Soul of Emancipation

Commander is where Soul of Emancipation earns its slot — a three-for-one removal spell with a body attached is exactly the kind of card that justifies the seven-mana investment in a 40-life, multiplayer game. In blink-heavy shells it becomes a repeatable board-control engine, and even a single trigger across three opponents pulls significant tempo. Legacy, Modern, Vintage, and Pioneer are all technically legal, but a seven-mana sorcery-speed permanent competes with formats that end games before turn four, so practical inclusion there is essentially zero. Oathbreaker's tighter deck construction and 20-life total make the cost even harder to justify outside of dedicated ramp builds.
