I have 30 tags for sale. I'll sell you 5 tags for 20$ CDN and I will send them by regular mail. I will only send them within Canada. They are 18 mm round stickers with a white back, no logos on them. They work fine for amiibos. I have made 15 amiibos for BOTW which I'm using on wiiu. I'm using the latest Tagmo app, it couldn't be simpler to flash a tag. I made a total of 16 tags , but one failed for some reason, it was a spoofed Link. Since amiibos require to be locked , it is not possible to erase this tag anymore. Not sure if it was the tag , tagmo or my manipulation that killed the tag. My friend flashed 10 without hassles. So 1 out of 26 failed. I did manage to get the deity armor set, you can only scan the tag once a day but you can reload your save as often as you want in order to get the item you really want from the chest. I've gotten most of the exclusive gear, missing a piece or two, but too lazy to keep reloading until I get all the gear I want. I'll probably finish it over the week-end.
I am in the greater Montreal region (south shore) in Québec, if anyone wants to meet instead of mail shipping. Otherwise you can pay with paypal.
I made a few cards using the amiibo cards images from the forum here. PM me if interested
The only way for Nintendo to ban you using unreleased amiibo spoofs would be to read your saves at a distance , or that within BOTW itself it would report unreleased amiibos used.. but that would be a long shot in both cases IMO.
