A Feint Plan

A player cannot attack face-down monsters during this turn.

• If A Feint Plan is activated and you control only face-down monsters, your opponent cannot attack any of your monsters and they cannot attack your Life Points directly either.
• If you activate A Feint Plan after your opponent declares an attack against one of your face-down monsters, that attack resolves as normal, but they cannot attack other face-down monsters for the remainder of the turn. (This is because A Feint Plan prevents declaring an attack against a face-down monster, and the attack has already been declared by the time A Feint Plan resolves during the Battle Step.)
