Nice team!! The two Toxic Stalling NFEs can really do a number on opponents.
Right now, it seems to me that Flame Body Chandelure can sweep your team, be it Choice variants with Trick or SubSplit Chandy. However, it doesn't have many opportunities to switch in, outside of Roserade or a predicted Darm U-Turn (since Flare Blitz will 2HKO it). You'll need to play carefully against it - you're probably gonna realize it's not Flash Fire when it doesn't switch into Darm.
SD Heracross can also attempt to sweep you, but I guess you can revenge it with Raikou or stall it for Toxic/Burn damage. Maybe you could try Aerial Ace on Gligar so it doesn't become set up fodder?
Those two are off the top of my head. I guess SubCM Raikou can also threaten to sweep you if it's given time to set up, but I guess you could say the same for your own Raikou.
Two things, is it worth running Superpower instead of Earthquake on Darmanitan? Is there anything specific that it hits harder? Keep in mind that it lowers your attack after the first hit. Also, U-Turn on LO Darm always seemed so wrong to me. The Pokemon is already SR weak, it doesn't need to lose an extra 10% for scouting the opponent's move... If you really want to use it, I'd advice you to try ScarfManitan, which allows you to revenge things like Scarf Heracross, Rotom-H and Weavile if you can't deal with them with your number one answer.
Also, small nitpick, but Roserade's moveset is illegal. Spikes and Sleep Powder are both egg moves and can't be used together — I don't know why PS! still has that issue.
Otherwise, cool team!
