It is. Sand Rush + 88 Speed lets it rape through most Pokemon with QuakeSlide coverage (and yes, I'm aware a neutral Rock Slide does as much as a resisted Earthquake).
Victini was revealed to keep its Japanese name recently.
What's cool is that Magcargo gets this after evolving from Slugma:
-Shell Smash
-Lava Plume/Fire Blast
-Earth Power/Earthquake
-Stone Edge
Nature: Naive
EVs: 4 Atk/252 SAtk/252 Spe
Item: White Herb/Life Orb/Leftovers
Ability: Flame Body
Still, Magcargo is better off with defending. What would happen if Torterra and Blastoise got this?
Agreed. What do you think about Shell Smash? I'm glad they made it because it's a combination of Swords Dance, Nasty Plot and Agility, but with Close Combat's side effect.
