I have a Wii U but I haven't set mine up since my Brother has his one set up in our room.
We have all the Amiibo's from Wave 1 & 2, so mine are sitting here like figures, I can't complain.
But it does really effect what you're thinking of doing with them, otherwise we're just collecting them :>
I'd collect them. but if I did, I'd probably just leave them in their package so they wouldn't be used. If I do though, I might do that trick that involves slitting the bottom open a bit or something.
