Destroy target enchantment. You gain 2 life.
No longer the village pariah. No longer taunted and shamed. Sigrun was finally free.
Illus. Sam Wolfe Connelly

5/1/2012: If the enchantment is an illegal target when Cursebreak tries to resolve, it'll be countered and none of its effects will happen. You won't gain 2 life.
