Whenever another nontoken creature you control dies, exile Liliana, Heretical Healer, then return her to the battlefield transformed under her owner's control. If you do, create a 2/2 black Zombie creature token.
+2: Each player discards a card.
−X: Return target nonlegendary creature card with mana value X from your graveyard to the battlefield.
−8: You get an emblem with "Whenever a creature dies, return it to the battlefield under your control at the beginning of the next end step."
Drop Liliana early as a 2/3 lifelink body, then flip her into a planeswalker the first time another nontoken creature dies. As a walker she grinds card advantage with +2 discard and reanimates threats with -X, eventually locking the board with her -8 emblem. You play a mono-black attrition/aristocrats midrange game, trading creatures to flip her and refuel from the graveyard.
Add fast mana (Dark Ritual, Sol Ring) and tutors (Demonic Tutor, Vampiric Tutor) to assemble engines faster, plus more free sac outlets to control when she flips. Lean into a reanimation package—Buried Alive, Entomb, Animate Dead—to cheat huge bombs into play early. Top-end can include game-ending reanimation targets and a Razaketh/Sheoldred suite to convert grindy advantage into a hard lock.
