Lich's Mirror replaces the game-loss event if you would lose the game in the following ways: -- As a state-based action for having 0 or less life. -- As a state-based action for having tried to draw a card from an empty library since the last time state-based actions were checked. -- As a state-based action for having ten or more poison counters (though this isn't that helpful; see below). -- Because an ability (such as the one from Immortal Coil) states that you do so.
