reader off ebay and post them so other people can download them and write them to NFC tags you can buy for like $10 on amazon and then just use those instaid of buying amiibos (alot cheaper). Let me know if it is possible or if I am completely wrong!
