Moves
Scald packs a decent punch when boosted by rain. One of its most important aspects, though, is its burn chance, meaning it can cripple Pokemon such as Ferrothorn, Amoonguss, and Tentacruel that can't afford to be chipped down. Protect allows Politoed to stall for additional Leftovers recovery and burn or Toxic damage. In addition, it can be used to scout Choice-locked Pokemon such as Latios, allowing you to play around them more safely. The last two moveslots depend on your personal preference and team. Refresh is an excellent move to help deal with Pokemon such as Tentacruel, Heatran, and opposing Politoed that spread status, allowing your Politoed to stay in the game longer. Notably, it allows you to use Politoed as your main switch-in to opposing Scalds so that you do not need to risk Politoed's teammates being burned. Encore is an option to deal with Pokemon such as Calm Mind Reuniclus and Substitute Breloom, which otherwise set up on Politoed for free. Toxic can be used to cripple Politoed's other switch-ins such as Latios, Jellicent, Gastrodon, and Rotom-W. Note that while running Toxic + Encore is viable, it leaves Politoed worn down very quickly by passive damage such as status, sand, and entry hazards, and thus Politoed will require more caution switching into status users.
Set Details
Leftovers improves Politoed's longevity and alleviates its vulnerability to entry hazards. Politoed runs Defense EVs and a Bold nature to serve as a switch-in to Pokemon such as Landorus-T, Excadrill, Mamoswine, and Tyranitar and reduce Pursuit damage. However, a specially defensive spread with a Calm nature is also viable to take hits from special attackers such as Latios, Reuniclus, and Alakazam, and allows it to better handle chip damage from moves like Rotom-W's Volt Switch. Running additional Speed EVs is an option to get the jump on slower Breloom variants and use Encore against them, as Breloom can quickly become a problem for rain teams.
Usage Tips
Politoed's primary objective in a game is to avoid being KOed and keep rain up. Therefore, it is critical to be mindful of its HP. That said, rain teams tend to be more offensive in nature, so it is likely that Politoed will be called upon to act as a temporary buffer against opposing threats. Take care when using Protect or Encore, as either can give a free switch to an opposing Tyranitar, both replacing rain with sand and giving Tyranitar a chance to use Pursuit on Politoed, which can go a long way in winning the weather war. As it runs Protect, Politoed is great at scouting Choice item users such as Latios and Keldeo, so you can double switch Politoed into them and play around them. Feel free to use Scald liberally, as the chip damage even without a burn can be significant, and landing a burn can be huge against Pokemon such as Ferrothorn, Latios, and Rotom-W.
Team Options
A great many Pokemon pair well with Politoed's rain. Politoed's best partner is arguably Tentacruel, which becomes one of the most difficult to KO Pokemon in the game when rain is active thanks to Rain Dish and is almost mandatory on rain teams. Tentacruel can use Rapid Spin to clear entry hazards, improving the longevity of its entire team, and has similar switch-ins to Politoed, meaning they can wear down each other's checks with repeated Scalds and Toxics. Toxicroak is another Pokemon that greatly benefits from rain healing it, and it is an excellent counter to opposing rain teams. Tentacruel and Toxicroak are both solid switch-ins to opposing Keldeo as well, which can cause tremendous damage under rain. Ferrothorn and Jirachi have their Fire weaknesses reduced by rain, can set up entry hazards, and are great switch-ins to opposing Dragon-types such as Latios that can do major damage otherwise. Ferrothorn can also use Knock Off to remove the Leftovers of other Pokemon, most notably other Ferrothorn, making it easier for your offensive Pokemon to break through them and for Politoed and Tentacruel to chip them down with Scalds and burns. Breloom also has its Fire weakness alleviated by rain, and it can switch into Pokemon such as Rotom-W that threaten Politoed and notably pairs well with Jirachi. The most prominent offensive teammate for Politoed is Keldeo, which becomes an immensely powerful wallbreaker with Choice Specs or a great cleaner with Choice Scarf, and it can run other sets to take advantage of Politoed's rain as well. Starmie and Gyarados are also Pokemon that can take advantage of the power boost to Water-type moves granted by Politoed's rain. Thundurus-T and Tornadus have perfect accuracy with Thunder and Hurricane, respectively, in rain, and both Pokemon can force damage onto an opposing Tyranitar, helping keep rain up. They can also provide some defensive utility, switching into Ground-types such as Excadrill and Landorus-T. Latios is another Pokemon that is found on a large number of rain teams, checking opposing Keldeo and Thundurus-T, crippling Pokemon such as Ferrothorn and Reuniclus with Trick, and overall causing mayhem for the opposing team with its powerful attacks. In addition, its Surf is powered up by rain, making Surf a valuable tool for late-game cleaning, and it benefits from Pokemon like Thundurus-T and Tornadus weakening Tyranitar. Dragonite appreciates the removal of sand and the reliable spinning that Tentacruel provides, which let it make better use of Multiscale with its Choice Band, mixed attacker, and Substitute + Dragon Dance sets. Kyurem and Kyurem-B also appreciate the removal of sand and are capable of switching into Grass- and Electric-types that threaten Politoed to force them out. Ground-types such as Landorus-T, Garchomp, and Mamoswine can check Thundurus-T and set up Stealth Rock. Mamoswine can also pick off Dragon-types such as Dragonite and Latios with Ice Shard, and it takes little from Ice-type attacks thanks to Thick Fat, making it a decent offensive check to a weakened Thundurus-T.
