Kinda threw it together fast, but I like it. Go ahead and rip it apart, I don't mind. Just make sure it's constructive. This team relies on strategy, not power, but...yeah. I'd rather not replace any of 'em, but I don't care that much. Well, go ahead...I know it isn't great. Well, blast away.

My Electivire can run over this team :P

Why didnt you give Steelix Gyro Ball? :(

Oopsies, forgot to mention it's 3rd gen. Stupid me.

 

[Samson]

there is no BL in 3rd gen btw.

Looks good, but I would make Vileplume hold Black Sludge, and Steelix hold Iron Ball, then replace Rock Slide with Gyro Ball, and you can still EQ fliers.

EDIT: 3rd Gen? Forget what I said.
