You're trying to do too many things with this set.
What's Acrobatics doing on here? Here's what Flying hits: Bug, Fighting, Grass. Bug types aren't very common in OU, except for Scizor, who wouldn't take that much anyway due to its Steel typing. Grass types are already covered by Ice Beam. Fighting types could be covered by Extrasensory, meaning you could remove those attack EVs and dump them into Special Attack and give it a Life Orb; it also gives you a move to hit Toxapex and Tentacruel if that's important. I don't even know if there's Fighting-types that are common in OU right now that don't get dunked on by your other coverage moves (Breloom dies to Ice Beam though Greninja wouldn't want to stay in on a Mach Punch, Terrakion dies to Water STAB). I suppose it does hit Mega Venusaur but I don't know how vital that is.
I'm not sure what Taunt is for. You'd usually run Taunt on like a suicide lead set so you can get up your layers without getting set up on yourself.
Please take this with a grain of salt as I've not really been too into SM OU, this is coming from a mostly ORAS perspective. A cursory look at OU usage rates for 7th gen doesn't seem to contradict anything I've said so far though.
