In Showdown, when both players deal damage, who decides which units die?

Ruling: Each player assigns their total might as damage to their opponent's units in whatever manner they choose. The attacker assigns first, then the defender assigns, then all damage is dealt simultaneously.

Sequence:

• Attacker assigns their total might to opponent's units at the battlefield
• Defender assigns their total might to opponent's units at the battlefield
• Damage is dealt simultaneously

Nuances:

• You cannot choose which of your own units die; your opponent chooses where to assign damage to your units
• Even if you want a specific unit (like one with Temporary) to die, your opponent controls that decision
