What it does

Flying, trample

Start your engines! (If you have no speed, it starts at 1. It increases once on each of your turns when an opponent loses life. Max speed is 4.)

At the beginning of your end step, you draw X cards and lose X life, where X is your speed.

Rulings

6 official rulings, in the order Wizards published them.

  • 2025-02-07

    “Max speed — [ability]” means “As long as you have max speed, this object has [ability].” If the granted ability functions in a zone other than the battlefield, the max speed ability does too.

  • 2025-02-07

    If an effect needs to know what a player’s speed is and that player doesn’t have a speed, their speed is considered 0.

  • 2025-02-07

    Start your engines! isn’t a triggered ability. Increasing your speed to 1 is something that happens as a state-based action as soon as you control a permanent with the ability. Notably, this includes gaining control of a permanent with the ability that another player controls.

  • 2025-02-07

    Your speed doesn’t change until a spell or ability says so, such as the inherent triggered ability that cares about opponents losing life during your turn. Notably, losing control of permanents with start your engines! doesn’t affect your speed.

  • 2025-02-07

    A player “has max speed” if their speed is 4.

  • 2025-02-07

    Each player tracks their speed (or lack thereof) separately. Increasing your speed has no effect on whether another player has speed.

Every version of The Speed Demon

6 printings, newest first. Prices are the market figures Scryfall publishes, refreshed nightly. A printing with no figure shows a dash rather than a zero, because Scryfall publishes none for some of them.

Prices from Scryfall, which tracks the TCGplayer and Cardmarket markets. They move daily and are a guide rather than a quote. Search TCGplayer for The Speed Demon. It runs a name search across every version, which covers the printings TCGplayer publishes no direct link to.

Aggregated from Commander games tracked in TurnZero HQ. Every figure counts decks and games only. No individual deck list, player or playgroup is identified. Win rates are withheld below 5 completed games, where the sample is too small to mean anything.
