Necrogoyf

Tarmogoyf reads every card type in every graveyard; this narrows the fuel to a single line, creature cards, and pays for that loss of breadth by wrapping a symmetric discard engine around the body. The upkeep trigger is the load-bearing clause: at the start of each player's upkeep, that player discards a card, which steadily feeds the graveyards this creature's power counts from. It manufactures its own scaling. The four toughness holds ground while the creature-card count climbs, durable enough to weather the setup a self-mill or reanimator shell needs to inflate the number. Madness here is not a payoff you point at the rest of your hand; it applies only to Necrogoyf itself. Its purpose is a discount: pitch the card to any discard outlet you already run, from Faithless Looting effects to a rummaging creature, and cast it for instead of . That reframes the goyf as something you would rather discard than draw, a five-drop body deployed for three mana at instant speed off a card clogging your hand anyway. The lineage is unmistakable: a black Lhurgoyf that trades its ancestor's spread across card types for depth in one, then bolts a self-discount and a graveyard-filling tax onto the swap so the stat that scales and the mechanism that scales it live on the same card.
