What separates Golduck from the pack is Swift Swim — it doubles its Speed in rain. Combine that with Water typing and it sits at a decent but contested Speed tier. Can go either physical or special depending on the set.
An unusually even spread gives Golduck flexibility. Sp. Atk barely edges ahead. But Defense isn't far off. Moderately hard to find and follows a medium-fast 1M XP curve. Yields 2 Sp. Atk EVs.
Its body is strong, and it has webbing on its hands and feet. Golduck can swim easily through rough seas, clawing its way through the high waves.
Golduck Weakness
GoodGolduck's Water typing leaves it vulnerable to Electric and Grass moves. 4 resistances help offset the weaknesses. With 80 HP and balanced defenses, Golduck can afford to eat a neutral hit or two.
Evolved from Psyduck. Golduck is the final form in this two-stage line. Plenty of partners for breeding via two egg groups. Eggs are average hatch time. HP grew the most through evolution (+30 over Psyduck), and Golduck peaks at 500 total stats.
How to Evolve
One guaranteed turn is all Golduck needs. Focus Sash buys it, max Sp. Atk and Speed EVs make it count, and Swiftswim adds something extra. The goal: deal early damage and deal damage with Surf. The remaining moves gives it play beyond just the lead turn.

Swift Swim changes the entire equation for Golduck. The 500 BST doesn't tell the full story. Ranked C-Tier.
Psyduck evolves into Golduck at level 33. Golduck is the fully evolved form. At 500 BST, it's got solid stats to work with.
Swift Swim is what you want on Golduck. Every competitive set worth running is built with that ability in mind. The alternatives (Damp, Cloud Nine) work on paper but Swift Swim is what makes Golduck worth using.
Base 85 Speed is workable — faster than some, slower than many. On offense, Golduck is a special attacker with base 95 Sp. Atk. Defensively? Enough bulk to take a hit or two.
