one day we'll have an OU discussion thread that is actually about the current metagame and not aggressive mudslinging about potential tiering and doom posting.
Embrace the should-be-a-shitmon life and embrace Maushold.
Maushold is a family, a loving family. Maushold is love. Maushold is (family) life.
Ogerpon-Wellspring giving you problems? Population Bomb kills from full with eight hits, so you have a reliable revenge killer.
Last-mon Kingambit destroying your team with Sucker Punch? Maushold says hello, my name is Encore, prepare to die.
Deathly vulnerable to Sticky Web leads? A Maushold lead beats both setters, and Maushold is uncommon enough that they probably don't have a specific contingency plan, so you're likely to chunk something hard.
Really loath Gholdengo? Tidy Up isn't blocked by Good as Gold, and Tera Dark sets win if Gholdengo switches in to try and set up, since +1 Tera Dark Bite OHKOs offensive Ghold and can trade itself for the defensive set.
Kyurem? You can revenge anything except the DD set, and can 1v1 SubTect (though only once if you get predicted and switch into an attack).
It still has all the problems of needing help getting in safely, but playing it as an offensive mon, rather than an exotic hazard clear option, is fun. Population Bomb is just a gross move, and the fast Encore is great utility.
