4 rulings from Wizards of the Coast
- 5 October 2018If the target creature is a legal target but can't be destroyed, most likely because it has indestructible, you still gain life.
- 5 October 2018You must sacrifice exactly one creature to cast this spell; you can't cast it without sacrificing a creature, and you can't sacrifice additional creatures.
- 5 October 2018The amount of life gained is equal to the sacrificed creature's toughness as it last existed on the battlefield.
- 5 October 2018If the target creature is an illegal target by the time Severed Strands tries to resolve, the spell doesn't resolve. You don't gain life.
