When Ahri Inquisitive is on Reaver's Row and an opponent attacks, can I choose the order of the two 'When I defend' triggers so that Ahri's effect reduces the enemy unit's Might before Reaver's Row causes Ahri to retreat?

Ruling: Yes, you can achieve this outcome. You control both triggers, so you choose their order.

Sequence:

• Place Ahri's trigger on the stack first
• Place Reaver's Row trigger on the stack second
• Reaver's Row resolves first (causing Ahri to retreat)
• Ahri's effect resolves second (reducing enemy Might by 2)

Nuances:

• To get Ahri's effect to resolve first, you must order it so the battlefield trigger is placed on the stack first, since resolution happens in reverse order (last in, first out)
