in truth this belongs in the 'bad cheese' catagory, but I want to talk up the lost and damned as much as possible since we can still feild it at gt's.
first off, I'd like to say that the more powerfists attacks you get on the charge, the more guys you tend to kill.
that being said, three squads (two of 27 and one of 16) that have 11 powerfist attacks on the charge (and 9 standing) are pretty kick ass. add to that the fact that the little one moves, fleets, and then charges 12, and well, you've got a scary horde on your hands.
then we've got the deamon prince from hell. str 6, tough 6, 4+d6 attacks standing statured, and fast enough to keep up with the fleeting mutants, this kid has cause a whole lot of bed-wetting, and in a single game has killed 600 pts (4 whole squads) of space marines, by himself.
that being the basis of the army, I've now got about 700 points of toys
three groups of furies give me a little more manoverability, and a couple obliterators give me a lascannon or two for fun. Round things out with three armor 13 defilers, walking right up the middle so that you have to deal with em, and we've got ourselves a ball game.
this list phased kevins necrons in 3.5 turns. werd.
