Sandslash @ Life Orb / Leftovers
Trait: Sand Rush
EVs: 252 Atk / 252 Spd
- Swords Dance
- Stone Edge
- Rapid Spin
This is one of the best revenge killers to use with Sandslash's new ability: Sand Rush. Despite his pathetic speed of 65, in sand he outspeeds everything in OU slower than base 108 scarfers and Scarfed Latios. In addition to speed equal to Deoxys-S, he also has a usable attack stat of 100, STAB Earthquake, and Rapid Spin. No longer does offensive rapid spinning fall onto only Starmie; Sandslash is way faster and can set up Swords Dance. He also has incredible natural physical bulk, at 75/110. This means he can take a blow or two without any investment and he won't die. Starmie has nothing near that kind of bulk, and thus leftovers is far more viable on Sandslash.
The drawbacks are that he isn't THAT strong in the end, and while hes almost as fast as Choice Scarf Terrakion, he isn't quite as powerful. The pros are that he can switch up moves, and importantly he is one of two offensive rapid spinners that are usable in OU. That alone gives him a massive niche for sandstorm teams that want more offense but also a way to deal with entry hazards.
