When defending with a unit that has less might than the attacking unit, if the defender stuns the attacker, who recalls from the battlefield?

Ruling: If at the end of combat units remain from both players, then attackers recall. The stunned attacker returns to base and the defender successfully defends.

Nuances:

• This applies even when the defender has less total might than the attacker
• When an opponent moves into an empty battlefield and applies contested status, they become the attacker for that combat
• A defender can use Zenith Blade to slide into a contested battlefield after the opponent has moved there, and will still be considered the defender
• If the defender stuns the attacker in this scenario, the attacker recalls and the defender conquers the battlefield
