But honestly, if I'm only able to win through the Perish Song thing or miraculous RNG, then it defeats the purpose of bragging rights. Oh well, one more try and then I take Dragon Rushes to the face like a winner.
Okay, so after focusing on buffing myself instead of debuffing Garchomp, I just got Aromatisse to Moonblast it a lot while Garchomp kept trying to Earthquake a mon floating on an Air Balloon. Victory is fairy-scented.
