Prevent the next 3 damage that would be dealt to any target this turn by a source of your choice. You gain 3 life.
You gain 3 life as Healing Grace resolves, even if thereâ€™s no damage to prevent.
You choose only one source, even if that source wonâ€™t deal 3 damage.
Healing Grace only targets the creature, planeswalker, or player that will receive the damage prevention â€œshield.â€ The source isnâ€™t targeted.
