GOKAAAAI... SILVER!
Funny thing about me beating Cynthia the other day; Weavile was still outsped by Garchomp and one-shotted by Flamethrower (despite Garchomp’s low Special Attack), but I had taught Porygon_Z Ice Beam with the TM specifically as a backup in case that happened, and I had the good fortune of Garchomp’s Dragon Rush missing, and Porygon_Z’s Ice Beam one-shotted the Garchomp. After Garchomp was taken out, the rest of the fight was much easier.
