Bouffalant

With an excellent base Attack stat of 110, access to Reckless, and an exclusive recoil move in Head Charge, Bouffalant can hit extremely hard. Bouffalant can also use Swords Dance to boost its Attack stat to sky-high levels, letting it hit even harder. It takes care of the most common physical walls in the tier, at worst 2HKOing them, and can outspeed and Taunt them, preventing them from doing much back. While Reckless makes Bouffalant the powerhouse that it is, it also has access to Sap Sipper, giving it immunity Grass-type moves, including Leech Seed and, crucially, to the most common sleep-inducing move, Sleep Powder. With this, Bouffalant also receives a welcome boost to its Attack stat.

In addition to these assets, Bouffalant has great bulk too, with base 95 in all three defensive stats; therefore it takes little damage from weak attacks, and with screen support, takes minimal damage even from the strongest moves. Despite these strengths, Bouffalant is weak to the common Fighting-type moves and is pretty slow, often ending up a sitting duck while setting up. Even with these minor flaws, Bouffalant is still a great wallbreaker and can sweep late-game.
