Netrep Q&As:
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 active 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. Curtis Schultz, 01/25/2004
