Liliana's Defeat

The color hoser is one of Magic's oldest sideboard tools, and this one narrows the archetype to a single detail of flavor: black-on-black hate with a bonus reserved for one planeswalker's whole family. Red Elemental Blast and Hydroblast were the template, but those answered spells; this answers permanents, destroying any black creature or black planeswalker for one mana. The three-life bonus fires only when the destroyed permanent is a Liliana, a rules-text flourish that turns generic removal into something closer to a personal grudge against the flood of Liliana variants black keeps producing. That single black mana is as cheap as destruction gets, but the price is paid up front in the targeting line: it answers nothing outside black, which is the bargain every hoser strikes (total efficiency against the one thing it was built to kill, dead weight against everything else). What keeps the card durable is structural rather than cute. Black has stayed a creature-heavy, walker-heavy color across nearly every era since this kind of card first appeared, so a one-mana destroy effect pointed squarely at those threats keeps finding work whenever a black deck needs to break a mirror it cannot win on the front side. The Liliana clause is the memorable part; the unconditional destroy is why it stays in the box.
