Liliana's Triumph

Diabolic Edict for two mana, but pointed at everyone: it hits each opponent rather than a single target. That distinction is the entire cost structure of targeted-versus-untargeted removal, and it matters more than the rate suggests. An edict cannot be fizzled by hexproof, cannot be countered by protection, and does not care what the creature is; it just demands a body. The tradeoff is that the opponent hands you their least valuable creature, so this is a scalpel against a single threat (a lone commander, a hexproof beater, a token-less aggro board) and dead weight against a wide one. The Liliana clause is the sweetener that pays for the color's usual insistence that you commit to a plan: control a Liliana planeswalker and the sacrifice comes stapled to a discard, turning a one-for-one into a two-for-one that also happens to be a strong follow-up to a planeswalker you were casting anyway. Nothing about the discard rider requires you to build around it, though; strip the Liliana synergy away and you still have a clean, unconditional instant that answers the threats targeted removal cannot touch.
