Although Tier 3 Pokemon GO bosses are possible to solo, that is only the case if players understand the boss' weaknesses and assemble a strategic counter roster. Each Pokemon has its own strengths and weaknesses and part of preparing for an effective Battle Raid means studying those weaknesses and forming a respectable counter roster. Players who are ready to face off against Cloyster have a handful of important weaknesses to focus on to maximize their performance in the Battle Raid.
Usually Pokemon GO Battle Raid fans are focused on Legendary and Mega bosses, but tier three challenges shouldn't be overlooked. The lower tier Battle Raids can often be solo'd and offer an easier path to completing raid-relates Field Tasks in addition to providing some powerful item and encounter rewards. Cloyster has some great uses in the current PvP and PvE meta game, so trainers will want to take advantage of this Battle Raid any time it pops up.
Cloyster's Water- and Ice-type pairing gives players a handful of weaknesses as options and just a handful of resistances to keep in mind, as well. Although tier 3 Battle Raids aren't as challenging as Legendary and Mega showdowns, trainers may still want to take the time to spend some Stardust, Candy, and Elite TMs to get everything in order before the fight.

High level players with the best counters can technically solo this tier three raid boss, but players who want to play it safe should enter the fight with one or two friends instead to secure a successful battle.
