eelektross works really well, same with a mixed sheer force druddigon/nidoking. assault vest regenerator tangrowth is like a god of mixed sweeping because of it's great offenses, exceptional bulk, and reliable recovery. mega abomasnow is a monstrosity if used correctly, same with mega latios cause of the +40 attack buff and access to DDance. victini hits very, very hard with a mixed set, since it has access to powerful stab moves that break any wall. infernape is your classic example of a mixed sweeper, whereas a mega-zard X can instill some real fear into your opponents who expect the flare blitz and send out their physical walls to counter. kyurem-black and deoxys speed are heavy hitters that can throw your opponents for loops for days and days.
however, I stand by the idea that the best mixed sweeper is still meloetta, who can literally change it's typing and offensive utility based on a stab move that has a 20-something% chance of putting the opponent to sleep. she was literally built on the premise of mixed sweeping, and when you see a blissey charge in on you and you relic song+close combat/drain punch it in it's life then you'll really feel like you're doing the job well.
