Tapu Fini @ Leftovers
Ability: Misty Surge
EVs: 252 HP / 116 Def / 140 Spe
Bold Nature
- Calm Mind
- Taunt
- Scald
- Draining Kiss
Taunt turns Pokemon that rely on status moves to damage Tapu Fini such as Blissey and Toxapex into setup fodder. It also prevents Slowking from using Teleport and Pokemon like Corviknight and Clefable from using their recovery moves, forcing them to play more carefully to avoid being worn down. Scald is weaker than Surf, but it discourages Pokemon not protected by Misty Terrain, such as Landorus-T and Rillaboom, from switching in due to the threat of a burn. Draining Kiss is preferred over Moonblast to make Tapu Fini less easily worn down, but Moonblast can be considered for its greater immediate power. 140 Speed EVs are used to outspeed Bisharp and Timid Magnezone. The Defense EVs and Bold nature are used because Calm Mind already boosts Tapu Fini's special bulk.
Magnezone @ Leftovers
Ability: Magnet Pull
EVs: 4 HP / 252 Def / 252 Spe
Timid Nature
- Iron Defense
- Body Press
- Thunderbolt
- Toxic
Iron Defense + Body Press Magnezone traps Pokemon that its STAB moves cannot threaten while also pressuring certain special walls that can switch into its attacks otherwise, such as Blissey. Ferrothorn is the main target, as it is one of the best defensive Steel-types that resists Electric and Steel, but this set is still able to trap typical targets like Skarmory and Corviknight with Thunderbolt. Substitute is very useful alternative to block common status moves such as Ferrothorn's Leech Seed and get one more hit off after taking down a Steel-type. Toxic allows Magnezone to badly poison switch-ins such as Landorus-T and Swampert that can exploit Magnezone, while Teleport allows for Magnezone to gain momentum against them and other Ground-type Pokemon instead.
Slowking-Galar @ Assault Vest
Ability: Regenerator
EVs: 252 HP / 12 Def / 124 SpA / 120 SpD
Calm Nature
IVs: 0 Atk
- Future Sight
- Sludge Bomb
- Flamethrower
- Ice Beam
Assault Vest allows Galarian Slowking to act as a special tank, sponging hits from the likes of Clefable, Tapu Koko, and Tapu Fini and threatening them out with it's STAB moves. Future Sight may be used along with powerful attackers like Urshifu-R and Bisharp to break through Pokemon such as Toxapex and Buzzwole. The combination of Future Sight and Sludge Bomb also allows Galarian Slowking to easily break through and damage Substitute users like Kyurem and Zapdos. However, Psychic may be used for more immediate damage to Toxapex and Urshifu-R. Flamethrower can be used to punish Steel-Type Pokemon like Ferrothorn and Corviknight that would normally attempt to switch into Galarian Slowking on an expected Future Sight. Scald is used to punish switch-ins to opposing Ground-Types such as Hippowdon, Landorus, and Excadrill, chipping them down and possibly crippling them with burn. It may also be used to chip down Heatran, which is otherwise unaffected by most of Galarian Slowking's moves. Hydro Pump may also be used to greatly chip Heatran and other Ground- and Fire-types at the price for being unable to fish for burns on other Pokemon and lower accuracy. Unlike Scald, Hydro Pump allows Galarian Slowking to 3HKO Specially Defensive Heatran, and can 2HKO defensive Ground-types like Landorus-T and Hippowdon. Ice Beam can also replace Scald as a higher power move that specifically targets Ground- and Dragon-types like Landorus-Therian, Dragapult, and Garchomp. 252 HP EVs 12 Def EVs and 120 SpD EVs coupled with a Calm Nature and Assault Vest allow Galarian Slowking to tank 2 Choice Specs Shadow Balls from Dragapult and also allow it to live 1 Choice Banded Surging Strikes from Urshifu-R. The remaining EVs are put into Special Attack to maximize its offensive presence. However, if the Dragapult threshold is not necessary for the team, a Modest nature can be run for increased damage with Future Sight and in general.
Weavile @ Heavy-Duty Boots
Ability: Pressure
EVs: 252 Atk / 4 SpD / 252 Spe
Jolly Nature
- Swords Dance
- Triple Axel/ Icicle Crash
- Knock Off
- Ice Shard
Swords Dance allows Weavile to be one of the best late game cleaners in OU. After some prior chip damage, Weavile is able to break past its usual checks such as Clefable, Toxapex, and Corviknight, and sweep through the opposing team. It gains setup opportunities on forced switches from Pokemon like Galarian Slowking and Landorus-T, as well as more offensive threats like Garchomp, Hydreigon, Choice-locked and Dragapult. While Triple Axel is an incredibly strong Ice-type STAB, its unreliability can lead some to prefer Icicle Crash, which has higher accuracy and avoids contact at the cost of much of its power, which is especially noticeable against Clefable, Buzzwole, and Skarmory. Weavile uses Knock Off on defensive Pokemon during the early game, removing key items like Corviknight's Leftovers or Rocky Helmet, Buzzwole's Heavy-Duty Boots or Rocky Helmet, and Clefable's Leftovers, in order to help chip these targets down more easily, often via hazards damage or pivoting teammates, in preparation for an endgame with Triple Axel. Ice Shard has use in revenge killing faster threats like Dragapult, Speed-boosted Garchomp, and Hawlucha, and can help facilitate an endgame sweep by picking off weakened revenge killers like Tapu Koko and Zeraora. An Adamant Nature is primarily used to deal much more damage to typical checks, most notably increasing rolls to OHKO Clefable while dealing heavily increased damage to Corviknight and Toxapex. A Jolly Nature can alternatively be used on teams lacking speed control or those extremely weak to Tornadus-T.
Landorus-Therian @ Leftovers
Ability: Intimidate
EVs: 252 HP / 164 Def / 92 Spe
Impish Nature
- Stealth Rock
- Earthquake
- U-turn
- Defog/Stealth Rock
Defensive Landorus-T is a great Stealth Rock setter by virtue of its good typing and Intimidate, which help it switch into many physical attackers including Garchomp and Excadrill to sponge hits. U-turn allows it to safely pivot out against checks like Corviknight, Hippowdon, and opposing Landorus-T as well as keep up momentum during a match. Knock Off cripples any Pokemon that switches in by removing their item; this makes Landorus-T much more annoying to switch into. Removing Heavy-Duty Boots from Pokemon like Tornadus-T, Zapdos, and Mandibuzz is especially useful, as it leaves them vulnerable to Landorus-T's Stealth Rock. Toxic is an alternative that cripples Pokemon like Tangrowth, Slowbro, and opposing Landorus-T. It's also especially useful for pressuring Defoggers such as the aforementioned Tornadus-T and Mandibuzz. Leftovers provides Landorus-T with passive recovery, which somewhat mitigates its problem with longevity. 92 Speed EVs are used to outspeed Bisharp and specially defensive Heatran as well as positive-natured base 60s such as Magnezone and Aegislash.
Kartana @ Choice Band
Ability: Beast Boost
EVs: 252 Atk / 4 SpD / 252 Spe
Jolly Nature
- Leaf Blade
- Smart Strike
- Knock Off
- Sacred Sword
Swords Dance Kartana is a premier wallbreaker because of its immense power. Its ability to steamroll its common Flying-type checks when boosted or slowly whittle them down with Knock Off and entry hazard support makes it nearly uncheckable. Knock Off targets Flying-type switch-ins like Mandibuzz, Zapdos, and Tornadus-T, as well as hitting Galarian Slowking and Volcarona. By removing their items, Kartana ensures that it or one of its teammates has an easier time breaking through later. Sacred Sword lets it break through Steel-types such as Ferrothorn and Heatran more easily. Sacred Sword also lets Kartana beat Iron Defense Corviknight and Skarmory by bypassing their Defense boosts. Synthesis is an alternative to ensure Kartana defeats Corviknight while healing off Life Orb recoil. It is especially valuable on bulkier teams, where Kartana can be useful even after eliminating Corviknight. However, forgoing Sacred Sword results in harder matchups against other Steel-types like Ferrothorn and Heatran. A Jolly nature is used to outspeed and possibly revenge kill common offensive threats like Garchomp and Hydreigon. Life Orb is especially useful when trying to break through common defensive walls like Corviknight, Zapdos, and Tangrowth
