Best team and strategy to beat Sierra in Pokemon GO (September 2025)

The following is Sportskeeda Gaming's choice for the best team to defeat Sierra:

Regieleki with Volt Switch/Lock-On, and Thunder Cage*

Regieleki will easily melt Shadow Feebas. Not only is it fast, but it also has type-advantage and stats. The Fast Move spam on Shadow Feebas should let you charge up to land a Charged Move on the second Pokemon Sierra sends.

You will deal double damage if Shadow Staraptor is sent out, or do neutral damage to Shadow Mismagius. That said, you will do less damage to Shadow Ferrothorn or break one shield.

Tyranitar with Bite, Brutal Swing, and Stone Edge

After Regieleki faints, bring out Tyranitar to deal with the second phase of Sierra's September 2025 team in Pokemon GO. Tyranitar is so powerful that even when it hits neutrally, it can mow down this part of the lineup.

Tyranitar deals super-effective damage against Shadow Mismagius and Shadow Staraptor. You could run Fire Blast on Tyranitar as well to counter Shadow Ferrothorn. Additionally, you can run Shadow or even Mega Tyranitar for faster results.

Primal Groudon with Mud Shot, Precipice Blades*, and Fire Blast

Primal Groudon is the perfect counter to the final phase of Sierra's team. It resists most of Shadow Houndoom, Shadow Camerupt, and Shadow Drapion's best attacks and can hit back with super-effective Ground-type damage. Primal Groudon with Fire Blast is an additional counter to Sierra's Shadow Ferrothorn. It's the best way to clean up the endgame when shields are down.
