When challenging the Galarian Star Tournament, you will eventually have the choice between seventeen different trainers to Pair with or face off against. No matter whether you pair with them or they oppose you, their Pokemon teams will never change. One of these seventeen trainers is none other than Mustard, the Dojo Master on the Isle of Armor, and he will always bring into battle Level 80 Mienshao, Level 80 Kommo-o and Level 80 Urshifu that will be able to Gigantamax.
No matter what Pokemon you use, it would be smart to have higher leveled Pokemon when facing the Galarian Star Tournament. Because Mustard specializes in using Fighting Type Pokemon, his Pokemon are especially weak against Fairy Type Moves and Flying Type Moves. With all of that said, however, it really doesn't matter what Pokemon you use as long as they are at incredibly high levels. As long as your Pokemon aren't weak to certain other Pokemon Attacks, a Level 100 Pokemon will usually handle any Level 80 Pokemon with ease.
