Twisted Justice

The cleverness lives in the words "of their choice." Most edict effects let the opponent give up their worst body, and you settle for the trade. This one inverts the incentive by paying you for power. The opponent now wants to sacrifice their smallest creature to deny you cards, but if their board is nothing but a freshly cast threat or a single fattie, they hand you a fistful of cards for the privilege of killing it. The spell scales its payoff against exactly the creature the opponent least wants to lose, doubling as a draw spell that punishes a parked, top-heavy board. The price is the catch: six mana at sorcery speed is a steep ask to resolve a single creature, and against an empty board it does nothing at all. That gap, between a backbreaking blowout when they overcommit to one big threat and a dead card against a wide cheap board, is what gives the design its shape. Other Dimir control payoffs turn an opponent's own board into a resource engine the same way: hold them until a single removal spell is also a draw three or four. The blue half of the cost gives the game away. This was never a clean black edict but a control finisher dressed up as one, asking you to wait for the turn that converts their best creature into your card advantage.
