Golduck

Golduck stands out in ADV UU as a fast offensive Water-type that has access to Calm Mind. Its strong STAB Hydro Pump rips through even specially bulky foes like Kangaskhan and Ampharos. Golduck is also gifted with a unique ability in Cloud Nine, making it able to put a stop to weather-based hyper offense teams. Cloud Nine disables the Speed boost from Swift Swim and Chlorophyll, allowing Golduck to revenge kill Rain Dance Omastar and Gorebyss and Sunny Day Vileplume, as well as ignoring Sunny Day Arcanine attempting to weaken Hydro Pump by setting up sun. Golduck is a more aggressive alternative to another offensive Water-type in Slowking because of its good Speed, Cloud Nine, and no Rest turns to exploit, making it a better pick on hyper offensive teams that need a backup weather answer.

However, Golduck faces competition from the plethora of other offensive Water-types in the tier, such as Rain Dance Omastar, Swords Dance Tentacruel, Gorebyss, and Feraligatr. It lacks the defensive profile that enables Pokemon like Slowking to play the long game, which leaves it easily worn down by stray attacks and status as it tries to set up, and Golduck only makes up for it with its moderately fast base Speed stat. Additionally, Golduck's ability to revenge kill weather sweepers is replicated by Pokemon like Electrode and Ninjask, which can also revenge kill other fast Pokemon like Scyther and Tentacruel.
