Weavile

With its low-risk, high-reward Knock Off backed up by Triple Axel and an excellent Speed tier— which allows it to outspeed the entire unboosted metagame barring Dragapult, Tapu Koko, and Zeraora and fire off strong attacks without taking a hit itself—Weavile establishes itself as a top threat every team needs to be prepared for. Knock Off and Triple Axel have amazing synergy, as Triple Axel's main flaw is that Rocky Helmet users that can take a Triple Axel can punish Weavile with heavy damage, but Knock Off can remove Rocky Helmet from these Pokemon, allowing Weavile to use Triple Axel more freely. Its Dark / Ice STAB combination also allows it to threaten many tier staples such as Landorus-T, Tornadus-T, Galarian Slowking, and Slowbro with an OHKO, forcing out these Pokemon to gain opportunities to spam Knock Off. Weavile also serves as a valuable check to Swords Dance Garchomp and Choice Specs Dragapult, with its Ice Shard OHKOing Garchomp after its Defense is dropped by Scale Shot, as well as serving as one of the tier's only Ghost-resistant Pokemon. However, Weavile is held back by various contact-punishing effects, including the previously mentioned Rocky Helmet as well as Flame Body, Static, and Iron Barbs. Flame Body Heatran and Volcarona can take Triple Axel with ease while being favored to inflict a burn on Weavile, ruining its offensive capabilities. Zapdos cannot safely switch into Weavile, but it has favorable odds to inflict paralysis when Triple Axel is used, and a paralyzed Weavile is nearly useless in many matchups due to its poor bulk and defensive typing.
