When using Falling Star on a unit with Deflect, do you have to recycle 2 runes (one for each instance of 3 damage) or only 1 rune?

Ruling: You must recycle 2 runes when targeting a Deflect unit with Falling Star because it creates 2 separate reflexive triggers, and you pay the additional cost for each trigger that targets a unit with Deflect.

Sequence:

• Play Falling Star
• Players can react
• Falling Star resolves, putting 2 reflexive triggers on the chain
• Pick targets for the 2 reflexive triggers
• Pay additional cost for each trigger that targets a unit with Deflect
• Players can react
• First trigger resolves dealing 3 damage
• Players can react
• Second trigger resolves dealing 3 damage

Nuances:

• The "do this ... :" wording on Falling Star indicates it creates reflexive triggers
• Players can react between each trigger resolution
