0171 Lanturn

Spark and Water Gun are both perfectly viable fast moves. Spark is generally preferred because it has the same DPT as Water Gun while offering superior EPT. However, Water Gun can find uses when Water coverage is desirable.

The addition of Surf following the September 2022 update is a massive improvement for Lanturn, giving it much more speed in its moveset. Thunderbolt is a generally solid Electric-type attack, with a moderate energy cost. Thunder is largely worse than Thunderbolt, so you can skip out on this one. Hydro Pump is no longer considered due to its massive energy demands. 

Lanturn features an interesting Water/Electric typing, good bulk, and a fairly speedy moveset.These qualities allow Lanturn to be extremely oppressive against Water- and Flying-type Pokemon, strongly countering Pokemon such as Azumarill, Pelipper, Skarmory, and Noctowl. It is also unique amongst Electric-type Pokemon in both said bulk and ability to pressure Galarian Stunfisk. This ability to go toe to toe against Ground-type Pokemon leaves the Grass-type as Lanturn's sole true nemesis, which is generally not difficult to cover.

Candy XL helps boost Lanturn to near the CP cap of Ultra League, though it still falls short. Nonetheless, a faster moveset with Surf allows Lanturn to perform surprisingly well against the overall meta, given its disadvantaged stats. 

Lanturn has swam too far upstream, best turn back to the Great League.
