Does Mirror Image make a 0-Might Reflection if the copied unit dies in response?
If I Mirror Image a unit and the opponent kills that unit in response, do I still create a Reflection, and does it have 0 Might or copy the unit?

Choose a unit. Play a ready Reflection unit token to your base. It becomes a copy of that unit. Give it [Temporary]. (Kill it at the start of its controller's Beginning Phase, before scoring.)

My opponent plays Mirror Image and chooses a unit for it to copy. I react by playing Retreat on that chosen unit. Does Mirror Image's reflexive trigger resolve or fail because the unit it referenced is gone?
Opponent Mirror Images a Rift Herald; I Star-Crossed the Herald in response. Does Mirror Image still copy the unit's traits?
Does a Mirror Image Elder Dragon copy get passive effects like preventing combat damage kills?
I have two Zilean, Time Mage on a battlefield and cast Mirror Image on a unit. Do I create two extra Reflections for three total, and are Zilean's Reflections ready too? Do multiple Zileans each copy Mirror Image's Reflection tokens?
