[REQUEST] I need advice on my VGC 2016 Team

[OdysseusHestia]

Alright as obvious by the title I built a VGC 2016 Team that I need some advice with. I built in in Showdown and I'm experiencing some difficulty continuously winning battles. I do win more than I lose though. I knew the main pokemon I would be facing would be P-Kyogre, P-Groudon, and Mega- Rayquaza so I tried to build a team good enough to get rid of them quickly. The Team is fast past trying to get rid of as many pokemon as possible gaining an advantage over the opponent. I'm pretty much an amateur to making teams so bear with some of my stupidity especially when it comes to EV spreads. (I don't know how to do Gifs so Its not going to look cool)

First Pokemon I want to start off with is:


Palkia @ Lustrous Orb
Ability: Pressure
Nature: Timid
EVs: 252 Sp. A / 4 SpD / 252 Sp

• Earth Power
  
• Hydro Pump
  
• Spacial Rend
  
• Flamethrower/Protect (not sure which one)
  

The thought behind Palkia is help to get rid of P-Groudon. Earth Power should be able to 2HKO. Palkia can tank any most of the moves that most Groudon's have. Hydro Pump is there for STAB and Spacial Rend is there for the STAB along with the high crit rate and for pokemon that where water and ground type attacks would be insufficient. I also took note that my team that I didn't have enough Fire type attacks on the team. Fire attacks can work against Scizor, Ammongus, and Ferrothorn I noticed we might see alot in the meta. Protect is Protect. The EV spread was kinda thrown on there. I know that for sure I wanted to give Palkia enough Speed and Sp. Atk to be able to take P-Groudon. Speed is important when taking down Mega- Rayquaza or any Dragon type I may be facing.

Next Pokemon:


Zekrom @ Life Orb
Ability: Teravolt
Nature: Adamant
EVs: 252 Atk / 4 SpD / 252 Sp

• Dragon Claw
  
• Bolt Strike
  
• Rock Slide/ Volt Switch (Not sure which would be more effective)
  
• Protect
  

Zekrom's job is to sweep P-Kyogre with Bolt Strike which is OHKO. And also a Dragon Claw can take care of any dragon type. Rock Slide for type coverage. Flying types like Zapdos can become annoying when trying to use volt switch or Bolt Strike. Protect is protect. EV spread is all Atk and Speed. Trying to get as many out speeds as possible without losing to much power.

Next Pokemon:


Sableye @ Leftovers
Ability: Prankster
Nature: Impish
EVs: 252 HP / 116 Def / 140 SpD

• Fake Out
  
• Quash
  
• Foul Play
  
• Taunt
  

Sableye is basically what makes my team so powerful. Sableye uses Fakeout to stop anything that might stop hurt Zekrom or Palkia turn 1 and then the sweep begins. Zekrom then OHKO's P-Kyorgre. P-Groudon loses half of its life and then the Palkia faints it next turn. Taunt is to stop Xerneas from setting up and any other pokemon from setting up. Quash is to help get out speeds. I noticed that Palkia and Zekrom can be very slow. Foul Play can be very effective against the the contrary combo and Aegislash and Swords Dance Scizor and also very powerful physical attacking pokemon like P-Groudon. I didn't know the proper EV spread for Sableye so I just went half. I need some advice for that.

Next Pokemon:


Mega-Gardevior @Gardeviorite
Ability: Pixilate
Nature: Timid
EVs: 252 SpA / 4 SpD / 252 Sp

• Hyper Voice
  
• Ally Switch
  
• Psychic
  
• Hidden Power Fire
  

Mega Gardevior's job to protect my dragons and also sweep at the same time. I can ally switch to protect one of my pokemon. For example try using a dragon type atk on palkia and i ally switch protecting it. Plus its hard to predict and most people wont see it coming. Remember how I said that i didnt have many fire attacks :D Hidden Power Fire. OHKO Scizor and Mawile. Psychic for stab and Ammongus and Crobat which is heavy in this meta.

Next Pokemon:

Crobat @Black Sludge
Ability: Inner Focus
Nature: Jolly
EVs: 252 Atk / 4 SpD / 252 Sp

• Super Fang
  
• Cross Poison
  
• Brave Bird
  
• Heat Wave/ Haze
  

Crobat's job is to use Super Fang one pokemon that are harder to kill or just in case my sweepers are gone then out speed with the Brave Bird. Cross Poison for pesky Fairy types i.e. Xerneas. Brave Bird for sweeps and Grass types i.e Breelom(which i also seen alot of) and if cross poison isn't going to cut it. Heat Wave another Fire type attack I thought of adding for type coverage or Haze for Xerneas who likes to use Geomancy or any reduced stats against me. Jolly to out speed other Crobats and I didn't know what to do for an item.

Final Pokemon:

Empoleon @Assault Vest
Ability: Torrent
Nature: Quiet
EVs: 252 SpA / 4 Def / 252 HP

• Aqua Jet
  
• Scald
  
• Ice Beam
  
• Flash Cannon
  

Empoleon has one many games because he can tank many hits especially during late game and also can dish out some heavy damage with Flash Cannon and Ice Beam. Though he is slow Aqua Jet allows me to get priority for pesky focus sashed pokemon or pokemon that wont just die. Flash cannon helps against Xerneas and Fairy types and Ice Beam helps with many dragon, flying, grass types and there is alot of those in this meta. Assault Vest helps with Special Defense. The Rare typing can cause issues for the opponent. Steel resisting dragon types and Fairy.

I'm not willing to change Zekrom nor Empoleon any of the other pokemon would be fine.
