Trial of Ambition

Edict effects have always traded precision for breadth: you cannot pick the creature that dies, so the opponent feeds you their worst, and the card is only as good as the board state you cast it into. What separates this one from the long line of Diabolic Edict and Chainer's Edict before it is the second clause, which turns a one-shot removal spell into a reusable engine. The sacrifice trigger fires whenever the enchantment enters, so any effect that bounces it back lets you cast it again. The card builds in its own recursion engine: every Cartouche you control returns it to hand on entry, meaning the deck that wants this is the deck stapling aura-style buffs onto its creatures anyway, and each new attachment quietly resets a removal spell. That coupling is the whole design. Standing alone, it is a slow, conditional edict that demands the opponent have a creature and lets them choose which to lose. Plugged into the Cartouche shell it was built to anchor, it becomes a slow grind that picks off a blocker every time you suit up a threat. The friction is the timing: both triggers are mandatory and tied to entry, so the loop only advances at the speed you can deploy enchantments, and an opponent with an empty board gives you nothing for the trouble.
