Sierra’s fight is broken up into three waves, making this battle practically have multiple phases you have to persevere through.The first wave always has the same Pokémonfrom Sierra’s team, no matter how many times you encounter her using the Rocket Radar. That being said, Sierra’s second and third waves use one of three possible Pokémon, making it almost impossible to predict which pocket monster is coming next.

Ghost, Poison, Steel
Sierra’s team is one of the trickiest to prepare for among all the Team Rocket leaders, as she has more variety in types than Cliff or Arlo. Despite the lack of some vulnerable patterns, one of the best teams you’re able to assemble for this fight would include:
Gengar is your ace Pokémon to counter Sierra’s Ralts and Gardevoir, whose Fairy and Psychic types are extremely weak to your Ghost/Poison Pokémon. On the other hand, having Swampert on your team prepares for Sierra’s Shadow Steelix, Nidoqueen, or Houndoom, who all suffer super-effective damage to the fully evolved Hoenn Water-type starter.
Swampert may seem like a good Pokémon to use against Sierra’s Milotic but don’t be fooled. The Ground-type on Swampert makes him take normal damage from Water-type attacks Milotic will use, so you should consider using a Mega-Evolved Swampert to prepare for this.
Your final Pokémon, Magnezone, is the best choice to use against the Milotic on Sierra’s team. This group of Pokémondoes not have a direct counter for Sableye, but that Pokémon is far weaker than the Milotic or Steelix you could fight in the second wave. Your team should be able to handle Sableye with normal attack effectiveness, so just attempt to prepare for Sierra’s strongest options.
