How do amiibos learn?

[Kirby Phelps (PK)]

So......I've noticed something a little weird. I've been training my Little Mac amiibo in one-on-ones using my own Little Mac and Ness. Back when it was around Lv. 30ish and I'd continuously kick its ass, I'd taunt every time I took a stock from him. Eventually, when he managed to KO me, he started taunting too. It was pretty cool seeing how he learned to taunt from me. But now my Little Mac's at Lv. 47, he's gotten a LOT better and actually wins a good amount of matches. But, I've noticed that he stopped taunting. Why? I still remember to taunt all the time when I KO him, has he just gotten too mature for that stuff?
Also, can amiibos learn anymore past Lv. 50? I know they can't level up, but can they still learn new tactics?

Beats me. There's much mystical stuff surrounding amiibo. All I know is that I should probably stay away from amiibo at all costs, or I'd abuse their ai (such as playing against a MM amiibo but then just going Lega, only stopping to recover).

I found an interesting post on the Smash Bros. subreddit with some information on how Amiibo's work:
