Victreebel

Victreebel's main niche in NU is being one of the best sun sweepers in the tier. With fantastic wallbreaking capabilities thanks to its very high Special Attack stat and great overall coverage with STAB moves in Solar Beam and Sludge Bomb, it's a staple on almost every sun team. It also has access to Weather Ball, a very strong Fire-type move in the sun that hits Pokemon that its STAB moves can't. What separates Victreebel from other sun sweepers like Exeggutor is that it can outspeed a large portion of Choice Scarf Pokemon under the sun without running a Timid nature, thus allowing it to have more power. However, Victreebel cannot function outside of sun due to its lackluster Speed and defenses, which leave it susceptible to common priority moves such as Bullet Punch, Fake Out, Ice Shard, and Sucker Punch.
