simple to get over this amiibo - if you don't like DLC/micro transactions and figurine toys, don't buy it. it is DLC on a toy and that is how Nintendo wanted to market it. a design done by Nintendo and the cretors of Skylanders, and others.
while other publishers have its own way of DLC, it is basically similar.
the plus is you'll have a toy, if you don't like it then just don't buy it.
don't support DLC/micro transactions as well.
