Can someone please help me beating Noel. I can reach the point of beating 4 of his Pokemons but after that it's like impossible to win. That stupid "Swellow" and "Porygon-Z" of his are destroying all my Pokemons. This is my team and I spent a lot of time making it as it is right now. I'm sure they will get me through this: 
Swampert (Lonely/Damp) Lv54 
-Rock Slide 
-Sludge Wave 
-Earthquake 
-Muddy Water 
Gothitelle (Gentle/Competitive) Lv50 
-Charge Beam 
-Psychic 
-Dark Pulse 
-Heal Block 
Arcanine (Hardy/Flash Fire) Lv51 
-Crunch 
-Outrage 
-Flamethrower 
-Close Combat 
Ampharos (Modest/Static) Lv50 
-Power Gem 
-Confuse Ray 
-Thunder Wave 
-Discharge 
Togekiss (Timid/Super Luck) Lv54 
-Yawn 
-Aura Sphere 
-Magical Leaf 
-Air Slash 
Victrebell (Adamant/Chloryphyll) Lv50 
-Leaf Blade 
-Knock Off 
-Nature Power 
-Growth 
Togekiss's Yawn helped me making Porygon-z go to sleep and I finish him with Arcanine's close Combat, and I can thunder wave Swellow before he uses the Flame Orb. Other than that I die with Cinccino or Girafrig. 
I need help please. 
Edit: YAY! I won after the 12th time of losing. I used Sludge Wave to change the field and got 2 critical hits with Swampert's Earthquake against Porygon and Wigglytuff ^^ 
I won with Victribell's Growth and Nature Power against Clefable.
