Surge of Righteousness

Oracle Text

Destroy target black or red creature that's attacking or blocking. You gain 2 life.

Card Rulings

2/25/2015 If Surge of Righteousness resolves but the creature isn’t destroyed (perhaps because it regenerated or it has indestructible), you’ll still gain 2 life.
2/25/2015 However, if the creature becomes an illegal target before Surge of Righteousness resolves, it won’t resolve and none of its effects will happen. You won’t gain life.
