Im going to add how I feel about the card as in whether I like it, how much I do, or if I dont care for it
the first is that at least half of the cards in affinity would be in the cube without the affinity deck unlike Goblins or Elves (which are the next closest decks in terms of cards that make the optimal lists and that also have a cube slot regardless of whether the archetype is in there or not)

Initially, we already have Archivist of Oghma and Black Market Connections, which are well-established cards in the format and are present in the Baldurs Gate set, so they seem like great options (price aside)
You can replace Swan Song with Arcane Denial for a relatively small disadvantage
But the real kicker is that this card's passive ability kind of shuts down graveyard reanimation strategies, which is pretty wicked
