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.
