DK_Hammer, I am asking you as one user to another. Please don't use that language here, cursing is totally unnecessary.
As far as dirty tricks at that point level? Since there's no Lord, the Scouting Vampire is pretty nasty, agreed. The 10 Wraiths is an absolute Nightmare for most armies to deal with, -especially- combined with the Helm.
I, personally, think at that low point of a game if you purely want to win and are not concerned about the sportsmanship of the game (AKA taking 'Cheese') then the Wraiths + the Helm are your best bet. You'd only have to keep them away from the three or so characters, and they'd absolutely devour everything else.
