One ruling from Wizards of the Coast
- 25 January 2019An instant or sorcery spell must actually deal damage to a creature for it to be destroyed. Simply targeting a creature isn’t enough. If the spell instructs another object to deal damage, the spell doesn’t deal any damage itself and its instance of deathtouch doesn’t apply. Dealing 0 damage isn’t dealing damage.
