Does Falling Star target on declaration, and is this the case for all spells or only ones that say 'do this x times'?

Ruling: Only spells that say "do this x times" (or "do one of the following") do not target on declaration. These spells create reflexive triggers upon resolution, and targets are declared when finalizing those reflexive triggers as the spell resolves, not when the spell is initially played.

Sequence:

• When playing the spell initially, you do not declare targets
• The spell resolves and creates reflexive triggers
• You declare targets as you finalize each reflexive trigger during resolution

Nuances:

• This applies to spells with "do this" or "do one of the following" language
• Falling Star is an example of this type of spell
• Other spells that don't have this language do target when the spell is played
