Ooh, Absol. Used it a couple of times, to great effect.
#1: Legend Killer
Adamant, 6 HP, 252 Atk, 252 Spd
Super Luck, Focus Sash.
Use Swords Dance, survive a hit with Focus Sash, kill with Sucker Punch. Works surprisingly well when facing a team of Legendary Pokemon, as quite a lot of powerhouses don't have high enough Def to survive. Kyogre, for example. Wrong tier, perhaps, but who cares. Something in the lower tier can crush those in higher.
#2: Fancy Blade
Jolly, 6 HP, 252 Atk, 252 Spd
Super Luck (Magic Bounce), Absolite.
Requires BW2. But pretty straight forward. Go Mega. Kill. And switch out frequently for a potential for some insane Magic Bounce micro, which works well with Superpower's stat lowering effect.
Trying to get back into the games, but not really finding a purpose.
