If a buffed unit is reduced to 1 might by Smokescreen, then Call to Glory is played by spending that buff (reducing it to 0 might), does the unit die before Call to Glory resolves?

Ruling: The unit does not die. Units can have 0 or even negative might without dying - they only die if they have non-zero marked damage and their might is reduced to 0 or below. The unit would go from 0 might to 3 might when Call to Glory resolves.

Sequence:

• Unit starts at 5 might (4 base + 1 buff)
• Smokescreen reduces it to 1 might
• Call to Glory is played, removing the buff (reducing might to 0)
• Cleanup occurs but unit survives (no marked damage)
• Call to Glory resolves, granting +3 might
• Unit ends at 3 might

Nuances:

• A unit with marked damage equal to its might would die during cleanup after the buff is removed but before Call to Glory resolves (e.g., a 4 might buffed unit with 3 damage would die when the buff is removed, making it 3 might with 3 damage)
