Arcanine (F) @ Aguav Berry
Ability: Intimidate
Level: 50
EVs: 252 HP / 188 Def / 52 SpD / 12 Spe
Calm Nature
IVs: 0 Atk
- Protect
- Snarl
- Roar
- Flamethrower

Exactly the same as Mike Suleski's Arcanine from Athens Regionals, except that with Gigalith being such a prominent part of my team, Morning Sun wasn't viable. I elected to go with Roar to help against Trick Room and random stuff like Eevee.

Magnezone @ Choice Specs
Ability: Sturdy
Level: 50
EVs: 252 HP / 252 SpA / 4 SpD
Modest Nature
IVs: 0 Atk / 30 SpA
- Thunderbolt
- Flash Cannon
- Volt Switch
- Hidden Power [Grass]

Elected to go Hidden Power Grass over Gavin's Ground because I had other ways to deal with opposing Magneton and Marowak, and I wanted a way to hit Gastrodon hard. In hindsight, I should have run 36 Speed EVs to outspeed 252+ Garchomp in Tailwind.

Tapu Fini @ Leftovers
Ability: Misty Surge
Level: 50
EVs: 244 HP / 148 Def / 68 SpA / 4 SpD / 44 Spe
Calm Nature
IVs: 0 Atk
- Protect
- Muddy Water
- Calm Mind
- Moonblast

Nothing to say here, pretty standard Calm Mind Fini set. Muddy Water's accuracy drop was on display in a hilarious Game 1 in my set against Kyle Morris, where I managed to give three separate Pokémon a drop on three Muddy Waters.

Garchomp @ Brightpowder
Ability: Sand Veil
Level: 50
EVs: 12 HP / 204 Atk / 4 Def / 36 SpD / 252 Spe
Jolly Nature
- Protect
- Poison Jab
- Swords Dance
- Earthquake

You can give me all the shit you want about using Brightpowder Garchomp, and it's probably deserved, but it came in clutch in quite a few matches. I did miss having Groundium Z in a few matches, and I'd consider running Fire Fang or Rock Slide over Swords Dance in the future so I can actually hit Celesteela.

Mandibuzz @ Misty Seed
Ability: Overcoat
EVs: 252 HP / 52 Def / 184 SpD / 20 Spe
Calm Nature
IVs: 0 Atk
- Snarl
- Tailwind
- Foul Play
- Roost

20 Speed lets it outpace Modest Pheromosa in Tailwind. I kind of forget what the rest of the spread does, but it survives Life Orb Koko Thunderbolt 100% of the time. Probably MVP of the team. #TrustTheBird

Gigalith @ Rockium Z
Ability: Sand Stream
Level: 50
EVs: 252 HP / 4 Atk / 252 SpD
Relaxed Nature
IVs: 0 Spe
- Wide Guard
- Stone Edge
- Toxic
- Heavy Slam

Could definitely stand to optimize this spread, but it works as is. I elected for Toxic to help deal with Porygon2 and other threats that just kind of sit there and soak damage. Just make sure Misty Terrain isn't up when you use it. I may have neglected this more than once.

Fun fact: Z-Wide Guard gives you a +1 Defense boost. Other fun facts:

252 Atk Garchomp Tectonic Rage (180 BP) vs. +1 252 HP / 0+ Def Gigalith: 152-180 (79.1 - 93.7%) -- guaranteed 2HKO
252+ Atk Guts Hariyama Close Combat vs. +1 252 HP / 0+ Def Gigalith: 156-186 (81.2 - 96.8%) -- guaranteed 2HKO
252+ Atk Pheromosa High Jump Kick vs. +1 252 HP / 0+ Def Gigalith: 122-146 (63.5 - 76%) -- guaranteed 2HKO
-1 252+ Atk Water Bubble Araquanid Hydro Vortex (160 BP) vs. +1 252 HP / 0+ Def Gigalith: 132-156 (68.7 - 81.2%) -- guaranteed 2HKO (OK, you need help from Arcanine for this one)
