Well, an update about Lansat Kingdra: It doesn't work. Lansat Berry and Focus Energy do not stack together for super crits...which really sucks.
Still, I came up with THIS devilish set that works like a set from another Pokemon we all know...
Lucario@Life Orb *ChainLuke*
Lonely
128atk/162sp.atk/220spd
Swords Dance
Close Combat
HP Ice
Psychic
Attract out the main fighting resist (Gliscor or Weezing) with Swords Dance or Close Combat, and then drop it with HP Ice or Psychic, both of which OHKO respectively (Weezing is with SR damage or a hit from CC, but has a chance without SR to live.) After this, feel free to scrap apart some other threats with Close Combat.
The EVs give Close Combat a punch after SD, and 220 speed hits 271, faster than the common 270s. You could opt for a little more speed and subtract from the attack if you'd like, but not preferable. I know most of Lucario's moves now give him an absurdly poor coverage, giving Cresselia the free liberty of switching in and forcing Lucario out, as well as things like Swampert surviving an SD Close Combat and no priority move to keep Weavile, Froslass, and Gengar away. (Bullet Punch for the latter 2)
So anyway...there ya go. Have fun surprising things with it.
