How To Defeat Cher In Cup Rematch?

After completing the Main Story, you can rematch the Champion Cup as many times as you would like. This time around, you can select which opponents will be added to the tournament or if you would prefer a random set of foes. There are twenty-six trainers you can face this time around, including Hop, Leon, Marnie, the eight Gym Leaders, and fifteen Random Pokemon Trainers. The Random Pokemon Trainers that weren't seen during the Main Story will usually focus on using one Pokemon Type (much like each Gym Leader), but their Pokemon will be at slightly lower levels and they cannot Dynamax any of their Pokemon.

Cher is one of the fifteen Random Pokemon Trainers you can face when rematching the Champion Cup, having completed the entire Gym Challenge. Cher focuses on using Rock Type Pokemon, having Gigalith, Stonjourner, Shuckle, Sudowoodo, and Barbaracle when in battle. All of Cher's Pokemon will be between Levels 56-58, and, again, none of their Pokemon will Dynamax when in battle. Because of this, Cher is especially weak against Water Type Pokemon & Attacks. Cher also struggles against Grass Type Pokemon & Attacks, since most Rock Types are also weak to them.
