This is my first RMT for a new kind of tier, RU (Rarely Used) I believe. I have been working on this team for a while, and haven't succeeded in making the official yet, so without further ado, here is the team.
Omastar:
Omastar @ Leftovers
Nature: Bold (+Def, -Atk)
Ability: Shed Shell
Ev's: 248 HP / 252 Def / 8 SpD
Moves:
Stealth Rock
Spikes
Surf
Ice Beam
All though Omastar isn't a very known defensive Pokemon, he is paired with moves that have a high supporting role. The main array is to switch into something that doesn't threaten Omastar, (Fire, Flying, Etc. Etc...) and set up spikes, and stealth rock. This makes him my lead/supporter. Surf adds some STAB to his move-set, and allows him to look normal. Omastar is my Premiere lead, and supporter, so that he can quickly get me a entry hazard set up.
Electivire:
Electivire @ Expert Belt
Nature: Adamant (+SPa -Atk)
Ev's: 4 HP / 252 Atk / 252 Spe
Moves:
Thunder Punch
Ice Punch
Cross Chop
Earthquake
Electrivire is my Wall breaker. with his coverage, and STAB, this allows him to make critical moves, at critical times. He does the most damage against walls, and was a great recommendation. He does the main damage for my team. He is my breaker/Support/Sweeper. This is my all-star.
Elektross:
Elektross @ Life orb
Nature: Adamant (+SPa -Atk)
Ev's: 4 HP/ 252 ATK/ 252 SPA
Moves:
Protect
Hidden Power (Ice)
Thunder
Flamethrower
Elektross is my main sweeper. He does the electric damage, to counter rain, and he does the poison damage for an extra hit. He comes in, and can become a breaker, using Volt Switch to slowly break down walls, working in co-op with Swellow for this. He is the secondary to Electrivire, and can do the damage needed. He is my secondary All-Star, I guess you could say he is the bench warmer or runner up in my team.
Swellow:
Swellow @ flame orb
Nature: Jolly (+Spe -Atk)
Ev's: 4 HP / 252 Atk / 252 Spe
Moves:
Facade
Brave Bird
U-Turn
Quick Attack
Swellow is my wall defense. He comes in, and slowly weakens walls. He can quickly attack, and get his butt out of there. He is my biggest defensive core, and one of the best options for my team in my opinion. Swellow is how Minun, and Plusle get their sweeping abilities, without Swellow, they are just another Pokemon on my team.
Dugtrio:
Dugtrio @ Life Orb
Ability: Arena Trap
Nature: Jolly (+Spe -Atk
Ev's: 4 HP / 252 Atk / 252 Spe
Moves:
Earthquake
Sucker Punch
Stone Edge
Substitute
Dugtrio helps counter Blissey, he can jump in, and KO her without issues. He can quickly attack weaknesses, and occasionally sweep. Because of his STAB he can OHKO Pokemon like Houndoom, Blaziken, and Toxicroak. This is especially useful when I need a quick attack to get rid of a threat. This gives my team some sort of usefulness.
Qwilfish:
Qwilfish @ Life orb
Ability: Swift Swim
Nature: Jolly (+Spe, -Atk.)
Ev's: 252 Atk / 4 Def / 252 Spe
Moves:
Swords Dance
Waterfall
Explosion
Poison Jab
Qwilfish is the same thing that Omastar is. Bulky enough to get in, do his job and get out. The idea with this set is to turn him in on something that isn't effective against him, then just use supportive moves. He helps if Omastar faints, he can take his role. This Pokemon is another Essential to my team.
This is my team, I hope you can give me some Ideas, and remember that this is a RU team. If you do recommend a Pokemon, can you give me some basic info about him, so I can get a general idea of what you are trying to say.
Plusle:
Minun: (Possibly come back... If I can't get a good sweeper for my team.)
