Pretty generic OU RMT, trying a few not-so-standard bits.

Aerodactyl @ Life Orb
Nature: Hasty
Ability: Pressure
EV's: 252Atk, 216Spe, 40Sp.Atk
~ Stone Edge
~ Earthquake
~ Fire Blast
~ Ice Fang

Lead. Doesn't tend to do much early on, but forces the likes of Weavile out. Also makes a fantastic late-game sweeper.

Blissey @ Leftovers
Nature: Calm
Ability: Natural Cure
EV's: 252Def, 252Sp.Def, 6Hp
~ Aromatherapy
~ Seismic Toss
~ Ice Beam
~ Softboiled

Lol Blissey. Aromatherapy because Mesprit needs it. .

Ursaring @ Life Orb
Nature: Adamant
Ability: Guts
EV's: 252Atk, 232Hp, 24Def
~ Return
~ Fire Punch
~ Rest
~ Sleep Talk

Killer wallbreaker. Whilst asleep, this thing is capable of 2HKOing Gliscor, Hippowdon, Skarmory, most Cresselia, the list goes on and on. Also serves as a pretty useful status taker.

Gliscor @ Leftovers
Nature: Impish
Ability: Sand Veil
EV's: 252Hp, 252Def, 6Spe
~ Earthquake
~ Roost
~ Ice Fang
~ Taunt

Typical walling Gliscor set-up, counters what it needs to. Taunt for shutting down incoming potential counters, as well as making up to a degree for my total lack of phazing otherwise.

Mesprit @ Choice Scarf
Nature: Bold
Ability: Levitate
EV's: 240Spe, 188Hp, 80Sp.Atk
~ Psychic
~ Ice Beam
~ Thunderbolt
~ Rest

Peculiar, no? I needed something that could counter Swords Dance Garchomp, Gyarados, Mixape and to an extent Electivire. Scarf Mesprit does a fantastic job of this; he outspeeds Gyara after a DD, as well as the other two whenever, and proceeds to OHKO them. He still beats Garchomp, even if it has a Yache Berry as an item, as SD'd Dragon Claw does around 70%. Ones that run both Outrage and Yache are problematic, but they can be finished off by Aero once they're locked in. EV's allow Garchomp OHKO with Ice Beam, outspeed max speed Jolly Weavile, and then just pumping the Hp. Rest because I prefer my counters to have some form of longevity, and Blissey can Aromatherapy the sleep away at a later date anyway.

Scizor @ Expert Belt
Nature: Adamant
Ability: Technician
EV's: 252Atk, 192Spe, 60Hp, 4Spe
~ U-Turn
~ Roost
~ Pursuit
~ Quick Attack

Finally, something that punishes Cresselia and Celebi. Priority is also a massive asset to any team. Considered a Specs Gengar here, just to give me a bit more special oomph on a predominantly physical team, but then I lose my Dragon resist. Considered Specs Lucario here, but then I can't touch Cress. Also stops Weavile from 6:0ing me.

@ Aero. Looks good
@ Blissey. Looks good (I don't know much about blisseys to rate em well.
@ Ursaring If you like to attack behind Sleeptalk alot you can use Facade, 140 attack + STAB is killer
@ Glisor Since 3 of your pokes are immune to sandstorm, you could give him that over roost to take advantage of Sand veil. Even without it's quite good.
@ Mesprit. Choice + Rest isn't a good plan. It'll wall but it's just stalling until a switch out. Maybe if you got Toxic somewhere on your team it'll do good. I'd say use Shadow ball or Water Pulse instead to cover Magenzone or Shedinja.
@ Scizor.

Adamant @ Swarm. Speed-boosting berry
252 ATK 252 SPD 4DEF
-X-scissor
-Iron Head
-Pursuit
-Quick attack/Swords Dance

This'll punish them better

Hmm. I'm going to make my replies in bold.

Aerodactyl @ Life Orb
Nature: Hasty
Ability: Pressure
EV's: 252Atk, 216Spe, 40Sp.Atk
~ Stone Edge
~ Earthquake
~ Fire Blast
~ Ice Fang

Lead. Doesn't tend to do much early on, but forces the likes of Weavile out. Also makes a fantastic late-game sweeper.

Looks good to me. If you're ever looking for something different, I know that Taunt+Stealth Rock also works wonders on Aerodactyl for a lead. Never used it myself, but I know someone who has to great effect.

Blissey @ Leftovers
Nature: Calm
Ability: Natural Cure
EV's: 252Def, 252Sp.Def, 6Hp
~ Aromatherapy
~ Seismic Toss
~ Ice Beam
~ Softboiled

Lol Blissey. Aromatherapy because Mesprit needs it. Shed Shell for Duggy.

Fair enough. There is no need for Shed Shell, really, because Dugtrio is decreasing in popularity. If you are really that afraid, pump some special defense ev's into special attack (enough to OHKO Duggy with Ice Beam). If you feel really lucky, run Blizzard over Ice Beam, as only 212 sp. atk is needed to OHKO Garchomps. Flamethrower works best with Grass Knot or Toxic if you want it that badly.

Ursaring is your main status absorber, so I'm not sure about the usefulness of Aromatherapy. Especially considering that your Mesprit is the only one who really needs it.

Ursaring @ Burn Orb
Nature: Jolly
Ability: Guts
EV's: 252 Atk, 252 Spd, 4 Hp
~Facade
~Fire Punch
~Earthquake
~Stone Edge
Killer wallbreaker. Whilst asleep, this thing is capable of 2HKOing Gliscor, Hippowdon, Skarmory, most Cresselia, the list goes on and on. Also serves as a pretty useful status taker.

Resttalk Ursaring doesn't live as long as one would hope, as his defenses are only mediocre. Life Orb is pretty useless when compared to Burn Orb, which uppers your attack by 1.5 (Guts ignores attack drops due to burn) AND prevents status. Doesn't last long, but completely destroys anything with Facade. Ursaring needs Jolly Nature to reach 229 speed, an important number that outspeeds no speed Gliscor, bulky Gyarados, and all the other walls you've mentioned.

Gliscor @ Leftovers
Nature: Impish
Ability: Sand Veil
EV's: 252Hp, 252Def, 6Spe
~ Earthquake
~ Roost
~ Ice Fang
~ Stealth Rock/Knock Off

Typical walling Gliscor set-up, counters what it needs to. Taunt for shutting down incoming potential counters, as well as making up to a degree for my total lack of phazing otherwise.

I personally think that Taunt on Gliscor isn't that great unless you're stat boosting. Stealth Rocks helps support your team quite well. Gliscor is also beastly after a few SD's, so Swords Dance could be used as his fourth move.

Mesprit @ Choice Scarf
Nature: Bold
Ability: Levitate
EV's: 240Spe, 188Hp, 80Sp.Atk
~ Psychic
~ Ice Beam
~ Thunderbolt
~ Rest

Original, yet something no one would expect. I like it and it fits your team well.

Scizor @ Choice Band
Nature: Adamant
Ability: Technician
EV's: 252Atk, 172Spe, 84Hp
~ U-Turn
~ Iron Head
~ Pursuit
~ Quick Attack

Finally, something that punishes Cresselia and Celebi. Priority is also a massive asset to any team. Considered a Specs Gengar here, just to give me a bit more special oomph on a predominantly physical team, but then I lose my Dragon resist. Considered Specs Lucario here, but then I can't touch Cress.

Not true. Specs Luke is actually quite useful against unsuspecting Cresselias with Dark Pulse, which should 2HKO. Since you didn't go the SD+Quick Attack route or Baton Passing, I would use a Bulky SD Luke. He used to be in the D/P Analyses on Smogon, but I can't find them . The general idea is to reach 224 speed to outspeed Gyarados, enough defense and HP to turn Adamant Garchomp Outrage into a 3HKO, and the rest in attack.

It's not that bad, keep in mind that I have not looked at the weaknesses yet, so there may be some glaringly obvious ones I may have missed.

~ Might consider SR on Gliscor, but Taunt is enormously useful in stall wars against the likes of Skarmory.

~ I'm not too sure about that Ursaring; he's too slow to attempt a proper sweep. ReSTalk still has enormous power; ReSTalk gives him the staying power he needs against the likes of Hippowdon, Gliscor, Drill Peck Skarmory and Blissey, who can all only manage a 3HKO.

~ You're probably right about Flamethrower < Ice Beam, I'll change that now. I'm trying leftovers, I haven't run into any Dugtrio yet so I'll probably do that too.

~ Can't really lose Scizor for Lucario, as I'm starting to get a massive Weavile weak I'm going to run a bulkier Scizor actually, just because Weavile can be problematic.
