Mirror Image

Q: If I have one Zilean and play Mirror Image on a unit, how many Reflections appear? And what are they copies of?

Two Reflections; both become the targeted unit.

Card text now reads as:

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