Cursed Monstrosity

Pay a land card every time this flier draws fire, or watch it die on the spot. The protection clause is a tax rather than a wall: any spell or ability that targets the Horror demands you discard a land or sacrifice it, and that includes your own auras and pump spells, which spring the trap just as readily as an opponent's removal. The mechanic leans on the graveyard-as-resource thinking of its era, where a discarded land was rarely a wasted card. Threshold decks counted cards in the bin, flashback spells fed on them, and madness gave discarding its own payoff, so the cost of keeping this creature alive also stocked the yard with fuel. The friction sits in the repetition: a removal-heavy opponent can target it twice in a turn and strip your hand of lands, draining your land drops dry. The design asks you to weigh a 4/3 evasive body against your land count rather than your life total, a resource axis most protection effects never touch. It reads as a downside dressed as an upside, but inside a shell built to want lands in its graveyard, the discard is closer to a feature than a fee.
