How would Magneton with Spark/DC against Kyogre?
When someone else asked about counters to Blizzard Kyogre, I replied "Magneton with Spark/Discharge and Ludicolo with RL/Solar". That was intended as a joke and got downvoted.
However, I do have a level 30 Magneton with Spark/DC, which destroyed many Gyaradoses under the old system. As I have only one Raikou and no Zapdos (was on hiatus then), I genuinely wonder how Magneton would fare against Kyogre.
Not just Blizzard; Magneton is also resistant to DT and Thunder. Changi Village also spawns Magnemites by the dozen (unless weather has messed that up too) so I could make trips there to farm high-level wonders if I wanted.

PokeBattler has Kyogre's predicted nerfed stats.
Against unknown moveset with rain, Magneton is 6th -- behind Raikou, Zapdos, Jolteon, Sceptile, and Venusaur.
Against unknown moveset with clear skies, Ludicolo is 12th -- behind (among others) Shiftry, Meganium, and Vileplume.
They are not the best choices, but with the right weather can be okay.
