Kunoros, Hound of Athreos

Two graveyard hosers welded together, then bolted to a body that actively wants to be in combat. The first static clause locks out reanimation and creature recursion by keeping creature cards from entering the battlefield out of any graveyard; the second denies the whole class of graveyard-casting mechanics (flashback, escape, disturb, and the rest) by forbidding spells cast from the yard at all. Note what it leaves alone: activated abilities that don't cast and don't put a creature onto the battlefield, effects that return cards to hand, and other non-casting uses of the graveyard still function, so this is a targeted lock rather than a total shutout. Most graveyard hate is insurance you pay for up front: a Rest in Peace or Grafdigger's Cage that sits inert until the matchup that justifies it arrives, and does nothing else in the meantime. This design refuses that arrangement, because the tax on the opponent rides in on a 3/3 that pressures the board. The keyword suite is chosen with intent: menace demands two blockers to trade in combat, vigilance keeps the hate stapled to the board while you keep swinging, and lifelink refunds the tempo you sink into that pressure. The Athreos framing (the hound guarding the crossing between the living and the dead) is unusually literal for a design; the mechanical identity is denying anything the passage back over. Even against a deck whose graveyard never fills, this is still a three-mana attacker that swings, blocks, and gains life. The hate is the upside, not the whole point.
