When I repeat Bellows Hearth, can I choose different units the second time?

Yes, when you pay the Repeat cost for Bellows Breath, you can choose different units for the second execution of the effect.

According to Rule 746.2.a: "Choices made for the additional execution do not have to be the same as the choices made for the initial execution."

How it works:

1. First Execution: You choose a location and deal 1 damage to up to three units there.
2. Second Execution: You may choose the same location or a completely different one. You then choose up to three units at that location to deal 1 damage to. These can be the same units as before (to deal a total of 2 damage to them) or entirely different units.

Key Details:

• Targeting: While a single instance of Bellows Breath cannot target the same unit more than once, the repeated instance is a separate set of choices, allowing you to hit the same unit a second time if you wish.
• Timing: Both instances of damage happen during the resolution of the same spell. Cleanup (checking if units die) only occurs after the entire spell—including the repeat—has finished resolving.
