Emptiness

In Commander, Emptiness is a soft lock piece in sacrifice and token decks that can churn through their own hand faster than the table — three opponents means three players bleeding cards simultaneously, and the enchantment does real work even without a dedicated engine. Competitive constructed formats tell a different story: Modern and Legacy have cheaper, faster hand disruption that doesn't require board setup, so Emptiness doesn't clear the bar in those environments. Standard and Pioneer offer more forgiving competition, and a midrange or token shell could exploit it, but the card rewards synergy-dense lists rather than generic inclusion. Oathbreaker, like Commander, is where Emptiness earns its slot — the compressed game state and powerful signatures make the symmetry easier to break.
