Quote from palanthasDo you think there's any way Cogwork Librarian could work on MTGO, v3 or v4? I don't see how it could work in v3, which suggests to me that Conspiracy won't make it online (unless v3 goes dark first).
It doesn't actually have to work on MTGO the way it would in real life. The only reason it's drafted face up is to prevent cheating by swapping cards into a pack when you don't have a Cogwork Librarian but the pack has one. So on MTGO this isn't an issue because the software moderates the swapping itself.
Yes, you miss out on some information/signaling, but it still functions correctly.
