If you want dragonite a special sweeper it's okay. He's good to in that way. I rather love to use it as a physical
But let's start with the ferrotorn (you will most of the time put him out as first one, depends on the opponents team though)
Possible attack set +IV/EV spread
1) - Stealth rock, toxic spikes, Protect and leech seed
-31/x/31/x-/31+/31 (Since it doesn't have any attack moves)
-252/x/x/x/80/176 (You can also do 252 on SpDeff and 4 on Deff, but I put 176 on speed because it can outspeed a forretress with 31/0 (IV/EV) in speed)
-Item: Something like rocky helmet or leftovers would be okay
-Iron barbs
2) -Gyro ball, Power whip, Stealth rocks and leech seeds/protect/toxic spikes
-31/31+/31/x/31/
0- (This zero is to maximize it's gyro ball)
-x/56/200/x/252/x
-Item: Leftovers will be the best I think
- Iron barbs
I use 2) myself
Then Gengar. I love this pokemon really really much
1) -Shadow ball, focus blast, thunderbolt/Sludge bomb/psychic/giga drain, (the same 4) (I would never use giga drain, but I think it could work)
-31/x-/31/31+/31/31
-4/x/x/252/x/252
Item: Choise specs/Black sludge
-Levitate
2) Hypnosis, Trick, Shadow ball, clear smog (This one's really to f*ck the other one)
Same thins as above, only certainly attach choise specs
Technique here: Use on the first one a trick, gengar get's a good item, the other one get's choise specs (the best is when you do it on a physical attacker, or a pokemon who most of the time does a boosting move when he comes in, like dragonite cloyster and scizor) then you can start playing around. When he switches out use hypnosis, or when you have to battle a boosted poke, just switch him in, use hypnosis and then clear smog (choise specs need to be gone already)
Dragonite (My favourite dragon pokemon
)
1)Give him leftovers or white herb
Draco meteor, hurricane, roost, surf/blizzard/ice beam
31/x/31/31/31/31
252/x-/x/252+/4/x (Bulky set)
4/x-/x/252+/x/252+ (Fast set, but he cannot outspeed a lot of pokemon except when you would attach choise specs, witth his basic 80 speed stat)
multiscale
2)(The physical set nr1) Give him leftovers
Extreme speed, dragon dance,roost, outrage
31/31/31/x/31/31
252/252+/x/x-/4/x (Bulky set => preferred)
4/252+/x/x-/x/252+ (Fast set)
Multiscale
Technique: With his multiscale ability dragonite becomes very powerfull, to my opinion it should become uber
. You just start with a dragon dance (speed + attack goes up) then when you have lost to much HP you useroost till your HP is okay, if this doesn't work, just do an attack. 1,5 times attack can do a lot of damage.
3) The above one but with attacks: Dragon dance, earthquake, outrage, extremespeed/roost
Starmie vaporeon and Scizor I don't use a lot, so maybe listen to the others.
I could give you more info when I had more time :-/
The +/- next to EV/IV is for the nature (which stats the nature should boost.)
