Out of all the Ogerpon forms, Rockpon always felt the most underated despite having some insane tools at its disposal. The one thing I've always wanted was a reliable Rock-type move that doesn't miss all the time, and they not only gave us 100% accuracy STAB Stone Edge with more PP, but there's even the potential to gain 120 BP with Tera boost. Which is absolutely bonkers. This thing can theoretically just smack things around using one of the best offensive typings in the whole game without having to worry about resistances, or even things like Spore and Rage Powder.
So today's main focus is to turn Ogerpon-Cornerstone into a bundle of stats with Sand boosting it's Sp Def, Trailblaze for Speed, and Terastilized Embody Aspect for Def once it no longer benefits from Sturdy or Grass-typing. SD can be used to boost its Attack, but this set opts for Focus Energy instead to capitalize on those crits and ignore Intim spam, which it's normally quite weak to.
We also have a Slow Tornadus to win weather wars, AV Ttar being unbreakable with surprise Tera Blast Fairy, and Rock-type Weather Ball Lando being able to punish Flying mons that try to wall the usual Sandsear set. (And you might be thinking, "Why's this idiot bringing a focus sash pao onto a sand team?" But it really only has to do 1 of 2 things; Sword of Ruin to help Oger kill more, or just being an overall offensive threat/support during the times when sand isn't available).
Basically, every other member is an ingredient designed to help turn this week's feature mon, Rockpon, into the true Cornerstone of the team by making it an unstoppable, wallbreaking monster.
