U teach them how to fight u know that right ? that could be something very fun to do. U can team up with 3 amiibos against 4 cpus in 8 player smash or make ur amiibo face ur friends' amiibo. U can even team up with ur amiibos against ur friends which I cant do to wait.
That's why I said they'd be better than Lv.9s. You can already team up with computers aswell as real people without paying $13.
EDIT: Oh, and to team up with 3 Amiibos would be $36. Yeah, think I'll stick with regular computers.
