I got a Octazooka Sableye.
I got a Hydro Pump Magikarp.
Anyone got any ideas?
Hydro pump Gyarados has a microscopic niche in Generation 3 OU, where it can 2HKO Claydol while surviving explosion and losing only about 1/4 of its HP from psychic. In all earlier generations, hydro pump Gyarados is outclassed by Cloyster. In all later generations, it's outclassed by waterfall Gyarados.
Octazooka Sableye is outclassed by water pulse Sableye.
