SLUSH RUSH ABUSER
Sandslash @ Life Orb/Chople Berry
Ability: Slush Rush
EVs: 252 Atk / 4 SpD / 252 Spe
- Swords Dance
- Icicle Crash
- Iron Head
Both Icicle Crash and Iron Head are the main offensive moves. Both of them get STAB and 30% flinch rate. Earthquake completes the coverage allowing it to face opposing Steel and Rock types and punishing possible Fire opposition. Thanks to some key resistances as Psychic or Fairy and to its 120 base defense, it can set Swords Dance to raise its attack. For nature, go to Adamant if you want full power, or Jolly if you want to outspeed opposing non-scarf Pheromosa or scarf Genesect. Life Orb is the main item to use, but you can use Chople Berry to survive a Fighting move and set up or attack.
Alola Sandslash main partner is Alola Ninetales which set up hail, Aurora Veil and can scare Fighting types with Moonblast. That Hail+Aurora Veil support allows Sandslash to do its job to the fullest (Vanilluxe can also fit for that role, but in a lesser way).
Another great partner could be Dugtrio, thanks to its power to trap and eliminate Steel, Rock, and Fire types, making easier the work of Sandslash (have in mind Alolan Marowak can't be trapped). Magnezone could be also considered for trapping Skarmory and Celesteela.
