"Restrict holder from making a rescue attempt. Restrict opponent from attacking holder. May be used twice. "
Opponent attacks me. I block with King Rehoboam and make his Elhanan fight my Rhoda. I play The Meal in Emmaus to activate Burial Shroud.
It seems practical to assume it does nothing, since my opponent has already begun attacking me, and there's no way to undo that, especially since I'm not interrupting the attack itself. But at the same time, I am still in the process of being attacked. The attack is not done until battle resolution, correct?
There is no REG entry for attack.
