When Green Yasuo deals 6 ability damage to Orange Master Yi (who has +2 might from defending alone), then Yasuo is moved to base with Flash during the showdown, does Master Yi die? When does the +2 might passive end?

Ruling: Orange Master Yi survives. Flash does not cause the combat showdown to end, and the combat continues to full resolution including cleanup.

Sequence:

• Green Yasuo deals 6 ability damage to Orange Master Yi during the showdown
• Green Yasuo is moved to base with Flash
• Orange Master Yi remains at 8 might (6 base + 2 from defending alone) with 6 damage marked
• Combat showdown continues to completion
• During cleanup, damage is healed before "defender" status is cleared
• Master Yi heals to full while still at 8 might
• After healing completes, defender status ends and Master Yi returns to 6 might with no damage

Nuances:

• Once a combat showdown starts, it doesn't end until fully resolved, even if one player no longer has units at that battlefield
• Passive effects like the +2 might from defending alone (and Shield) remain applied until after the combat has fully resolved and units lose defender status
• Damage is healed before defender status is cleared during combat showdown cleanup
