Yeah, I wouldn't mention poliwrath, either. Honestly, there are just so many better swift swimmers, like kingdra, kabutops, omastar, and heck even ludicolo. Base 85 attack is not going to be enough in ubers, either (kingdra has 85, too, and ludicolo has 90 but both have a 120 bp STAB instead of 80), so it will have problems with a ton of common opponents, like groudon and the giratinas and lati@s and palkia. Low attack+ weak STABs really makes it unviable imo, especially with so much direct competition. Fighting STAB is sorta useful but kabutops can use low kick for the same coverage while being much stronger, having rapid spin, and checking EK arceus better with its rock typing. Other notable targets are dialga and ferrothorn, but again, kabutops can low kick them, omastar doesnt even need coverage for them lol it can just shell smash then kill anyway (plus dialga eats an earth power to the face), and ludicolo gets focus blast, however shaky. this probably seems like a pointless rant, but I hope my main point is still clear enough.
