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. Unlike the Random Pokemon Trainers, the Gym Leaders and other Main Characters have stronger Pokemon and each have the ability to Dynamax/Gigantamax one of their Pokemon.
Even though Piers has since retired from being a Gym Leader, you can still face him when rematching the Champion Cup. Piers still focuses on using Dark Type Pokemon, having Scrafty, Malamar, Skuntank, Toxtricity, and Obstagoon when in battle. All of Piers' Pokemon will be between Levels 60-62, but unlike the other Main Characters and Gym Leaders you can have a rematch against, he won't be able to Dynamax/Gigantamax any of his Pokemon. Because of this, Piers is still weak against Fighting Type and Bug Type Pokemon & Attacks. Piers is also weak against Ground Type Pokemon & Attacks, since two of his Pokemon are part Poison Type and said Pokemon are weak against them.
After defeating both the Isle of Armor and Crown Tundra DLC Packages, Piers' Champion Cup Rematch Pokemon Team will have changed slightly. All of his Pokemon will now be at higher levels.
