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.
I see what you mean now.
That falls under a similar situation as when a player’s last (non-derelict) ship is pinned. If the “future move action” is being actively prevented by something another player is doing, that end condition won’t trigger.
Another way to look at it is that if the ship was left entirely on its own without any outside interference, only then could it count toward that condition.
