One ruling from Wizards of the Coast
- 4 October 2004The way the card works is that the target player chooses which creatures will attack on their next turn. Creatures which are chosen to attack, but do not attack, are destroyed at the end of that turn. Creatures which are not chosen to be attackers are not affected in any way other than being unable to attack.
