When fielded, name a character die. Draw a die from your opponent’s bag, if it is the named die, you may field it this turn and attack with it. If you do, put it into your opponent’s Used Pile at end of turn. Return any unnamed dice to your opponent’s bag.
Please clarify Catwoman: Nine Lives ability. May any character face be fielded? Would the player pay the fielding cost associated with the chosen face? I would assume that the Catwoman player may field any face they can afford to pay for.
Also, I assume that fielding and attacking are a package deal - i.e. you can't field then choose not to attack.
