These don't work for me, I'm using Arduino Uno, if you are too I advise staying away from these, bricked a few tags before i figured it out

ParadoxalDream - I've only tested mine with TagMo. Sorry about that.

Those bin files don't work with the N2 USB Manager program, they're only 532 bytes and they should be 540 or 572 bytes.
I've downloaded the ones JustADad uploaded after you (which are 540 bytes) and they work fine, even if N2 has yet to update their program to officially support those amiibos.

Card art has now been added ^u^

yes... can you please share the champions card art too?
thank you very much
