Additonal move options: Leech Seed, Roar, Rock Tomb
Additional item options: Occa Berry, Yache Berry
Notes: Max HP and Defense with an Impish nature is needed to minimize the chance for Band Stoutland to 2hko after Stealth Rock to near nonexistent.
248 Spe EVs outspeeds Jolly Golem and Adamant Ursaring.
16 Atk EVs and an Adamant nature is optimal for OHKOing Jolly Golem through Bullet Seed (3 hits or more).
252 Spe EVs and a Jolly nature outspeeds up to and including Scarf Chatot after a Rock Polish.
A spread with enough defense on an Occa Berry set survives +2 Life Orb Adamant Flare Blitz from Monferno after Stealth Rock.
Occa Berry survives +2 Fire Blast from Ninetales with max or near max HP EVs after Stealth Rock.
A spread with the right amount of SpD and Atk EVs on a Yache Berry set can trade KOs with +2 Orb Simipour and almost always Rotom-Frost after Stealth Rock.
