I had a gible wondertraded to me just before I got to Charlotte and gachomp’s been a valuable asset to my team ever since. Outrage literally destroys opponents, especially coupled with choice band. Iron head also made it so that she could deal a great amount of damage against fairies, which was especially useful against Adrienn. Things just got even better once I had access to stomping tantrum, a reliable ground stab. There were some gym battles that I definitely wouldn’t have won without her, such as Titania.
