Fatal Grudge

The trick that makes this edict kill what you actually want is that it launders your own sacrifice into a matching condition. Most edicts (Diabolic Edict, Chainer's Edict) hand the whole choice to the opponent, so they pitch a token or the least valuable thing they control. Here you set the terms: sacrifice a permanent whose card type matches the thing you want stripped away, and the opponent is boxed into their own version of that type. Feed it a creature and they lose a creature; feed it an artifact and their artifact goes; sacrifice a planeswalker and one of theirs falls. Like any edict it makes the opponent do the sacrificing, so hexproof and shroud offer no protection: nothing about this spell chooses a specific permanent, which is exactly why protection from targeting does nothing. What separates it from the pack is the card-type constraint. A plain edict lets the opponent shed their worst creature; matching card types lets you point the effect at whatever type you can afford to trade away. The cost is that you have to feed it something real from your own board, which pushes you toward a permanent you were already happy to lose: a creature with a death trigger, a token, an aura on a doomed body, a Treasure. The extra card replaces the one you cast and cushions the two-for-one any sacrifice-plus-removal spell risks becoming. It welds the aristocrats instinct (turning your own dying permanents into resources) onto an edict whose reach is dictated by what you are willing to give up.
