Question

Miraidon @ Choice Specs
Ability: Hadron Engine
Tera Type: Electric
EVs: 4 Def / 252 SpA / 252 Spe
Timid Nature
- U-turn
- Flash Cannon
- Draco Meteor
- Electro Drift

First "sweeper" of the team, nukes everything but Ground-types with Electro Drift. U-Turn if I predict a Ground switch-in like Iron Treads, Flash Cannon for Fairies like Flutter Mane, DM for opposing Miraidon and Koraidon.

Espathra @ Leftovers
Ability: Speed Boost
Tera Type: Fairy
EVs: 204 HP / 204 Def / 100 Spe
Bold Nature
IVs: 0 Atk
- Protect
- Lumina Crash
- Baton Pass
- Calm Mind

My main "gimmick" Pokemon. Protect to get a Speed Boost that outspends the big unboosted 3 of Flutter Mane, Koraidon, and Miraidon, Calm Mind to collect boosts for Baton Pass, and Lumina Crash for not being Taunt fodder. The odd EVs maximize physical bulk whilst outspeeding the aforementioned 3. Tera Fairy is a nice defensive type to resist U-Turn and Sucker Punch. However, if a Taunter switches in, its best to just Baton Pass to the next one:

Chi-Yu @ Leftovers
Ability: Beads of Ruin
Tera Type: Psychic
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
IVs: 0 Atk
- Flamethrower
- Dark Pulse
- Psychic
- Taunt

My main sweeper. Taunt to stop setups, Flamethrower and Dark Pulse for STAB, Tera Psychic and Psychic for nice coverage. Beads of Ruin is overpowered with Calm Mind and Speed Boosts from Espathra. Espathra & Chi-Yu form a nice pairing, with each's weaknesses mostly flipped by the other.

Iron Treads @ Assault Vest
Ability: Quark Drive
Tera Type: Ground
EVs: 252 Atk / 4 SpD / 252 Spe
Jolly Nature
- Rapid Spin
- Earthquake
- Heavy Slam
- Knock Off

One of my more unsure picks on the team. A solid EQ user and spinner, Knock Off for utility, Heavy Slam for STAB. Pretty average set, but I may replace Knock Off with Stealth Rock.

Koraidon @ Choice Band
Ability: Orichalcum Pulse
Tera Type: Fire
EVs: 252 Atk / 4 SpD / 252 Spe
Jolly Nature
- Flare Blitz
- Outrage
- U-turn
- Collision Course

Haha, Choice Band Outrage go brrr. Pretty average Banded Koraidon set, and Tera Fire Orichalcum Pulse Flare Blitz can take out some resists as well. U-Turn works well to lead as a scout.

Kingambit @ Leftovers
Ability: Supreme Overlord
Tera Type: Ghost
EVs: 252 HP / 252 Atk / 4 SpD
Adamant Nature
- Sucker Punch
- Iron Head
- Kowtow Cleave
- Swords Dance

Another unsure member. This is my only priority user, as Paladin would be a bit unreliable with Koraidon. Most of the set is self-explanatory, Tera Ghost to evade Fighting.

All in all, I'm unsure about my Steels in Iron Treads and Kingambit, but the rest is nice in my opinion. Got me to >1500 Elo as well. Rates and comments are greatly appreciated, thanks for reading!

Comments

I feel like Overheat may be better for Miraidon for coverage against switchins like Iron Treads.  The only prevalent Fairy is Flutter Mane which Kinggambit takes care of with Sucker Punch.

252+ Atk Supreme Overlord 3 allies fainted Kingambit Sucker Punch vs. 0 HP / 0 Def Flutter Mane: 271-321 (107.9 - 127.8%) -- guaranteed OHKO

I still don’t trust Kingambit to be able to wait that long against Flutter Mane, plus the Calm Mind set makes prediction challenging. It needs 3 fainted allies for a guaranteed OHKO. I’ve found that I barely ever use Overheat, as the AG members with weaknesses to it, like Chien-Pao and Corviknight, are easily taken care of with Electro Drift. I would rather speed tie with FM and use Flash Cannon than wait for Kingambit. U-Turn to Koraidon for Iron Treads.

Ok, that's understandable.  Why did you go 252 HP on Kingambit rather than the traditional Smogon spread, which gives it notable opponents to outspeed?

---

I don’t remember specifically the reason for 252 HP, but I know that the Smogon speed EVs are to outspeed Corviknight, Alomomola, Skeledirge, Iron Hands. Iron Hands is obsolete in AG, I would switch to Miraidon for Alomomola, and I wouldn’t keep Kingambit on Corviknight due to Body Press or Skeledirge due to Torch Song.
