Lucario

With good offensive stats, access to Nasty Plot and Swords Dance, and a wide movepool, Lucario is a menacing and unpredictable setup sweeper for offensive teams. It also has a good defensive typing with nifty resistances, allowing it to check Pokemon like Scizor as well as having an immunity to Poison, aiding in its ability to set up. However, this is offset by Lucario's meager defensive stats, meaning that it has to rely on forced switches and its resistances for setup opportunities. It also has a middling Speed stat that, while circumvented somewhat by its access to priority moves, leaves it vulnerable to faster threats that can take a hit, like Mega Aerodactyl and Krookodile. Lastly, Lucario faces heavy competition from the tier's plethora of other Fighting-types and struggles to stand out from the likes of Terrakion and Infernape.
