Tymaret, Chosen from Death

Devotion is normally a payoff mechanic: cast the black cards you were already casting and reap the reward when the count is high enough. Here the count becomes a defensive stat, so every black pip already sitting on your side of the board keeps the demigod's toughness climbing. Two black mana buys a body whose durability scales with commitments you made for other reasons, which makes it a stubborn early blocker that hardens exactly when a mono-black board is firing on all cylinders. High toughness only buys resilience against damage, though; a bounce spell or edict resets it, and because the creature is itself black, a heavy chunk of premium removal (anything that only hits nonblack) can't touch it, which is a quiet upside on top of the wall. The graveyard exile is the more interesting half. Hitting up to two cards from any yards, with a life bonus stapled to each creature card exiled, folds incidental disruption into a creature that also gains life against the aggressive decks it is best positioned to hold back. That pairing is tidy role compression: one two-drop that soaks a hit, strips delve and flashback fuel, denies reanimation targets, and pads a life total, none of it asking you to warp a decklist around it. The repeatable exile is priced to grind rather than run away, and the toughness scaling ties the body's stability to a board you were building anyway. It is a workhorse meant to reward black commitment, not to headline it.
