Amiibo have been used for many things over the years, from levelling up fighters to summoning meat rain, but WarioWare Gold is up there for the best Amiibo interaction yet invented.
As per Mon Amiibo, WarioWare Gold allows you to plonk three Amiibo down per day, earning you a varying number of coins to use in the in-ghame capsule machine. But there’s another benefit – Wario will “sketch” you a picture of whichever character’s Amiibo you used. He seems… untalented.
