If a unit has reduced might (e.g., Cithria Cloudfield at 1 power from Watcher's -3 debuff) and you remove a buff token to pay a cost, does the unit die or stay alive at 0 might?

Ruling: The unit stays alive at 0 might. Units only die if their damage is equal to or greater than their might, so a unit with 0 might and no damage on it will not die.

Nuances:

• While might reduction effects state that minimum might is 1, this minimum is only checked when the reduction is applied. If a unit later loses a buff, it can drop below 1.
• Any might value below 0 is treated as 0.
