The VG Resource

Machamp with the ability No Guard and the move Dynamic Punch. Annoy the crap out of everyone with this.

jumpluff with leech seed sleep powder hidden power and substitute
i've buttdestroyed entire uber teams with this

Absol with:
Abilityuper Luck (cause this set revolves around critical hits)
Attackstone-Edge (powerful and critical hit chance is higher)
Night Slash (STAB and critical hit chance is higher)
Slash (critical hit chance is higher)
Psycho Cut (critical hit chance is higher)
Item: Scope Lens (critical hit chance is higher)
Nature: Adamant or Jolly, depends if you want it to be faster or hit harder
As for EVs I'd recommend maxing it's Attack and Speed
You could also use Honchkrow, but Absol is faster, stronger and has a better movepool
