Here's two sets I use sometimes;
Gallade@Wide lens/Life orb
Jolly
Steadfast
252 Att/236 Spe/20 Hp
Close combat
Ice punch/Stone edge
Swords dance/Thunderpunch/Leaf blade
Hypnosis
SD gallade set designed to abuse Steadfast, Makes a great lead to get the drop on ambipom and other fake out-ers, Hypnosis is there to cripple gallades counters, most of which aren't used as leads so a free hypnosis is always nice, since this gallade is meant to be used as a lead, Ice punch/stone edge is better than night slash in order to hit Gyarados/salamence/yanmega (If stone edge), Or Salamence/garchomp/dragonite/yanmega (If ice punch).
Swords dance is there to compensate for the Attack loss from adamant to jolly, But if you want, Leaf blade is there to hit rhyperior and swampert while thunderpunch is used to boltbeam punch or hit Toxicroaks if you opt for stone edge over ice punch.
The speed EV's allow it to hit 280 speed, outspeeding neutral base 90's, most notably lucario who will usually crunch you, thinking you're slower.
And then there's;
Floatzel@Life orb/Mystic water
Mild
Swift swim
252 SpA/252 Att/6 Hp
Rain dance
Waterfall
Hydro pump/HP electric/HP grass
Ice beam
This is a favorite of mine, Stole the Kingdra set and put it on floatzel, since floatzel is faster than Kingdra without a single speed EV, you are allowed to pump more EV's into Attack, 309 Att/295 SpA/532 speed after a rain dance is pretty nice, Hydro pump OHKO's hippowdon, but HP electric might be better to hit the bulky waters that usually switch into floatzel. Waterfall 2hko's blissey, ice beam hits grassers, fliers and dragons.
Probably onto nothing here, but these sets have worked well for me.
