Raving Oni-Slave

The drawback is bidirectional, and that bidirectionality is the entire wager: a 3/3 for two carries a tax that fires both when it arrives and when it dies, six life on the table across a single creature's life cycle unless you control a Demon to sponsor the contract. The fiction is the mechanic; the ogre is in thrall to a demon and goes feral without one, and the card prices that servitude in life rather than mana. What makes the body so cheap is exactly that you are meant to never pay: the design assumes you are building toward a demon payoff, with the Slave as discounted muscle that arrives free once the patron is in play. The bidirectional trigger doubles as a quiet trap on its own controller, since chump-blocking or sacrificing it does not escape the second three life if the Demon has already left the battlefield. This is an early example of a black design that gated aggressive stats behind a demon-tribal commitment, asking you to assemble the engine before the rate flips from liability into bargain. Run it without that scaffolding and you have signed a contract you cannot honor; run it with the patron in play and the drawback simply never reads.
