When Falling Star creates multiple reflexive triggers, are all targets chosen simultaneously, and can players react between each trigger resolving?

Ruling: All targets for Falling Star's reflexive triggers are chosen one at a time (with deflect checks happening during targeting), but no players can react during the targeting phase because pending items prevent reactions. Players can react after all triggers are finalized and before each trigger resolves.

Sequence:

• Play Falling Star (players can react here)
• Falling Star resolves, creating 2 reflexive triggers
• Choose target for reflexive trigger #1 (deflect check if applicable)
• Choose target for reflexive trigger #2 (deflect check if applicable)
• Players can react here (all triggers now on chain, no longer pending)
• Reflexive trigger #2 resolves dealing 3 damage
• Players can react here
• Reflexive trigger #1 resolves dealing 3 damage

Nuances:

• Triggers technically finalize one by one, but no one can react while there are pending items
• Once triggers are on the chain (no longer pending), players get priority windows before each trigger resolves
• The chain doesn't fully resolve at once - after each item resolves there is another window of priority
• Deflect can cause individual triggers to fail to finalize during the targeting step if the cost isn't paid
