RMT-A random team I made.

[Lightning-Z]

Sorry, in advance if I made a few mistakes. Also let e note that this team is for competitive and Wi-fi.

Crobat
item:Leftovers
EVs: 160hp/132atk/216speed
Nature:Jolly
Moves:
Ariel ace
hypnosis
u-turn
Zen headbutt

I actually owe thanks to Sanrgreal(A friend of mine) for helping me notice that Crobat has a crap sp.atk stat.

So thanks! The way he's used is almost like a scouter. He puts to sleep a poke and u-turns to counter. Also if Gengar leads, he'll be surprised by zen headbutt and so will Heracross. OHKO them easily. He'll usually be my last poke in a battle and finish the job.

Porygon-Z
abillity:download
item:choice scarf
EVs: 252speed/252spatk
Nature:Modest
Moves:
Ice beam
T-bolt
tri-attack
dark pulse

Obviously he has download and is my Special sweeper. It's not normal that you see this guy scarfed but he is an incredible sweeper. Faster tha scarfed adamant chomp gives him a great advantage! Not to mention he is sturdier than you think. This little buddy can switch into anything thanks to crobat.

Blissey
abillity:Natural cure
item:Leftovers
EVs: 204hp/252def/48spatk/4spdef
Nature:bold
Moves:
ice beam
softboiled
seismic toss
T-wave

She is your standard special wall. Usually I tinker with T-wave and change to aroma therapy or something else. So far T-wave has worked fine.
-----
Weavile
Abillity:pressure
Item Choice band
EVs:252speed/252atk/4hp
Nature: jolly
Moves:
Ice shard
night slash
ariel ace
brick break

Your pretty standard Choice band weavile. Ice shard is obviously a must and jolly is great for out speeding those sweepers so I can at least get one clean hit. I could change band for something else, but band has worked just fine.
-----
Starmie
Abillity:Natural cure
item: wise glasses
EVs: 160hp/216speed/132spatk
Nature:timid
moves:
surf
t-bolt
recover
rapid spin

The standard spin starm. I only picked wise glasses for the fact that a bit extra omph on damage would be helpful in a battle. Other than that, very sturdy and fast. Does the job right. I also use it as a sacrafice poke. If I think the situation got bad I take this guy out to give me time to counter.
-----
Infernape
Abillity:blaze
item: life orb
EVs: 24atk/252speed/232spatk
Nature: naive
Moves:
Close combat
flamethrower
grassknot
HP (Ice)

This guy is gold on my team! I love this guy with all my heart for saving me from loses. This is Mixape, an incredible wall breaker if I say so myself. He is there for swampy, blissey, skarm, milotic and any other pokes that stand in the way. He is faster than adamant SD chomp and jolly SD chomp so HP ice takes care of them. The same with other dragons. Sometimes scarf chomp doesn't finish the job against Nape and at his expense thanks to life orb kills chompy. So he is powerful indeed.

Give me your suggestions on this team and let me know what you think. I plan to make this my permanant team, so I will need all your suggestions. Thanks in advance.

if you're going to use a choice band, i recommend using pursuit over aerial ace on weavile. this is because aerial ace pretty much will only hit heracross, who will most likely be switching out anyways. if u want to keep aerial ace, then i'd use an expert belt over choice band. also, pursuit can often revenge kill for u, or nab quick kills on gengar.

don't know man, your team is incredibly frail. how are you going to switch into anything? needs some BIG changes imo.

first off, P-z's not doing anything on this team. i would switch it for a ground type such as mamo or garchomp for defensive typing.

metagross would probably be a good idea too. it'll work well with crobat.

this team needs some variety quite badly (sorry if i sound rude). you don't need a team of pure sweepers. sweepers are only really good late game and before that it would be better for you to use bulky wall breakers or walls as well as general counters to threats. right now, you're depending on revenge killing and that means sacrificing one of your team members.

Oh! You don't sound rude at all. I too have noticed the team to be quite frail. Though it has won quite a few battles, they've al been very close.

I actually tried a sturdy wall like bronzong and forrtress. I've also tried a metagross on the team. It works alright, but not as geat as the team I've posted. Maybe I wasn't using them right.

AZ do you really need 4 Ice type moves. Maybe give swap Ice beam on porygon-Z if you keep it for HP something.
