Heroism
From Fallen Empires set
Heroism
Enchantment
Sacrifice a white creature: For each attacking red creature, prevent all combat damage that would be dealt by that creature this turn unless its controller pays .
Rulings
- The cost to avoid the penalty must be paid when the ability resolves. You can’t wait until later to do so.
- Paying the Heroism cost to allow a creature to deal damage does not prevent other effects from preventing it from dealing damage. Paying the cost only prevents the Heroism effect.
