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 wave 
 8.Meditite (35): Confusion, Calm Mind, Hi Jump kick, Strength 
 9.Klink (36): Gear grind, Mirror Shot, Charge beam, Autotomize 
 10, Heatmor (41): Slash, Cut, Flame burst, Bug bite 
   
 I started the game at episode 13, so I don't know if I can get abra or other psy pokemons others use 
   
 What do you think I can do? 
   
 Thank you all
