Kingdra@Life Orb
Naughty/Sniper
~Dragon Dance
~Waterfall
~Outrage
~Hydro Pump/Draco Meteor
DDance Kingdra. Dragon Dance boosts Kingdra's already decent Attack and Speed Stats into something to be truly feared. Waterfall and Outrage are your dual STABs, getting near perfect coverage with them, being resisted by only Shedinja, iirc. The choice between Hydro Pump and Draco Meteor is yours, both have similar roles, but ahve different coverage, so choose accordingly.
Dragonite@Choice Band/Muscle Band
Jolly/Inner Focus
~Dragon Claw
~Superpower
~Waterfall
~Extremespeed.
This set uses all the advantages that Dragonite has over Salamence, Extremespeed and Superpower. Dragon Claw is your Primary STAB move, dealing tons to anything that take neutral damage from it. Superpower hits Steel types who may give you trouble, and Ice types, who Dragonite fears. Waterfall works wonders with Dragon Claw, as mentioned with Kingdra above. Extremespeed rounds this set of with a revenge killing move. Choice Band is prefered due to the extra damage output, but Muscle Band is an option if you dislike being locked into one move.
Gengar@Wise Glasses
Timid/Levitate
~Shadow Ball
~Focus Blast
~Thunderbolt
~Energy Ball.
The standard ingame Gengar. Shadow Ball is there for STAB, obviously. Focus Blast hits Dark types, and gets perfect neutral coverage alongside Shadow Ball. Thunderbolt and Energy Ball round this set off, giving great coverage.
Typhlosion@Choice Scarf
(Modest/Rash)/Blaze
~Eruption
~Flamethrower
~Focus Blast/Earthquake
~Hidden Power [Grass]/Thunder Pawnch
Color coded, so you should be able to understand which goes with which. Choice Scarf ensures that you always pull off the first turn Eruption, which does heaps to anything that doesn't resist it. Flamethrower is a reliable STAB move to fall back into, should your HP drop to the point where Flamethrower would do more damage. Focus Blast and Earthquake both do the same thing, that is, to hit Rock Types, who give Typhlosion trouble. Focus Blast can be used alongside Rash, but not Earthquake with Modest. Focus Blast is generally perfered due to the fact that it runs off Typhlosion's higher base Special Attack, and higher base power in general, although Earthquake has the advantage of better accuracy, at the cost of power. If you can breed for it, Hidden Power [Grass] is perfect, as it effectively hits all of Typhlosion's weaknesses, but Thunder Pawnch also works as a method to hit Water types.
Ampharos@Leftovers
Modest/Static
~Thunderbolt
~Thunder Wave
~Focus Blast
~Signal Beam
Thunder shouldn't be used unless supported by rain, as it's low Accuracy will play against you sooner or later. Thunderbolt is the prefered STAB move, as it has an impressive base 142.5 attack, factoring STAB. Thunder Wave allows you to cripple faster opponents, working well with Ampharos' natural bulk. Focus Blast is for coverage, which is always appreciated. Signal Beam is there to hit Grass Types, who otherwise resist this set.
Hope this helps.
