I saw someone suggesting knocking out the level 71 requirement of 200 super effective charged moves by getting a friend to battle and tanking the fight while you wail on them. This can work fine, but I don't have friends, so I figured I'd share my method of finishing off this challenge ina way that will help you work your way towards another Platinum medal, since we'll need 50 to reach rank 80.
It's a simple method: I take my UL Swampert, armed with mud slap and hydro cannon, to fight Ultra Candala. I build up and fire off as many Hydro Cannons as I can, if you don't charge them, you can fit quite a lot of them into one match. In 11 matches, I managed 56 charged attacks, and thats before working out a rhythm, otherwise it would likely have been well into the 60s. This method has the benefit of working on a Plat (if you don't already have it), can be done solo and can be repeated as many times as your sanity will allow.
While I haven't tried other trainer battles since hitting level 71, I have tried them in the past to see which could help me work on the platinum medal the fastest. Swampert vs Ultra Candala has been the most efficient combo I've come across so far, but if anyone has a faster way, I'd appreciate the pointer.
And to cover my bases: I'm not trying to pretend I came up with something new, I'm sure this has been done by plenty of people, and I'm sure it's been suggested in this sub before. I just haven't seen it myself and thought I'd share.
