I think A Submerged Rector can be moved to Efficient Repeatable. Seems like the only reason the Rector is placed under Niche Repeatable is there wasn't a good source of Verses of Counter-Creed, but now you can easily <a href="/wiki/The_book_trade" title="The book trade">obtain them</a> in the Tracklayers' City and spend ~4 actions (at max Efficiency) <a href="/wiki/Noisily_subvert_the_entire_process" title="Noisily subvert the entire process">trading each for 36 Scrip</a>.
