Hawlucha

Hawlucha is one of the tier's deadliest sweepers thanks to its solid offensive STAB combination, high Speed, Swords Dance, and an incredible ability in Unburden. With the combination of a terrain seed and the Unburden ability, Hawlucha outspeeds many faster foes, ranging from Mega Alakazam, +2 Shift Gear Magearna, and Mega Swampert under the rain to Choice Scarf users like Kartana and Greninja. Hawlucha often finds setup opportunities against common Pokemon that it forces out, such as Ferrothorn, Heatran, defensive and Choice Scarf variants of Landorus-T, and Choice Scarf Kartana. Hawlucha also has the benefit of being a setup sweeper that isn't revenge killed by Ditto, as Ditto cannot copy the Speed boost from Unburden. However, Hawlucha is burdened with a below-average Attack stat, as it cannot OHKO targets like Tapu Lele, Mega Latias, and Tornadus-T before a Swords Dance boost, and it is unable to OHKO defensive staples like Slowbro, Toxapex, Tapu Fini, and Clefable after a boost. Hawlucha also struggles against Electric-types that resist both of its STAB options, like Zapdos and Tapu Koko. While Unburden is one of Hawlucha's greatest strengths, it is also one of its greatest weaknesses; once Hawlucha activates Unburden, it only has one shot at a sweep, and it is highly susceptible to being phazed by moves like Whirlwind from Skarmory. Lastly, Hawlucha is prone to being picked off by priority moves like Ice Shard from Weavile, Water Shuriken from Ash-Greninja, Quick Attack from Mega Pinsir, and Fake Out + Quick Attack from Mega Lopunny, especially if Hawlucha does not carry Roost.
