one space left for team!!!

[absolute_carnage]

i have one space left for my super duper battling team. currently i have:

steelix @ ???
252 atk, 252 def, 6 hp
impish

stone edge
EQ
swagger
psych up

ninetales @ white herb
252 sp atk, 252 spd, 6 sp def
modest

sunny day
overheat
confuse ray
???

umbreon @ lum berry
252 def, 252 sp def, 6 hp
relaxed/sassy/calm/bold/impish??

confuse ray
curse
baton pass
wish

ninjask @ focus sash
252 def, 252 sp def, 6 hp
bold

protect
endure
double team
baton pass

swellow @ toxic orb
252 atk, 252 spd, 6 hp
adamant

facade
aerial ace
endeavor
u-turn

firstly i use umbreon, max out the cursing, baton pass out to ninjask, who gets all the speed back, along with a double team just in case, baton pass out to swellow with a 315 base power facade. :)

i need one more to use. im thinking high in sp atk or sp def.
ideas so far:
ampharos <-- i like that one
mismagius
venusaur
meganium
togekiss


any suggestion for my final pokemon or ratings for my team so far?

gr8ly appreciated
