If Yasuo Remorseful (6 Might) attacks alone against a 10 Might defender and both players pass with no actions, does Yasuo survive?

Ruling: No, Yasuo does not survive. Both units die. Damage does not reduce Might - a unit with damage markers still deals its full Might value in combat.

Sequence:

• Yasuo moves into battlefield, attacker triggers
• Both players pass priority
• Yasuo deals 6 damage to the 10 Might unit (unit now has 6 damage but still 10 Might)
• Priority passes to defender
• Both players pass priority
• Yasuo deals 6 damage to the 10 Might unit, killing it (total 12 damage on 10 Might unit)
• The 10 Might unit deals 10 damage to Yasuo, killing him

Nuances:

• There is no "HP" system in Riftbound - damage and Might are separate values
• A unit's Might value does not decrease when it takes damage; damage is tracked separately with markers
