So which comes first?

Extraordinary Day
A roll of 11 or 12 on any attack roll is a critical hit. A roll of 2 or 3 on any attack roll is a critical miss.

Madness
Critical hits are critical misses instead, and vice versa. When a character uses Support, the target is healed of 1 fewer damage on a critical hit.


If ED is first:
ED goes into effect and sets the new die roll, and then Madness switches hits/misses.

but if Madness goes first
Madness switches the hit/miss, but then ED sets the new die roll.

or does the order even matter?

i see it as being that ED defines what a crit hit will be, ie what rolls will be a critical hit, whereas madness reverses the two, so ED before madness
(which would work in my favour...i tend to roll a lot of 3's)

i don't think the order matters. Madness swaps crit hits and misses. Extraordinary Day defines what they are. Either way 1+2 end up being crit hits and 11+12 end up being crit misses.

Those two cards getting played at the same time is about as likely as a meteor strike against a specific person.

How many time have you seen madness played? I mean really.

A lot at the current venue I attend, actually. One player in particular is just mad for Madness... ah, I kill myself

I run random BFCs at my shop, so I see madness a lot! I can't wait to see these two go off.

Loads of times, actually. When people still want to play a BFC but don't care... not to mention the wonderful world of random BFC tournaments. Have two played at the same time, this would come up.

Just because its rare doesn't mean it shouldn't be clarified.

I echo scehaono's observation. Madness swaps them and ED redefines them. Whether they're swapped and then redefined or redefined and then swapped yields the same result.

It doesn't matter how often we have seen Madness played, the question is still valid. When I was an envoy, statements like the ones above aggrevated me the most. "It will never come up"... Well, someone thought up the question, so there are times when the situation could come up, therefore the question needs an answer.

I plead the 5th.
