In the second edition of A Study in Emerald, Fenians have a one-use benefit that allows you to have agents count as two Bomb points instead of one. They also have a Bomb point on them.
The rules for assassination say:
Each card that you play that has symbols on is worth Bomb points equal to the number of such symbols on the card.
Since you are playing the Fenians card to use their benefit at this time, does it also add its own Bomb point, or do cards played for Bomb points have to be played exclusively as such?
