The Unspeakable

A 6/7 with flying and trample for nine is fair-to-stingy stats on its own; you are not paying for the body so much as for the recursion bolted onto it. The combat trigger is the entire bargain: connect once and you buy back any Arcane card from the yard, which in practice means a Reach Through the Mists, a Peer Through Depths, or whatever splice host kept the cantrips flowing comes back for another lap. That loop is what justifies the rate, and it does nothing outside a graveyard already stocked with Arcane cards, so this is a capstone rather than a generalist finisher. It belongs to a moment when blue's go-wide, spell-velocity identity was expressed through a single named mechanic rather than the broad "instants and sorceries matter" shell that came later. As a finisher it asks the deck to have already won the attrition war, then hands it inevitability: every swing refills the hand. Big, evasive, and pointed at exactly one archetype, it functions as the trophy a fully assembled Arcane shell was supposed to be playing toward, not a card that travels to other decks.
