Why not post this here in addition to my yearly log-in to hype the forum teams coming back. Got an Articuno tattoo last year so I made this team to get an in game one to Master Rank.

Built this team back in July for Reg G for the sole purpose of getting Articuno to Master Rank on SV. It worked really well and hit from zero to Master Ball with only two losses.


Mochi (Ninetales-Alola) @ Focus Sash
Ability: Snow Warning
Level: 50
Tera Type: Fairy
EVs: 4 HP / 4 Def / 244 SpA / 4 SpD / 252 Spe
Timid Nature
- Aurora Veil/Helping Hand
- Encore
- Icy Wind
- Moonblast

EVs: Max Spd and S.atk, too frail and sash to not invest in defenses.
Role: Often leads and sets snow for Articuno. Icy wind to drop speed on non-TR teams, Encore to punish set up and WG, Aurora veil for screens if they have no weather answers, though I have mostly replaced it with helping hand to boost damage since it's so common for opponents to remove snow quickly. Also benefits leading with Kyogre since Drizzle will overwrite snow.
Tera: Not really used but to hit Moonblast as hard as possible.


Freezer (Articuno) @ Never-Melt Ice
Ability: Snow Cloak
Level: 50
Tera Type: Ice
EVs: 188 HP / 92 Def / 196 SpA / 4 SpD / 28 Spe
Modest Nature
- Blizzard
- Protect
- Freeze-Dry
- Hurricane

EVs: Speed outpaces max Urshifu at -1, S.atk OHKOs Bulky Urshifu-R and Ogrepon-W with Freeze Dry.
Role: Pretty flexible for leading or late game. Takes advantage of snow and rain to spam Blizzards or Hurricane . Freeze dry adds coverage and a stable move when weather is gone.
Tera: Ice spam and removes electric weakness to survive Miradon.


Basil (Hitmontop) @ Eject Pack
Ability: Intimidate
Level: 50
Tera Type: Steel
EVs: 188 HP / 252 Atk / 4 Def / 12 SpD / 52 Spe
Adamant Nature
- Fake Out
- Bullet Punch
- Wide Guard
- Close Combat

EVs: Outpaces incineroar. Max attack and remainder into bulk.
Role: Leads with Farigiraf to set TR up and CC+Eject pack to get Kyogre or Goodra in. Wide Guard blocks spread spam, Bullet punch and Tera to fight/survive DK+Fairy Caldrex-S, Flutter Mane and Chien-Pao.
Tera: Not often used but keeps Top from being wiped by Flutter mane and Psyspam.


Evil Olive (Farigiraf) @ Safety Goggles
Ability: Armor Tail
Level: 50
Tera Type: Ground
EVs: 108 HP / 44 Def / 156 SpA / 196 SpD / 4 Spe
Modest Nature
- Trick Room
- Ally Switch
- Hyper Voice
- Shadow Ball/Foul Play

EVs: From Smogon site, Offensive set. Survives Ursaluna-B's HH+HV and BM and Urshifu-R's SS.
I did stray from the offensive set but kept the EVs as they always held well. Googles to prevent Spore and Tera ground solely for Miradon attempting to nuke with Electro Drift.
Role: Leads to set up TR and protect allies with Armor Tail and Ally switch, Hyper Voice for decent chip and Shadow ball for both Caldy and Gholdengo/Flutter Mane, though I've flopped between it and Foul play to hit Caldrex-I harder at the cost of less damage to the others.
Tera: Ground to Keep Miradon from Nuking it.


Consommé (Kyogre) @ Assault Vest
Ability: Drizzle
Level: 50
Tera Type: Grass
EVs: 236 HP / 12 Def / 236 SpA / 4 SpD / 20 Spe
Modest Nature
- Water Spout
- Origin Pulse
- Ice Beam
- Thunder

EVs. Outpaces Max 101's at -1, Rest into Bulk and S.atk.
Role: Using either Ninetales's Icy wind or TR to get the speed advantage and spam Water Spout. Origin pulse if HP is low and Ice beam/Thunder for coverage and hitting Wide guard users.
Tera: Grass covers it's Grass/Electric weaknesses and blocks Spore.


CinnamonRoll (Goodra-Hisui) @ Leftovers
Ability: Sap Sipper
Level: 50
Tera Type: Ghost
EVs: 236 HP / 252 Def / 4 SpA / 12 SpD
Relaxed Nature
- Shelter
- Life Dew
- Body Press
- Muddy Water

EVs: Max defense for taking hits and Body press.
Role: Typically late game to set up a win con against physically heavy teams, and tie with Zamazenta. Life dew keeps Himself, Kyogre and Articuno going while Top and Farigiraf can give time to set Shelters up. Sap sipper to give more guards to spore and Rillaboom. Muddy water is a weak spread but is boosted by rain and the accuracy drops can give more time to heal.
Tera: Ghost to block opposing Body press and buy a turn against Urshifu.
