Rulings
- While Final Attack Orders is applying, if you attack a face-down Defense Position monster, the monster is changed to Attack Position, then damage calculation is applied with the monster in Attack Position.
- While Final Attack Orders is applying, you can change monsters like Guardian Sphinx to face-down Defense Position, and while they are face-down, Final Attack Orders has no effect on them.
- While Final Attack Orders is applying, you can change the Battle Positions of monsters with Curse of Fiend or Little-Winguard, but the Battle Positions are immediately changed back to Attack Position by Final Attack Orders.
- While Final Attack Orders is applying, effects of Goblin Attack Force, Giant Orc, and Dark Zebra are resolved, but they are immediately changed back to Attack Position.
- While Final Attack Orders and Light of Intervention are applying, you can Special Summon a monster in face-up Defense Position, but it is immediately changed to Attack Position.
- The effect of Final Attack Orders cannot be chained to.
- Q: Opponent attacks "Crass Clown" while it is face-down on the field with a monster that has an ATK of 1400 or higher and "Final Attack Orders" is applying on the field. After flipping "Crass Clown" face-up, does it turn into Attack Position triggering its effect before being destroyed by the attack? A: Yes it would get its effect, but the effect will activate during the Resolve Monster Effects portion of the Damage Step, which is after damage calculation.
- Q: Can the position of "Crass Clown" be manually changed to Defense Position while "Final Attack Orders" is applying on the field, changing back to Attack Position by the effect of "Final Attack Orders", and thus activating the effect of "Crass Clown"? A: You cannot perform a manual change of position if the face-up monster is in Attack Position. You can still use card effects to change the face-up monster's position.
- Q: Are Face Down Monsters that are attacked while "Final Attack Orders" is applying forced into Attack position? A: Any face-up monster or monster turned face-up by an attack or a card effect will have its battle position changed to attack position due to "Final Attack Order's" effect. This includes a monster flipped face-up during the Damage Step. So while a monster like "Goblin Attack Force", "Giant Orc", and "Spear Dragon" have effects that switch them to Defense Position after having attacked, the "Final Attack Orders" will then switch them to attack position after their effect resolves.
