Since their addition into the game back in 2019, Team GO Rocket have added a different dimension to Pokemon GO.

Their Shadow Pokemon have helped shape the meta and they’ve helped lay the foundations for a variety of events.

More recently, they’ve been the source of 12km eggs and part of the Luminous Legends X event, with players tasked to beat Cliff, Arlo, Sierra and ultimately, Giovanni.

With that in mind, here’s how to beat Sierra in Pokemon GO in May 2021.

Best Team Composition

While there’s no hard and fast “Best Team” to tackle Sierra, due to the fact that she can change up her party from one battle to the next, you can still pick smart.

These are the Pokemon I would be taking into battle with me against Sierra:

  • Lucario
  • Mega Venusaur
  • Rampardos

However, should Sierra bring out something you’re not covered against, ideally, your best bet is to retreat and come back to battle prepared, unless you’re in a really strong position.
