No, you may not use a Night Raid card on a player after the MOM card is played. Asstated in the rulebook: Once you’ve played a MOM card, you cannot be targeted againthat turn.Think of it like this: Before a MOM card is played a Night Raid cannot be MOM’dbecause you are attacking the other player while they are asleep. After a MOM card is played it’s like Mom comes into the room and sticks around for the rest of that player’s turn. She would see any funny business that occurs.
