Decisions

  1. Team preview
    Claude Haiku 5.5 led with Garganacl2,914 tok · 5.1 s · $0.0006

    Garganacl leads well here. Stealth Rock chips the opponent's fast threats like Dragapult and Gholdengo over the whole game, and Purifying Salt gives it solid bulk against Ogerpon and Kingambit's pressure.

    Reasoning trace (44 words)
    I'm weighing lead options against their team of Great Tusk, Gholdengo, Dragapult, Ogerpon, Raging Bolt, and Kingambit — considering Garganacl for Stealth Rock given their numerous threats, versus a fast Choice Specs Dragapult or an Intimidate Landorus lead to blunt their physical attackers.
    
    
    GPT-6 Luna Pro led with Ogerponwellspring9,040 tok · 16.0 s · $0.0016

    Ogerpon-Wellspring pressures three of the opponent’s likely bulky leads—Great Tusk, Garganacl, and Landorus-T—and can Knock Off a Gholdengo switch-in. That strong matchup into their ground-heavy core makes it the best lead.

  2. Turn 1
    Claude Haiku 5.5 used Stealthrock2,664 tok · 4.8 s · $0.0004

    Garganacl is slower than Ogerpon-Wellspring, and Earthquake would be wasted into Water Absorb's typing, since Ogerpon-Wellspring is Grass/Water and only takes neutral Ground damage. Setting Stealth Rock on turn 1 is the standard value play with no tera needed.

    Reasoning trace (27 words)
    I'm considering turn 1 with Garganacl setting Stealth Rock against Ogerpon-Wellspring, which has Water Absorb and a Grass/Water typing, so Water-type moves won't threaten it much.
    
    
    GPT-6 Luna Pro used Ivycudgel7,492 tok · 10.9 s · $0.0010

    Ogerpon is much faster and Ivy Cudgel hits Garganacl super effectively, giving the best immediate pressure. Tera is unnecessary when a strong non-Tera hit can threaten a 2HKO.

    Reasoning trace (152 words)
    **Analyzing Ogerpon strategies**
    
    I need to analyze Ogerpon's moves against Garganacl. It seems Ivy Cudgel could be super effective, maybe even an OHKO. Garganacl, being bulky, has an attack power of 339 and a 100 BP, likely doing about 60-70 damage. Garganacl can use Salt Cure and recover. Using Swords Dance might entice the opponent to switch, but it could also be risky with Garganacl's potential Tera. I should weigh my options carefully for the best action to take.**Evaluating Ivy Cudgel's potential**
    
    I’m assessing whether Ivy Cudgel will hit 100 power. If I use Tera, it could gain STAB and potentially become a near OHKO, but I’m wondering if there's a reason to use Tera now. It seems like it might be more effective to use non-Tera Ivy Cudgel instead. I need to weigh the advantages and consider how best to maximize my damage output without wasting my Tera at this point.
  3. Turn 2
    GPT-6 Luna Pro used Ivycudgel7,094 tok · 7.3 s · $0.0008

    Ogerpon is much faster than Garganacl, and Ivy Cudgel already dealt enough damage to finish it from 44%.

    Reasoning trace (77 words)
    **Considering battle strategy**
    
    I need to think about using Ivy Cudgel since it might knock out the opponent at 44 HP. It was super effective last time, dealing 62% to Garg, so I expect it could secure a knockout this time too. The opponent is slow—Ogerpon has a speed of 350 compared to my 35. Ivy Cudgel is definitely lethal here. No need for Tera, so I'll just focus on the non-Tera approach and keep things concise.
    Claude Haiku 5.5 used Stealthrockautopilot4,482 tok · 13.2 s · $0.0013
    Reasoning trace (222 words)
    Garganacl is at 175/404 facing Ogerpon-Wellspring, which has Water Absorb. Ivy Cudgel changes type based on the mask worn—with the Wellspring Mask it becomes Water-type, so I need to account for that instead of treating it as Grass.
    
    Grass is actually super-effective against Rock, so Garganacl needs to be careful here. At 43% health, I'm weighing whether to Recover or attack; Ground-type moves like Earthquake would hit Ogerpon-Wellspring neutrally since Grass/Water doesn't share a Ground weakness.
    
    Ogerpon is faster than Garganacl, so it gets the first hit with Ivy Cudgel, which with its own boosted effectiveness is doing massive damage, over half of Garganacl's health in one shot. Recovering only buys one extra turn before getting hit again, so I'm now considering switching to Gholdengo instead, since its Steel/Ghost typing isn't weak to Grass.
    
    Switching out gives Ogerpon-Wellspring a free entry, and its Ivy Cudgel is actually Water-typed from the mask, with Water Absorb as its ability. I'm weighing whether Garganacl should Terastallize to Ground to turn that Water hit into something it absorbs instead.
    
    But Ground is actually weak to Water, so that doesn't help at all. The better line is probably switching into Corviknight, which takes Ivy Cudgel neutrally thanks to its Steel/Flying typing and bulky defenses, then threatens back with Brave Bird since Ogerpon-Wellspring is weak to Flying.

    Claude Haiku 5.5 switched to Dragapult3,506 tok · 8.3 s · $0.0008

    Garganacl fainted, so I must switch. Dragapult outspeeds Ogerpon-Wellspring (421 vs 110), and its Choice Specs Dracometeor should hit hard and likely KO it. Ogerpon's Ivy Cudgel is only neutral into Dragapult's bulk, so it can take a hit.

    Reasoning trace (111 words)
    With Garganacl down, I need to switch. Ogerpon-Wellspring resists or absorbs Water with its ability, and I'm working out whether Ivy Cudgel's type shifts to Water with the wellspring mask, which would matter for the matchup.
    
    Checking type matchups for the remaining team: Great Tusk's Ground typing is roughly neutral against Ogerpon-Wellspring's Grass/Water combo since the weaknesses cancel out, while Dragapult's Dragon/Ghost typing isn't hit hard by Ivy Cudgel either.
    
    Dragapult wins the speed race against Ogerpon and can hit it hard with Draco Meteor from Choice Specs given Ogerpon's modest special bulk, while Dragapult itself takes Ivy Cudgel fine and isn't weak to Stealth Rock. I'll go with Dragapult.
    
    
  4. Turn 3
    GPT-6 Luna Pro switched to Kingambit7,807 tok · 7.2 s · $0.0009

    Dragapult is faster than Ogerpon and threatens it before it can act. Kingambit resists its likely Dragon and Ghost attacks, making it the safest switch.

    Reasoning trace (90 words)
    **Analyzing matchups**
    
    I need to pick between Ogerpon and Dragapult. Dragapult has a faster speed stat of 421, likely with a Choice Scarf, while Ogerpon is at 350. I'm considering that Dragapult could threaten with moves like Draco Meteor or Shadow Ball, but what's the best switch? Gholdengo can't take the ghost hit since it's weak to it. However, Kingambit might be a good option since it resists both ghost and dragon moves. Overall, switching to Kingambit seems safest, but I need to think about potential moves from the opponent.
    Claude Haiku 5.5 used Dracometeor3,336 tok · 7.8 s · $0.0007

    Dragapult outspeeds Ogerpon-Wellspring (421 vs 110), and Thunderbolt would be absorbed by Water Absorb. Choice Specs Dracometeor is neutral and 130 BP against an 80 HP, 96 SpD mon, so it should knock it out before it moves. No Tera needed.

    Reasoning trace (73 words)
    Ogerpon-Wellspring is Grass/Water with Water Absorb, so Thunderbolt would do nothing against it, and I need to check how Dragon Meteor interacts with it instead.
    
    Dragon Meteor is neutral against Grass/Water, and with Choice Specs and Dragapult's 299 SpA against Ogerpon's modest 80 HP and 96 SpD, it should comfortably KO. Dragapult also outspeeds Ogerpon by a wide margin, so there's no need to Tera -- Dracometeor alone should finish the job.
    
    
  5. Turn 4
    Claude Haiku 5.5 used Dracometeortera4,060 tok · 10.0 s · $0.0010

    Dragapult outspeeds Kingambit, and Draco Meteor already hit for about 44% earlier. Kingambit is at 50%, so a plain Draco Meteor likely leaves it alive at a few percent. Terastallizing to Dragon gives Draco a 2x STAB boost, which should be enough to secure the knockout.

    Reasoning trace (131 words)
    I'm calculating Dragapult's Choice Specs Draco Meteor damage at -2 SpA against Kingambit, who's at 50 HP, factoring in the Dragon-vs-Steel resistance cutting damage in half.
    
    But if Dragapult Terastallized into Dragon, keeping its Dragon-type as the tera type would boost STAB from 1.5x to 2x, pushing damage up roughly 33% — that extra boost could turn a non-KO into a KO on Kingambit's remaining 50%.
    
    Since Dragapult's speed of 421 far outpaces Kingambit's 50 base speed, I don't need to worry about speed ties, just whether the hit actually finishes it. Tera is a limited resource though, so I'm weighing whether there's a cheaper option like Shadow Ball, checking how Ghost-type moves interact with Kingambit's Dark/Steel typing to see if that alone gets the job done without burning Tera.
    
    
    GPT-6 Luna Pro used Kowtowcleave9,835 tok · 18.6 s · $0.0017

    Kingambit is slower, but Dragapult’s Draco Meteor is weakened at -2 and will not knock it out. Kowtow Cleave is the best chance to finish Dragapult through its resistance to Dark being absent.

    Reasoning trace (76 words)
    **Considering strategy options**
    
    If my opponent switches to Great Tusk, I think using Kowtow is a good option since the opponent may switch. If they use Sucker Punch, it might fail. If the opponent is at low health and I choose Pult Draco, it could avoid the Sucker. Since target attacks may not knock out Pult Draco, I could ensure a knockout by using Kowtow while also surviving the Draco move. It's definitely a tactical choice!
  6. Turn 5
    Claude Haiku 5.5 switched to Landorus3,893 tok · 8.8 s · $0.0009

    Dragapult is locked into Draco Meteor under Choice Specs with -4 SpA, and Dragon is only 0.5x into Steel, so it probably won't finish the 28% Kingambit. Choice Scarf Landorus outspeeds it and Earthquake is 2x on Kingambit's Steel typing. Intimidate also weakens Kowtow Cleave on entry.

    Reasoning trace (138 words)
    Checking the matchup details—Kingambit is Dark/Steel, so Draco Meteor's Dragon-type hit is resisted by Steel, and I'm weighing how Tera Fairy would change its defensive typing against Dark versus Steel-type attacks.
    
    But Dragapult is Choice-locked into Draco Meteor already, so that's the only legal move besides switching, despite Shadow Ball being a theoretically better matchup into Kingambit. With Dragapult sitting at 115 HP and Kingambit threatening a crit Kowtow Cleave, I'm considering whether switching out is safer than staying locked into a resisted Draco Meteor.
    
    Switching to Gholdengo gives a clean 2x Shadow Ball KO on Kingambit's 28% HP, and Landorus with Choice Scarf also KOs via super-effective Earthquake while outspeeding and dropping Kingambit's Attack via Intimidate on the switch-in. Landorus seems like the safest option since Kowtow Cleave hits it neutrally, so I'll switch to Landoran-Therian.
    
    
    GPT-6 Luna Pro used Ironhead9,734 tok · 15.8 s · $0.0015

    Dragapult is faster, but its Draco Meteor is heavily weakened at -4 and resisted by Kingambit. Iron Head is super effective against its Fairy typing and should finish it off.

    Reasoning trace (149 words)
    **Analyzing battle strategies**
    
    I need to make a choice here. Dragapult is at 37%, likely faster due to Fairy Tera, which complicates things. Kingambit's Sucker Punch has priority, but can Dragapult use Draco Meteor? If Kingambit uses Dark moves, Fairy resists those. I need to remember that Sucker Punch can potentially KO Dragapult based on its low health, but it might not be straightforward since Dragapult can strike first. Iron Head is super effective against Fairy, but timing is everything here!**Deciding on moves**
    
    Okay, I’m leaning towards using Iron Head without Tera. I need to factor in a few things to make sure it’s the right choice. There’s definitely a lot to consider in terms of type matchups and damage calculations. I want to ensure I’m making the best play while being cautious about potential counters or effects. It's important to weigh all options carefully before finalizing my decision!

    Claude Haiku 5.5 used Earthquake3,074 tok · 4.3 s · $0.0005

    Landorus-T is much faster than Kingambit (Choice Scarf, 309 Spe vs base 50), and Kingambit is at 28% HP. Earthquake is 2x super effective against Dark/Steel and has 100% accuracy, so it should knock Kingambit out before it moves.

    Reasoning trace (35 words)
    Kingambit is at 28% HP with no Levitate, so Landorus's Earthquake hits for super effective damage against its Dark/Steel typing, and with its scarf speed advantage it should easily outpace and knock it out.
    
    
    GPT-6 Luna Pro switched to Ogerpon8,274 tok · 8.3 s · $0.0010

    Landorus is faster and can likely knock out the weakened Kingambit with Earthquake. Ogerpon resists Ground and threatens Landorus with Ivy Cudgel, making it the safest switch.

    Claude Haiku 5.5 used Earthquake3,268 tok · 6.0 s · $0.0006

    Landorus-Therian with Choice Scarf outspeeds Ogerpon-Wellspring (309 vs 110). Earthquake already did about 37% to it last turn, and it has only 51% left, so it should be knocked out before it can attack. Earthquake is the only attacking option here.

    Reasoning trace (79 words)
    My Landorus is at full health with a choice scarf and high speed, facing an Ogerpon-Wellspring at half HP that has Water Absorb and Ivy Cudgel. Since Ogerpon-Wellspring is Grass/Water, Ground-type Earthquake works out to neutral damage overall since the resistance from Grass cancels the weakness from Water.
    
    Earthquake already took a big chunk off last turn, and with Ogerpon at 51% I should outspeed and use Earthquake again to finish it off or get it very low.
    
    
    GPT-6 Luna Pro used Ivycudgel8,506 tok · 10.0 s · $0.0011

    Ogerpon is faster than Landorus and Ivy Cudgel’s 4× Grass effectiveness should knock it out before it can move. Terastallizing would weaken that matchup, so attack without Tera.

    Reasoning trace (79 words)
    **Comparing Ogerpon and Landorus**
    
    I’m trying to decide between Ogerpon and Landorus. Ogerpon is faster at 350 vs. Landorus at about 309. Ogerpon's Ivy Cudgel is super effective against Landorus's Grass vs. Ground/Flying, likely leading to a knockout at 64%. I wonder if tera transformations are worth considering since Ogerpon's Water-type tera wouldn’t be as effective against Landorus. Also, non-terastallized Grass retains its STAB and could probably OHKO regardless. Speed concerns might play a role in the decision, though.
    Claude Haiku 5.5 switched to Corviknight3,967 tok · 8.8 s · $0.0009

    Ogerpon-Wellspring is at 12% and slower than Corviknight (170 vs 110 Speed). Corviknight resists its Grass-type Ivy Cudgel and can Brave Bird it for a super-effective knockout first. Corviknight is the safest switch-in.

    Reasoning trace (109 words)
    I need to pick the right switch-in against Ogerpon-Wellspring, who's at 12% HP and wielding Ivy Cudgel with Water Absorb active. Considering Great Tusk's typing matchup against this Grass/Water threat.
    
    Gholdengo stands out here: Thunderbolt hits super effectively, and crucially Gholdengo outspeeds Ogerpon by a huge margin (267 vs 110 speed), so it can just finish the opponent off before taking a hit back.
    
    Corviknight is another solid option — Brave Bird hits Ogerpon Wellspring for 2x and Corviknight is faster at 170 speed, while its Flying/Steel typing resists Ivy Cudgel's Grass attack down to 0.5x, making it a safe switch-in that can clean up the low-HP Ogerpon.

    Claude Haiku 5.5 used Bravebird3,008 tok · 4.2 s · $0.0005

    Corviknight outspeeds Ogerpon-Wellspring (170 vs 110), and Ogerpon is at 12% HP. Bravebird is super effective against its Grass typing, so it should knock Ogerpon out before it moves. Water Absorb doesn't matter since Bravebird isn't a Water move.

    Reasoning trace (28 words)
    Corviknight outspeeds Ogerpon, and since Ogerpon-Wellspring is Grass/Water, Brave Bird's Flying typing hits it super effectively on the Grass side, easily finishing it off at 12% HP.
    
    
    GPT-6 Luna Pro switched to Gholdengo8,733 tok · 9.3 s · $0.0011

    Ogerpon is at critical HP and Corviknight resists its main attacks, so staying in is a bad matchup. Gholdengo can pressure Corviknight and prevent Defog if it tries to clear hazards.

    Reasoning trace (151 words)
    **Analyzing matchups**
    
    I’m considering Corviknight's moves like Roost or Brave Bird and the situation with Ogerpon, who is low on HP. I think switching to Gholdengo would block Defog and apply pressure with Make It Rain, but there's risk if Corviknight U-turns. 
    
    While Great Tusk has a poor matchup, Raging Bolt could be a strong play considering its resistances against flying and steel types. Ultimately, switching Gholdengo seems more favorable despite the potential U-turn from Corviknight.**Evaluating type matchups**
    
    I’m thinking about the interactions between Fighting and Steel types. Fighting moves are super effective against Steel, but Steel types have immunity to Ghost moves, which complicates things. I’m considering the possibility of using U-turn as a tactic for switching. Since Fighting is super effective against Steel, I need to keep in mind the immunity of Ghost, which makes switching an important decision here. Balancing these interactions is crucial for a successful strategy.
  10. Turn 9
    Claude Haiku 5.5 switched to Great4,660 tok · 11.3 s · $0.0012

    Brave Bird is resisted by Gholdengo's Steel typing, so Corviknight has no good attack here. Great Tusk switches in safely: Gholdengo's Thunderbolt is immune to Ground, and Tusk is faster. Next turn Headlong Rush is super effective and likely knocks out the 74% Gholdengo.

    Reasoning trace (140 words)
    I'm checking the type matchups between Corviknight and Gholdengo, weighing how Brave Bird and Shadow Ball interact with their Steel/Flying and Steel/Ghost typings respectively.
    
    Great Tusk could work since Ghost is immune to Fighting but Ground still hits Steel for 2x, meaning Headlong Rush would be super effective on Gholdengo. Though switching to Great Tusk means taking a hit first, it seems like a strong option.
    
    U-turn from Corviknight is weak against Gholdengo's Steel/Ghost typing, so Roost to stall or switching into Great Tusk looks better—Great Tusk resists most of Gholdengo's coverage since Electric is immune against Ground, and Shadow Ball/Make It Rain only hit neutrally.
    
    Switching in costs nothing extra, and Great Tusk's Headlong Rush next turn, boosted by Protosynthesis, should be strong enough to KO Gholdengo at roughly 74% health. I'll go with switching in Great Tusk.
    
    
    GPT-6 Luna Pro used Shadowball11,795 tok · 27.4 s · $0.0024

    Gholdengo is faster than Corviknight and Shadow Ball is its strongest reliable neutral hit; Make It Rain is resisted by Corviknight’s Steel typing.

    Reasoning trace (77 words)
    **Analyzing battle strategy**
    
    I'm analyzing Gholdengo's performance against Corviknight. Its steel/ghost typing means it resists flying, taking 66 damage from a 120 BP hit, so it can endure that. "Make it rain" is resisted, but "Shadow Ball" looks like the best option since it does strong damage and could potentially 2HKO. The speed match-up is also a concern; Gholdengo's speed is 293, likely faster than Corviknight. Ultimately, I'll go with "Shadow Ball" for the strongest neutral hit.
    Claude Haiku 5.5 switched to Gholdengo4,499 tok · 13.4 s · $0.0011

    Gholdengo is the best switch-in. It is at full HP, outspeeds the opposing Gholdengo (267 vs 84 base), and can hit it with super-effective Shadow Ball. Corviknight is the alternative, but it is slower and has no strong follow-up here.

    Reasoning trace (230 words)
    I need to pick a switch-in. The opponent has Stealth Rock up on our side, and their Gholdengo is at 74% health. I'm weighing whether our own Gholdengo matches up well against theirs, since Shadow Ball would just be a Ghost-type move hitting our Steel/Ghost typing.
    
    Their Gholdengo is at 74% HP from Stealth Rock. Turning to Corviknight, I note it's Flying/Steel so Ghost-type moves are neutral against it, and Mirror Armor reflects stat drops back at opponents - its high SpD lets it tank Shadow Ball fine, though its own Brave Bird isn't very effective against Gholdengo's typing.
    
    Looking at their remaining team - Gholdengo, Ogerpon at 12%, Kingambit at 28%, Great Tusk, Dragapult, and an unseen Raging Bolt - I'm weighing options against our own Dragapult, who's Tera Fairy now but down to 36% HP, which seems risky to send out. Our own Gholdengo at full health outspeeds theirs significantly, so I'm checking move effectiveness: Make It Rain is only 0.5x against their Steel/Ghost typing, so I'm working through whether Thunderbolt fares any better.
    
    Thunderbolt is neutral against Steel/Ghost, decent but not overwhelming, but Shadow Ball is actually 2x super effective against their Gholdengo since Ghost hits Ghost hard and Steel is neutral. With our Gholdengo faster and their Gholdengo sitting at 74%, Shadow Ball looks like the strongest play, so I'm going with sending in Gholdengo.

    Claude Haiku 5.5 used Shadowball3,732 tok · 7.2 s · $0.0007

    Our Gholdengo has far higher Special Attack (401 vs. their 133 base) and is faster, so it should KO the opposing Gholdengo. Shadow Ball is super effective against their Steel/Ghost typing, while Make It Rain is only neutral and lowers our own Special Attack. Shadow Ball is the stronger choice.

    Reasoning trace (86 words)
    Our Gholdengo is at full health with Air Balloon while the opposing Gholdengo sits around 74%. I'm weighing Make It Rain against their Steel/Ghost typing since Steel-on-Steel isn't effective, though Shadow Ball would just be neutral too.
    
    Actually, Shadow Ball is super effective here since Ghost hits Ghost for 2x, while Steel vs Steel is neutral — so Shadow Ball's effective 160 damage output beats Make It Rain's 120, making it the better choice against their Good as Gold ability which only blocks status anyway.
    
    
    GPT-6 Luna Pro used Shadowball11,211 tok · 19.3 s · $0.0018

    Shadow Ball is super effective against opposing Gholdengo, and Choice Specs makes it our strongest direct pressure. Staying in is preferable to giving its Air Balloon Gholdengo a free turn against Great Tusk.

    Claude Haiku 5.5 switched to Corviknight3,317 tok · 5.8 s · $0.0006

    Gholdengo fainted, so I must switch. Dragapult is at 36% and Dragon/Ghost takes super-effective Shadow Ball, so it would likely die immediately. Corviknight is at full HP with Leftovers, takes only neutral Ghost damage, and can pressure Gholdengo with Brave Bird or Roost.

    My Gholdengo fainted, so I need to switch to either Corviknight (full HP, Mirror Armor, Leftovers) or Dragapult (36%, Tera Fairy, specs). The opposing Gholdengo sits at 74%, and I'm checking whether Corviknight's Flying/Steel typing resists Ghost—it doesn't, since Ghost hits Steel neutrally.

    Raging Bolt is the best matchup into Corviknight and can threaten a knockout with Thunderbolt. Switching out also avoids leaving Choice-locked Gholdengo in against it.

    Reasoning trace (76 words)
    **Evaluating battle strategies**
    
    I'm considering whether a Flamethrower will likely get a knockout. Corviknight is at full health, and a Scarf Dragapult’s 90 BP super-effective hit might only do about 70%, which isn't a KO. On the other hand, Raging Bolt’s Thunderbolt, with its 410 Special Attack, should easily knock it out. But there's a chance Corviknight could use Brave Bird on the switch first. So, I think Thunderbolt is my strongest and safest option here!
    Claude Haiku 5.5 used Bravebirdautopilot4,805 tok · 12.2 s · $0.0013
    Reasoning trace (170 words)
    I'm checking matchup math: Corviknight at full HP against Gholdengo at 74%, noting Gholdengo's Steel/Ghost typing resists Brave Bird and its Good as Gold ability blocks status moves, while its Shadow Ball hits Corviknight neutrally since Ghost isn't resisted by Steel/Flying.
    
    U-turn would also be resisted, so pivoting to Dragapult at 36% HP makes more sense—with Choice Specs and Tera Fairy, its Fairy-type coverage would hit Gholdengo super effectively, while Draco Meteor stays neutral and Shadow Ball would actually be super effective if I tera into Ghost instead.
    
    Weighing Corviknight's defensive matchup: as Steel/Flying it resists Gholdengo's Steel attacks at 0.5x, so I'm considering Roost to stay healthy rather than committing to an attack this turn.
    
    Brave Bird seems like Corviknight's best damage option against Gholdengo despite the resistance, since my team is down to just Dragapult at 36% and a full-health Corviknight against their Ogerpon, Kingambit, Gholdengo and unknown mons that could include something scary like Raging Bolt.
    
    Brave Bird has no accuracy concerns, so that's the choice.

    Corviknight is our only healthy Pokémon, and Gholdengo at 74% can't be ko'd by Brave Bird alone, but it deals the most damage. Gholdengo resists Flying, so the hit is reduced, yet it still takes roughly half its HP. Dragapult at 36% would just die to Shadow Ball, so switching gains nothing.

    Our Corviknight is at full health against a Raging Bolt sitting at 73% with Booster Energy active under protosynthesis. Raging Bolt hits hard on the special side, while Corviknight leans physically bulky, so I'm weighing whether Corviknight's Flying/Steel typing holds up against Electric-based attacks like Thunderclap or Dragon Pulse given the double weakness there.
    
    I'm sorting through type matchups - Electric hits Corviknight for 2x since Flying is weak to it even though Steel resists, and Raging Bolt's priority Thunderclap is a concern. On the offensive side, Brave Bird from Corviknight against Electric/Dragon should actually be neutral damage, so I'm estimating the rough damage output at 120 base power with Corviknight's 210 attack against Raging Bolt's 91 defense and remaining HP.
    
    Now I'm weighing whether to U-turn into Dragapult instead - its Tera Fairy typing would make it immune to Raging Bolt's Dragon STAB while still taking only neutral Electric damage, and its Choice Specs Draco Meteor could hit back hard, but Dragapult's low HP makes me nervous about Thunderclap picking it off first.
    
    If Corviknight stays in, I'm estimating Thunderbolt would deal roughly 40-50% given its SpD, leaving it able to tank one hit and fire back with Brave Bird again, though I'm second-guessing my earlier damage math on how much the first Brave Bird actually took off Raging Bolt's HP.
    
    For the Dragapult switch scenario, a Specs-boosted Dracometeor would hit incredibly hard on the Dragon-type Raging Bolt, likely 70%+, and since Dragapult outspeeds it goes first — but Dragapult also eats stealth rock damage on entry which could set it up to die afterward to a retaliating hit.

    Thunderbolt is the deciding play: Corviknight is weak to Electric, and Raging Bolt can hit it hard before the slower Corviknight moves. Thunderclap risks failing if Corviknight doesn’t attack, while Thunderbolt gives reliable damage.

    **Choosing thunderbolt strategy**
    
    I need to consider using Thunderbolt, especially since Corviknight is weak to Electric moves. It's important to think about how much damage Thunderbolt will do; it could potentially score a knockout with a strong special attack. The opponent has already terastallized their Dragapult, which might impact the Corviknight matchup. Overall, it seems like Thunderbolt is the best choice since it can hit hard and may lead to a quick victory before Corviknight can strike back.

    Corviknight has fainted, so the only legal action is switching in Dragapult. It is the sole option, so I pick it.

    Dragapult is faster (421 Speed) than Raging Bolt, so it moves first. Dracometeor is Dragon STAB with Choice Specs and hits Raging Bolt's Dragon typing for 2x, which should KO the 73% Raging Bolt. Thunderbolt is resisted by Electric/Dragon, so it's the wrong move.

    I'm working out the matchup details: Dragapult with Tera Fairy and Choice Specs against a Raging Bolt at 73% HP with Booster Energy active. I'm checking whether Tera Fairy actually removes Dragapult's Dragon weakness or just changes its STAB typing, since Raging Bolt is Electric/Dragon.
    
    Dragon STAB on Dracometeor is retained since Dragapult's original type still gets the boost, and Dragon vs Dragon is super effective on Raging Bolt while Electric is neutral, giving a clean 2x multiplier. With Choice Specs amplifying the 130 BP Dracometeor against a 73% HP Raging Bolt, and Dragapult's massive speed advantage, I'm leaning toward this being a likely KO.
    
    Checking alternatives like Thunderbolt confirms it's resisted (Electric/Dragon takes only 0.25x from Electric), so it's clearly inferior. Dracometeor is the best option despite the Specs lock-in risk and accuracy concerns.

    Dragapult is faster, but Thunderclap’s priority lets Raging Bolt strike first. At 37% HP, Terastallized Thunderclap is the safest way to secure the knockout.

    **Evaluating battle options**
    
    I need to choose between Raging Bolt and Fairy Tera Dragapult, which is at 37% health. Thunderbolt is likely to do significant damage, though Dragapult is probably faster. If it uses Draco Meteor, that won’t work since Fairy Tera is immune to Dragon moves. Thunderclap has priority, which is great for securing a KO, especially considering Dragapult’s low health. Raging Bolt's Thunderclap should be effective given its power and the STAB factor, though I’m weighing all the calculations!**Deciding on Tera strategy**
    
    Raging Bolt’s Tera Electric boosts damage to 2x, but maybe I don’t need it for a guaranteed KO. If the opponent has already used their Tera, then utilizing Thunderclap in Tera form definitely secures a knockout. However, without Tera, Thunderclap might only deal about 33-39% damage to Dragapult at 37% health, which is uncertain. I’m leaning toward going for the Tera Thunderclap to ensure the knockout, but I should keep speed in mind too!
