Does casting Stupefy on a unit cause it to die immediately if the Might reduction would result in damage markers equal to or exceeding its new Might?

Ruling: Stupefy does not directly kill the unit when it resolves, but the unit will die immediately after Stupefy resolves during the next cleanup.

Sequence:

• Stupefy resolves and reduces the unit's Might
• The unit dies in the cleanup that follows

Nuances:

• Because Stupefy doesn't directly kill the unit, effects that trigger on death (like Immortal Phoenix) will not trigger from the Stupefy itself, but from the subsequent cleanup
