Basic Vileplume

Leftovers
Moveset
~ Sleep Powder
~ Leech Seed
~ Sludge Bomb
~ Moonlight

Leech Seed whatever comes in, and if you think it isn't a Sleep Talker, sleep it. Moonlight for recovery, and Sludge Bomb as an attack.

Other Options

Stun Spore can paralyze stuff, which is good because Vileplume is slow. Swords Dance could make Sludge Bomb hurt, but Victreebel does this better since it's faster. Razor Leaf could be used as an attack (watch out, as Razor Leaf is illegal with Leech Seed), and Reflect could boost Defense while you Leech Seed.

Opinion

Vileplume is a cool Pokémon. It's got decent stats all around, even though Venusaur beats it in stats in just about every way. Luckily for Vileplume, its movepool outclasses Venusaur's with Sludge Bomb and Stun Spore. Vileplume is more of a status inducer than an all-out attacker, and it does well in UU.

Counters

Fire-types like Arcanine, Flareon, and Magcargo tend to do well by hitting one of Vileplume's weaknesses. If Vileplume's only offensive move is Sludge Bomb, many opponents wall it, such as Sudowoodo and Omastar with Ice Beam; they take a bit of nerve to switch in, though, as they are weak to Grass. A less risky choice along the same lines is Gligar. Shuckle and Magneton can scout for Vileplume's moveset, but unfortunately can't do any real damage to it. Qwilfish can Curse up against it.
