Mirrorwing Dragon

13/07/16

If a player casts an instant or sorcery spell that has multiple targets and Mirrorwing Dragon is chosen as the target in each instance, Mirrorwing Dragon’s ability will trigger. Each of the copies will similarly be targeting only one of the player’s other creatures.

If the spell that’s copied is modal (that is, it says “Choose one —” or the like), the copies will have the same mode. A different mode cannot be chosen.

The 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.

The copies are only created targeting creatures that the spell’s controller controls. Copies are not created for all creatures on the battlefield, and the affected creatures may be controlled by a different player than the controller of Mirrorwing Dragon. Notably, if you cast Murder targeting your opponent’s Mirrorwing Dragon, your creatures will each get a Murder, not your opponent’s.

The player who cast the original spell controls all the copies. That player chooses the order the copies are put onto the stack. The original spell will be on the stack beneath those copies and will resolve last.
