0565 Carracosta

Water Gun has solid damage and energy generation, and lets you deal super effective damage to things like Stunfisk. Rock Throw trades in some of that energy generation for a ton of fast move pressure, which can be incredibly useful in some matchups. No matter which fast move you run, you'll want to run Body Slam and Surf. Not only are they solid moves in a vacuum, they're also not Ancient Power (which is a bad move.). Liquidation is largely redundant since Carracosta already gets Surf.

Running Rock Throw, Carracosta is a perfectly serviceable anti-Flying attacker, though it's outclassed by the other common anti-Flyings. Running Water Gun, it's instead outclassed by the ubiquitous Water-types in the format! No matter what, Carracosta isn't great, though it's certainly not the worst thing you could be running. Just keep it far, far away from...a lot of things, honestly. Water-types, Grass-types, Ground-types, etc.

Carracosta is kinda alright in the Ultra League. You will definitely want to run Rock Throw over Water Gun here, as the coverage is much more valuable. That said, though, there are so many ubiquitous Pokémon that can beat Carracosta without trying, it's a very risky mon to bring out.
