Can Solari Shrine trigger on an opponent's turn when you kill a stunned unit, even though it doesn't have the 'reaction' tag?

Ruling: Yes, Solari Shrine can trigger on an opponent's turn. When you kill a stunned unit on an opponent's turn, Shrine puts a trigger on the stack, and when it resolves you can pay the cost (exhaust shrine) to draw 1.

Nuances:

• Timing restrictions only prevent you from activating abilities or playing cards at discretion
• Triggers go off whenever their condition is met, regardless of whose turn it is
• The lack of a 'reaction' tag does not prevent triggered abilities from occurring on an opponent's turn
