Can you use Voli Legend's exhaust ability in response to a Dazzling Aurora trigger that occurs during the end step?

Ruling: Yes, you can exhaust Voli when you play a mighty creature off of Dazzling Aurora, even during the end step. Voli's ability is a triggered ability, not an activated ability.

Nuances:

• Triggered abilities can be distinguished from activated abilities by the absence of a ":" symbol indicating costs
• Voli's ability can also trigger on your opponent's turn if you manage to get a mighty creature off then
