If Yasuo moves to a different battlefield after his ability triggers (using Fight or Flight), does the damage dealt to the enemy unit get healed during cleanup?

Ruling: If you attack Yasuo, let his ability resolve, then use Fight or Flight to move him, the damage on the enemy unit will be healed at the end of the showdown because it's still a combat. Regardless that no combat damage is exchanged, the healing happens because if combat starts it must end.

Sequence:

• Yasuo is attacked and his ability triggers
• Yasuo's ability resolves, dealing damage to the attacking unit
• Fight or Flight is played to move Yasuo away
• At the end of the showdown, damage is healed because combat started

Nuances:

• Fight or Flight and Ride the Wind cannot be played as a reaction when Yasuo's ability triggers
• If Yasuo moves before his ability resolves, the ability would fail because the target is no longer "Here"
• Damage does not reduce might
