I decided I'd come up with a little team, but I'm not sure how successful it COULD be, or will. Of course, a way of finding this out is to use it in a battle, or more. But, I decided I'd post a little RMT to get a few opinions, if that's ok. While it features UU/NU, this is for use in Standard.
----
The Line-Up:
----
The Lead:
(Hope to have replaced)
Froslass @ Focus Sash
Ability: Snow Cloak
Timid Nature
EVs: 4 Def/252 Sp.A/252 Spe
Spikes
Taunt
Destiny Bond
Ice Beam
Froslass is my suicide lead and Spiker. She's able to taunt other leads wanting to set up, use a status (I'm looking at you, Bronzong), or slower Pokemon that want to taunt her.
Destiny Bond is obviously the key to this set's success. Once it's time, Destiny Bond is used and relieve myself of a possible irritating threat.
The "Why hello there" sweeper:
Swampert @ Choice Band
Adamant Nature
Ability: Torrent
EVs: 104 HP/204 Atk/100 Def/100 Spe
Earthquake
Ice Punch
Stone Edge
Waterfall
A lot of people expect Swampert to be either a wall or tank on this team, so they're surprised when it hits hard thanks to Choice Band. Waterfall and Earthquake are nice hitting moves, along with the STAB they get. Ice Punch hits Grass types, Dragon and Flying most notably for this set. Stone Edge also hits Flying, but hits Bug as well.
The Special Sweeper:
Venusaur @ Choice Specs
Modest Nature
Ability: Overgrow
EVs: 236 HP/ 252 SpA/ 20 Spe
Leaf Storm
Sludge Bomb
Hidden Power Fire
Sleep Talk
This was originally Sceptile, but I found Sceptile couldn't hit hard enough. Venusaur really closes down some major threats, including CM Suicune, which is pretty much destroyed by a Leaf Storm. Most people opt for Hidden Power Ice to hit dragons, but I decided to go with Fire to make sure that Steel types couldn't instantly wall me, it also murders Scizor, Skarmory and Forretress. Sludge Bomb hits Celebi, and Sleep Talk is there so it can still see a use while asleep.
A tank and a half:
Registeel @ Leftovers
Careful Nature
Ability: Clear Body
EVs: 252 HP/ 100 Atk/ 156 SpD
Thunder Wave
Stealth Rock
Iron Head
Earthquake
Registeel sets up my Stealth Rocks, T-Wave for fast sweepers, and the two offensive moves to slowly chip away at the HP. Thunder Wave's keep purpose is so that fast sweepers don't get very far in the long run, especially with my two sweepers around. Registeel is essentially the Special Wall of this team.
A Kind-of Physical Wall:
(Hope to have replaced)
Hitmontop @ Leftovers
Impish Nature
Ability: Intimidate
EVs: 252 HP/ 72 Def/ 184 Spe
Rapid Spin
Toxic
Close Combat
Stone Edge
Hitmontop is the rapid spinner of this team. Able to get a Toxic off, he's able to prepare opposing tanks and walls a horrible time. Thanks to Intimidate, he can take Physical attacks quite well, making him a pseudo-wall of sorts. Close Combat and Stone Edge together gives quite a bit of coverage, Ghosts are hammered by Stone Edge and Toxic, Flying types suffer the same fate.
The Baton Passing Balloon:
(Hope to have replaced)
Drifblim @ Leftovers
Calm Nature
Ability: Aftermath
EVs: 80 HP/252 SpD/176 Spe
Baton Pass
Substitute
Hypnosis
Shadow Ball
Drifblim was a major help on this team. Its rather nice HP stat makes for good substitutes to pass around (most notably to Sceptile and Hitmontop). Drifblim has Hypnosis to make passing off Substitutes easier, and Shadow Ball for two reasons. The first, so that it isn't taunted to death. The second, so it can dispel of some Psychics and Ghost types that may try to stand in the way. Due to Sceptile being replaced, Drifblim's purpose is no longer full. So it could do with being replaced, preferably by another Spin-Blocker.

A concern when making this team was that there would be a type that wouldn't be covered, resisted and would be super effective against a Pokemon. Luckily, that hasn't been the case during the battles I've had with this team. But again, I would like to know where I can improve, what better fits a role, and more.

So, thanks for reading, be sure to look through the following post for how this team deals with threats, and rate.
