Can Calamity Janet play a Punch as Missed?
No she can not play a punch as a miss. BANG! are specific cards and those are the only one she can use as a miss. There are other cards that can be used to damage players but they are not considered a BANG!. One of the key parts of a BANG! is you can only play one of them a turn unless you got a card that says otherwise and a punch or other damage card can be played as many times as you want.
