Kartana

Kartana is a monstrously strong as well as fast attacker that, thanks to Beast Boost, can become even scarier as it racks up Attack boosts with each KO inflicted. Even with its limited attacking toolkit, rarely running more than just Leaf Blade and Sacred Sword, it still manages to pressure metagame staples such as Tapu Fini and Snorlax. It can also provide speed control for its team with Tailwind or set up with moves like Swords Dance and Substitute, both of which put a great deal of pressure on the opposing Pokemon. Unfortunately, Kartana's paper-thin Special Defense will leave it easily OHKOed by even weak special attacks such as Porygon2's boosted Ice Beam or Mega Salamence's Hyper Voice. Additionally, Kartana also struggles with Fire-types like the commonplace Incineroar and Charizard, as well as Flying-types like Zapdos and Mega Salamence, which it cannot hit hard.
