When Falling Star targets a Stalwart Poro twice and the first trigger activates Zhonya's Hourglass (recalling and healing the Poro), does the second trigger still deal damage to the Poro and potentially activate a second Zhonya's?

Ruling: Yes, the Poro remains a valid target for the second Falling Star trigger. Since the Poro never died (it was recalled and healed by Zhonya's), it's the same object and can be damaged by the second trigger, potentially activating the second Zhonya's.

Sequence:

• First Falling Star trigger damages the Poro
• Poro would die, activating first Zhonya's Hourglass
• Poro is recalled and healed
• Second Falling Star trigger still resolves and damages the Poro (it never left the board as an invalid target)
• Second Zhonya's can activate if the Poro would die again

Nuances:

• Falling Star doesn't have a restriction requiring the unit to be in a specific location for the damage to resolve
• The Poro remains the same game object throughout this sequence since it never died
