Yukora, the Prisoner

A 5/5 for four mana with no evasion and no protection is already underpriced by black's usual standards; the cost is buried in the exit clause. The leaves-the-battlefield trigger turns every removal spell, every chump block into combat, every edict into a board sweep against you, with the lone carve-out being your Ogres. That conditional is the whole point: this is the apex payoff for an Ogre deck, the creature whose body justifies the tribe and whose downside the tribe is uniquely positioned to ignore. Build wide on Ogres and the punishment is a non-event; splash a few off-tribe utility creatures and you are handing your opponent a board wipe stapled to your best blocker. The design is doing something quietly clever by hanging the drawback on the leaves-the-battlefield window rather than a death trigger: bounce it, blink it, or flicker it and the sacrifice still fires, so the card resists the usual tricks for laundering a drawback into value. It is a body that prices admission in a single creature type, paying the buyer back with one of the cheaper large beaters black has printed.
