Naganadel

Outside of its relatively high Speed, decent coverage, and nifty access to Tailwind for a fast attacker, Naganadel leaves a lot to be desired, relegating it to being a mere niche pick for hyper offense teams. With its noteworthy Special Attack, base 121 Speed that allows it to get the jump on numerous key threats, and Dragon / Poison / Fire coverage that lends it the ability to hit virtually everything in the metagame, Naganadel can be an easy way of applying pressure to numerous high-profile Pokemon in DOU such as Mega Metagross, Tapu Fini, Zygarde, Kyurem-B, and Tapu Bulu. Naganadel relies on its Speed to do its job quite heavily, and it even has an ability in Beast Boost that supplements that, as it gets a Speed boost for every KO; this reliance, however, is also easily punishable, as its frailty can leave it helpless when facing opposing speed control in Tailwind or Trick Room, though Beast Boost can help against the former somewhat. Naganadel's frailty also means it has no defensive value whatsoever, being unable to safely switch in most of the time, and at times, it has an overreliance on its coverage to get KOs. Often, unless on a team bent on applying overwhelming pressure, Naganadel is simply overshadowed by other threats such as Tapu Koko that provide more utility and flexibility to their teams.
