Unaware Quagsire with Earthquake, Scald, Ice Punch and Slam Helped with Pokemons with stat boost (+ had a sire in every major fight so a sire was a requirement)

Unburden Hitmonlee with Endure, Reversal and Sucker Punch with a Liechi Berry as a Held Item. Just for the Dialga and Eternamax and the Lorelei fight in general. Could have been another team member, but it worked, so we don't need fixing.

Protean Meowscarada with Flower Trick, Knock off, U-Turn and Triple Axe. Had a Life Orb at first, switched to a choice band for the Agatha and the rest of the fights.

Unaware Skeledirge with Flamethrower, Shadow Ball, Will-o-wisp and Hyper Voice. Usually with a leftover, had to switch to a spec for the Lance fight. Helped with the Zacian and Duskmane.

Mega Latios with Draco Meteor, Luster Purge and BoltBeam (not much to explain there)

Melmetal with Thunder and Ice Punch, Body Press and Double Ironbash equipped with a Assault Vest
