If Yasuo is at a Bastion Fort, gets targeted by Falling Star, responds with Discipline (which resolves), then Falling Star resolves, and the player is at 2 HP when opponent plays Smoke Screen, does Yasuo die?

Ruling: Yes, Yasuo dies after Smoke Screen resolves because his marked damage becomes greater than or equal to his might.

Sequence:

• Discipline resolves
• Falling Star resolves (marking damage on Yasuo)
• Smoke Screen resolves, reducing Yasuo's might
• Yasuo's marked damage is now greater than or equal to his might, so he dies
