I don't have much competitive experience, the only thing I've done with this team was go to a local 2v2 tournament which I pwned 'em all badly. Not even sure their pokemon was trained correctly, I saw some Great and Ultra balls.. So that doesn't mean a win.

Anyway, any suggestions for this team?

Unfortunately, Roserade has long since been moved up to the OU tier, so this team is no longer considered standard. That means pokemon like Ninetales, Sudowoodo, and Gardevoir just won't be able to pull their weight against top-tier OU threats. Or you could replace Roserade with a UU lead I suppose, it's up to you ;D

Darn people using Roserade.
Any idea for a good UU lead?
Until I make a team built of Pokemon I like (It was also specifically for UU) someone has to come up and ruin it.
