Best team to beat Sierra in Pokemon Go

The best team to beat Sierra consists of Mewtwo, Xurkitree, and Mega Lucario.

One of the best teams you can use when battling Sierra in Pokemon Go consists of Xurkitree, Mega Lucario, and Mewtwo. Be aware that this team isn’t going to work in every scenario, so it’s more of a general recommendation that you can shake up as needed.

The most important thing you can have on your team is an Electric-type Pokemon like Xurkitree as it will be a helpful counter to the second phase of Sierra’s battle with Electric and Fairy attacks that can take down Sableye and Milotic. 

The addition of Mega Lucario to the team provides a strong cover for the stages involving Houndoom and Carvanha.

Mewtwo is a strong hard-hitter who will be in charge of taking down Nidoqueen and Alakazam, while also being able to stand its ground against Ampharos if required.
