After defeating Marnie & Hop in the Semi-Finals, retrieving Leon from Rose Tower, and defeating Bede one more time, you will finally proceed to the Champion Cup Finals. In order to reach and challenge Leon for The Galar Region Champion, you must defeat three Gym Leaders in a tournament of battles. Your first Finals Opponent will be Nessa, who continues to specialize in using Water Fairy Type Pokemon. In this battle, she will use fix different Pokemon, all of which will fully or part Water Types. Because of this, Nessa is especially weak against Electric & Grass Type Pokemon & Attacks.
Additionally, all of Nessa's Pokemon will either be at Level 51, Level 52 or Level 53. Due to this, it would be wise to have all of your Pokemon at Level 55 or higher. The more experienced your Pokemon are, the easier it will be to defeat Nessa. And finally, Nessa will Gigantamax her final Pokemon, which just so happens will be Drednaw. Because of this, it would be especially wise to wait to use your Dynamax until she sends out Drednaw. Also, it would be smart if the Pokemon you Dynamax is either an Electric Type or Grass Type, since Nessa's Drednaw will be extremely weak to both of those type of attacks.
