Second Super Smash Bros. Finally this year's event, Nintendo is hosting an amiibo tag contest. It will start later this week on January 10 and will continue for three days.
Although it may seem like a normal time, this limited-time event is actually different from normal, since your friend is required to participate. And to be competitive, you'll have to use FP (player player) from your amiibo. There is no interaction with the other players at this event, either.
In related news, the latest Smash Bros. update recently added support for Dark Samus and Richter amiibo. Will be participating in this week's Smash Bros. event. Leave a comment below.
