Oath of Liliana

Half of this enchantment is a clean edict: a creature comes off the opponent's board the moment it resolves, no targeting, no combat, just a forced sacrifice that ignores hexproof and shroud. That alone makes it a reasonable piece of three-mana removal. The other half is the part that names it: a recurring Zombie token that triggers only on a turn you landed a planeswalker, which means the card is two designs stapled together, one self-sufficient and one conditional on a specific build. This was one entry in a cycle of legendary Oath enchantments, each pairing an immediate effect with an ongoing bonus keyed to planeswalkers, an unusually direct attempt to give Superfriends decks a reason to play enchantments rather than just stacking walkers. The structure is the interesting part: the edict pays for itself regardless of whether you ever resolve the second clause, so the planeswalker payoff functions as upside rather than a precondition, and the card never feels dead in a deck that only wants the removal. The tension the design resolves is the perennial one for build-around enablers: how do you reward a narrow strategy without making the card unplayable outside it? Front-loading a universally useful effect and gating the synergy behind a separate, free trigger is the cleanest answer the era found.
