What Is the Build of Michael Kelsch’s Ogerpon Cornerstone?

Ogerpon Cornerstone has a deceptively good typing in Grass/Rock, as the two types synergize well enough to remove most of their individual weaknesses. So, the only types that would hit Ogerpon Cornerstone for super-effective damage were Bug and Steel, both relatively rare types. Michael didn’t have much choice with the Item and Ability as Ogerpon has to hold the Cornerstone Mask and has the ability Sturdy as a result. Still, Sturdy provided an in-built Focus Sash, letting Ogerpon survive one hit from full HP.
