I've been using offensive Vileplume for ages now, and far prefer it to the physically defensive defensive variant most people use. Before the drop of Slurpuff i ran Sleep Powder or Aromatherapy over HP Fire, but now Ferroseed is really starting to gain popularity to counter it, as are offensive Steel-types in Klinklang and Steelix. They are very quick to switch in on Vileplume, only to get completely obliterated by HP Fire (252/0 Ferroseed is OHKOd after one layer of Spikes or two Stealth Rock switch ins). This obviously makes Slurpuff a fantastic partner, but Klinklang also appreciates the removal of Ferroseed. This Vileplume is also a hard counter to its more defensive cousin, as Sludge Bomb far outdamages the opponents'. It also remains a useful counter to Gurdurr, special Sceptile, and many other Pokemon, but hits back far harder than the defensive variant. To Feraligatr looking to tank a Giga Drain from this Vileplume and set up a Swords Dance to kill with Ice Punch, they can guess again, as this Vileplume does a minimum of 98% to 252 HP Feraligatr, an easy kill. HP EVs give a LO number.
Some other cool stuff that are fun to use are Jolly 180 Speed Feraligatr (outspeeds max neutral Shiftry, and OHKOs with +2 Ice Punch, or Frustration after a round of LO recoil). Antilead Vivillon is also pretty cool, it's like the standard Quiver Dancer except with Sash and Stun Spore over a coverage move. Mostly people lead with their hazard setters, which Vivillon can easily put to sleep. Stun Spore again on the switch, and then just spam Hurricane (parafusion ehehehe). Grass-tyes immune to spore moves obviously aren't an issue due to Hurricane. U-Turn is used over Quiver Dance because you can easily gain momentum with Viv's disruptive moves (and if you want to be a goofball 20 Atk EVs kill Shiftry with U-Turn after Stealth Rock). This quickly sets the pace for an offensive team.
EDIT: have also been enjoying Jolly Band Torterra with Bullet Seed, Wood Hammer, EQ and Stone Edge. It's an awesome anti lead, as Bullet Seed snipes through Golem and Omastar (Oma has 55 Speed to Torterra's 56), while Wood Hammer breaks Rhydon.
