Lady J is very tough to play against, she kills most things. Come to think of it I dont think I have ever beaten her, so dont listen too much to me
Necropunks are very nice, tough and cheap and very mobile. Maybe a few dogs for bits.
Crooked men, hell yeah. blast markers and the possibility of paralising.
And punk zombies, even if they die they get that final slap in.
Just remember where your VPs are, you may be able to win the game without even engaging the enemy.
