Does Smoke Screen's MIGHT reduction allow a lower MIGHT unit to trade with a higher HP unit, and how does MIGHT reduction differ from damage?

Ruling: Reducing a unit's MIGHT makes it easier to destroy in combat because it will die from fewer combat damage counters. A unit with reduced MIGHT will be destroyed when it receives combat damage counters equal to its reduced MIGHT value.

Sequence:

• Smoke Screen reduces Kai'sa from 4 MIGHT to 1 MIGHT
• When Recruit (1 MIGHT) attacks Kai'sa, it deals 1 combat damage counter
• Kai'sa dies because she only has 1 MIGHT and receives 1 combat damage counter

Nuances:

• MIGHT reduction is different from dealing damage; damage spells like Void Seeker deal damage but don't reduce MIGHT
• MIGHT reduction is different from stun effects; with stun you still need to "punch over" the unit's full stats
