An ability that triggers when a creature becomes monstrous won't trigger if that creature isn't on the battlefield when its monstrosity ability resolves.
Nemesis of Mortals
Monstrous isn't an ability that a creature has. It's just something true about that creature. If the creature stops being a creature or loses its abilities, it will continue to be monstrous.
Once you declare you're casting Nemesis of Mortals or activating its ability, it's too late for players to try to change the number of creature cards in your graveyard to affect the cost of doing so.
