text: Lorehold Archivist's last ability checks at the moment it would trigger to see if there are three or more artifact and/or creature cards in your graveyard. If there aren't, the ability won't trigger at all. If it does trigger, the ability will check again as it tries to resolve. If you don't have three or more artifact and/or creature cards in your graveyard at that time, the ability won't resolve and none of its effects will happen.
