Ludicolo

Ludicolo might initially seem like a terrible choice due to its poor movepool and subpar stats. However, Ludicolo gets Swift Swim, which doubles its Speed in rain, something easy to make use of as it is really common in Ubers due to the prevalence of Kyogre. Ludicolo might have a shallow movepool, but it attains great coverage from STAB Hydro Pump, Grass Knot, Ice Beam, and Focus Blast. Even Ferrothorn, the most popular Water-type resist in the tier, loses to Ludicolo as it is 2HKOed by Focus Blast. However, Ludicolo is no slouch defensively either. With its decent base 100 Special Defense and fantastic defensive typing, (which gives it weaknesses to Bug-, Flying-, and Poison-type attacks, all of which are rarely used in the Uber tier), Ludicolo can efficiently run a Leech Seed set. However, what really sets Ludicolo apart from its fellow Leech Seed users, such as Ferrothorn, is its access to Rain Dish, which heals Ludicolo's health by 6.25% per turn when it is raining. Ludicolo can potentially heal 25% of its health every turn factoring in Leech Seed, Leftovers, and Rain Dish. Ludicolo is also one of few Pokemon who can boast being able to check Choice Specs Kyogre. All in all, Ludicolo is probably the greatest example of the fact that appearances can be deceiving and every team ought to prepare for this pineapple or risk getting swept in its furious rampage.
