Rakshasa Gravecaller

Exploit always asks the same question (what do I get for the creature I feed it?), and the answer here is unusually generous: sacrifice one body, get two back. The math is what separates this build from the rest of the exploit roster. Most exploiters hand you a one-for-one trade plus a stapled effect, so the creature you sacrifice is a real cost. This one turns a single creature into two 2/2 Zombies, a net gain in bodies before you even count the 3/6 that arrived to do the sacrificing. Feed it a token, a dying creature, or something whose enter-the-battlefield trigger you have already milked, and the exploit clause stops reading as a tax and starts reading as a sacrifice payoff in its own right. That 3/6 frame carries the rest of the card: a wall that survives most of what an aggressive deck can throw, which means the demon sticks around long enough for those Zombies to matter. It wants an attrition shell where fodder is both the input and the output, the kind of grindy engine where every creature is expected to die twice. Read that way, the exploit cost isn't a downside the card has to apologize for; it's the machine the whole design is wrapped around.
