Might of the Ancestors

Might of the Ancestors is a Commander card through and through — the graveyard accumulation and wide boards that justify five mana for a sorcery only come together in longer games with higher creature counts. In 60-card formats like Modern or Pioneer, sorcery-speed mass-buff effects at this cost don't compete with more efficient pump or finisher spells, and graveyard synergies there tend to demand more immediate payoffs. Standard could theoretically support it in a tokens-plus-graveyard shell, but the five-mana ask is steep for a format with fewer resources per game. Legacy and Vintage have no interest — the power ceiling is simply too low. Oathbreaker mirrors Commander's dynamics on a smaller scale, where it can occasionally land, but the 20-life starting total makes closing games faster a priority that Might of the Ancestors doesn't always serve.
