La criatura objetivo obtiene +2/+2 hasta el final del turno. Ganas 1 vida por cada criatura atacante que controlas.
If the target creature becomes an illegal target for Take Heart, the spell doesn’t resolve. You don’t gain life.
You can cast Take Heart even if you control no attacking creatures, perhaps because it’s not even your turn. The target creature gets +2/+2 even though you don’t gain life.
