Fire Elemental

Fire Elemental is legal everywhere but relevant nowhere. In Commander, a 5/4 body for five mana without a triggered ability, static effect, or combo relevance is below the baseline — the format's card density means you're always cutting something like this for a threat that does more. In Pauper, where commons compete hard for efficiency, Fire Elemental gets outclassed by creatures that trade up or generate immediate value. Legacy, Vintage, and Modern don't register it at all; those formats demand threats that win the game on the spot or disrupt the opponent, and Fire Elemental does neither. It sees play primarily in Jumpstart or introductory products where card pools are intentionally limited.
