Team 1

Weaknesses:
Poor Gastly matchup, pretty hazardous if Twinkle Tackle.
Diglett gives you serious problems if given a chance to introduce itself and remove Mareanie, which seems to be your only defensive backbone.
Abra, while not as dangerous as Gastly, can wreck havoc easily.
Team REALLY weak to Magnemite, being Analytic and Magnet Pull variants very hard to deal with.
Doduo matchup pretty relies on both Amaura and Vullaby, being Amaura not a great Flying answer and needs to be introduced to revenge kill it.

Suggestions:
Swap Pawniard with Ferroseed to both apport Stealth Rock and form a solid defensive backbone with Mareanie which can better handle both Abra and Gastly, preferably Berry Juice. Also, patches up a Diglett weakness.


Tean 2:

Weaknesses:
Worrying lack of good Flying answers.
Lack of overall power.

Suggestions:
Onix over Cottonee gives you a decent Flying check, as well as Sstealth Rock, which means you have to put Spikes on Ferroseed. The advantage of doing so means that both Mienfoo and Pancham can break each other's checks and counters easily.
Change Mienfoo set to Scarf. In a type spam, you look for you type core to break, and Mienfoo has the ability to give you a potent and fast wallbreaker.
Spritzee over Larvesta fits best, forming the infame FerroSpritz core that blanket checks a big chunk of metagame, as well as better managing Shellder which is hazardous. Coverage on Spritzee may be necesary if you have some trouble dealing with certain threats.


Team 3:

Weaknesses:
Diglett makes a good run over this team, meaning that a bad predicted move on Chinchou is fatidic to lose your only decent Ground-check.
You may want have a better matchup against Croagunk, as its different sets can catch you off guard if not predicted correctly.

Suggestions:
Foongus over Chinchou gives you a decent defensive pivot that imrpoves your Ground-type matchup, and you can also decide if run HP Psychic to improve your Croagunk matchup.
Another suggestion, if you don't like Foongus on the team, feel free to take advantage of Veils and run Snivy as a wallbreaker with Knock Off, to improve Spritzee capabilities while boosting up.
Choosing one of the former suggestions, change Iron Head by Zen Headbutt on Scraggy.


Team 4:

Weaknesses:
Pretty solid team, but you may need a better Flying check, as Magnemite cannot freely switch in against many birds.

Suggestions:
Sturdy Onix over Foongus or Staryu, though you may need more offensive pressure, so keeping Staryu is more recommended. Doing this means that Diglett can run Sucker Punch, freeing a moveslot to be more flexible.
