Strategy:

Spoiler

As you can see all the Pokémon here are slow, but the key first to win is using "Trick Room" and i have the advantage after that.

How almost many of the times i start the battle:

Aromatisse - Musharna - Audino

Audino uses SImple Beam on Musharna, then after Musharna suffers damage, in the same round Aromatisse uses Heal Pulse on Musharna then Musharna uses Trick Room.

2nd Round:
Musharna uses Calm Mind(Since now Musharna ability is Simple, its stats will increase the double) then Aromatisse uses Aromatic Mist to increase even more Musharna Sp.Defense and Audino uses Amnesia.

3rd Round:
After increasing stats Musharna is ready to attack, if there's a lot of Pokémon weak to fairy moves use Dazzling Gleam.
Aromatisse uses Psychic or Moonblast depending on the enemy while Audino uses Wish to keep enduring damage.

And that's how i mostly win the battles(i have win many battles with this strategy).

So what do you think of my team?
