Undercity's Embrace

The trouble with edict effects has always been that the opponent chooses what dies, which makes them lethal against a deck committed to one big threat and nearly worthless against a board flooded with bodies. This variant does not fix that math; it changes who is casting the spell. Bolted onto a Diabolic Edict is a body clause: gain four life if you already field a large enough attacker, no matter its color and no matter whether it is swinging. That rider quietly reshapes the card's home. A control shell wants the edict for its own sake and treats the lifegain as dead text; a deck already presenting a fat threat gets an edict that also buffers a race, converting a piece of interaction into a life swing. The upside appears only when a heavy hitter is already down, which is the honest part of the design: the two halves reward the same board state rather than propping up a weak one. You do not get the life when you most need it (an empty board with nothing big enough to trip the clause); you get it when you are already ahead on material. Edicts that scale with your own board tilt toward the deck pressing an advantage, not the one clawing back from behind, and taxing the classic effect one extra mana for that upside keeps it from becoming a universal instant-speed answer any black deck can slot in for free.
