Since M21, mill has become a keyword that appears all over Magic, especially on blue cards
This is a pretty incredibly upside, even if it only happens when three-quarters of the table is dealing with a figurative archenemy that isnt you
Moreover, as these cut cards are clearly not randomly selected given how they appear as a group, it makes perfect sense for them to have been omitted from Twilight Masquerade for a specific purpose
Dropped it for the same reason as Karmic Guide
So we made it in a way that, if the Oracle got you way above your starting 20 life points, it would also start buffing the other artifact creatures you control
Moving to an Artifact Pod in Repurposing Bay, making it blue, and making it unaffected by summoning sickness (sorry, Oswald!) makes this quite the home run
