[RATE MY TEAM] pls help me to fix my vgc17 team

[hellhunter91]

hello guys! I'm building and testing my vgc17 team from two days, i think there is lot of potential and i really like how i play with it, but i need to know from you (yeah you are more expirienced than me) if there is any problem or if i need to fix something in my team. I start to build it from golisopod and than i came up with this, here you are:

Golisopod @ Assault Vest
Ability: Emergency Exit
Level: 50
EVs: 252 HP / 100 Atk / 156 SpD
Brave Nature
- First Impression
- Aqua Jet
- Poison Jab
- Liquidation

AV is for make him bulkier and allow to survive more hits, poison jab for the fairies.

Garchomp @ Lum Berry
Ability: Rough Skin
Level: 50
EVs: 252 Atk / 4 SpD / 252 Spe
Jolly Nature
- Rock Slide
- Earthquake
- Dragon Claw
- Protect

probably i'll change rock slide or dragon claw for ironhead. Lum berry is for recovering from status like burn.

Xurkitree @ Air Balloon
Ability: Beast Boost
Level: 50
EVs: 252 HP / 252 SpA / 4 SpD
Modest Nature
IVs: 0 Atk
- Discharge
- Thunder
- Protect
- Tail Glow

air balloon is necessary to avoid my garchomp EQ, the rest of the set is pretty standard, thunder over thunderbolt to make big damage in the rain

Tapu Bulu @ Life Orb
Ability: Grassy Surge
Level: 50
EVs: 252 HP / 252 Atk / 4 SpD
Adamant Nature
- Horn Leech
- Wood Hammer
- Protect
- Stone Edge

I don't really know wich is the best item for tapu bulu, i first used grassiumZ but i changed in favor of the life orb to have more power output and kill tapu lele. The problem is the recoil... stone edge is for the flyng type.

Pelipper @ Flyinium Z
Ability: Drizzle
Level: 50
EVs: 4 HP / 252 SpA / 252 Spe
Timid Nature
IVs: 0 Atk
- Tailwind
- Scald
- Protect
- Hurricane

the big surprise of my team, is fast and powerful, but i don't know if the item is the right one. pretty solid i used the Aaron Zheng spread.

Togedemaru @ Sitrus Berry
Ability: Lightning Rod
Level: 50
EVs: 252 Atk / 4 SpD / 252 Spe
Jolly Nature
- Thunderbolt
- Spiky Shield
- Fake Out
- Zing Zap

last but not list the lighitning rod user. I chose thunderbolt over nuzzle as a way to use the possible bonus in sp. attk. The big problem is that i haven't a steel move so i was thinking to change him with marowak.

the main strategy is to use rain and tailwind with the help of the grassy terrain. I started building from golisopod, i wanted to cover his weaknesses so i added tapu bulu to cover his rock weakness and garchomp for the electric one. Than i started to think about my way to control speed, i decided to run the tailwind because golisopod has a lot of priority and other pokemon was pretty fast, so the TR was pretty hard to use. First i wanted to use crobat, but i changed in favor of pelipper for two reason: 1 his new ability help me to nerf the fire moves that threaten tapubulu 2 he is very fast and pretty bulk and he can be helpful against fire pokemon and grass\bug. Next step was to make full use of the rain and i decide to add Xurketree with thunder (can't miss in rain). After that i was looking for some good partner to protect pelipper and i decided to use a lighting rod so i put togedemaru because of his steel typing.

lead: garchomp xurketrre\ pelipper xurketree \pelipper garchomp \tapubulu pelipper\ pelipper togedemaru.

garchomp is a good partner for xurketree because i can spam discharge and EQ thanks to the air balloon. Also Pelipper is good with Xurketree because of the rain. The rain also nerf fire so the lead tapu bulu- pelipper is pretty solid.
