RMT - Suggestions are appreciated - Mixed Tiers

I've been messing around with this team on showdown in pretty much all the tiers. Surprisingly it was particularly strong in ubers, as most people have no idea what each Pokémon is capable of. Due to most of my usage of this team being in the ubers tier, I'll be mentioning ubers threats in particular.
Darmanitan@ Choice Scarf (Lead and Revenger)
Ability: Sheer Force
Nature: Adamant
-Flare Blitz
-Earthquake
-Superpower
-U-Turn
EVs: (252 Attack, 4 Sp.Defence, 252 Speed)

I find great success using Darmanitan as my scarfer in this team, being able to easily OHKO potential threats like mega Mewtwo Y and unscarfed genesect, whilst being able to put a large dent in to other threats such as Xerneas. I prefer using Darmanitan over a different scarfer such as staraptor and nidoking (which were alternatives I was considering) because I feel the STAB flare blitz is guaranteed to damage most opposing Pokémon to the point where noivern or scizor can take it out, as well as dealing with threats like opposing scizor, ferrothorn and forretress which would otherwise wall me.

Slurpuff@ Sitrus Berry (Set-up sweeper)
Ability: Unburden
Nature: Jolly
-Belly Drum
-Play Rough
-Wish
-Cotton Guard
EVs: (252 Attack, 68 HP, 192 Speed)

This little guy has surprisingly wreaked havoc in the ubers tier from my recent experience (once common walls have been dealt with). Considering the significant number of dragon types in the tier, Slurpuff often OHKOs 4 serious offensive threats in a row before eventually being taken down by priority or a miss with play rough. The last two moves are almost filler, but allow me to increase my physical defence, making it more likely that slurpuff survives any extremespeeds coming its way. With the amount of speed I run, after the unburden boost slurpuff can outspeed scarf kyogre. I run just enough speed to outspeed scarfchomp for its use in OU after an unburden boost.

Noivern@ Choice Specs (Fast specs)
Ability: Infiltrator
Nature: Timid
-Draco Meteor
-Boomburst
-Air Slash
-U-turn
EVs: (252 Sp.Attack, 4 Defence, 252 Speed)

Noivern is a fairly new addition to the team, and I'm not sure I'm using it to it's full potential. On paper, Noivern seems great for ubers, being able to outspeed every dragon type in the tier and OHKO it with Draco Meteor. However, it seems that in most situations the opponent simply switches in to a fairy type such as Xerneas or Fairy Arceus, giving them a free turn of set-up.

Scizor@ Life Orb (Set-up sweeper and Revenge Killer)
Ability: Technician
Nature: Adamant
-Bullet Punch
-X-Scissor (don't have access to bug bite)
-Swords Dance
-Roost
EVs: (252 HP, 4 Defence, 252 Attack)

I use Scizor often to put dents in to fairy types, Xerneas in particular. After receiving damage by my walls, Scizor can easily KO a Xerneas after a geomancy which would otherwise sweep this team.

Edit: I've now started using mega scizor. I feel the added bulk I receive and the fact I'm no longer loosing so much HP helps give more utility to this scizor.

Swampert@ Leftovers (Physical Wall)
Ability: Damp
Nature: Impish
-Earthquake
-Roar
-Toxic
-Stealth Rock
EVs: (248 HP, 252 Defence, 8 Attack)

I feel Swampert is perfect for use in ubers. Firstly, if I were predicting a Xerneas lead, leading with Swampert allows me to roar it out, wasting its power herb and making geomancy no longer viable. And from many physical threats, Swampert is able to eat up hits and get some crucial damage before my revenge killers clean up. With the lack of grass type moves in ubers, Swampert practically has no weakness and many accidently hit Swampert with an electric attack, forgetting it is part ground.

Goodra@ Assault Vest (Special Wall)
Ability: Sap Sipper
Nature: Careful
-Power Whip
-Dragon tail
-Earthquake
-Rock Slide
EVs: (248 HP, 108 Defence, 152 Sp.Defence)

Goodra can sponge up special hits with ease. I run a physical set as I feel it catches opponents off guard and utilises attack increases gained from predicting grass attacks from threats like shaymin. I use dragon tail to cause some chip damage whilst taking advantage of stealth rocks, causing problems for Ho-Oh and other threats weak to stealth rock. The defence investment is to reduce damage taken from a mega Mewtwo Y's Psystrike.
