It's likely not the best team, but I'll give you what I use, and have had some nice success with:
Multiscale Dragonite w/Lum Berry 252 HP / 144 Atk / 108 Spd - Adamant Outrage Fire Punch Dragon Dance Roost
Scizor w/Scizorite 252 HP / 252 Atk / 4 Spd - Adamant Bullet Punch Thief Swords Dance Roost
Azumarill w/Leftovers 252 HP / 252 Atk / 4 Spd - Adamant Aqua Jet Play Rough Superpower Belly Drum
I know what you're thinking: All physical attackers? Suicidal.
Well, they're all pretty bulky, and they have great type coverage between them, and they all have a boost move they can use when the situation arises. I lead with Dragonite, and the simple fact that it holds a Lum Berry seems to stop the NPCs using status moves whatsoever. (Tried Leftovers before and literally everything I started up against had Thunder Wave.)
I just go for a mix between power and attrition. Heal up when I need to, boost when I can, and sweep 'em out.
