When both Sett's legend ability and Zhonya's Hourglass are triggered simultaneously by a buffed unit dying, can the player choose to use Sett's ability to save the unit instead of Zhonya's?

Ruling: Yes, the player can choose which replacement effect to apply first. The owner of the object being acted on determines the order that replacement effects apply when multiple replacement effects trigger from the same event.

• When a buffed unit dies and both Sett's legend ability and Zhonya's Hourglass would trigger
