Poliwrath, I feel is a viable candidate to be considered useful in this metagame, as the set-up options are there for it thanks to all the bulky Water-types running around in this tier, barring Slowbro and Slowking. Poliwrath is the safest Scald switch-in available to UU, which then gives it the ability to set its Substitute up, and abuse hazards via Circle Throw. Many of the bulkier Pokemon in the tier, such as Gligar, Bronzong, and Rhyperior, are also functional set-up bait for Poliwrath, given that two of the three listed are afraid of Poliwrath's Water-type STAB, and Bronzong simply cannot do anything to Poliwrath to either break its Substitute or avoid taking damage. Sharpedo, considered to be one of the best late-game cleaners in the tier, is brought to a screeching halt by Poliwrath, as Earthquake is only doing enough to 4HKO (when Poliwrath runs 252 HP / 252 Def). Did I mention that Poliwrath is also a very effective check to Weavile? Poliwrath's main checks fall into four categories, Electric-types, Grass-types, Psychic-types, and Flying-types. Pairing it with a Rhyperior for example, gets rid of two of those weaknesses, gives Rhyperior something to sponge Water-type attacks with, and hazards for Poliwrath to abuse. Victini, provided is still UU after these next upcoming weeks, is also able to handle the Grass- and Psychic-type attacks thrown at Poliwrath. Victini and Poliwrath also synergize well together, as Poliwrath once again absorbs the Water-type attacks aimed at Victini, while in return Victini handles the aforementioned Grass- and Psychic-type attacks. Even Pokemon like Crobat, who are theoretically weak to a solid third of the tier, still find ways to be successful by sticking to their niche and through team support. This case is no different than Poliwrath, as it is used to check, and sometimes counter, opposing Water-types. Once behind a Substitute however, one can be more liberal with how they use Poliwrath, as it then becomes a very effective phaser. I'm not saying that everyone should jump on board with this right of the get-go, but rather that Poliwrath is another one of the options available to our welcoming tier. If I had to rank it on the Viability thread, it would be looking at something like C-Rank, as it's great at performing the job it needs to, and it's a Fighting-type. If you want to use a sweeper, use something like Heracross or Mienshao. Poliwrath is a bulky Pokemon meant to go toe-to-toe with opposing Water-types, sans Slowbro and Slowking, Substitute up, and start roughing them up. It works well on bulky offense teams and even stall teams that need something to handle either opposing Water-types or a reliable phaser.
