Just watched the twitch stream, looks cool! Shame the demo is only for 3 1 hour slots on only certain days......
EDIT: and I'm going to miss out on 20 challenges and high end "gear" by not unboxing my amiibos..... damn it.
1) Buy some more
2) Use them
3) Sell them for a profit.
4) Keep your boxed Amiibos boxed.
