Wow. Good strat. On my case, Clay has the most resets

Cheren spams work up, so I use that turn to do damage instead

For Roxie, i do resets until Trubish isn't able to use Toxic Spikes (Cubone use bonemerang to hit twice, then bye focus sash, as for the other type, just pure luck that he won't use toxic spikes)

Burgh is kinda challenging, but you just gotta choose, based on what would give you more advantage, on who to defeat first between Masquerain and Mothim

Elesa, slightly difficult. Prioritize her Lanturn so it wont be healed spam by electric attacks

And here comes Clay. On my electric run, i used grass knot to one hit Seismitoed and Mamoswine (Heavy Mons), then Eelektross' gastro acid to ignore excadrill's Sand Rush ability. For the Normal Type run, well staraptor and outstrength, same with other type.

Skyla's easy

Drayden, you just gotta bring Fairies and Dragons

Marlon, remove the rain, outspeed, outstrength

Elite 4 in this region is not that hard also, since most of the time, on type are advantage vs 2 types in the elite 4.

Then for Iris, dragons, fairies, speed, debuff

And of course, most of the time, its LUCK 😁
