First off i don't get why you run defog+spikes skarm, isn't that counter productive? lol. conk is also your only answer to thundurus, so you might wanna remember that, this team lacks bird spam check so you are naturally very weak to talonflame and even opposing mega pinsir because for some weird reason you have not fully invested your pinsirs speed. mega slowbro/ manaphy even proper stall in general can easily take this team out, lastly your team falls to mega swampert+kindra or rain teams in general. mega diancie is becoming kind of popular and that can potentially remove like four of your mons clean out but since u have azu as a revenge killer i woudnt really bother myself with much of that.
I think sand can benefit this team p well, ttar>chomp and exca>drgonite is a p good option. ttar also acts as a check to talon lol. while in sand exca can remove so many of your threats like mega zard x, mega diancie, mega pinsir. this team still cant deal very well with rain teams, and pinsir seems to be your main sweeper, and azumarill and conk take on important threats to the team, so its up to you what you want to change what you dont want to lose to. your still weak to rain teams, so i would look into that lol.
so i have put the changes in the spoiler
also if you want you could look into scarf ttar to
check all types of birdspam but that's up to you.
you might wanna think about your team from scratch again but hope i helped n_n
EDIT: For future reference if you are going to change your team around please update the op, otherwise its kinda ass to figure out what u have and what u dont.
