I've heard rumors that Amiibo data will be erased when you transfer it to Smash Bros Ultimate from Smash Bros WiiU/3DS. And I don't want to lose the training of my Megaman at level 50 and Lucina at level 28. But here in Venezuela they do not sell phones with NFC or NFC adapters, and bringing those devices from abroad costs more than 100 dollars for shipping. The NFC devices I have are the Wii U Gamepad, the Right Joy-con and the Switch Pro Controller.
