I've found a lot of success with my Knights of Blood (BA 'dex) army by presenting multiple close combat threats, all of them fast moving (jump or in a fast transport), with varied capabilities. Assault marines are good bullies and they score, and with a priest they're hard to remove. Death company are terrifying. Hammernatorts are, well, hammernators. My opponent can't shoot them all down, and I end up getting stuck in on his side of the board. While I usually lose my one scoring unit, I almost always take out my opponent's scoring units and win on a combination of First Blood, Linebreaker, and/or Slay the Warlord.
