So when an enemy attacks, you declare a defender, and he gets a shadow card that says "Attacking enemy attacks again after this attack. (deal it a new shadow card)", does he
1. Attack the same defender again undefended since you exhausted the defending character for the first attack
2. Attack the same defender again, but the defender counts his defense because he did not exhaust from the first attack yet.
3. Attack any other available character that you have under your control. The defender from the first attack is now exhausted.
Thanks
