I play Necrons. My general tactic is to slow the enemy down as much as possible and pour firepower in, letting We'll Be Back take care of my few casualties. My Destroyers dart around picking on vehicles and trying to stay out of hand-to-hand, my Warriors shoot, and my Pariahs attack weakened units to make them flee, as Pariahs reduce Leadership to 7.
Best Moment: Veil of Darkness takes a squad of Pariahs right next to a full squad of Dark Reapers, who then fail their Leadership test due to shooting casualties and run straight into the Pariahs.
