Great suggestions! There's so many different options @ -@
Now that I'm looking at them again, I think Mr. Mime is my ideal passer
eek I can't believe I'd never thought of him before. Calm Mind, Barrier, Nasty Plot, Charge Beam- he has everything I want * ~* Obviously not all four of those in one set, lol. I'm thinking I'd go with something more like this-

@Leftovers, Soundproof, Calm
252 HP / 40 SpD / 216 Spe
Calm Mind
Barrier
Baton Pass
Psychic
Alternately, he could Trick a Choice item instead of Psychic to give him more freedom to set up.
I can't quite decide on a bulk right now- you guys have some great suggestions. I guess I'll figure it out when I have a bit more of my team finalized. Right now I really like Dusknoir and Umbreon, but we'll see what happens o 3o
For a lead, I think I might go with this lovely mixed anti-lead Infernape-

@Focus Sash, Blaze, Hasty
129 Atk/129 SpAtk/252 Spe
Fake Out
Overheat
Close Combat
U-Turn
From experience, this guy is AWESOME. My boyfriend came up with this set for use in the Battle Frontier and it's served both of us very well. I admit that the Battle Frontier is quite different from real competitive play... but I dunno. I really have faith in this little guy to completely wreck your s**t.
biggrin Well, your leads. That and I just freaking love Infernape. He's pretty simple to use- Fake Out the opponent first thing, use whichever offensive move seems more effective, U-Turn out of there when the lowered stats make things too dangerous. The fun part is that he's basically guaranteed at least three turns in battle, no matter what he's up against.
