Team advice?

I've decided to put together a team that will get me a good few more victories than my other teams have. IV bred and EV trained. Before I go to the effort of raising them, I'd like some advice on them. This is what I currently have planned.

Scizor, Adamant, Technician @ Scizorite
Bullet Punch
Aerial Ace
Swords Dance
Bug Bite X-Scissor

Gardevoir, Timid, Trace @ Sitrus berry
Psychic
Moonblast
Shadow Ball
Calm Mind/Thunderbolt

Weavile, Adamant, Pressure @ Chople berry
Ice Punch
Night Slash
Brick Break
Swords Dance/Aerial Ace/Poison Jab

Kabutops, Adamant, Swift Swim @ Sitrus berry
Waterfall
Rock Slide
X-Scissor
Swords Dance/Other move

Rotom-Wash, Calm, Levitate @ Damp Rock (if using rain dance) @ Wide Lens (if not)
Thunder/Thunderbolt
Hydro Pump
Rain Dance/Thunder Wave
Shadow Ball

Talonflame, Jolly, Gale Wings @ Sitrus berry
Flare Blitz
Brave Bird
Roost
Swords Dance


How does this look? I'm hoping to use Rain dance to give my team better resistance to fire, due to the presence of Talonflame and Mega Blaziken around here. It would also do good for Thunder on Rotom and Kabutops' ability. I added Talonflame because hey, if you can't beat them, join them. Scizor is the lead, going out to tackle the first threat, unless it's a fire type, at which point I switch to either of the water types I have. I then set up with Swords Dance or Rain Dance, and then go from there. Weavile can use Poison Jab for the odd Sylveon, and I'd like to give him a berry that helps him resist fairies but I don't know if it exists yet. Gardevoir, Scizor, and Talonflame can tackle the fighting types. Both special attackers have Shadow Ball and Thunderbolt for good coverage, but the repetition of the move might not be good. Maybe Gardevoir can have Energy ball instead?

Is there anything you can suggest to change this team, such as moves or items?

 

None of the people I battle with use hazards, oddly. Rapid spin and defog probably won't do much good. I could put rapid spin on Kabutops anyway, since I haven't officially plotted a move there, but I'd prefer moves that I can get a lot of use and coverage out of. Obviously the big reason I have X-scissor on Kabutops is to guard against grass types without having to switch immediately, or at least get a good hit out before he gets energy balled. This actually might not be that much of an issue considering how many grass resistant hitters I have on the team, so I could probably scrap X-scissor. Would it be a good idea to put rain dance on him as well?

Talonflame I would like to keep Swords Dance. Gale wings ensures that she can heal with roost immediately, and also it would be good to make up for the lack of the adamant nature. However I'll only use it when I feel it's safe to do so, so I can go on a run from there.

Scizor I feel needs Aerial Ace. In addition to being a great technician move it'll also be a sure fire way to get out of scrapes with grass-poison types like Venusaur that would normally shrug off X-Scissor, as well as strong fighting types and all-round coverage for opponents that resist his stab attacks.

So far the changes look like this:
Energy ball on Gardevoir rather than thunderbolt
Remove X-scissor on Kabutops, possibly rain dance, possibly hone claws? (accuracy for rock slide)
Definitely poison jab on Weavile

EV spreads will mostly be focused on their strongest attacking stat and speed, however for Pokémon with possible boosting moves like Kabutops I'd like to spread the EVs around to defences as well. Because hone claws/swords dance and rain dance would make up for what he lacks, it would be a good idea to make him more defensive so I can switch to him and possibly take several hits. Does this sound like a good idea or am I gabbing on like a crazy person? Everyone here has top IVs in every stat I intend for them to use so I guess they'll be pretty defensive from the get go.

Thank you all for your input, I should say.

EDIT: I've decided that Kabutops should get Aqua Jet and Rain Dance on his set to go with his more powerful moves. The rain will do good things for the priority move as well as boost his strongest attack, so Swords Dance won't be needed. As long as rain is there, he should be safe, especially if he's going up against Blaziken or Talonflame. Rotom Wash will also get Rain Dance with Damp Rock, to give a fighting chance to everyone else on the team but Talonflame, who can do well with Brave Bird anyway. It will also power up Hydro Pump and make Thunder hit surefire. Rotom will also get Thunder Wave as an annoying first move. Paralyse, set up Rain, switch to anyone else or attack.

 

So my team got me a hard won victory against my primary opponent at college, so I consider it a success! But, she has decided to counter my team with a Gravity based team - and to keep a step ahead, I must do the same. I will be constructing a Gravity team to take care of hers. This is what I've got so far:

Rotom-Wash, Calm, Levitate @ (undecided item)
Thunder
Hydro Pump
Will-O-Wisp
Shadow Ball/Rain Dance/Thunder Wave/Volt Switch

This is the same Rotom from my set, only given Will-O-Wisp and without the focus on Rain. Or should I keep it? I need help with the last move slot. Due to Gravity's accuracy boost (or evasion drop, I'm not sure how it works) all of its moves will hit, which is wonderful to hear.

Bronzong, Quiet, Heatproof @ (undecided item)
Hypnosis
Dream Eater
Earthquake
Trick Room

This guy will turn the tables quickly. As my opponent uses Gravity to start the match, I use Trick Room, then use my unbeatable speed to use Hypnosis, which is sure to hit. Then, Dream Eater for recovery or Earthquake to ravage the enemy. If I faint with this one, I switch to Ferrothorn to utilise any remaining turns of the gravity. For IVs, I'll go for maxed out in everything but speed. If possible, I'll go for a low speed IV (which may be very hard since it's difficult to get 6 desired IVs).

Ferrothorn, Brave, Iron Barbs @ Rocky Helmet/Leftovers
Spikes
Power Whip
Gyro Ball
Gravity

Ferrothorn will be my gravity setter, should I need one, and with its accuracy boost, Power Whip will never miss. Have to be careful about the opposition's Espeon, who has Magic Bounce, as I can only set spikes when it isn't around. I can probably Power Whip it away, or use Gyro Ball even. Rocky Helmet is for chipping away at physical attackers, or Leftovers to keep him in the game longer. For the IV set, I also want a very low speed IV, and I might be able to get it since I won't also be breeding for sp. attack. That way, I can get 5 desired IVs.

Tentacruel, (attack reducing nature), (any ability seems good) @ Black Sludge
Blizzard
Hydro Pump
Toxic Spikes
Rapid Spin

I need a rapid spinner and also one to take away toxic spikes. Tentacruel! With Gravity in effect, I can blow the opposition's ground types away with both massive damage dealing moves with little to worry about. Rapid spin will take away the spikes that will obviously centre in a gravity based team, and Toxic spikes will be a great help to me. For IVs, I'll give it a basic 5 IV set, forgoing attack. It's not like Rapid spin will to any good.

Question: is Tentacruel or Jellicent better in this role? Their stats are more or less the same, and they both get Blizzard, Hydro Pump and Rapid Spin. Jellicent doesn't take as much damage form Earthquakes as Tentacruel does and can block rapid spins, but Tentacruel gets Toxic Spikes and the ability to remove them. Which one should I use?

So this is my theoretical team so far. Four members isn't bad at this point, but I need more suggestions, preferably some solid ground types that are good in gravity. Considering Gigalith and Torterra. Also, if anything else catches your eye and you think you have any suggestions, please let me know. The areas in brackets particularly need suggestions.
