Overseer of the Damned

Removal-on-a-stick is an old black idea, but this one bolts a conscription engine onto the back of it. The enters trigger is the opening move: an optional kill that can point at anything, and if it hits a nontoken creature an opponent controls, it feeds the second clause on the way out. From there, every nontoken creature an opponent loses (to your blockers, your board wipes, your edicts, their own sacrifice fodder) hands you a tapped 2/2 Zombie. The restriction to nontoken opponent creatures does real balancing work, keeping the engine from spiraling out of a token-heavy table, but in a grindy attrition game it inverts the math of trading: each kill spell you cast can leave a body on your side instead of just one fewer on theirs. The tapped clause matters too, since the Zombies arrive as future resources rather than immediate ambush blockers, slowing the payoff enough to stay fair on the turn it fires. The design holds together in the marriage of the two halves: the 5/5 flier ends games on the clock, while the death trigger quietly turns the rest of the deck's interaction into a value loop, provided the targets it feeds on are real creatures rather than tokens. It is built for the black control shell that wants to win by outlasting rather than racing, where every opposing creature that dies is one more soldier conscripted into your army.
