Titan of Eternal Fire

Commander is where Titan of Eternal Fire actually lives — Human-tribal decks and Dwarf-heavy builds run it as a finisher that converts a wide board into a damage engine without needing combat. In Legacy, Modern, and Pioneer it's legal but essentially unplayed; five mana for a 4/4 that requires a Human-dense board to do anything is too conditional against the speed and interaction those formats demand. Oathbreaker follows the same logic as Commander: viable in the right Human shell, irrelevant outside it.
