i believe that giving absol sword dance and sucker punch is good... so u should have...
super power
sucker punch
sword dance
psycho cut
and give it scope lens or life orb... xD
super punch covers the low speed of absol
u just have to survive one turn with sword dance.. then the real pwnage begins...
u have to predict wat the enemy will do though cause i believe that sucker punch has only 5 pp.
or instead of psycho cut, u can give baton pass (if it can learn it)
night slash is not needed because it sucker punch covers the dark type, so instead get psyhocut to reduce the amount of resistance..
