Need help fine tuning my BT team

[JoecoolsinceJohto]

So I've discovered the hard way that the Battle Tree is a few step above the Battle Maison in terms of difficulty. As of now my record is 10 wins.
My team as of now

Kommo-o
Ability: Soundproof
Item: Muscle Band (you do what you can with what you have)
Moves:
Sky Uppercut
Dragon Claw
Earthquake
Draco Meteor
I gave him something around 60 Attacks EV so Sky Uppercut 2HKOs more consistently. The rest have gone in Defense, and some in Sp Def. Currently thinking of dropping Draco Meteor for Dragon Dance, as DM is not doing so much more damage than Dragon Claw following the 60 attack EV. Also considering swapping Earthquake for Rock Slide, as my bane has been Charizards that set up.

Tapu-Fini
Item: Waterium Z
Moves:
Nature's Madness
Surf
Moonblast
Hydro Pump
Tape Fini has great survivability, so I'm considering reteaching her Aqua Ring, along with giving her Leftovers. Similarly to Kommo-o, I gave her few Special Attacks EV so her moves would 1HKO or 2HKO more consistently. Nature's Madness has not been very useful up to now.

Pheromosa
Recently got one via GTS, and tried her "out of the box" to see if she was viable, and was pleasantly surprised, as she fits the role of revenge killer I was needing. I'm still unsure of what I'm going to teach her, apart from U-Turn. Hi-jump Kick seems interesting, but I'm afraid the 10% miss and crash chance is going to haunt me at the worst moment.
Right now I'm leaning:
Jump Kick
U-Turn
Bug Buzz
Me First (or maybe Poison Jab)
Item: Focus sash
With most EV in Speed, some in Attack so the latter is Beast Boosted.

Is there anything better I could do?
Thanks for reading.

Fairy Types are a pain to that team, you don't have poison or steel moves and Pheromosa and Kommo-o are weak to that type. I would train a Metagross and buy him a Metagrossite for example.

Secondly, I would try to buy Kommo-o a Life Orb asap. But I understand your pain, BP are a pain to farm in the beginning. Also I would teach him Swords Dance instead of Draco Meteor.

I'm currently in battle 28th and my actual team is Garchomp, Porygon 2 and Mega-Metagross... My record is 37th so yeah... I'm struggling too.

When starting Battle Tree as a newcomer...any tips in terms of what three Pokemon I should start with, and there setup?
Any tips greatly appreciated. :)

My advice to you is to know your team's weaknesses and try to cover it up the said weaknesses. I also reccomend you to EV train your Pokemon and get the right nature.

I just recently had a 36 win streak with a mono dragon team. I have fought and beaten 2 mono ice teams. However, I've lost to a Mega Alakazam.

Here is my team:

Garchomp
Ability: Rough Skin
Item: Leftovers
EVs: Max Speed; Max Attack; 4 HP
Substitute
Swords Dance
Dragon Claw
Earthquake

Goodra
Ability: Sap Sipper
Item: Assault Vest
EVs: Max HP; Max Special Attack; 4 Special Defense
Dragon Pulse
Muddy Water
Sludge Bomb
Thunderbolt

Salamence
Ability: Intimidate
Item: Salamencite
EVs: Max HP; Half Attack; Half Speed
Roost
Dragon Dance
Double Edge
Earthquake

I know it's not the best team for the Battle Tree, but I've made it pretty far.
