Well, there are quite a few, but assuming you have more than one Pokemon left, it means you can switch out from certain threats like Mamoswine & Skill Link Cloyster.
Latios: Pursuit Scizor, Weavile & T-Tar; Scarfed Weavile (it happens); Sucker Punch Toxicroak
Landorus-T: Ice Shard Mamoswine & Weavile
Rotom-W: nothing too obvious. Breloom would be a threat, but with Choice Scarf you can escape with Volt Switch.
Otherwise, Choice Scarf Skill Link Cinccino with Bullet Seed will outspeed Rotom-W, and anything with Chlorophyll on a sun team, like Lilligant, Venusar & Shiftry.
