Ninjask- [att + / sp.atk -] @ leftovers/liechi
EV: Speed, atk, leftovers in hp
-silver wind/aerial ace
-swords dance
-baton pass
-substitute (preferred to have hp to be a number that's one higher than a number divisible by 4 then)
Ninjask has natural agility so you really don't need it. Use substitute for the same effect as protect but gives you the chance to pass the sub if it lives. Use swords dance once if you can, and if you did get one without dying (consider yourself a bit lucky), go pass it off.
Shedinja- [atk + / def -] @ lum berry
EV: atk, speed
-shadowball
-toxic/HP Physical
-protect
-confuse ray/silver wind
Focus band works only 10% of the time so blah... use lum berry to protect you from confuse ray, toxic or will o wisp. All the other attacks are in there to kill.
Blaziken1- [speed or attack + / sp.atk -] @ white herb/lum berry
EV: Atk, speed mainly
-overheat
-brick break
-earthquake
-quick attack
Kills reversal/flail abuser with QA. Brick break and earthquake are just handy, and overheat+white herb combo for a major fire attack (which is very threatening even with no EV and a negative nature)
Blaziken2- [sp.atk or speed + / atk -] @ white herb/lum berry
EV: Sp.atk, speed, atk
-brick break
-overheat/flamethrower
-HP Grass
-quick attack
Slightly different but around the same
Alakazam- [speed + / atk -] @ lum berry/petaya
EV: Sp.atk, speed
-psychic
-elemental punch
-calm mind/elemental
-recover/elemental/sub
Meh... too good stats... throw on anything special, and it'll be good pretty much. You're focusing on OHKO with fast speed and high special attack, or setting up a bit to make that even better.
Corsola-
(no help available) I have no idea how to even use this thing... it's a Pokemon that's evne harder to use than Quaggy
Metagross- [atk + / something -] @ lum berry
EV: (with agility) speed at 198, atk, hp/def
-agility/explosion
-meteor mash
-earthquake
-psychic/explosion
^^; Rather simple... 198 should be your speed if you're using agility, because 396 is the magic number to kill Jolt/Aero/Cro
Read the advanced trainer's guide that's a sticky in this forum for more basic info about battling ^^; Have fun on NB!
