Some people are calling it "the end of the game as we know it." Indeed, it bears a striking resemblance to something I "predicted" in World War M, the fictional article I wrote in 2012 about what it would take to kill Magic

For three mana, Fraying Sanity is a Blue Curse that reads, At the beginning of each end step, enchanted player mills X cards, where X is the number of cards put into their graveyard from anywhere this turn. As above, thats great if youre in mill, but kind of rubbish otherwise
Locations I think all these cards are playable in two-color decks, providing color-fixing and an excellent mana sink if youve got mana available to use in the later parts of the game
