Naganadel

Naganadel's high base Speed and strong typing make it one of the best Tailwind setters in the tier, allowing it to get the first Tailwind off frequently, and letting it match up favorably against common Pokemon such as Rillaboom, Tapu Fini, and Urshifu-R. Naganadel's Tailwind utility is appreciated on many structures, but shines brightest on offensive archetypes where teammates such as Heatran, Zygarde, and Urshifu-R can get an immediate Speed boost and start firing off strong attacks. Naganadel appreciates all three of these Pokemon's ability to deal with Heatran and other Steel-types, while in return Naganadel deals with Tapu Fini as well as Rillaboom for the latter two. However, Naganadel is completely useless into Heatran, and its frailty leaves it susceptible to being KOed early, therefore limiting its potential to set up multiple Tailwinds. It also struggles into opposing forms of speed control, especially Trick Room, and usually can't fit Protect in its repertoire due to it wanting all 3 of its attacks and Tailwind. Its inability to fit Protect and bad matchup against opposing speed control expose its poor bulk even more, while also meaning it cannot block the everpresent Fake Out and instead must rely only on its partner keeping it safe. Lastly, Naganadel is heavily prediction reliant as failing to get KOs puts it in danger.
