If Shen (with buff, 4 might) and Sett, Kingpin (with buff from Shen, 6 might) both have Tank and are assigned lethal damage (4 to Shen, 5 to Sett) during a showdown, does Sett die when Shen dies and loses his buff?

Ruling: During combat damage step and cleanup in a showdown, units die and damage is healed immediately one after the other, so Shen dying does not cause Sett to die because damage is healed before Sett is reevaluated with his new might.

Sequence:

• Units with lethal damage are killed and placed in Trash
• Damage is healed from all units
• If an event during cleanup qualifies for another cleanup, it occurs after the first completes

Nuances:

• Outside of showdowns (e.g., with a spell like Singularity), there is no heal until end of combat, so Shen dying would cause Sett to be reevaluated with reduced might and his current damage, potentially killing him in the subsequent cleanup
