Something that I thought up, because Altaria seems pretty usable in this meta.
4 Holon's Castform
3 Wooper d
3 Quagsire d
4 Swablu d
4 Altaria GE
4 Celio's Network
4 Holon Mentor
2 Bebe's Search
2 Roseanne's Research
2 Castaway
4 Buffer Piece
2 Cessation Crystal
2 Potion
4 TV Reporter
4 Grass
5 Water
4 DRE
1 Scramble
1 Cyclone
Strat: Castform to start (OMG crazy I know right?). Attack with Altaria's Cotton Cloud, which reduces damage from Evolved Pokemon by 30. Recycle Buffer Pieces strategically with Quagsire.
Fun fact: Cotton Cloud+Buffer Piece = Gallade needs to flip over 1 prize to do 10 damage. Sonic Blade only does 30.
