Does Huntail get Shell Break too? Because it's a perfect candidate for a Mixed Rain Sweeper and better than Gorebyss in my eyes c;
Gorebyss is better than Huntail (generally) because it deals more damage to every single Pokemon in the game with the exception of Pokemon like Roserade and Blissey (Pokes that have WAYYY more Special Defense than physical defense).
Here, Gorebyss hits a Poke with WAY higher special defense than physical defense and still out-damages Huntail:
Gorebyss: +2 252 SpA Modest Hydro Pump vs. 252 HP/252 SpD Calm Suicune: 61.6% - 72.8%
Huntail: +2 252 Atk Adamant Aqua Tail vs. 252 HP/252 SpD Calm Suicune: 58.7% - 69.3%
By and large, Gorebyss' attacking prowess will outclass Huntail's. Gorebyss does not even have to go mixed as it is already able to OHKO Blissey. Huntail can work as a mixed sweeper,
I guess, but its only real purpose would be to guarantee the OHKO on Blissey (and generally this is not worth it, since you are now unable to KO Pokemon like Celebi and Gyarados).
Anyway, these EVs (on Gorebyss) guarantee that +2 Aqua Tail in the rain OHKOs Blissey (it sucks that you would have to place it over either Surf, Hydro Pump or Baton Pass, though). I would generally recommend running it with Surf, Ice Beam, and Baton Pass (however, without Hydro, RestTalk Gyarados and Shuffle Cune have an easier time Roaring you out). Placing it over Baton Pass isn't really an option, as you are walled to hell by Vaporeon, and you would have no way of escaping.
