Okay, i know this probably looks like i am ignoring you all, but i have taken everything in, particularly on Gengar, but this is gonna be the new team, please tell me if i have got it wrong with Empoleon and Torterra:
Gengar @ Life Orb
Timid
Levitate
252spd,252sp.atk,4hp
Shadow Ball
Thunderbolt
Focus Blast
Energy Ball
This should do better at leading than Dragonite. Special Sweeper
Empoleon @ Leftovers
Timid
240sp.atk,240sp.def,46hp (tell me if i've got the hp wrong)
Hydro Pump
Ice Beam
Flash Cannon
Agility/Toxic (not sure wether to weaken or try to outpace enemys, although the latter is probably impossible)
Bulky Special.
Dragonite @ Leftovers
Jolly
Inner Focus
252atk,252spd,4hp
Dragon Claw
Dragon Dance
Fire Punch
Earthquake
Physical sweeper as usual.
Torterra @ Lefties
Jolly
240hp,240def,46atk
Light Screen/EQ (prob. no EQ coz. nite's got it.)
Wood Hammer
Crunch/Stealth Rock
Protect/Stealth Rock
New physical wall, as you can see, i love all the starters from Diamond except the one i chose, and even Swampert isn't indespensible.
Cresselia @ Leftovers
Timid
240hp,240sp.def,46sp.atk
Psychic
Thunder Wave
Rest
Sleep Talk
Same old special wall...nowt rong wit it as far as eye can sea.
Lucario @ Leftovers
Naive
Inner Focus/Steadfast (got 2 with same nature and moveset)
200atk,200spd,108sp.atk
Aura Sphere
Extremespeed
Shadow Claw
Iron Tail
Mixluke of my own creation (well, more physical luke with STAB Aura Sphere)
Swampert may not be indespensable, but this guy is.
As should be obvious by now, my style is not very tactical, the closest i get to that is Stealth Rcok on Tortankterra and T-Wave on Cresspecialia. I hope you will apreciate this when rating.
I'm glad you took my advice, but it seems that you still have some problems.
Mamoswine weak, Weavile weak, lack of physical walling.
Okay, ditch Torterra. Put a physical wall over it such as Skarmory.
Life Orb Gengar should pack Hypnosis. If you don't want Hypnosis, go put Choice Specs on it.
Cresselia cannot wall effectively with Timid. Run the CM set if you can't change the nature. I would recommend something else > Thunder Wave since your team isn't reliant on paralysis.
Outrage > Dragon Claw since that is the only advantage Dragonite has over Salamence. If you want a set like this, run DDSalamence.
Sorry to tell you this, but you should try to use the standard and become acquainted with the metagame before making your own sets. Lucario should only be mixed if you have a Blissey problem. Either go SDLuke:
Lucario @ Life Orb
Adamant, 252 Attack, 252 Speed, 4 HP
Close Combat
Extremespeed
Swords Dance
Crunch/Bullet Punch/Stone Edge
or SpecsLuke
Lucario @ Choice Specs
Timid/Modest, 252 SpA, 252 Speed, 4 HP
Aura Sphere
Vacuum Wave
Dark Pulse/Shadow Ball
HP Ice/Dragon Pulse
I would put Bronzong > Empoleon and run Gliscor > Torterra. Bronzong takes care of Weavile and Mamoswine effectively and is effective as a lead.
Bronzong @ Leftovers
Relaxed/Sassy
252 HP/152 Atk/8 Def/96 SpD (Relaxed)
252 HP/152 Atk/8 SpD/96 Def (Sassy)
Gyro Ball
Hypnosis
Stealth Rock
Earthquake/Reflect/Light Screen
Gliscor @ Leftovers
Impish
252 HP/252 Def/4 Speed
Earthquake
Roost
Taunt
Ice Fang/Stone Edge/Aerial Ace
Overall a decent second attempt, but you should try the standards more before attempting to be creative.
