>>20488879It's S-ranked in UU (i.e. really one of the best mons of the tier), because the high base power of its moves makes up for the lower offensive stats, while being much bulkier than most offensive mons and having better speed than many. It can run a wide array of sets between band, specs, scarf, TR, Ebelt with optional special coverage moves. Right now it's mostly used as a wallbreaker with band. It's even viable in OU.
>>20488564I'm not a fan of Fake out on Mienshao, since it has rather low damage output against anything that isn't horribly frail like Galvantula (but you wouldn't stay in on Galv anyway since it has a good chance of KOing with Thunder after one tound of LO recoil). Stone edge is an option, although it admittedly isn't nearly as important as it was last gen because Knock off gives nice coverage already. SE hits Crobat, Aerodactyl, fairies and Heracross harder. I guess Fake out is nice for some damage on scarfers trying to revenge kill that can't heal, and it can sometimes stop a last-mon sweep by sacking your team and fake outing over and over.
Normally you also shouldn't switch Tini into Chesnaught, since it leech seeds everything and then shields to deal some damage and scout what your most likely choiced Tini will lock itself into. It's hard to say much more from the replay because most of your team (assuming you are the guy that won) wasn't used and your opponent had some really funky movesets like Aerodactyl that can't hit steel types and Electro ball Galv.
