One of the things that really drew me to Malifaux, besides my friends, was the card mechanic. The Red Joker and Black Joker, when in the deck, add a very small factor of uncertainty. This is can be a lot of fun. I groan when my 3+T attack yields no damage, and roar when my negative flip turns out to be an utter success.
However, it's easy to see why the Red Joker on a negative flip is not always the same as a Black Joker on a positive flip, as the outcomes depend entirely on the situation. Furthermore, this is the real question behind this discussion, namely "Does the Red Joker on a negative flip work to undermine the purpose of the Negative Twist"? I haven't played enough to have a definitive answer, but this discussion seems like it deserves a more critical eye than just "no" or "yes" answers. Personally, I feel really cheated when the Jokers are able to circumnavigate my defenses in a way that models who do not rely on twist protection do not suffer from. That's feeling though, and not evidence of whether or not the system works. Where are this board's card math experts?
