Ringwraiths

The design here folds two jobs black usually splits across separate cards: a removal spell and a recursion engine. The enter-the-battlefield -3/-3 is routine midrange interaction attached to a 5/5 body, so the base transaction already trades on parity: a kill effect and a threat in one card. The legendary rider sharpens it, adding a three-life tax whenever the shrunken creature happens to be legendary, which turns the removal from board answer into board-plus-clock against the kind of decks that lean on singular commanders and named threats. The graveyard-return trigger is where the card gets strange, and it rewards reading the timing closely. It does not recur when the body dies; it recurs when the Ring tempts its controller, an ambient trigger tied to owning and advancing the Ring across the game. That decouples the recursion from the creature's survival entirely: a Ringwraiths that has already died and delivered its -3/-3 comes back to hand to be recast and fire the trigger again, as long as the Ring keeps ratcheting up. The 5/5 is almost incidental to that loop; what the card actually threatens is a repeatable removal-and-body engine paid for over the length of a game rather than in a single turn. Stack enough tempts and the enter-the-battlefield effect stops being a one-time answer and becomes a recurring tax on the opponent's board.
