When multiple units die simultaneously (e.g., from Singularity), can you choose the order they die in so that Wraith of Echoes triggers from other units dying first?

Ruling: No, you cannot choose the order. When multiple units die simultaneously from the same effect, they all die in the same instance, so Wraith of Echoes cannot trigger from them.

Nuances:

• Zhonyas works differently because one replacement effect is replacing multiple separate death events, allowing you to choose which unit to revive
• Wraith of Echoes requires units to die sequentially for it to trigger from other deaths, not simultaneously
