Let's suppose I control Walder Frey, somehow give him an icon, attack with him and either keep him standing (or stand him before defenders are declared). Then the opponent I'm attacking defends with higher STR. What happens when Walder's passive resolves (I assume he kneels regardless):
- He stays an attacker and doesn't become a defender
- He becomes a defender and ceases to be an attacker
- He stays an attacker and becomes a defender
- The game breaks
