OU Team - Major Help!

[TheBroken]

Ok, I have recently built this team. I'm decent at teambuilding, but definitely not great so I need help. This team has done decent, but it could be better. So, here's the team.

Jirachi@Choice Scarf
Nature: Adamant
EV's: 48hp/252atk/208Spe
- SR
- Iron Head
- Ice Punch
- Fire Punch

This is my lead. SR to set, Iron Head to Flinch hax my opponent. Fire Punch is so I'm not completely walled by steels and Ice covers those annoying dragons for my team.

Rotom-H@Leftovers
Nature:Bold
Ev's: 252hp/168def/88spe
- Discharge
- Will-O-Wisp
- Overheat
- Shadow Ball

This is one of my support pokemon. Will-O-Wisp stops physical pokemon that could be potentially a threat. Discharge is there to damage with a 30% chance of paralysis. Shadow ball covers ghosts, and Overheat for steels, like Scizor.

Gyarados@Leftovers
Nature:Impish
Ev's: 156hp/72atk/96def/184spe
- Taunt
- Dragon Dance
- Waterfall
- Stone Edge

Bulkygyara. This guy stops phazers from switching me. He can also act as a defensive wall and attacker with this EV spread, and OHKO many pokemon. Covers me from pokemon like Scizor, Lucario, and possibly other Gyara's.

Blissey@Leftovers
Nature:Bold
Ability: Natureal Cure
Ev's: 24hp/252def/232spD
- Softboiled
- Aromatherapy
- Thunder Wave
- Ice Beam


Blissey is my special wall. Protects against really almost any special attacker. Great at stopping physical sweepers that switch in with Thunder Wave then picking them off with the rest of my team.

Gengar@Choice Scarf
Nature: Modest
Ev's: 4def/252spA/252spe
- Thunderbolt
- Shadow Ball
- Focus Blast
- Explosion

My main special attacker. He can kill really anything in his way with high special attack with massive speed. He's able to outrun almost everything in the metagame and can hit back hard. Thunderbolt covers waters, shadow ball for ghosts like opposing Gengar, or Rotom. Focus Blast can get rid of Umbreon or steels, and explosion to try to kill anything that's a problem.

Lucario@Life Orb
Ability: Steadfast
Nature: Jolly
Ev's: 4hp/252atk/252spe
- Close Combat
- Crunch
- Extremespeed
- Swords Dance

My main physical attacker. He can set up and sweep anybody during late game if there aren't any counters for him. CC kills steels and pokemon like TTar. Crunch gets rid of the ghosts and psychics. Extremespeed is priority and can hit pretty hard with 80 base power. Swords Dance is self explanatory. Just to double my attack, making it much easier to set up a sweep.


This team needs major help, so please RMT!

Locking the thread due to this rule

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.
