Mid-stage Pokemon like Poliwhirl rarely see competitive play outside of special formats. It's a waypoint on the road to Poliwrath, which is where the real potential kicks in. An original Gen 1 pick. Sits at a decent but contested Speed tier.
Speed and HP carry most of Poliwhirl's stat budget. Sp. Atk's the obvious dump stat. Common in the wild and yields 2 Speed EVs. Follows a 1.06M XP medium-slow curve.
Its body surface is always wet and slick with an oily fluid. Because of this greasy covering, it can easily slip and slide out of the clutches of any enemy in battle.
Poliwhirl Weakness
GoodElectric and Grass-type moves hit Poliwhirl for super-effective damage. 4 resistances help offset the weaknesses. Water Absorb grants an additional Water immunity, reshaping the matchup chart.
- Dark and Steel types added — Fairy does not exist yet
- Moves are Physical or Special based on type, not per move
From here, Poliwhirl's line branches into Poliwrath and Politoed. That's 2 possible evolutions, each with its own method. So far, HP got the biggest boost (+25 from Poliwag). The final form adds another 125 stats on top.
How to Evolve
Breed with Poliwhirl to get Poliwag eggs easily using 58 partners from the Water1 egg group. Notable egg moves include Bubble Beam, Haze, Ice Ball and 4 more.

Without breeding, Poliwhirl misses out on Bubble Beam and Haze. That's 7 egg moves adding depth that the base kit lacks. STAB comes from Hydro Pump and Surf, with Normal and Ice coverage and more rounding things out.

Poliwhirl is meant to evolve into Poliwrath. At 385 BST, the stats aren't there for competitive play yet. Pre-evolution Pokemon rarely hold up against fully evolved threats.
Swift Swim is what you want on Poliwhirl. Every competitive set worth running is built with that ability in mind. The alternatives (Water Absorb, Damp) work on paper but Swift Swim is what makes Poliwhirl worth using.
Base 90 Speed is workable — faster than some, slower than many. On offense, Poliwhirl is leaning toward the physical side (base 65 Attack).
