This isn't a full team, but it's one of my evil set ups that make people shit their pants.
Machamp (M) @ Lum Berry
Trait: No Guard
EVs: 252 Atk / 148 Def / 108 SDef
Adamant Nature (+Atk, -SAtk)
- Ice Punch
- Stone Edge
- DynamicPunch
- Mimic
Lapras (F) @ Leftovers
Trait: Hydration / Water Absorb
EVs: 252 HP / 100 Def / 156 SDef
Impish Nature (+Def, -SAtk)
- Curse
- Ice Shard
- Rest
- Sheer Cold
Yup. If you haven't seen it by now, then you need to get your eyes checked. This is a Mimic+ Sheer Cold combo. The catch here is that Machamp has No Guard. Meaning that once he gets it, he can utterly wreck the other team. Yeah it's a two-turn set up, and it's kinda risky. I've used this quite a bit, and it's only failed me once. Lapras' bulk ensures that it'll survive the hits, because more often than not they are going to target her.
