Rotation takes place before an action. Also, in case you didn't know, you get to make a law at the end of every round, and breaking that would cause whichever pokemon to take a flat 10 damage.
I'll lead with Deino@Exp. Share. In the back are Archen@nothing and Golett@Lucky Egg.
[Enable Hustle] Crunch ~ Bite ~ Crunch
If Minimize and not taunted, then Roar that action.
If Will-O-Wisp, then [Rotate Golett] Magic Coat that action, and [Rotate Deino] [Hustle Enable] Crunch ~ Bite afterwards.
