A Stealth Rock set Metagross can use on Psychic teams in Gen 9 Monotype. The thing Metagross has that allows it to serve as an option over Jirachi for the Stealth Rock setter on Psychic teams is its access to priority Bullet Punch. Stealth Rock lets Metagross setup a hazard that chips opposing Pokemon switching in. Meteor Mash is used for the Steel STAB since it is Metagross' poweful physical Steel STAB and can potentially raise its attack stat to let it hit harder. Bullet Punch is a useful priority Steel STAB that allows Metagross to pick off weakened fast Pokemon. Metagross gets Knock Off now, meaning Metagross has a move to cripple switch ins such as Corviknight, Toxapex, Skarmory, and Archaludon. Knock Off is nice to make some sort of progress since most Pokemon don't like switching into a Knock Off. Earthquake can be used to hit Pokemon such as Toxapex, Steel-, and Fire-types such as Heatran, Gouging Fire, Volcanion, Kingambit, Iron Treads, Iron Crown, and Hisuian Goodra super effectively. Leftovers is used to give Metagross a little HP recovery.
