Level 100 Statistics (see level 5, 50, 100)
Oddish is arguably the best Chlorophyll sweeper in LC due to its higher Special Attack and bulk compared to other Chlorophyll sweepers. It is, however, one of the slowest Chlorophyll users. Oddish's high Special Attack stat and powerful STAB Grass and Poison attacks are what makes it a top tier sun sweeper. Its immunity to Toxic is also very useful because many common defensive Pokemon in Little Cup do not like being poisoned. Because of this, Oddish and other Poison-type Pokemon have a nice niche in the metagame.
Chlorophyll doubles Oddish's Speed, giving it a Speed stat of 26, which outspeeds all but a handful of Choice Scarf users, namely Mienfoo and Chinchou. 0 HP IVs give Oddish 19 HP, which means Oddish only takes 1 damage from Life Orb recoil. SolarBeam hits in one turn because of the sun, and thanks to STAB, it has a massive power of 180. This will hit any Pokemon that doesn't resist it extremely hard, except for a select few special sponges such as Lickitung and Munchlax. Hidden Power Fire is Oddish's secondary attack, and gets a 1.5x boost from the sun, giving it a power of 105. This is Oddish's only attack that hits Steel-type Pokemon super effectively, as they resist SolarBeam and are immune to Sludge Bomb. It is also useful against Grass-type Pokemon, as many of them have Poison as their secondary type, namely Bulbasaur, Bellsprout, Oddish, and Budew. Sludge Bomb is Oddish's second most powerful attack other than SolarBeam. Coverage-wise, it hits Fire- and Dragon-types, and it can be used outside of sun. Sleep Powder is a great alternative to Sludge Bomb, allowing Oddish to put a member of the opponent's team to sleep and then take free shots at them. Sleep Powder's prime use is to put the opponents sun counters to sleep, should they carry any.
Team Options & Additional Comments >>>
Oddish has a shallow movepool, and has but a few other options. Oddish could run a Sword Dance set, though its Attack is rather low and its physical movepool is quite shallow, consisting of only Seed Bomb and Double-Edge. A SubSeed set is somewhat viable with sun support, but Oddish is outclassed as a SubSeeder by Cottonee, who has Prankster and does not require sun support.
Checks and Counters
Snover is the number one counter to any sun sweeper. Snover can come in as you use SolarBeam, induce hail, and make you charge the move up. Oddish is then trapped, and Snover can OHKO it with 100% accuracy Blizzard thanks to hail. However, if you can predict a Snover switch-in, Oddish can OHKO Snover with Hidden Power Fire. Hippopotas can change the weather thanks to Sand Stream and halve Oddish's Speed. Oddish can put it to sleep with Sleep Powder, though. Lickitung and Munchlax sponge Oddish's powerful special attacks with their high Special Defense stats. Both can set up Curses against Oddish, and Munchlax can threaten to OHKO it with Fire Punch.
