If Falling Star kills a unit and Zhonya's Hourglass activates to save it, can Falling Star target that unit again in base to kill it a second time?

Ruling: Yes, if you announce both Falling Star targets as the same unit (Poro) when the spell resolves, the first trigger will kill it (replaced by Zhonya's), then the second trigger can kill it again in base, assuming it has 3 or less might.

Sequence:

• Falling Star resolves and you must announce both targets immediately
• Both reflexive triggers go on the chain
• First trigger resolves, killing the Poro (Zhonya's replacement effect activates, sending it exhausted to base)
• Second trigger resolves, killing the Poro in base (if it has 3 or less might)

Nuances:

• You must declare both targets when the original spell resolves, before either trigger resolves
• Both targets can be the same unit
• The unit must have 3 or less might for this to work
