It didn't come with any blank ones but I can think of some fun new rules. Off the top of my head I'd make a Blind Keepers new rule, where everybody has their keepers face-down so nobody else knows what they are.
No blanks? NO BLANKS?? What a rip! Jeez those people got all sorts of twisted in their limited success!
Also: Is there no more "Government Cover-Up" card? That basically said all Keepers must be hidden (face-down) as long as the rule was in effect.
Not there any more? Damn. I think I'll stick to whatever version I've got, thanks.
Apparently there's some new fun stuff in there like the ever-popular X=X+1 (although I'd have called it X++).
