My first team - Standard OU Single 1v1

[Houndoom88]

This is my first team and I need your opinion on it, as I don't know much about competitive battling.
So here we go

Skarmory @ leftovers
Ability: Keen Eye
EVs:252 HP / 252 Def / 4 Sp. Def
Nature: Impish
- Spikes
- Stealth Rock
- Roost
- Roar

It is useful for Spikes/Stealth rock support and to be hit by a physical attack.

Bronzong @ Light Clay
Ability: Levitate
EVs: 252 HP / 152 Atk / 8 Def / 96 SpD
Nature: Impish
- Reflect
- Light Screen
- Gyro Ball / Earthquake
- Explosion

It will set up the dual screen before a bulky offensive Pokemon comes in.

Tyranitar @ Lum Berry
Ability: Sand Stream
EVs: 4 HP / 252 Atk / 252 Spe
Nature: Jolly
- Dragon Dance
- Rock Slide
- Crunch
- Fire Punch

With Reflect/Light Screen it will do a Dragon Dance easily, while being protected by Lum berry and then star pwning.

Gyarados @ Life Orb
Ability: Intimidate
EVs: 252 Atk / 4 Def / 252 Spe
Nature: Adamant
- Dragon Dance
- Waterfall
- Stone Edge
- Earthquake

Another bulky sweeper that has a lot of Attack.

Gengar @ Life Orb
Ability: Levitate
EVs: 4 Def / 252 SpA / 252 Spe
Nature: Timid
- Shadow Ball
- Thunderbolt
- Focus Blast
- Psychic

A nice special sweeper that can be used to avoid a Rapid Spin by the opponent.

Scizor @ Choice Band
Ablility: Technitian
EVs: 248 HP / 252 Atk / 8 Spe
Nature: Adamant
~ U-turn
~ Bullet Punch
~ Superpower
~ Pursuit

Priority + Pursuit is a nice response to speedy, vulnerable targets.

Thanks for reading this post, and as I said, I don't know much about competitive so forgive any sucky choice of me :)

Please expand your descriptions as they're definitely not up to rule 3:

3. Have some actual words in your post beyond your six Pokemon and their moves. Not following this makes your post quite boring to read and rate. All Pokemon should have a good reason for being in your team anyway, so why not post that reason? If you are having trouble with this one, start by giving an explanation for each team member. Why are they there? What role do they serve? How do you get them in? Then, give an explanation of how you would open with the team and how you would go about using it. All of these things help people rate your team and allow us to offer more helpful advice.

This does not mean add one sentence saying "Standard x" or "all-around awesome" after each Pokemon. If you put thought into making the team, you can put thought into posting it.

Take a look at the RMT archive to see what kind of descriptions we are looking for. PM me the fixed descriptions and I'll unlock this thread.
