Gengar and Hydreigon both really wish they had nasty plot...
My two favorite pokes are by far Gengar and Hydreigon, and I have yet to make a team based on them. I decided to try and build a team around them, and have had moderate success with it. I am receptive to any and all recommendations for my team except getting rid of Gengar or Hydreigon, since they are obviously the reason the team exists in the first place.
Deoxys-S @ Focus Sash
Timid
252 HP/4 Sp. ATK/252 SPD.
HP Fire
Stealth Rock
Spikes
Taunt
Typical Deoxys-S. Taunts or starts setting up. HP Fire is for Forretress and Ferrothorn. Obviously, doesn't like rapid spin, prankster, or Espeon. Entry hazards are a valuable part of my team, but if anybody can think of one that would work better with my other team members, I'm open to suggestions.
Hydreigon @ Choice Specs
Timid
4 HP/252 Sp. ATK/252 SPD.
Draco Meteor
Dragon Pulse
Flamethrower
Focus Blast
My main special sweeper. This thing hits so hard with choice specs, it's ludicrous. Draco Meteor is there for hitting as hard as possible in one shot, while Dragon Pulse is for more reliable STAB. Flamethrower is to hit every steel type that isn't Heatran, while Focus Blast is there specifically to take out Heatran. I realize that Life Orb/Expert Belt provides more versatility, but at the moment, I like the raw power of specs.
Gengar @ Leftovers
Timid
4 HP/252 Sp. ATK/252 SPD.
Substitute
Disable
Shadow Ball
Focus Blast
Subdisable to mess up pokes that can't handle it. Very effective against walls and attackers with only one coverage move (Conkeldurr, for instance). Shadow Ball and Focus Blast hit pretty hard, too. I've heard that Subsplit Gengar is pretty good, but it sounds very difficult to use.
Magnezone @ Air Balloon
Timid
36 HP/252 Sp. ATK/220 SPD.
Thunderbolt
Charge Beam
HP Ice
Toxic
Steel trapper and revenge killer. This is my best way for getting rid of skarmory and cloyster, among other things. Toxic is there to mess up walls and tanks who can't afford to be poisoned. Especially effective against gastrodons that think they can safely switch in on me. I use HP Ice to deal with dragons, but I'd also consider HP Fire if that's better overall.
Landorus @ Choice Scarf
Naive
252 ATK/4 Sp. ATK/252 SPD.
Earthquake
Stone Edge
U-Turn
HP Ice
Good revenge killer, scout, and annoyer. Excellent for disposing of gliscor and ruining dragons. Good partner for terrakion, despite shared weaknesses.
Terrakion @ Life Orb
Jolly
4 HP/252 ATK/252 SPD.
Swords Dance
Close Combat
Stone Edge
X-Scissor
This guy is a beast even before he's used Swords Dance. After he has, watch out! I swept an entire team (after hazards were down) with just this guy without even setting up an SD. I find him to be incredibly useful. X-Scissor is used to hit bulky psychics who might otherwise survive one of his STABs.
