Sableye with:
- Thunder Punch
- Shadow ball
- Water pulse
- Dig
- Ability: Keen eye (For no accuracy loss(Though the opposite pokemon's evasiveness does still affect this ability, Sableye will more than likely strike before lack of ability to hit.)
- Item: Wide lens (For increased accuracy, making evasiveness less of a problem.)
If you can beat that without saying "Arceus", (Which is not even a legit answer since it even isn't that good, I should know, it got 3 shotted by everything in the Elite four in Sinnoh... Don't ask how.) you deserve a medal.
