I trained three Amiibo to lv. 50 last night:
- Peach (codename "Ditzy," in white and red)
- DK (codename "Boosta," in pink, reference to "Jingle all the Way")
- Mario (codename "The Fonz," in black and white)
...and they all destroy me now. Like in a five-stock match, I'll get -one- KO before they beat me. And I haven't fed them anything.
In terms of training, I'd always start 1v1 using the same character as them. I'd use each special, nair, fair, bair, dair, uair, etc., several times each. I'd shield a lot, roll around, sidestep, air-dodge, grab, pummel and throw down, up, left and right.
In the second match, I'd use my main, ZSS, and go all-out against them. In subsequent matches, I'd use common speedy/power characters like Little Mac and Greninja.
Along the way, I'd mix in a match with all items on High, and make a point to pursue Smash Balls, etc.
As more amiibo were trained, I'd start mixing them into the training sessions from about lv. 30 onwards.
It feels so cool to have your own personal CPU opponent/partner that's stored in the figure. I really love this feature. I just don't know how to get loot from these guys.
