Preface
The team was born in the teambuild competition, when Dragonite was chosen as Pokémon of the week. To be honest I'm not a fan of the current metagame, but Dragonite is my favorite Pokémon and I finally found some fun again. During the week I polished the team and as I found it very consistent I come to share the results.
Proof
Teambuilding process

Mavis (Dragonite) (F) @ Choice Band
Ability: Inner Focus
EVs: 252 Atk / 4 SpD / 252 Spe
Adamant Nature
- Dual Wingbeat
- Ice Punch
- Extreme Speed
- Earthquake
I opted for something that was different from boots + DD, but still had offensive power. Choice Band Inner Focus is still unexplored imo and is never a waste, considering the existence of Landorus-Therian. Extremed Speed for priority, Dual Wing Beat for STAB and Earthquake with Ice Punch for needed coverage after Magnezone clears steel types like Ferrothorn and armored birds. Adamant Nature and EVs are standard. The wallbreaker, keep Choice Band safe but if needed, don't be afraid of trade the item for a KO, and feel free to risk some overpredict, the pressure of having the Steel trapped is on the opponent and sometimes they don't switch.
Multiscale x Inner Focus - Initially I thought it was not so necessary to address this, but the comments below have enough discussion for clarification. An extra point is the fact that Inner Focus has immunity to Flinch. Nobody wants to lose to a random Scarf Togekiss or Jirachi.

Freed (Magnezone) @ Chople Berry
Ability: Magnet Pull
EVs: 252 Def / 108 SpA / 148 Spe
Bold Nature
IVs: 0 Atk
- Iron Defense
- Body Press
- Thunderbolt
- Toxic
Magnezone provides vital support for more fluid Dragonite performance. Max Def to maximize damage against Ferrothorn which is too sick to deal with. Chople or Shuca Berry, flip a coin or try to guess Arctozolt's coverage, btw, I prefer Chople as the weakness for Fight is only 2x the chance of surviving is higher. Toxic is for accelerating progress against Landorus-T and others bulky grounds. Speed is 8 points higher than what's on the showdown calculator, to be faster than something that tries to be faster than Magnezone, those additional 8 EVs in Speed were very important to beating others Magnezone in mirror matches.

Happy (Landorus-Therian) (M) @ Leftovers
Ability: Intimidate
EVs: 248 HP / 240 SpD / 20 Spe
Careful Nature
- Earthquake
- Knock Off
- U-turn
- Defog
Landorus-T with Knock Off to remove possible Shed Shell and U-Turn for momentum to help Magnezone eliminate Skarmory, Corviknight and Ferrothorn. With physical Pokémon like Urshifu and Weavile dominating the tier I've put it all for SpDef to be a more durable response against Tapu Koko and Heatran. The speed is to pass 128 speed Heatran and addition to CB Ttar. Avoid taking unnecessary Toxic and Knock Off in favor of a progress that is possible to obtain free of charge a few turns later.

Mira-chan (Toxapex) (F) @ Rocky Helmet
Ability: Regenerator
EVs: 248 HP / 252 Def / 8 Spe (or EVs: 248 HP / 180 Def / 72 SpD / 8 Spe)
Bold Nature
IVs: 0 Atk
- Scald
- Light Screen
- Recover
- Haze
Toxapex is the mixed wall, EVs in physical side, to absorb more damage from Melmetal, Weavile and Urshifu, punishing them with Rocky Helmet. Light Screen is a vital choice for limiting the progress of Future Sight + abusers as well as lessening the pressure suffered by Kyurem and Tapu Lele. Hard switch on Slowtwins to setup Light Screen. Toxapex is an abomination.
One point I missed initially is the importance of these 8 EVs in Speed, as they allow outspeed Melmetal using the same 8 EVs, allowing for a Recover or simply avoiding the chance of DIB Flinch.
Taking into account the weaknesses and comments, Toxapex undergoes a small change, keeping physical bulk to switch in Jolly Weavile 2+ after Stealth Rock, Knock Off, Haze and receive another Knock Off unboosted and recover, Toxapex can still do the same against Adamant Weavile without Stealth Rock and it wouldn't change as much with a physical defense max spread.72 EVs going to SpDef increasing the chance of surviving Nidoking, Kyurem and Zapdos moves.
+2 252 Atk Weavile Knock Off (97.5 BP) vs. 248 HP / 180+ Def Toxapex: 168-198 (55.4 - 65.3%)
252 Atk Weavile Knock Off vs. 248 HP / 180+ Def Toxapex: 57-67 (18.8 - 22.1%)
Stealth Rock 12,5%. 65,3+22,1+12,5 = 99,9.
252 SpA Life Orb Sheer Force Nidoking Earth Power vs. 248 HP / 0 SpD Toxapex: 276-328 (91 - 108.2%) -- 50% chance to OHKO
252 SpA Life Orb Sheer Force Nidoking Earth Power vs. 248 HP / 72 SpD Toxapex: 265-312 (87.4 - 102.9%) -- 18.8% chance to OHKO
252+ SpA Life Orb Sheer Force Nidoking Earth Power vs. 248 HP / 0 SpD Toxapex: 304-359 (100.3 - 118.4%) -- guaranteed OHKO
252+ SpA Life Orb Sheer Force Nidoking Earth Power vs. 248 HP / 72 SpD Toxapex: 283-338 (93.3 - 111.5%) -- 68.8% chance to OHKO
252+ SpA Choice Specs Kyurem Freeze-Dry vs. 248 HP / 0 SpD Toxapex: 278-330 (91.7 - 108.9%) -- 50% chance to OHKO
252+ SpA Choice Specs Kyurem Freeze-Dry vs. 248 HP / 72 SpD Toxapex: 264-312 (87.1 - 102.9%) -- 12.5% chance to OHKO
252 SpA Zapdos Thunder vs. 248 HP / 0 SpD Toxapex: 258-306 (85.1 - 100.9%) -- 6.3% chance to OHKO
252 SpA Zapdos Thunder vs. 248 HP / 12 SpD Toxapex: 254-302 (83.8 - 99.6%) -- guaranteed 2HKO
So, even if you don't want to sacrifice physical bulk, the minimum I recommend is 12 SpDef EVs for Toxapex to withstand Thunder Zapdos Timid and use Light Screen.
252 Atk Weavile Knock Off vs. 248 HP / 180+ Def Toxapex: 57-67 (18.8 - 22.1%)

252+ SpA Choice Specs Kyurem Freeze-Dry vs. 248 HP / 72 SpD Toxapex: 264-312 (87.1 - 102.9%) -- 12.5% chance to OHKO
252 SpA Zapdos Thunder vs. 248 HP / 0 SpD Toxapex: 258-306 (85.1 - 100.9%) -- 6.3% chance to OHKO
252 SpA Zapdos Thunder vs. 248 HP / 12 SpD Toxapex: 254-302 (83.8 - 99.6%) -- guaranteed 2HKO
So, even if you don't want to sacrifice physical bulk, the minimum I recommend is 12 SpDef EVs for Toxapex to withstand Thunder Zapdos Timid and use Light Screen.

Virgo (Clefable) (F) @ Sticky Barb
Ability: Magic Guard
EVs: 252 HP / 228 Def / 28 SpD
Bold Nature
IVs: 0 Atk
- Trick
- Stealth Rock
- Soft-Boiled
- Moonblast
Clefable is the immunity to Dragon, Rocks user and helps Dragonite and Kartana by giving Sticky Barb to some opponent's wall. 28 EVs SpDef to avoid KO from Modest Tapu Lele Specs and reduce 2HKO chances from Shadow Ball Dragapult Specs. The core with Toxapex is the same obnoxious as always, great for limiting progress. Preserving Sticky Barb is obviously important and blocking Leech Seed passive recovery as well.
252+ SpA Choice Specs Tapu Lele Psychic vs. 252 HP / 28 SpD Clefable in Psychic Terrain: 333-393 (84.5 - 99.7%)
252 SpA Choice Specs Dragapult Shadow Ball vs. 252 HP / 4 SpD Clefable: 178-210 (45.1 - 53.2%) -- 32.8% chance to 2HKO
252 SpA Choice Specs Dragapult Shadow Ball vs. 252 HP / 28 SpD Clefable: 174-205 (44.1 - 52%) -- 14.8% chance to 2HKO

Erza (Kartana) @ Choice Scarf
Ability: Beast Boost
EVs: 252 Atk / 4 Def / 252 Spe
Jolly Nature
- Leaf Blade
- Knock Off
- Sacred Sword
- Aerial Ace
Finally, who really ended up standing out was the last addition. With a very consistent but slow team, Kartana offers offensive pressure and needs to be the lead against teams that have Tapu Lele and Kyurem (banned now!). Late game Beast Boost is insane and Kartana's speed allows it to be faster than Arctozolt in hail. I have been using Aerial Ace and it has proven useful against Volcarona and Buzzwole, but feel free to substitute Smart Strike. Because some opponents don't accept the bluff and stay, but even so sacrificing Kartana on turn 1 to remove choice Specs from
TL;DR: Play offensively with Kartana and Dragonite if the matchup is unfavorable, otherwise gradually weaken the opponent's team with the defensive core, open some gaps with Dragonite and finish with Kartana.
Threats





Stall: Shuffle all possible items with Clefable, try some burn with Toxapex, remove the Steel type and be careful with Dragonite.

Try to keep Light Screen whenever possible. Multiscale Dragonite has its merits here (252+ SpA Life Orb Sheer Force Nidoking Ice Beam vs. 0 HP / 0 SpD Multiscale Dragonite: 273-322 (84.5 - 99.6%), but luckily Nidoking is unusual at this point in the metagame.

Conclusion
After a long time I found some fun and consistency in the same team despite some flaws that every team has. Maybe it's not the style of those who prefer to play more aggressively, but I hope you all enjoy it and have a great day!
