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 Avery (if playing Pokemon Shield), your Rival on the Isle of Armor, and he will always bring into battle Level 68 Galarian Slowbro, Level 69 Alakazam and Level 70 Galarian Slowking that will be able to Dynamax.
No matter what Pokemon you use, it would be smart to have higher leveled Pokemon when facing the Galarian Star Tournament. Because Avery specializes in using Psychic Type Pokemon, his Pokemon are especially weak against Ghost Type Moves and Dark 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 90-100 Pokemon will usually handle any Level 70 Pokemon with ease.
