[Other Options]

<p>Don't use any of Politoed's other abilities, as if you do, you may as well use a better Water-type like Jellicent or Vaporeon. Politoed’s only other notable support option is Haze. Politoed can also use the RestTalk strategy to keep itself healthy, and this can be particularly annoying combined with Scald's burn chance. Politoed can also forgo Sleep Talk on such a set and pack a Chesto Berry for a one-time no-penalty full recovery.</p>

<p>Offensively, Politoed does have access to Belly Drum, but lacks the Attack and Speed to utilize a set based around it. Also, quite frankly, you don't want to sacrifice 50% of your weather starter's HP for a sweep that will almost assuredly fail. Politoed can also use Endeavor for a surprise, but in most cases one of its coverage options is the better choice. Politoed can run an all-out offensive set with a non-choice item, such as Life Orb or Leftovers, but this is generally better left to Politoed's offensive rain teammates. Lastly, Psychic can be used on any set for screwing with Toxicroak, which otherwise walls Politoed entirely.
