Initially thought I could run the standard Throat Spray set, but turns out Ogerpon hits STUPID HARD when Tera'd, at +2 we wouldn't even be guaranteed to get a clangsoul off. Sitrus allows us to get that little bit of healing we need to be able to use it, while still being able to ohko Ogerpon at +1 with Aura Sphere.
+2 252 Atk Cornerstone Mask Tera Rock Ogerpon-Cornerstone-Tera Ivy Cudgel vs. 0 HP / 0 Def Kommo-o: 204-240 (70.1 - 82.4%) -- guaranteed 2HKO
+1 252 SpA Kommo-o Aura Sphere vs. 0 HP / 4 SpD Tera Rock Ogerpon-Cornerstone-Tera: 338-398 (112.2 - 132.2%) -- guaranteed OHKO
Tera Steel is pmuch just to not get revenged by fairies
