Primarina @ Choice Specs
Ability: Torrent
Tera Type: Water
EVs: 252 SpA / 4 SpD / 252 Spe
Modest Nature
- Hydro Pump
- Moonblast
- Psychic Noise
- Flip Turn
Primarina's best set is Choice Specs. Cough.
A boosted Primarina allows itself to become a ridiculously powerful wallbreaker alongside its naturally positive typing on foes like Urshifu, Dragonite, and Gouging Fire makes Primarina, despite its bad physical bulk, able to trade with these threats and pick up important chip on switch ins like Slowking-Galar and Iron Crown. Hydro Pump is it's most powerful STAB move, which with 110 BP is able to singlehandedly 2KHO Slowking-Galar. However, this is without fault, as its Water type STAB can find many resists able to switch in, like Dragonite, Ogerpon-Wellspring, and Serperior, alongside having a deceitfully low accuracy. Therefore, Moonblast is a strong and importantly, more consistent secondary STAB that harder hits foes like Alomomola. Continuing, Psychic Noise is a move specifically chosen to dispatch Toxapex, alongside disabling general recovery and Leftovers on foes like Ferrothorn. Additionally, the combination of Tera Water Hydro Pump and Psychic Noise is able to significantly improve the stall matchup. Finally, Flip Turn can be chosen to pick up momentum versus switch-ins like the aforementioned Ferrothorn, Toxapex, and Iron Crown.
252+ SpA Choice Specs Primarina Hydro Pump vs. 252 HP / 252+ SpD Slowking-Galar: 195-231 (49.4 - 58.6%) -- 98.8% chance to 2HKO

Tapu Lele @ Fightinium Z
Ability: Psychic Surge
Tera Type: Psychic
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
IVs: 0 Atk
- Calm Mind
- Psyshock
- Moonblast
- Focus Blast
Calm Mind Tapu Lele in itself is a super slept-on pick in my opinion, and can surprise teams that too often expect Lele to be choiced, acting as a secondary wincon. It's able to threaten Toxapex for when Primarina Flip Turns into it, and lure Ferrothorn with Fightinium Z. It's a 2-in-1 check to both of Primarina's most effective switch-ins. Secondly, Tapu Lele is notoriously known to be checked by Slowking-Galar and Iron Crown, which Primarina is able to surprise and gain a significant amount of chip into both of them. They have a pretty unique synergy that allows each other to offensively overload, bait, and capture their checks.
+1 252 SpA Tapu Lele All-Out Pummeling (190 BP) vs. 248 HP / 240 SpD Assault Vest Iron Crown: 157-185 (40.9 - 48.3%) -- guaranteed 3HKO
(38.3+40.9=79.2, min rolls need 20% chip)
+1 252 SpA Tapu Lele All-Out Pummeling (190 BP) vs. 252 HP / 216 SpD Ferrothorn: 454-536 (128.9 - 152.2%) -- guaranteed OHKO
Weavile @ Heavy-Duty Boots
Ability: Pressure
Tera Type: Poison
EVs: 252 Atk / 4 SpD / 252 Spe
Jolly Nature
- Swords Dance
- Triple Axel
- Knock Off
- Ice Shard
Swords Dance Weavile, while I was at first in doubt about the set when it was suggested to me by
Runo , it has proven itself in testing to be a formidable offensive pick that compliments Primarina. Swords Dance can take advantage of Primarina and Tapu Lele's switch ins like Slowking-Galar and Iron Crown, and combined with its superior offensive typing can act as a successful primary wincon. It gives us a Knock Off user, which at +2 can cripple and deal huge damage to Toxapex and Alomomola. Triple Axel is generally good STAB and threatens bulky grounds like Landorus and Great Tusk, while also being able to threaten Serperior and Dragonite in the case its pivoted to from Primarina, while also taking advantage of emergency Tera Dragons from the likes of Garganacl. While Ice Shard may seem counterintuitive when paired with Tapu Lele, it's about positioning, amd being able to have Weavile on the field at the right time in which Ice Shard is necessary to pick up a KO when Tapu Lele's terrain isn't in effect. It's Dark typing also gives us immunity from opposing Choice Specs Tapu Lele. Tera Poison may seem like an off-the-wall Tera type, but it can further take advantage of Alomomola, resist Fairy and Fighting Type moves from Iron Valiant and Tapu Lele, common revenge killers, while giving us emergency crutches versus Mega-Lopunny, which this team has a noticable weakness to.
Garganacl @ Leftovers
Ability: Purifying Salt
Tera Type: Dragon
EVs: 252 HP / 4 Def / 252 SpD
Careful Nature
- Recover
- Salt Cure
- Protect
- Stealth Rock
Garganacl here is the resident Fire resist and rocks setter. Rocks Garganacl is in my opinion its best set, as it can noticably lay Stealth Rocks against its checks alongside common defoggers. Salt Cure is an incredibly strong move that not only threatens defoggers like Kartana, Corviknight, and Landorus, but also has great synergy in irritating Primarina's checks in Toxapex and Ferrothorn, while also dealing with emergency defensive Tera Waters. Respectively, Garganacl's checks like Slowking-Galar can be often be overwhelmed by Primarina and Psyshock Tapu Lele. Protect is able to procure more Salt Cure chip against foes like Great Tusk and Landorus-T, while also being able to reveal moves chosen by choice-locked opponents like Tapu Lele, Iron Valiant, and with Tera, Urshifu, which can be especially annoying to predict. Recover is mandatory. Tera Dragon here gives us a defensive Tera option against Ogerpon-Wellspring, alongside giving us an effective check to Charizard-Mega-Y and generally good defensive capability all throughout, covering some of Garganacl's biggest weaknesses in Ground, Water, and Grass moves while retaining its resistance to Fire.
Landorus-Therian (M) @ Choice Scarf
Ability: Intimidate
Tera Type: Water
EVs: 152 HP / 64 Atk / 176 Def / 116 Spe
Jolly Nature
- Earthquake
- U-turn
- Stone Edge
- Defog
This is a standard Choice Scarf Landorus-T, giving us a Ground and Electric immunity alongside more assurance against physically oriented attackers coupled with general speed control. This allows us more flexibility into matchups against Ogerpon-Wellspring, Mega-Lopunny, Tapu Koko, and Mega-Medicham, due to Tapu Lele being able to disguise itself as the Choice Scarf user, and the actual speed control in Landorus being able to pick up surprise KOs on opponents that don't expect it. All moves are self-explanatory, and Stone Edge gives us offensive utility versus Charizard-Mega-Y and Volcarona, and Defog gives us hazard removal. The EVs here have a bit more attack investment as the Smogon sample, as that's outdated to outspeed Zamazenta; this Landorus is set to 271 speed, which outpaces Mega-Lopunny instead.
Ferrothorn @ Leftovers
Ability: Iron Barbs
Tera Type: Ghost
EVs: 252 HP / 40 Def / 216 SpD
Relaxed Nature
IVs: 0 Spe
- Power Whip
- Gyro Ball / Thunder Wave
- Leech Seed
- Spikes
Standard Spikes Ferrothorn here, which slots a Water, Psychic, and Fairy Resist. Dual STAB is chosen, as Power Whip is usually the best attack of choice, and Gyro Ball being able to effectively prevent SubRoost Kyurem from being exceptionally troublesome, but Thunder Wave can be chosen for it's speed drop on foes like Gouging Fire, which Primarina can take advantage of. Leech Seed as recovery, and Spikes as secondary hazards alongside Stealth Rock. Tera Ghost is chosen over Tera Water to stop Rapid Spin from Great Tusk and Landorus-T already holding Tera Water.
or maybe even meme around with Fightinium Z + Superpower
