This is my Top 6 Lineup.  It features a lot of pokemon that work together with each other to maintain its performance.  I like the tank-type Pokemon, as well as the utility pokemon a lot, and my team supports that.

 

Name:  Charizard

Type:  Fire/Flying

Gender:  Female

Nature:  Adamant

Ability:  Blaze

Item:  Salac Berry

Move Set:

Overheat

Earthquake

Belly Drum

Rock Slide

 

Strategy:  A big hitter here.  "Bellyzard" is just too good not to use on this team.  If he gets Baton Passed out, then prepare for quite a beating.

 

Name: Umbreon

Type:  Dark

Gender:  Female

Nature:  Bold

Ability: 

Item:  Quick Claw

Move Set:

Toxic

Mean Look

Confuse Ray

Screech

 

Strategy:  Use Confuse Ray, then Mean Look.  Toxic is next, then Screech them to death.  Screech increases the damage done by Confuse Ray, which will KO any pokemon soon enough due to the Poison.

 

Name:  Ninjask

Type:  Bug/Flying

Gender:  Male

Ability:  Speed Boost

Nature:  Timid

Move Set: 

Swords Dance

Silver Wind

Baton Pass

Double Team

 

Strategy:  Your typical Baton Passer.  Ninjask is simply amazing because of this ability.  Any of my Poke'mon can become a tank when this thing is used.

 

Name:  Blissey

Type:  Normal

Gender:  Female

Nature:  Bold

Ability:  Serene Grace

Item:  Leftovers

Move Set: 

Softboiled

Counter

Aromatherapy

Ice Beam

 

Strategy:  Your typical healer, with Serene Grace increasing Ice Beam's chances.

 

Name:  Shiftry

Type:  Grass/Dark

Gender:  Male

Nature:  Modest

Ability:  Early Bird

Item:  King's Rock

Move Set: 

Rest

Faint Attack

Swagger

Double Team

 

Strategy:  Thanks to Early Bird, Shiftry wakes up from Rest in 1 turn instead of the usual 3.  With Double Team, this Pokemon could be the most powerful Tank/Sweeper on the team!  I'll use Double Team, and when the HP gets low, I'll just Rest back the HP.  If I play a Fire Pokemon or something that kills Shiftry, I'll just switch to Umbreon (it can handle almost anything).

 

Name:  Dragonite

Type:  Dragon/Flying

Gender:  Male

Nature:  Modest

Item:  Focus Band

Move Set: 

Haze

Substitute

Focus Punch

Outrage

 

Strategy:  A peculiar Poke'mon, but it helps with Haze.  Substitute + Focus Punch is just mean with Dragonite's g0dly Attack Score.  Outrage is tEcH.
