Alright, I got a cold :( so I now have time and then some to finally rate this. I started it a couple times but everytime I did I ended up deleting it because I didn't think it was sufficent. Now let's get cracking.
Tyranitar - CB T-tar looks like he could realy benefit the team, so that is exactly what I am going to have you do.
Tyranitar @ Choice Band
Trait: Sand Stream
EVs: 180 HP / 252 Atk / 76 Spd
Adamant nature (+Atk, -SAtk)
- Stone Edge
- Crunch
- Pursuit
- Superpower
Stone Edge is STAB and hits like a freight train, severely maiming anything that is not KO'd. Crunch is secondary STAB and hits relatively hard, while Pursuit works wonders for trapping frail Ghost and Psychic types that would rather avoid eating a Stone Edge, as well as anytihng else you think is going to switch out. Superpower takes down Steels and what not and is perfect on CB Tar, what with his hit and run nature.
Having Gliscor and Ferro is somewhat repetetive, so one of them is gonna have to go, and the one that gets the job as your physical wall is Skarmory.
Skarmory - Skarmory helps the team by not being weak to fighting and Ice, as well as being able to phaze and set hazards. Skarmory's fire and electric weaknesses are less than accomodating but I don't think it will be too much of a problem.
Skarmory @ Leftovers
*Trait: Sturdy
EVs: 252 HP / 252 Def / 4 SDef
Impish Nature (+Def, -SAtk)
- Spikes
- Stealth Rock
- Whirlwind
- Roost
It may look like Taunt bait but Taunt is rare in OU nowadays and I have used this set with success more often than not. Spikes and SR are extremely useful, and Whirlwind is amazing for phazing (aphazing, if you would), and Roost is for recovery.
Scizor - I am not sure how well that set works as I have never tried it, but should you get the feeling you need to change to something more offensive you can always consider standard SD Scizor.
Scizor @ Life Orb
Trait: Technician
EVs: 252 HP / 252 Atk / 4 SDef
Adamant Nature (+Atk, -SAtk)
- Swords Dance
- Bug Bite
- Bullet Punch
- Superpower
Swords Dance gets you up to super-dangerous level of attack, Bug Bite is secondary STAB, Bulet Punch is main STAB, and Superpower hits Steel types.
Landorus - You seem to need more special attackers, and special Landorus is an absolute powerhouse. He can lure in physical walls and dispatch them with his Sheer Force + LO boosted special moves.
Landorus @ Life Orb
*Trait: Sheer Force
EVs: 4 HP / 252 SAtk / 252 Spd
Modest Nature (+SAtk, -Atk)
- Rock Polish
- Earth Power
- Focus Blast
- Hidden Power [Ice]
Rock Polish boosts your speed to very sweepy levels and Sheer Force + LO makes it so you are hitting as if you had Choice Specs (excluding HP Ice)). Earth Power is STAB and hits insnely hard, Focus Miss is coverage and also is boosted by SF, and HP is yet more coverage.
Now that Ferrothorn is gone I am going to suggest you run Kingdra, as Kingdra has a great 4x resistance to Fire and Water, as well as the ability to counter rain teams with Swift Swim and his relative bulk.
Kingdra @ Chesto Berry
*Trait: Swift Swim
EVs: 152 HP / 128 Atk / 228 Spd
Adamant Nature (+Atk, -SAtk)
- Dragon Dance
- Rest
- Outrage
- Waterfall
Dragon Dance lets you boost your primary sweeping stats while your EVs sacrifice some offencive capabilities for bulk, allowing you to set up more. The main idea is you set up as much as possible, then Rest to heal yourself of status and recover lost HP. You are then free to Waterfall and Outrage to your heart's content ^-^
I like the presence of Magnezone here but his Steel typing is hindering the team by adding another Fire and Fighitng weakness. I suggest Jolteon.
Jolteon - Choice Specs Jolteon is a devastating revenge killer and late-game sweeper. I have used it a lot and it always pleases, and Volt Absorb really supports Skarmory.
Jolteon @ Choice Specs
*Trait: Volt Absorb
EVs: 4 HP / 252 SAtk / 252 Spd
Modest Nature (+SAtk, -Atk)
- Thunderbolt
- Hidden Power [Ice]
- Signal Beam
- Volt Switch
Thunerbolt is STAB and hits VERY hard, HP is coverage against gorund types and Thundurus-T, Signal Beam takes down Psychic types mainly and will most likely never get used, and Volt Switch you will probably use the most, as it hits hard and is great for revenging and scouting.
