8 rulings from Wizards of the Coast
- 27 April 2018If the spell that's copied has an X whose value was determined as it was cast (like Jaya's Immolating Inferno does), the copy will have the same value of X.
- 27 April 2018Naru's triggered ability can copy any instant or sorcery spell, not just one with targets.
- 27 April 2018If the spell that's copied is modal (that is, it says "Choose one —" or the like), the copy will have the same mode. A different mode can't be chosen.
- 27 April 2018If the spell has damage divided as it was cast (like Fight with Fire does when kicked), the division can't be changed (although the targets receiving that damage still can).
- 27 April 2018The copy will have the same targets as the spell it's copying unless you choose new ones. You may change any number of the targets, including all of them or none of them. If, for one of the targets, you can't choose a new legal target, then it remains unchanged (even if the current target is illegal).
- 27 April 2018The controller of a copy can't choose to pay any alternative or additional costs for the copy. However, effects based on any alternative or additional costs that were paid for the original spell are copied as though those same costs were paid for the copy.
- 27 April 2018Because damage remains marked on a creature until it's removed as the turn ends, nonlethal damage dealt to a Wizard you control may become lethal if Naru leaves the battlefield during that turn.
- 27 April 2018The copy is created on the stack, so it's not "cast." Abilities that trigger when a player casts a spell won't trigger.
