Hero's Demise

The narrowing to a single word is the whole transaction: legendary. The card pays for clean, instant-speed, two-mana destruction by waiting on a target that may never walk onto the battlefield, which is what makes it either embarrassing or surgical with almost nothing in between. It belongs to a recurring black tradition of cheap kill spells priced down because their clause is so specific they read as blanks against the wrong opponent. What separates this one is how completely its restriction tracks the way the game itself has shifted. In eras when legendary creatures were a curiosity, "destroy target legendary creature" was a near-dead draw; as singleton formats built entire decks around a single legendary leader, that same line became a far more pointed answer than its printing suggests. The destroy template is also a plain destroy, with all the usual exits intact: indestructible shrugs it off, regeneration can turn it aside, protection from black blanks it on the way to the stack, and hexproof denies the target outright. None of that is fine print; it is the ordinary consequence of being a straight destroy effect rather than an exile or a -X/-X effect. The result is a removal spell whose value is dictated almost entirely by what is across the table rather than anything intrinsic to the card, and a quiet record of how much the meaning of "legendary" has changed across the decades you might cast it in.
