Bitterheart Witch

A tutor that only fires on death, for a card type that almost nobody builds around. The deathtouch is the engine, not a combat keyword: it turns the 1/2 body into a guaranteed trade, and the trade is the point, because dying is how the Curse gets onto the table. That inverts the usual reluctance to chump-block. You want this thing to swing into something bigger, or to be sacrificed, because the death trigger is where the value lives. The catch is the payload. Curses are a thin, scattered card type built mostly for flavor, so the toolbox this searches is shallow by design, and the body is priced as if the search were stronger than the targets it can find. What makes the design notable is the structural rhyme with creatures that fetch an Aura on death: the same "die to dress up the battlefield" loop, redirected from your own creatures to an opponent's player. It is a recursion-of-effect engine wired backward, paying you for losing the creature instead of for keeping it alive. The reward is only as good as the Curse it lands, which is why this reads as a build-around keystone for a deck that wants to weaponize a marginal card type rather than a card you splash for the rate.
