When a defending unit with Shield from a battlefield effect (Fortified Position) survives combat, does it lose Might equal to the Shield when the effect ends, potentially dying to negative health?

Question

Accepted Answer

Ruling: The unit does not lose Might or die. After combat damage kills units, combat cleanup clears damage from units before removing the "defender" designation and associated Shield effects.

Sequence:
- Combat damage is dealt and units are killed
- Damage is cleared from surviving units
- "Defender" designation is removed
- Shield effects from defending end

Nuances:
- In the example, Blitzcrank ends as a 7 Might unit (5 base + 2 from Discipline) with no damage marked, not as a 9/1 or 7/1
