So, I can't beat aya. I tried a lot of strategies, even leaving her muk alive and focus on the other pokemons she has.
This is my team:
1.Charizard (45): Dragon Rage, Wing attack, Flame burst, Flare blitz
2.Persian (39): Cut, Slash, Bite, Fake out
3.Panpour (42): Acrobatics, Scald, Brine, Water Gun
4.Graveler (45): Rock Smash, Rollout, Earthquake, Bulldoze
5. Pachirisu (42): Super Fang!, Discharge, Swift, Charm.
6.Sunflora (45): Petal Dance, GrassWhistle, Giga Drain, Leech Seed (I usually don't bring her to battle Aya)
7.Muk (40): Sludge Bomb, Fling, Screech, Sludge wav
