Don't care about no rules, I just like having some pretty figures to paint (and of all the figures in Warhammer Fantasy, walking mummies are actually quite useful elsewhere too - add some 20th century adventurers and you've got countless pulp story lines right there). A King, a unit of Tomb Guard and a few big scary things and you're good to go. Beyond that, they're just nice in the display cabinet, and I don't think they'll be a disappointment to paint up.
