Grim Haruspex

Black has always paid full freight for card advantage: a card for a card, life for cards, or both. This sidesteps that arithmetic by routing the draw through creatures already dying for other reasons. The load-bearing word is "another nontoken creature you control dies." Tokens are deliberately walled off, which steers the card away from go-wide sacrifice fodder and toward decks running a stable of distinct bodies worth losing. Every blocker that trades, every creature fed to a sacrifice outlet, every chump in front of an attacker becomes a cantrip, and because it triggers on death rather than on the sacrifice itself, it pays out against opposing removal and board wipes just as readily. Morph is what protects the whole arrangement. Cast face down, the engine looks like an anonymous 2/2 and dodges sorcery-speed removal until you unmask it at instant speed, which means you can flip it in response to a wrath and bank cards as your board evaporates. That instant-speed reveal is the difference between drawing the cards and watching the engine die before it earns anything. The body is fragile enough that opponents are right to kill it on sight, but the disguise hands you control over when the engine comes online, and the death trigger means even the collapsing board it sits atop pays out when the trade finally arrives.
