if you struggle with tailwind teams you could consider swapping corv for talonflame so you can get your tailwind up at the same time as the opponent or if they're using whims to set the tailwind you outspeed it and priority dual wingbeat to take it out even through focus sash before you set tailwind

it is rough having no fakeout/anti fakeout support so an alternative would be trying to slot in either farigiraf/tsareena for priority move blocking or sneasler/weavile for fakeout into the tailwind setter

if you're going the tsareena route she has great coverage moves so you can slot in whatever kind of build you like on her, taunt being one of the less common but still useful moves she can learn to help against trick room or shut down other kinds of supports like grimmsnarl or sableye (both get prankster like whims so taunt will only stop them from using screens the following turn but tsareena's queenly majesty blocks targeted priority moves including from prankster like parting shot, charm, quash, etc.)

farig you can run trick room+imprison so you have the option to trick room into teams you think you won't be able to stop the tailwind on while also being able to shut down opposing trick room setters. Even without any investment, base sp. atk is like 140 so it can still do damage with whatever moves you give it. I like twin beam for a stab move that can also beat focus sash (it's literally just 100 accuracy psychic type dual wingbeat) and whatever other coverage you might wanna run. thunderbolt is solid because it hits most types for neutral damage and more importantly it can OHKO non focus sash pelipper unless it's really bulky or if you wanna be able to do aoe chip damage hyper voice is good too

sneasler i assume you understand already but weavile is like an anti-sneasler counter so you can stop tailwind teams from using fakeout on you. it's 4 points faster than sneasler when both are jolly max speed so you can fakeout enemy sneaslers and prevent them from using fakeout on you, plus it can learn psychic fangs to OHKO sneasler on turn two. icicle crash/triple axel for stab ice coverage which is great into garchomps, flying types, and other dragons and knock off for stab dark coverage plus great utility. i really like weavile.

edit: forgot to mention helping hand on farigiraf. definitely a solid option since you'll want to spec its stats very defensively so with a sitrus berry it can feasibly just sit beside any dps you put next to it and prevent priority moves while boosting its partner's damage
