I just thought up of a funny strategy. In the scenario in which Scarfed Rotom-H with Trick is facing an Air Balloon Mold Breaker Excadrill, they'll think that they can get past you with Mold Breaker EQ, which is when you Trick them to receive their Air Balloon, protecting you from EQ since Mold Breaker only bypasses Abilities, while they are helplessly locked into EQ.
Or you could just outspeed and Overheat for the KO since you're scarfed.
