If you reduce a card's might to 0 (or below) without damaging it, is the unit dead?

Ruling: No, a unit is only dead if it has non-zero damage at least equal to its might. Reducing might to 0 or even negative values without dealing damage does not kill the unit.

Nuances:

• Might can go negative (e.g., using multiple Frigid Touch effects)
• When might is referenced for other effects, negative might is treated as 0
• To kill a unit with 0 or negative might, at least 1 damage must still be dealt to it
