When you cast Bellows Breath with Repeat on a target with Deflect, do you pay the Deflect cost once or multiple times?

Ruling: You only pay the Deflect cost once, even though Bellows Breath targets the same permanent multiple times (three times normally, six times with Repeat). Deflect's additional cost applies per spell or ability, not per individual target choice.

Nuances:

• Bellows Breath targets three times without Repeat and six times with Repeat
• Even though the same permanent is chosen as a target multiple times, it's still only one spell targeting that permanent
