- 4 October 2004Adding a counter is optional. If you forget to add one during your upkeep, you cannot back up and add one later.
- 4 October 2004You can activate the ability (choosing no targets) even if there are no verse counters on it. It doesn’t do anything useful if you do this.
- 4 October 2004You count the number of counters, then divide up the prevention during the announcement of the ability. Each targeted creature receives the appropriate amount of damage prevention when the ability resolves.
