   GPT-OSS 20B brought Rotomwash,garchomp,blastoise3,929 tok · 32.2 s

   Rotomwash’s high speed and strong special moves give a great first‑move advantage, and it can threaten Steelix with Thunderbolt. Garchomp’s 169 speed and powerful Earthquake/Dragonclaw let it handle Rotomwash and Gengar, while Blastoise’s IceBeam can KO Rotomwash and its high HP keeps it safe. This trio covers the main threats and gives us a strong offensive presence.

   Reasoning trace (1,273 words)

   We need to choose 3 Pokémon to bring. We need to consider opponent's team preview. We have 6 Pokémon: rotomwash, toxapex, garchomp, blastoise, gengar, steelix. We need to pick 3 to bring. We need to consider matchups.
   
   Opponent's team: same set of 6? It lists same species: rotomwash, toxapex, garchomp, blastoise, gengar, steelix. So it's symmetrical. We need to choose 3 that give best advantage.
   
   We need to consider speed, type coverage, synergy. We have to pick 3 that are strong against opponent's likely lineup. Since it's symmetrical, we can pick any 3. But we need to consider that opponent will also pick 3. We want to maximize advantage.
   
   We need to consider that we have a strong rotomwash with high speed 151, good special moves. Toxapex is very defensive, good at setting up toxic spikes. Garchomp is powerful physical, high speed 169. Blastoise is solid special, good with icebeam. Gengar is special with high speed 178. Steelix is bulky.
   
   We need to consider that opponent will likely pick a balanced team. We need to pick a team that can handle all.
   
   We might want to bring rotomwash, gengar, and garchomp. Rotomwash can set rain with raindance, but we don't have rain. But we can use thunderbolt, hydropump. Gengar can handle Steelix, blastoise, etc. Garchomp can handle rotomwash, etc. But we need to consider that opponent might bring rotomwash, gengar, steelix. We need to counter them.
   
   Alternatively, bring rotomwash, blastoise, gengar. Rotomwash can handle steelix with thunderbolt? Steelix is Steel/Ground, weak to electric. Rotomwash can use thunderbolt. Gengar can handle steelix with shadowball. Blastoise can handle rotomwash with icebeam? Rotomwash is Electric/Water, weak to ice. So blastoise can use icebeam to KO rotomwash. But rotomwash has high speed and can use thunderbolt. But if we bring blastoise, we can use icebeam to KO rotomwash. But rotomwash might use thunderbolt on blastoise? Blastoise is water, not weak to electric. So safe.
   
   But we need to consider that opponent might bring rotomwash, blastoise, gengar. We need to counter them. Rotomwash vs blastoise: rotomwash can use thunderbolt, but blastoise is water, not weak to electric. But rotomwash can use hydropump, but blastoise is water, not weak to water. So rotomwash might struggle. But we can use thunderbolt to damage blastoise. But blastoise has high HP and defense. But we can use hydropump to damage rotomwash. But rotomwash is 151 speed, blastoise 98. So rotomwash will move first. But we can use thunderbolt to damage blastoise. But blastoise can use icebeam to damage rotomwash. So it's a trade.
   
   Alternatively, bring rotomwash, gengar, steelix. Rotomwash can handle steelix with thunderbolt. Gengar can handle rotomwash with shadowball. Steelix can handle gengar with ironhead? Gengar is ghost/poison, steel is weak to ghost? Steel is 2x weak to ghost? Actually ghost is neutral to steel. Gengar is ghost/poison, steel is 2x weak to ghost? Wait ghost vs steel: ghost is neutral to steel. So steelix is not weak to ghost. But steelix is weak to fire, rock, ice. Gengar is ghost/poison, so not super effective. But steelix can use ironhead to damage Gengar? Gengar is ghost/poison, ironhead is steel, so neutral. So steelix may not be good.
   
   Alternatively, bring rotomwash, blastoise, steelix. Rotomwash can handle steelix with thunderbolt. Steelix can handle blastoise? Steelix is ground/steel, blastoise is water, so steelix is 2x weak to water. So steelix will be weak. But steelix can use stoneedge to damage blastoise? Stoneedge is rock, blastoise is water, so neutral. But steelix can use ironhead to damage blastoise? Ironhead is steel, blastoise is water, neutral. So steelix is not good.
   
   Alternatively, bring rotomwash, gengar, blastoise. Rotomwash can handle steelix, blastoise can handle rotomwash, gengar can handle steelix? Gengar is ghost/poison, steel is neutral. But gengar can handle blastoise? Blastoise is water, gengar is ghost/poison, so neutral. But gengar can handle rotomwash? Rotomwash is electric/water, ghost is neutral. So not super effective. But we can use focusblast? Gengar has focusblast, but it's fighting. But not super effective.
   
   Alternatively, bring rotomwash, gengar, toxapex. Toxapex can set toxic spikes, can handle steelix? Steelix is ground/steel, toxic spikes will poison steelix. But steelix has high defense. But toxapex can use banefulbunker to protect. But we need to consider that opponent might bring rotomwash, blastoise, gengar. Toxapex can set toxic spikes to damage blastoise and gengar. But blastoise is water, not weak to poison. But toxapex can use recover. But we need to consider that we might get stuck.
   
   Alternatively, bring rotomwash, garchomp, blastoise. Rotomwash can handle steelix, garchomp can handle rotomwash, blastoise can handle rotomwash. But we need to consider that opponent might bring rotomwash, blastoise, gengar. Rotomwash vs blastoise trade. Garchomp vs gengar: Garchomp is dragon/ground, gengar is ghost/poison, neutral. Garchomp can use dragonclaw to damage gengar. But gengar can use shadowball to damage garchomp? Garchomp is dragon/ground, ghost is neutral. So not super effective. So garchomp can handle gengar. So this team might be good.

   GPT-OSS 20B used Hydropump3,476 tok · 32.1 s

   Steelix is 4× weak to Water, so a Hydropump will do massive damage. It’s also slower than Rotom‑Wash, so we can safely hit first. No need to switch or set rain yet.

   Reasoning trace (1,328 words)

   We need to decide best action. Rotom-Wash vs Steelix. Steelix is Steel/Ground, so it's 4x weak to Water? Steelix is Steel/Ground: Water is super effective? Water vs Steel is 2x, vs Ground 2x, so 4x. So Hydropump is super effective. Rotom-Wash has 127 HP, Steelix unknown HP but likely 150-182. Hydropump 110 power, 80% accuracy. Could KO? Let's estimate: Rotom-Wash has 141 SpA, Steelix has maybe 67-117 SpD. Damage formula: (2*50/5+2)*110*141/SpD / 50 + 2. Let's approximate with SpD 100: (2*50/5+2)= (20+2)=22. 22*110=2420. 2420*141=341,220. /100=3,412.2. /50=68.24. +2=70.24. So about 70 damage. Steelix HP maybe 150-180, so 70 damage not KO. But it's super effective, so maybe 140 damage? Wait we used SpD 100. If SpD 80, damage higher. But still not KO. But we can use Voltswitch to switch out after damaging. But we might want to set up rain with Raindance? But Steelix is not Water. Rotom-Wash can set rain to boost Hydropump. But we only have 5 turns. But we might want to use Hydropump to damage and maybe set rain for later. But we also might want to switch to a better matchup. Rotom-Wash has 151 speed, so first. Steelix is slower. We can use Hydropump to damage. But we might want to use Voltswitch to switch to Garchomp or Blastoise. Garchomp is Dragon/Ground, Steelix is Ground, so Garchomp is 4x weak to Electric? Actually Garchomp is Dragon/Ground, so Electric is 4x super effective. But Steelix is Ground, so Garchomp is 4x weak to Electric. But Steelix is Ground, so Garchomp is 4x weak to Electric. But Steelix is not Electric. So Garchomp would be good vs Steelix? Wait Steelix is Steel/Ground. Garchomp is Dragon/Ground. So Steelix is 2x weak to Dragon? Actually Steel is 2x weak to Dragon? No, Steel is 2x weak to Dragon? Wait type chart: Dragon is 2x weak to Dragon? No. Dragon is 2x weak to Dragon? No. Dragon is 2x weak to Dragon? No. Dragon is 2x weak to Dragon? I'm mixing.

   Rotom is faster but Gengar’s high SpA could KO it. Switching to Garchomp gives a safe, faster matchup that can survive Gengar’s attacks and set hazards if needed.

   Reasoning trace (1,206 words)

   We need to decide best action. Rotom-Wash vs Gengar. Rotom has 127 HP. Gengar unknown HP 135-167. Rotom's moves: Hydropump 110, Thunderbolt 90, Voltswitch 70, Raindance. Gengar is Ghost/Poison, immune to Electric? Ghost/Poison: Electric is not super effective; Water is neutral. Gengar has high SpA 135-200, SpD 85-139, Speed 117-178. Rotom has high Speed 151. So Rotom likely moves first. Gengar's moves unknown but likely something like Shadow Ball or Sludge Bomb. Rotom's Hydropump 110 deals neutral damage. Gengar's SpA high, but Rotom has 127 HP. Gengar's potential damage: Shadow Ball 80, Sludge Bomb 75. But Gengar's SpA 135-200, so damage could be high. Rotom's HP 127, Gengar's HP unknown 135-167. Rotom could potentially KO Gengar with Hydropump? Let's estimate: Rotom's SpA 141, Gengar's SpD 85-139. So damage ~ 110 * (141/SpD). If SpD 85, damage ~ 110 * 141/85 = 182. So likely KO. If SpD 139, damage ~ 110 * 141/139 = 111. So maybe not KO. But Gengar's HP 135-167. So Hydropump might not always KO. But we can use Thunderbolt 90, but Electric is not super effective. So Hydropump is best. Also we can consider Voltswitch to switch out to Garchomp or Blastoise. But we want to keep Rotom to continue. Gengar might have a strong move like Shadow Ball that could KO Rotom? Rotom has 127 HP, Gengar's Shadow Ball 80, SpA 135-200, Rotom's SpD 127. Damage ~ 80 * 135/127 = 85. So not KO. But Gengar's SpA 200, damage ~ 80 * 200/127 = 126. So could KO Rotom. So Gengar could potentially KO Rotom. But Rotom can survive one Shadow Ball. But if Gengar uses something like Sludge Bomb 75, damage ~ 75 * 200/127 = 118. So could KO Rotom. So Rotom is at risk. But we can use Voltswitch to switch to a more defensive or better matchup. Garchomp is Dragon/Ground, immune to Electric, but Gengar is Ghost/Poison, so Garchomp would be 4x weak to Poison? Garchomp's type: Dragon/Ground. Poison is not super effective. Gengar is Ghost/Poison. Garchomp's SpA 90, SpD 105, Speed 169. Gengar's SpA 135-200, SpD 85-139. Garchomp's HP 185. Gengar's moves could be Shadow Ball 80, Sludge Bomb 75. Garchomp's HP 185, so can survive. But Garchomp is 4x weak to Fighting? Not relevant. Garchomp's Ground immunity to Electric, but Gengar is not Electric. So Garchomp could survive. But Garchomp's speed 169 > Gengar's 117-178. So Garchomp would move first. Garchomp's moves: Earthquake 100, Dragon Claw 80, Swords Dance, Stealth Rock. Gengar's moves unknown. Garchomp could use Earthquake 100 vs Gengar's HP 135-167. Earthquake is Ground, Gengar is Ghost/Poison, so neutral. Damage ~ 100 * 90/SpD. Gengar's SpD 85-139. So damage ~ 100 * 90/85 = 106. If SpD 139, damage ~ 100 * 90/139 = 65. So Garchomp might not KO. But Garchomp could use Dragon Claw 80. So maybe not. But Garchomp could set Stealth Rock. But we might want to keep Rotom. Rotom is good for water moves. Gengar is a threat. But we can also use Raindance to set rain, boosting water moves. But we only have 5 turns. But we might want to keep Rotom for future. But we can also switch to Blastoise. Blastoise has high HP 186, high SpA 150, SpD 127, Speed 98. Gengar's moves might be 80-90. Blastoise can survive. But Blastoise's speed 98 < Gengar's 117-178, so Gengar moves first. But Blastoise can use Hydropump 110. That might KO Gengar. But Gengar might use Shadow Ball 80. Damage ~ 80 * 135/127 = 85. So Blastoise can survive. So switching to Blastoise is safe. But we might want to keep Rotom for future. But Rotom is at risk of being KO by Gengar's high SpA. But we can use Voltswitch to switch out and keep Rotom. But we might want to use Voltswitch to switch to Garchomp or Blastoise. But we need to decide best action. The instruction: choose single best action. We need to consider speed, likely knockout, or bad matchup to switch out. Rotom vs Gengar: Rotom is faster, but Gengar might KO Rotom with high SpA. But Rotom can KO Gengar with Hydropump? Not guaranteed. But we can use Voltswitch to switch to a better matchup. Garchomp is 4x weak to Poison? Actually Poison is not super effective on Dragon/Ground. So Garchomp is fine. But Garchomp's speed 169 > Gengar's 117-178. So Garchomp will move first. Garchomp's Earthquake 100 vs Gengar's HP 135-167. Might not KO. But Garchomp can use Dragon Claw 80. So Garchomp might survive. But Garchomp's HP 185, so can survive. But Garchomp might set Stealth Rock. But Gengar might use something like Shadow Ball 80. Garchomp's SpD 105, damage ~ 80 * 135/105 = 103. So Garchomp might survive. So Garchomp is safe. But Garchomp's speed 169 > Gengar's 117-178. So Garchomp moves first. But Garchomp's Earthquake 100 vs Gengar's HP 135-167. Might not KO. But Garchomp can use Dragon Claw 80.

But we can use Voltswitch to switch out. But we might want to use Hydropump to try to KO Gengar. But if Gengar is high HP, we might not KO. But we might want to use Thunderbolt to try to paralyze Gengar. But Gengar is not Electric type. But we might want to use Raindance to set rain. But we only have 5 turns. But we might want to use Raindance to boost water moves. But we might want to use Voltswitch to switch to Garchomp or Blastoise. The best action might be Voltswitch to switch to Garchomp or Blastoise. But we need to choose one action. The instruction: "Choose exactly one action from LEGAL ACTIONS." So we can choose Voltswitch. But we need to decide which switch. The action is "SWITCH: garchomp" or "SWITCH: blastoise". We need to pick one. Which is better? Rotom vs Gengar: Rotom is at risk of being KO by Gengar's high SpA. But we can switch to Garchomp. Garchomp is 4x weak to Poison? Actually Poison is not super effective on Dragon/Ground. So Garchomp is safe. Garchomp's speed 169 > Gengar's 117-178. So Garchomp will move first. Garchomp's Earthquake 100 vs Gengar's HP 135-167. Might not KO. But Garchomp can use Dragon Claw 80. So Garchomp might survive. But Garchomp's HP 185, so can survive.

   Blastoise is a Water‑type, so Ground moves are super effective. Mega‑evolving Garchomp boosts its Attack and Speed, ensuring a KO with Earthquake before Blastoise can react. No better switch or status move exists this turn.

   Reasoning trace (152 words)

   We need to decide best action. Garchomp vs Blastoise. Garchomp has 100% HP. Blastoise unknown item, unknown ability. Likely has Water-type moves. Garchomp is Ground/Dragon. Ground is super effective vs Water. So Garchomp can KO with Earthquake. Also Garchomp can Mega Evolve to Mega Garchomp, boosting Attack and Speed. That would increase damage. Also Earthquake is 100 power, but Mega Garchomp Attack is 210? Actually base Attack 182, Mega boost to 210? Wait Garchomp's Attack is 182, Mega boost to 210? Actually Mega Garchomp Attack is 210. So damage increases. Also speed increases to 190? Actually Mega Garchomp Speed 190. So still faster. So best action: Mega Earthquake. That will likely KO Blastoise. So choose MOVE: earthquake [MEGA].
   
   We need to consider if Blastoise might have ability Torrent, boosting Water attacks. But Earthquake is Ground, unaffected. So no problem.
   
   Thus decision: MOVE: earthquake [MEGA].

We have bench: rotomwash and blastoise. Rotomwash is 127 HP, Electric/Water, with Hydropump, Thunderbolt, Voltswitch, Raindance. Blastoise on bench is 186 HP, but we already have active Blastoise? Wait opponent active is Blastoise. Our bench has a Blastoise too. That is a different Pokemon. So we can switch to either. We want to avoid being frozen again? Rotomwash is not frozen. But we might want to use Rotomwash to set up rain? But we have no rain. Rotomwash can use Voltswitch to switch out and set up rain? Actually Voltswitch is Electric/Status? It's Electric/Status?

   Anyway, we need to switch. Which is best? Rotomwash has high speed 151, can set rain with Raindance. But we don't need rain. But we might want to use Voltswitch to switch out again? But we are already switching. We could switch to Rotomwash to have a fast Electric/Water that can threaten Blastoise with Thunderbolt (super effective). But Blastoise is Water, so Thunderbolt is not super effective, it's 0.5x. But Hydropump is super effective. Rotomwash can use Hydropump to KO Blastoise. But we might want to use Voltswitch to set rain? But we don't need rain. Rotomwash can also use Voltswitch to switch again to something else? But we only have two bench.
   
   Alternatively switch to Blastoise on bench. That gives us a Water type with high HP 186, but slower. But we might want to use it to set up hazards? But we don't have hazards. But we might want to use it to use Ice Beam? But we don't have Ice Beam. But we can use it to use something else? But we don't have moves listed. But we can use it to use something like Hydro Pump? But we don't know its moves. But we can use it to use something like Ice Beam? But we don't know. But we can use it to use something like something else. But we don't know.
   
   Given that Rotomwash has high speed and can KO Blastoise with Hydropump, that seems best. So we should switch to Rotomwash. The decision: SWITCH: rotomwash.

   GPT-OSS 20B used Thunderbolt2,566 tok · 16.8 s

   Thunderbolt is super‑effective, 100% accurate, and has a high chance to KO the weakened Blastoise. Rotom‑Wash’s speed advantage means it can strike first unless Blastoise is maxed. Voltswitch would lose the advantage of staying on the field, and switching to Blastoise pits two Water types with unknown moves. Likely knockout is the deciding factor.

   We need to decide best action. Rotom-Wash vs Blastoise Mega. Rotom-Wash has Water and Electric moves. Blastoise is Water type, but has IceBeam and RapidSpin. Blastoise has ability Megalauncher, boosting pulse moves. Rotom-Wash's Water moves are not pulse moves, so no boost. Rotom-Wash's Electric moves are super effective. Rotom-Wash's speed 151 vs Blastoise 132-214. Blastoise could be faster if it has high speed investment. But Rotom-Wash has high speed 151, so likely faster unless Blastoise has max speed 214. But we don't know. Rotom-Wash can use Thunderbolt (90 power, 100% accuracy, 10% paralyze). That would do 90*1.5? Wait, no boost. So 90. Rotom-Wash's Water moves are not super effective. So Thunderbolt is best. But we also have Voltswitch: 70 power, 100% accuracy, super effective, and switches out after damaging. Rotom-Wash has 116/127 HP, not low. But we might want to keep Rotom-Wash to use Thunderbolt. But maybe we want to switch to GarchompMega? GarchompMega is 2.7% HP, so it's faint. That would be a bad switch. Switch to Blastoise? That would bring opponent's Blastoise onto our side? Wait, we can switch to Blastoise? That would bring our Blastoise onto the field, but opponent's active is Blastoise. So switching to Blastoise would cause a clash? Actually, you cannot switch to opponent's Pokémon. The SWITCH action is to switch to a Pokémon on your bench. So we can switch to our own Blastoise. That would bring our Blastoise onto the field, and opponent's active would be replaced by our Blastoise? Wait, in Pokémon, you can switch your active Pokémon with one on your bench. So if we switch to our Blastoise, our Blastoise becomes active, and opponent's active remains the same. So we would have our Blastoise active vs opponent's Blastoise. That seems like a bad matchup: both are Water type, but our Blastoise is 186/186 HP, but we don't know its moves. But we don't know its moves. But we know opponent's Blastoise has IceBeam and RapidSpin. Our Blastoise might have moves like Hydro Pump, etc. But we don't know. But we might want to keep Rotom-Wash to use Thunderbolt. So best action: MOVE: thunderbolt.
   
   But we also consider that Rotom-Wash has 116/127 HP, not low. But we might want to use Voltswitch to switch to GarchompMega? But GarchompMega is faint. So no.
   
   Thus best action: Thunderbolt.
   
   We need to produce <thought> and <decision>.
   
   We must keep <thought> 2-4 short sentences, 80 words max. Name deciding factor: speed, likely knockout, or bad matchup to switch out of.
   
   So: "Rotom-Wash is faster than Blastoise unless it has max speed, but Thunderbolt is super effective and has 100% accuracy. It also has a chance to paralyze. Voltswitch would lose the advantage of staying on the field. Switching to Blastoise would pit two Water types against each other with unknown moves." That's 3 sentences, okay.
   
   We must name deciding factor: speed? Actually, speed is a factor. So we can say "Speed advantage" or "likely knockout". Thunderbolt is likely to KO? Let's calculate: Rotom-Wash's Thunderbolt 90 power, opponent's HP 41% of 154-186 => 63-76 HP. 90 damage would likely KO. So likely knockout. So we can say "likely knockout".
   
   Thus <thought>:
   
   "Thunderbolt is super effective and has 100% accuracy, giving a high chance to KO the weakened Blastoise. Rotom-Wash's speed advantage means it can strike first unless Blastoise is maxed. Voltswitch would lose the advantage of staying on the field. Switching to Blastoise would pit two Water types with unknown moves."
   
   We need to name deciding factor: "likely knockout". So we can say "likely knockout".
   
   We need to keep <thought> 2-4 short sentences. Let's do 3 sentences.
   
   Now <decision> must contain exactly one action line: "MOVE: thunderbolt".
   
   Let's produce.

   Gengar is at 36 % HP (≈ 50 HP). A Hydropump (110 power) will almost certainly KO it, and Rotom is faster than Gengar, so it can strike first. No better move or switch is needed.

   We need to decide best action. Rotom-Wash vs Gengar. Rotom has 123/127 HP. Gengar is 36% HP, so about 50-60 HP. Gengar is Ghost/Poison, has high speed, but Rotom is faster (151 vs 117-178). Rotom can use Thunderbolt (90) or Hydropump (110). Gengar has no known moves yet. Rotom can also switch out. Gengar is at 36% HP, so maybe we can KO it with Hydropump? Let's estimate: Rotom's special attack 141, Gengar's HP range 135-167. Hydropump 110 power, 80% accuracy. Damage formula: ((2*level/5+2)*power*SpA/SpD)/50+2. Rotom's SpA 141, Gengar's SpD maybe 85-139. Let's approximate SpD 100. So damage ~ ((2*50/5+2)=22)*110*141/100/50+2 = 22*110*1.41/50+2 = 22*155.1/50+2 = 3412.2/50+2 = 68.24+2=70.24. So about 70 damage. Gengar HP maybe 60. So Hydropump would KO. Thunderbolt 90 power, 100% accuracy. Damage: 22*90*141/100/50+2 = 22*127.0/50+2=2794/50+2=55.88+2=57.88. So about 58 damage. Might not KO. But Gengar has 36% HP, maybe 50 HP. So Hydropump likely KO. But Gengar has high speed, but Rotom is faster. So we can KO. However, Gengar might have a move that could damage Rotom. But we don't know. But we can KO. So best action: Hydropump. Also we could use Voltswitch to switch out after damaging. But we want to finish Gengar. So Hydropump. Also we could use Thunderbolt to paralyze, but not needed. So answer: Hydropump.

   Rotom‑Wash is faster and can finish the Mega Blastoise with a single Thunderbolt, which is super‑effective and has a chance to paralyze. It’s a likely knockout before the opponent can act.

   Reasoning trace (206 words)

   We need to decide best action. Rotomwash is 42/127 HP, poisoned. Opponent is Blastoise-Mega with 41% HP. Rotomwash has 151 speed, so moves first. We want to KO. Hydropump 110 power, but not very effective on Water. But Blastoise-Mega has high defense, but still 110 * 1.5 from Mega Launch? Wait, Mega Launch is ability of Blastoise-Mega: "This Pokemon's pulse moves have 1.5x power." That applies to the opponent's pulse moves, not to Rotom's. So no effect. So Hydropump is 110, not very effective on Water, so 110 * 0.5 = 55 damage. Blastoise-Mega HP 41% of max 154-186. Let's approximate 170 HP. 55 damage is about 32% of HP. Not enough to KO. Thunderbolt 90, super effective on Water, 2x damage, so 180 damage. That would likely KO. Also 10% chance to paralyze. Voltswitch 70, super effective, 140 damage, but Rotom would switch out. That might be good if we want to preserve Rotom. But we might want to KO. Rotom is poisoned, but we can heal with Leftovers. But we might want to finish quickly. Thunderbolt is best. Also we could use raindance but that would not finish. So best action: Thunderbolt.
   
   Thus <thought> speed advantage, Thunderbolt super effective, likely KO. <decision> MOVE: thunderbolt.
