In order to get a sense of how many cards across all Magic sets feature books in their art, I searched the Gatherer and Scryfall card databases using the following bibliographic key words: book, tome, codex, library, librarian, archivist, archive, page, read, scroll, biblio, folio, grimoire Out of around 22,000 cards, this turned up approximately 100 cards
As far as I can surmise from surviving records of old tournaments, the best result anyone ever had with Dredge in Standard was this list from Stuart Wright, who came in second at UK Nationals: This list still resembles a normal Magic deck a lot more than anything that's to come in this chapter, but it's already (like various graveyard decks before it) turning the idea of card advantage on its head
20 copies were given to a single prize winner in the late '90s, but never surfaced on the open market
The full card pool has many Artifacts now with the Guarded attachments like Stone of Elostirion and Orcrist
This also makes it the ultimate group hug commander because no other deck allows every player in the pod to be considered the winner
