If Spinning Axe has its temporary trigger on the stack during beginning phase, and you cast Angle Shot to attach it to a unit before the trigger resolves, does the equipment get destroyed when temporary resolves?

Ruling: Yes, Spinning Axe will be destroyed when the temporary trigger resolves, even if it was attached to a unit before the trigger resolved.

Nuances:

• Reminder text is not rules text, so the "if this is unequipped" reminder text doesn't affect how temporary works
• Attaching the equipment turns off its rules text, but this happens too late to affect the trigger that's already on the chain
• If there were an awakening trigger (like Irelia, Fervent while sealed), you could attach the equipment before the trigger goes on the chain to avoid temporary
• Another option is to wait for your opponent to play something after they kill the equipped unit, allowing you to re-attach in response
