Turn to Dust targets a gear that is attached, what happens?

If you play Turn to Dust on a piece of gear that is currently attached to a unit, the following occurs:

1. Resolution: Turn to Dust resolves and grants the [Temporary] keyword to the attached gear.
2. Activation: Although the gear's printed rules text is inactive while it is attached (per Rule 135.4), the [Temporary] keyword granted by Turn to Dust remains active.
3. Trigger: Because the granted [Temporary] keyword is active, its effect will trigger during your next Beginning Phase.
4. Result: The gear will be killed (sent to the trash) at that time. Once the gear is killed, it detaches from your unit, and any bonuses or effects it was providing to that unit cease immediately.

This interpretation is supported by the 2026-04-29 Rules FAQ, which clarifies that while an attached gear's printed text is inactive, any granted rules text (like the [Temporary] keyword from Turn to Dust) remains active and functional.
