Darth Maul, Phantom Menace

Menace, first strike

{r}, Darth Maul, Phantom Menace gains haste until end of turn.
{1}{b}, {t} Destroy target creature

Whenever Darth Maul, Phantom Menace becomes tapped, it deals one damage to each opponent.

He had all the lightsaber fighting capabilities and the moves of the Jedi, only faster and more aggressive. My only conclusion... is that it was a Sith lord.
