Good judging!
I'm not sure you fully understand the drawback of Old Teacher. It's Pathfinding, but you get a copper with Buy in your deck for the trouble. If you gain it again, it only gets worse. You can say the junk isn't as big a deal as the gap between $6 and $8, but the "cost" is there.
Literati has some potential memory issues, but they aren't as common as you are thinking. It puts the card (that will be discarded later) on top of your deck immediately. This will sometimes cause memory issues when topdecking cards with $ or Actions, and very rarely cause ghost effects with Taskmaster or Cargo Ship (like Improve can), but I personally don't think those issues will come up often enough to present a significant problem. "Would discard from play" is used as an identifier to prevent topdecking Durations and thrones playing Durations.
I also added a link to the image inside the tool in my submission. I don't usually post images here so sorry that it didn't work.
