My First Try 2.0 :)

[Frappuccino]

Lead:

Leftovers
Moves:
-Toxic
-Confuse Ray
-Protect
-Dark Pulse

Ability/Nature:
Synchronize/Calm(+SpD -Atk)

Tactic:
I lead with Umbreon. I poison the opponent, then confuse them. I then do damage with Dark Pulse and Protect to keep the poison going. I keep using Protect and Dark Pulse (vary between the two) until they faint.

Annoyer:

Leftovers
Moves:
-Substitute
-Swagger
-Thunder Wave
-Foul Play

Ability/Nature:
Prankster/Impish (+Def -SpA)

Tactic:
Reallllllllyyyyyy cheap tactic, I know. But it works and i'm a noob so it's really handy for me :D
I use swagger or thunder wave (depending on opponents type), and then the other one i didn't use first and then I go into substitute. As long as I last in substitute I keep hitting the opponent with Foul Play until my sub breaks and then I go back into Substitute.

Attacker:

Choice Specs

Moves:
-Shadow Ball
-Focus Blast
-Thunderbolt
-Hidden Power (Water)

Ability/Nature:
Levitate/Timid (+Spe -Atk)

Tactic:
There isn't really a tactic with my Gengar, his main purpose is just to be an attacker and attack. I chose his moves of all different type and made sure there were a few 100% acc ones. I chose Hidden Power Water because I don't have any water types or water type moves on any other of my Pokemon.

The Spiky Tactic Thingy:

Leftovers

Moves:
-Giga Drain
-Toxic Spikes
-Spikes
-Rapid Spin

Ability/Nature:
Sturdy/Bold (+Def -Atk)

Tactic:
When I send him out I use 1 Toxic Spike and then just spam with Spikes until i'm not allowed any more, then more Toxic Spikes until i'm not allowed any more of THEM. and then Giga Drain to get back health and do damage. I use rapid spin when someone has set up spikes or stealth rock on MY side.

Wall(I think):

Leftovers

Moves:
-Seismic Toss
-Wish
-Heal Bell
-Protect

Ability/Nature:
Natural Cure/Impish (+Def -SpA)

Tactic:
Honestly, I don't know what the hell to do with Blissey, but my friend who showed me competitive battling said she was good so... idk. But what I'm doing with her is bringing her out as a defensive mechanism, healing and stalling whilst doing damage with Seismic Toss. I don't know if this is the correct way to use her but so far she's not been that useful...

2nd Attacker:

Charizardite X

Moves:
-Solar Beam
-Dragon Pulse
-Earthquake
-Fire Blast

Ability/Nature:
Blaze/Timid (+Spe -Atk)

Tactic:
I added Charizard to the final position of my team to once again do damage just like Gengar, I couldn't expect Gengar to do all the damage since he had no healing moves or leftovers so I needed a 2nd attacker and thought Charizard would fit it perfectly :) I made sure again to have every attack a different type and some with 100% acc. And so far he's proven to be really useful.

_______________________________________________________________

So there is my team, bear in mind this is my first ever team and I started competitive battling yesterday so I'm still trying to get a grip of the basics but I'm getting there :D I'd love to have constructive criticism and you can be as bossy/mean as you want xD ! There is also loads of room for improvement so if y'all could direct me down the right paths then maybe I could become really good at competitive battling :)

Hello, im also new but i will try to give you a few suggestions.
First of all-and pretty important-you should wrote the EVs of your Mons Down.
Second,use SR over Toxic Spikes, SR is so important this Meta. And dont use Giga Drain, with its spatk stat it doesnt do enough damage, everybody Would just Switch in a mon that boost in Front of this thing.
Third, I Hope You meant Zard Y. That are all Special attack Moves (expect EQ, but that doesnt do much damage) and Zard X is a Physical attacker. I Would use ZardY with Roost/Focus Blast instead of EQ.
So, that was it, i Hope i helped you.

Ferretress with his spikes set has declined in usage due to the amount of defog users now availible to battlers of the current metagame (curse you mandibuzz!!!)

 

[Frappuccino]

Thanks guys :D Yeah I changed Charizard to Y and replaced Blissey with this:

Leftovers

Moves:
-Wish
-Dazzling Gleam
-Protect
-Cotten Guard

It has Sweet Veil and Calm nature :D

and its to stall :)

 

[Frappuccino]

Bump!

Change Forretress's set to this:
Forretress @ Lefovers
Overcoat
252 HP/ 252 Def/ 4 Atk
Relaxed Nature
-Stealth Rock
-Rapid Spin
-Volt Switch
-Gyro Ball/Spikes

Stealth Rock is one of the best moves in the game, as it breaks sashes, adds up switch in damage, and affects almost every pokemon. It is far superior to Toxic Spikes. T-Spikes are easily removed with all the Defoggers running around, and the fact that any grounded poison type removes them is a bummer. Also, you Klefki set (which you should change) relies on T-Wave and your Umbreon, which relies on Toxic, are hurt by only having one layer of T-Spikes up. Volt Switch is far superior to Giga Drain. Giga Drain does no damage with his paltry SpAtk, and Volt Switch isn't for damage, but for momentum when you suspect the opponent will switch, or to let Forretress take an attack to get a safe switch in. Gyro Ball gives him a (minor) offensive presence, and can damage a few setup sweepers, while Spikes does extra damage for Pokemon switching in. Overcoat is better than Sturdy, since he won't get OHKOed if you make sure to not leave Forretress in against a strong special attacker or a Fire type move, and Overcoat makes him immune to Spore.

Also replace Dark Pulse with Foul Play on Umbreon. He has horrible attacking stats and Foul Play does damage based on your opponents attacking stat, making sure he isn't complete setup bait.

You need to add evs.

 

[whoyoufinnatry]

Please try to change the OP when you change a pokemon, and include the changed pokemon on a different section showing your old pokes or a teambuilding process where you can explain why you decided to change your poke. It makes it easier to those newly reading the post as they can see the current team being utilized and trying to help from there.

With that in mind, I'd like to mention the option of switching your Slurpuff to a Sylveon.

Sylveon proves to be the stronger Sp. Def cleric that you seem to fill the role with in Slurpuff. Its HP, SpA, and SpD are clearly superior than Slurpuffs so it can Wish pass more health, has the stronger ability in Pixilate so it can hit stronger with Hyper Voices that can also hit through subs if need be, and ends up being more useful as it can use Heal Bell if your pokes are status as your Umbreon isn't running it.

Also I think you should switch up your Mega Charizard Y back to Mega Charizard X running this set:

Charizard@Charizardite X
Nature: Jolly
Ability: Tough Claws
EVs: 252 Atk/252 Speed/4 HP

-Dragon Dance
-Flare Blitz
-Dragon Claw
-Earthquake/Roost

I think your team really needs a strong Physical Attacker which Zard-X fills in quite nicely as it can set up on a large portion of pokemon and proceed to sweep, particularly during late game. You can decide to run either Earthquake or Roost depending what you prefer, be it better coverage so you can hit threats such as Heatran which you would otherwise be unable to touch or reliable recovery in the case you took too much damage from switching in on a move/hazards.
