Couldn't find a recent discussion on Rampardos, so here we are.
#409 Rampardos
Base Stats: 97 HP / 165 Atk / 60 Def / 65 SAtk / 50 SDef / 58 Spd
Ability: Mold Breaker (opponent's attack-negating abilities are negated)

Rock Polish
The big big boost for Rampardos came in the news of Sandstorm granting a 1.5x increase in rock type's special defense, which turns that abysmal base SDef up to a much more manageable level. Rampardos hits damn hard with 165 base attack but unfortunately lacks much in the way of defenses and speed, although its base HP is quite impressive. Really Rampardos is a force to be reckoned with, but he needs to be played carefully. The Glass Cannon metaphor works well here.
It's ability, Mold Breaker, allows it to hit anything in the game that has an ability that would otherwise negate Rampardos' attacks. I only wish he got more attacks that made use of this, rather than just being able to Earthquake things like Gengar and Weezing (although that is quite good). Elemental fangs would have been nice, but I suppose you can't have everything.
Rampardos @ Choice Scarf
Nature: Adamant (+Atk -SAtk)
Trait: Mold Breaker
EVs: 112 HP / 188 Atk / 112 Spd / 96 SDef
-Earthquake
-Stone Edge
-Pursuit
-Hammer Arm
This is meant to take the lead. It survives an Adherence Scarf Gengar's Energy Ball guaranteed while it can OHKO with Earthquake. Pursuit, unfortunately, is not a OHKO unless Gengar attempts to switch out.
Rampardos @ Choice Band
Nature: Jolly (+Spd -SAtk)
Trait: Mold Breaker
EVs: 52 HP / 252 Atk / 204 Spd
-Stone Edge
-Earthquake
-Pursuit
-Hammer Arm
Use with a Tail Winder. Tail Wind, then switch to Rampardos and it outspeeds Jolly Garchomp, allowing you to hit hard with one of Rampardos' attacks. It also outspeeds Gyarados without any Dragon Dances and AG Salamence should they switch in on the same turn Rampardos comes in on Tail Wind. Stone Edge is an easy OHKO against both of them.
Rampardos @ Leftovers
Nature: Adamant (+Atk -SAtk)
Trait: Mold Breaker
EVs: 4 HP / 252 Atk / 252 Spd
-Stone Edge
-Earthquake
-Pursuit / Crunch
-Rock Polish
Outspeeds some Choice Scarf users after Rock Polish and hits hard with its attacks. Not very durable at all, but 471 attack isn't something that most Pokemon can just shrug off.
