Do units with 0 might die when they take damage?

Ruling: Units with 0 might do not automatically die. They only die when they take damage, and the minimum lethal damage is always at least 1 point, even for a 0 might unit.

Sequence:

• A unit with 0 might can have damage assigned to it (minimum 1 point)
• When damage is assigned, the unit dies
• Units with 0 might do not die simply from having 0 might

Nuances:

• You can assign 1 point of damage to a 0 might unit as lethal damage
• Units with 0 might at a battlefield don't necessarily die last - they can still be assigned damage normally
• A cleanup occurs after each card resolves, so units check for death at those points
