If an undead team should manage to kill a troll they would be allowed to try to resurrect it with not 1 but 2 raise dead's thus leaving them with no raise dead for the next match.
The rolls would be made so that the undead's would have to make 2 successfull raise dead rolls before getting an undead troll onto their roster.
And if they failed either they still wouldn't have a raise dead for the next match.
Furthermore, the troll would suffer a -1 to ALL stats.
Fair? Unfair? Totally unfair? Tell me what you think!
I just had to post this as I found a great looking miniature which would suite this role perfectly!

Gee wiz, my first topic!
