I’m not quite sure how having additional Runes of Thor would change the scenario? They would each give you one additional guaranteed success with CCJ’s roll on a future turn, but Nemo’s Plans still wouldn’t be able to retain any of them.
It was in reference to attempting to block the “no future move actions” endgame trigger – going back to the initial question. However, since the MI roll could never be guaranteed with no Runes of Thor to ensure it (since the Runes would already be cancelled by CCJ before making the MI roll), it wouldn’t be a way to block it.
