Despite having no specific team that can dominate Sierra in July, there are a few things you can do to get the upper hand. You can also use a Squirtle against Sierra. This type is very weak to Electric and Grass attacks, but its pure Water nature makes it an excellent choice to burn through Sierra’s shields. Also, it is a good match up for Decidueye and Mega Venusaur, which are both good against Sierra.
In July 2021, Sierra has not changed her Pokemon lineup much. Her first-round pick is Sneasel, followed by Ampharos. In the second round, she uses Crobat. In the third round, she switches to Magnezone. In the final round, she switches to Scizor.
To beat Sierra, make sure to use your strongest Pokemon that are weak to Ground and Flying. This way, you can avoid being swarmed by her pure Electric-type Pokemon. Regardless of which type you choose, be sure to bring your strongest counters. Psychic-type Pokemon are also a good option. These Pokemon are very weak against Bug, Dark, and Ghost types, so you should bring your best Pokemon to beat them.
If you can’t find a good Pokemon, try using a Ground type Pokemon. Sierra is ready for Ground-type Pokemon, so you may want to bring one or two along. However, it is best to use those Pokemon only after you’ve sent out the Drapion. Drapion is too weak to deal large damage to Steel-type Pokemon, so you can use Metagross or Melmetal to bait the attacks of the Drapion.
Another way to beat Sierra is to defeat the Team Rocket Leaders. This can be done by defeating six Team Rocket Grunts and using the Mysterious Component you get from them. This will give you access to the Rocket Radar, which will help you take down the leader. When the Team Rocket Leaders attack the players, Sierra will be vulnerable to their attacks. This is why it is important to use counters to defeat Team Rockets.
Another way to beat Sierra is to use the dual type Blaziken. This Pokemon has several weaknesses, including Psychic, Flying, and Ground. You can also use a Shadow Lapras to deter other players with a high defense. If you can’t find a Fire-type Pokemon, try using a Water-type Pokemon such as Magnezone.
If you’re not sure which Pokemon to use, make sure to get a Pokemon with Charged Attack. It will allow you to get through Sierra’s Protect Shields in a hurry. This will also enable you to make use of the Pokemon’s Charged Attack later on.
A good choice for Sierra’s second Pokemon is Blaziken. This Water-type Pokemon is also weak against Electric and Fighting, making it a good choice against Sierra. Another option is a Water-type Pokemon like Lapras or Sharpedo.
