So, I just went through Winoana's team, and I have Victory (Camerupt)'s Rock Slide that should take care of everything, HOWEVER, If the Pelipper lives, it could kill Victory with super-duper effective Water STAB, Cheetos (Lunatone), who is the only other Pokemon that knows a SE move that isn't underleveled (caught a Magnemite a while back), so should I bring him out and train him for Pelliper, it could probably OHKO him...
Your BLR should do the trick. Teach it Shock Wave and Ice Beam, and spam Ice Beam, when the Pelipper and Skarmory come out, use Shock Wave, assuming you still have it. Even if you don't, with Ice Beam, she is a joke. Besides, it is so weak that any good Pokemon, even those that don't have type advantages, can beat it (don't use something weak against it though). You can also use Magneton. It beats everything not named Altaria with Thunderbolt. Don't use it against Altaria because of it having Earthquake. I hope I've helped!
