The usual Pokemon GO enemies - Sierra, Cliff, and Arlo are all back this month and players will want to defeat every one of the bosses to earn some exciting Shadow Pokemon encounters and other rewards on their way to a showdown with Giovanni. Trainers will want to keep in mind that each of the GO Rocket bosses in has their own strengths and weaknesses and players should be sure to optimize their counter rosters before heading into these battles.
This month's lineup for Sierra features some familiar face, but there are a few tweaks that players will need to take note of. Like a few times in the past, Sierra kicks off the fight with Drowzee. After that there will be a bit of a surprise as the second and third slots both include a handful of different options. Luckily players should have plenty of counters available once they figure out who they are actually up against. Due to the random nature of the second and third Pokemon, players may need to take a fall on the first attempt just to learn some information and tweak their roster.

Giratina (Origin) - Shadow Claw/Ominous Wind
Hydreigon - Bite/Dragon Pulse
Moltres - Wing Attack/Sky Attack
Latios - Zen Headbutt/Psychic
Kyogre - Waterfall/Surf
Dialga - Dragon Breath/Draco Meteor
Lucario - Counter Power Up/Punch

Many of the best counters for this battle are relevant to the current Pokemon GO PvE and PvP metagame, so it's worth investing in them beyond this fight for most players. Use TMs and Rare Candy wisely if they are needed to take down this challenger. There are lots of alternatives that can work as substitutes for this ideal roster, but most players shouldn't have much trouble assembling the team recommended above.
