Strategy for Insane Mode (Updated December 2020):
On Insane Mode Alice's team will permanently be affected by Tailwind and Strong Winds. You won't be able to out speed her Pokémon so faster frail Pokémon will not be very useful this fight.

Minior: Will typically start off with Stealth Rocks. If their HP is high on turn 2 they will Shell Smash, otherwise they will likely use Acrobatics. Very easily dealt with by any steel-type boosting their attack on turn one, then oneshotting it on turn two. The best Pokémon for this is Mawile.

Dodrio: Will likely OHKO any Pokémon that does not resist it. A really easy way to deal with it is to switch in a Fighting-weak Pokémon after knocking out Minior, then immediately switching into a ghost type. Spam a status move while Dodrio knocks itself out due to Jump Kick recoil. This is because Alice will sometimes switch in Pinsir before Dodrio dies.

Pinsir: Extremely fast and strong. Can one shot practically every Pokémon available at this point in the game. If you're really having trouble, recommend using the DexNav to catch a Shuppet in Grim Woods that will have Prankster upon evolving into Bannette. You can use this to deal with Dodrio, and then Wil O'Wisp Pinsir. Combining this with any Pokémon with Intimidate should secure an easy victory.

Gliscor: Any Special-Attacking Ice or Water type should easily defeat it one on one.

Staravia: If you can deal with Pinsir, you can deal with Staravia.
